    The invention relates to a method for operating an industrial control system and a corresponding control system, as specified in claims 1 and 15.
    Basically, two basic concepts are known in connection with control systems for operating and automating machines or comparable technical systems. On the one hand, it is possible to provide stationary, that is to say immobilized, control units. On the other hand, it is also known to provide, at least to a limited extent, mobile operating units, in particular operating units that can be moved to different locations by an operator. In practice, there are also industrial control systems in which both concepts are implemented. The stationary control units in such industrial control systems can be formed by control panels permanently installed on the machine, which can be formed from a screen for displaying system-relevant data or information and from a keypad for operation. In newer generations, an extensive keypad can be dispensed with and a larger screen with a touch screen can be provided instead.
    According to a common measure, mobile operating units can be permanently connected to the machine with a flexible, multi-core cable that has a certain length. The cable enables the machine or system to be operated or monitored from various positions. The operator is essentially limited only by the cable length in its local variability.

    There is an increasing desire on the part of industry to be able to connect such mobile handheld devices, if required, to a wide variety of machines or their control devices. Such handheld devices or control systems can therefore pay for themselves relatively quickly. In addition, from a control point of view, in many cases it is not even necessary for a handheld terminal to be permanently connected to the control device of the respective machine or system.
    Separately arranged connection boxes or connection units are also increasingly being formed, to which such mobile, wired control units can be connected and disconnected as required. With these connection boxes, a distinction can be made between hot-plug-capable and non-hot-plug-capable connection boxes. Hot-plug capability means that the mobile, wired control unit is switched on and off during operation. can be uncoupled without causing or necessitating an interruption of the control processes. Younger generations of such mobile control units can also be completely wireless and accordingly have relatively sophisticated radio communication interfaces. Especially in the case of the control units provided for wireless communication, there is considerable technical effort and extensive precautions are to be taken with regard to the effective range limitation and the pairing or the assignment method between such a mobile control unit and the control which can be influenced thereby.
    EP1404062A1 discloses a communication system with a plurality of subscribers connected to a data line, in particular in the form of machine controls. At various points in the wired network, connection units are provided which are provided for connecting a portable operating and visualization terminal as required. The respective connection units each include a unique identifier, which can be read out by an operating and visualization terminal connected to it. This readable, unique identifier in the individual connection units enables a unique identification of the respective connection unit
    N2016 / 11800-AT-00 assigned machine control can be achieved. In particular, this unique identifier connects the portable operating and visualization terminal to the intended machine control in terms of data technology or assigns it to the correct system area. This document therefore deals with the selective registration or unambiguous assignment of a portable operating and visualization terminal to a specific machine or to its control device.
    Similar control systems, in which a unique identification is transmitted from at least one stationary control device or from a stationary connection box to at least one portable terminal to enable the registration or assignment process, are known for example from JP04085952B2, JP04990504B2 or EP1659466A1. All of these documents deal with the registration of a portable, electronic terminal to a specific machine or to a specific control device and with the sending of an identification to the mobile terminal.
    In addition, control systems with technical measures are known from the prior art which are used to establish a data-technical connection between a portable terminal and a machine or its control that is as secure as possible against errors. A clear, unmistakable identification is exchanged between the portable terminal and the machine control system, i.e. transmitted bidirectionally. Such pairing measures are known, inter alia, from DE10110776A1, EP1866712B1, DE10201002578A1 or EP1716982A1.With these pairing measures, a secure or unambiguous assignment can be established between a portable terminal and the respective machine control system, but there are other aspects which remain for a safe one or operating a comprehensive control system as safely as possible. In particular, problems can arise in connection with technologically mixed control systems or in connection with gradually expanded control systems, for which no practical solution is known to date.

    The present invention has for its object to provide an improved industrial control system and a method for operating a control system, wherein the corresponding control system can comprise a plurality of stationary control devices for machines and a plurality of selectively connectable types of mobile handhelds, and in spite of a possibly occurring technological mixed operation in connection with differently designed mobile hand-held operating devices, an operationally reliable or, as far as possible, error-avoiding operation of such a control system can be guaranteed.
    This object of the invention is achieved by the measures according to claim 1 and by a control system with the features according to claim 15.
    An advantage of the measures according to the invention is that it can be used to create an industrial control system in which the concept of the mobile hand-held control devices that can be connected and disconnected as required, in particular the wireless devices, but also the cable-connected devices that can be connected and disconnected as required, relatively easily can be implemented. Different normative requirements can also be met or ensured by the measures according to the invention if an operator intends to incorporate technologically different or from different manufacturing periods handhelds into the control system via their potentially communication-compatible interfaces. In particular, the measures according to the invention make it possible to use different types, but always suitable, of series of mobile hand-operated devices, in particular different versions of terminal devices, which may also have different software versions, without causing safety-related problems.
    The measures according to the invention ensure that before the establishment of a control-technical interaction, during which potentially dangerous control commands could be carried out, it is checked whether the respective combination between the mobile hand-held device and the control device ensures safe operation of the control system or
    / 40
    N2016 / 11800-AT-00 enables or guarantees the respective machine or system. This means that before the establishment of an interaction in terms of control technology, an at least partially automated or fully automatic check of the hardware and software compatibility between the mobile handheld device intended for connection or coupling and the respective control device or the corresponding control system takes place. With this preliminary compatibility check, a high overall security of the control system can be achieved. For example, in this way it can be avoided that, despite a mobile handheld device that can be fundamentally connected in terms of communication technology, there is no active control-related connection or the operator is prevented from being able to intervene in the control or movement processes if the various normative specifications and safety requirements are given by the respective combination or by the technological version of the mobile handheld device cannot be fulfilled. This is accomplished in a simple manner by the transmission of a data technology identifier starting from the hand-held operating device to the respective control device or to the control system and by the evaluation of this data technology identifier on the part of the control device or the control system, this identifier being hardware and software parameters of the Handheld includes. This compatibility check based on a special technical data identifier, which characterizes the respective technical version of the mobile hand-held device, can be implemented easily and relatively inexpensively, so that the costs for implementing such a control system can be kept as low as possible, despite a considerable gain in comfort and safety.
    In addition, with the measures according to the invention, the normative requirements for an automated technical system or its control system, which often differ for different countries, can be met in a reliable and practicable manner, and ultimately a high level of operational safety can be achieved by correspondingly implemented control systems , Among other things, extensive compliance with country and / or plant-specific requirements or criteria for a / 40
    N2016 / 11800-AT-00 safe operation of a control system can be ensured particularly reliably by the demanding measures with relatively little effort.
    The measures according to claim 2 are also expedient, since it can be used to determine automatically and at the same time in a fail-safe manner whether the mode of operation or the range of functions of the hand-held operating device corresponds to the technical features or requirements of the control system, in particular whether there is sufficient compatibility to ensure safe, normative requirements to ensure appropriate operation of the control system.
    Furthermore, the measures according to claim 3 can be used to automatically evaluate whether the hardware components and their operating software meet the requirements of the respective control device or the entire control system. To a certain extent, hidden incompatibilities, which could become critical in individual cases or special cases in time, in particular any possible dangerous situations for people or machine parts, can be reliably prevented.
    The same applies to the measures according to claim 4. In particular, it can be ensured that the safety technology or safety functionality implemented in the hand-held operating device corresponds to the requirements of the respective control device or control system.
    The measures according to claim 5 are particularly advantageous. As a result, the usability of the hand-held operating device in the respective control system can be checked automatically in terms of safety or safe use before potentially dangerous control processes can be influenced, controlled or created. In particular, with regard to different types of safety switching elements that can be implemented on hand-held operating devices, this can ensure that an optimal or safe and / or combination and interaction that corresponds to the normative requirements between the hand-held operating device or between its safety switching element and the stationary / 40
    N2016 / 11800 AT-00
    Control device or is constructed in relation to the entire control system. In the case of unsuitable combinations, at least one control-related influencing or delivery of potentially safety-critical control processes or control commands is automatically prevented according to the invention and the risk of dangerous situations is thus prevented. A loss of safety due to safety switching elements which are ultimately unsuitable or not optimal with regard to a machine or system to be influenced can thus be prevented particularly reliably.
    Furthermore, the measures according to claim 6 are advantageous, since the respective technical version of the safety switching elements installed on the various hand-held control devices is represented on the basis of the data technology identifier. In particular, this makes it possible to make a clear or error-free distinction in terms of different types or technical designs of shutdown elements, for example with regard to standardized emergency stop switches, general stop elements or three-stage enabling buttons with a panic stop function. In this way, it can be prevented, in particular in an automated manner, that a safety switching element or switch-off element that does not meet the safety requirements and that is implemented or installed on a handheld operating device provided for control-technical coupling is integrated in the control system or in the respective stationary control device in terms of control technology. This ensures that an operator using the handheld control device can promptly and safely carry out the respective shutdown or termination of the safety-critical control sequence or the potentially safety-critical movement of the machine or system in the event of a sudden dangerous situation. Furthermore, the respective normative safety requirements, which may differ from country to country and / or may vary from plant to plant, can be better taken into account and thus inadmissible or safety-critical combinations between a stationary control device or machine and a certain design or type of a handheld control device can be reliably taken into account and in particular be prevented automatically. It is essential here that the data-technical identification of the hand-held operating device is the respective / 40
    N2016 / 11800-AT-00 represents the technical version or safety category of the at least one safety switching element, in particular of the at least one switch-off element installed on the handheld operating device. The respective data-technical identifier should thus reflect the type or technical design of the safety switching element in such a way that an automated evaluation possibility regarding the intended structure of a control-technical interaction is reliably made possible.
    However, the measures according to claim 7 also automatically check the security level of the combination of the handheld operating device and control system or raise it to the required standard. In particular, safety-critical situations can also arise from the fact that unsuitable or only partially optimal control elements are provided in a hand control device provided for control-technical integration. Such is reliably prevented by the measures according to claim 7. For example, it would be a safety-critical concern if the control device or an adjustment or movement axis to be controlled with it requires a multi-axis control element, for example a two- or three-axis joystick, but only single-axis control elements are implemented on the handheld control unit, for example in the form of several, separately formed shift paddles or rotary controls for the various axes.
    The measures according to claim 8 are also of particular advantage, since existing control systems can thereby be adapted in a simple manner or upgraded relatively inexpensively in order to be able to implement the measures according to the invention. In particular, this allows existing control systems to be retrofitted in a simple and also relatively inexpensive manner. The connection unit can be understood as a peripheral additional or subcomponent of the respective control device or control system.
    In this context, the measures according to claim 9 are also expedient, since as a result the structurally independent connection unit can perform, among other things, the task of safety-related evaluation or
    / 40
    N2016 / 11800-AT-00 whose control or verification logic can primarily implement the corresponding safety functionality.
    The measures according to claim 10 result in an automated evaluation and the reliability of the check can thus be increased. In particular, user actions on the user side can thus be dispensed with or calls of checking routines initiated by the user can be avoided. This favors the overall security or reliability of the corresponding system.
    The measures according to claim 11 are also expedient, since in connection with an override of the safety functionality that has been deliberately initiated by an operator, occasionally the hand-held operating devices that do not or only partially correspond to the normative requirements are at least temporarily or temporarily integrated into the control system can. However, deliberate or manual activations on the connection unit or in the control system are required for this.
    The measures according to claim 12 are also advantageous, since this clearly signals to an operator whether the safety switching element installed on the hand-held operating device is functionally available, in particular in serious or Emergency can be actuated and then the control system or a corresponding machine or system can be converted into a safe state with high reliability or an immediate shutdown is made possible. Furthermore, this gives the operator feedback and thus provides a certain level of security, which can further increase user acceptance for the corresponding control system.
    The measures according to claim 13 are also expedient, since it makes it unmistakably recognizable for an operator whether the safety switching element implemented on the hand-held operating device is integrated into the control system in such a way that immediate deactivation and reliable availability of this deactivation function is provided if necessary. This can also increase the security of the corresponding control system. Such a / 40
    N2016 / 11800 AT-00
    Execution is particularly advantageous in connection with wireless or wirelessly connectable hand control devices to a control device or to the control system, but also expedient in the case of wired hand control devices.
    The measures according to claim 14 can be used to achieve a practicable evaluation of the admissibility or non-admissibility or the extent of the admissibility of the coupling of a handheld operating device planned or provided by an operator with respect to the respective control device.
    The technical effects and advantageous effects which can be achieved with the control system according to claim 15 can be found in the above and the following description parts.
    For a better understanding of the invention, this will be explained in more detail with reference to the following figures.

    An exemplary embodiment of an industrial control system 1 is illustrated in FIG. 1. Such a control system 1 comprises at least one stationary, electronic or electrotechnical control device 2, 2 ′. At least some of these stationary control devices 2, 2 'are assigned to different machines 3 to be controlled according to plan in terms of control technology or function. Accordingly, these control devices 2, 2 ′ can be used to control a complex industrial system 4, for example a production or assembly system, with regard to the respective processes. For this purpose, the at least one stationary control device 2, 2 'is connected to corresponding sensors and actuators of a machine 3 or system 4 to be controlled, as is known in a variety of designs from the prior art. A sub-component of such a system 4 can be a transport system, for example a conveyor belt, on which objects or workpieces to be processed are conveyed along individual processing stations. The individual processing stations can each comprise at least one industrial robot or another machine 3 that can be operated in an automated or partially automated manner.
    The individual stationary control devices 2, 2 'can be interconnected to form a control network by any data technology connections or network topologies. As is known per se, star-shaped, tree-like, serial and other network topologies or bus systems are possible. It is essential that the various distributed control devices 2, 2 'are at least partially networked with one another in terms of data technology and thus have a control-related connection or can interact and can thus handle a specific assembly or production process in the network. The respective control or regulation processes within the control system 1 or by means of the technical system 4 can thus be carried out automatically or at least partially automatically by means of the corresponding control or data technology network comprising a plurality of stationary control devices 2, 2 '. An assembly or machining process is shown as an example, in which four industrial robots, each with a control device 2 ′ which is functionally assigned to them, are used, / 40
    N2016 / 11800-AT-00 and a central control or control computer in the form of the stationary control device 2 is provided.
    The corresponding industrial control system 1 further comprises at least one mobile or portable, control-technical hand-held control device 5. Such a hand-held control device 5 can be moved or moved, in particular by an operator 6, and can therefore be moved to different places of use. As is known per se, such a handheld control device 5 can be used for monitoring and / or influencing control-related processes within the control system 1, in particular with respect to the respective control devices 2, 2 ′ of the respective machine 3, its machine parts, the system 4 or the various system parts , be used. Due to the location-variable transportability of the hand-held control device 5, the respective workflows or technical processes, which are carried out by the machines 3 or the system 4, can be better seen by the respective operator 6, in particular can be easily controlled or monitored.
    In order to be able to selectively influence or observe individual ones of the machines 3 or individual plant parts of the plant 4 in terms of control technology, the manual control device 5 is selectively connected to the respective control devices 2, 2 ′ in the control or data interaction can be moved. This corresponds to a data or Control-related assignment or registration process between the handheld operating device 5 and the respectively required or desired machine 3 or system 4, in particular with respect to the respective control device 2, 2 ′ of the respective machine 3 or system 4.
    For this purpose, the at least one control device 2, 2 'within the control system 1 comprises at least one data-technical interface 7, 7' for the production and termination, as required, of a control-technical interaction with a communication-compatible, control-technical handheld operating device 5. The data-technical interfaces 7, 7 'can be local can be directly assigned to the respective control devices 2, 2 ', or can be arranged at a distance from the respective electronic control devices 2, 2' and / or at a distance from the respective machines 3, so that for / 40
    N2016 / 11800-AT-00 an operator 6 can not necessarily be derived from the various positions of the interfaces 7, 7 'a functional assignment to the respective control device 2, 2'.
    In order to set up such a control-technical interaction between one of the control devices 2, 2 'and a portable hand-held control device 5 which in principle appears to be technically suitable for an operator 6, at least one data technology interface 8, 8' is also formed on the hand-held control device 5. This at least one data technology interface 8, 8 'is compatible, in particular communication-compatible, with at least one of the data technology interfaces 7, 7' of the various control devices 2, 2 '. The data technology interfaces 8, 8 'on the portable hand-held operating devices 5 can be formed by wireless interfaces 8' ', in particular by radio communication ports, and / or by wire-bound interfaces 8, in particular by cable-based, data technology plug interfaces 26, 26' '. Such plug interfaces 26, 26 'for the need to set up and remove a cable connection 17 can be directly on the housing of the handheld control unit 5 and / or in the vicinity of the respective stationary control device 2, 2', for example in the vicinity of a machine 3 to be controlled be provided, or be carried out directly on a housing of a machine 3 to be controlled. A clearly comprehensible or unmistakably recognizable assignment between a mobile handheld operating device 5 that can be connected and disconnected as required and a machine 3 or its control device 2, 2 ′ is therefore not always easy for an operator 6. This difficulty does not or hardly occurs in the case of permanently or permanently assigned hand-held control devices 5, but is in the case of generic hand-held control devices 5 which interact via their interfaces 8, 8 'with interfaces 7, 7' of stationary control devices 2, 2 'as required can, in particular can be used selectively, a challenge for the operator 6 or a risk of errors and thus a possible source of errors or dangers. These problems can be counteracted by means of special registration or pairing methods, as are known, for example, from DE10110776A1 or EP1866712B1, which goes back to the applicant. Nevertheless, it can be in operation or in the / 40
    N2016 / 11800 AT-00
    Management of such control systems 1 for complex technical systems 4 or for machines 3 which are difficult to understand come to greater challenges for the operator 6 and there is therefore a need for corresponding improvements, as will be explained below.
    As is known per se, an authorized operator 6 can use the mobile or portable hand-held operating device 5 to influence the processes, for example the movement sequences or the process sequences, of the individual machines 3 or of the entire system 4. For this purpose, at least one control element 9 which can be operated manually by an operator 6 is provided on the hand control device 5. Such controls 9 can be formed by hardware-related switching or actuating elements, in particular by joysticks, rotary wheels, trackballs, shift paddles and the like. The control elements 9 for influencing the control processes can also include so-called softkeys, which are implemented in software on the handheld control unit 5 and, in particular, can be shown on a touch-sensitive display 10 of the handheld control unit 5 if necessary or necessary. According to an advantageous embodiment, the display 10 or at least sections of the display 10 are formed by a so-called touch screen 11. Such a touch screen 11 thus represents - as is known per se - a combined input and output element with which control or data technology entries are made in relation to the control system 1 or in relation to the respectively connected control device 2, 2 ' and with which system-relevant information or data can be visualized at the same time.
    After potentially safety-critical or dangerous control commands can be issued by the at least one control element 9 on the hand-held control unit 5 or other serious process changes can be made with respect to a machine 3 or system 4, the hand-held control unit 5 has at least one safety switching element 12 that can be manually operated by an operator 6, 12 'trained. By actuating or activating such a safety switching element 12, 12 * on the handheld control device 5, depending on the version, / 40
    N2016 / 11800 AT-00
    - An initiation and / or termination of potentially safety-critical control commands or control processes. In particular, at least one enabling button 13 can be implemented on the handheld operating device 5, which for an effective initiation or for a definitive execution of potentially safety-critical control processes or machine movements by the operator 6 is to be actively or consciously operated or is to be moved into a predefined switching position , This minimizes the risk of unwanted or unintentional control commands or movement processes being initiated. Such a safety switching element 12 'in the manner of an enabling button 13 can also be designed in a multi-stage or multifunctional manner, depending on the technical design, and can also enable the immediate shutdown or termination of a potentially dangerous movement or control sequence. For this purpose, the enabling button 13 can either be released by the operator or, in the case of a multi-level or three-level enabling button 13, transferred to a separate, so-called panic or emergency stop position, in which an immediate termination of the dangerous processes or Movements are effected. This corresponds to an emergency stop or a panic stop command. Frequently, a plurality of selectively operable enabling buttons 13 are implemented at various positions on the hand-held operating device 5, each of which can be comfortably reached.
    Above all, if the mobile handheld control device 5 is also provided for issuing potentially safety-critical control commands or can be used to influence the processes within the control system 1, it can also be provided that at least one safety switching element 12 in the manner of a so-called emergency on the handheld control device 5 -Off switch 14 is formed. In particular, at least one of the safety switching elements 12, 12 'on the handheld operating device 5 can be defined by a switch-off element 15 which is provided for preventing or ending dangerous or accident situations and is accordingly identified and constructed. Such a switch-off element 15 on the hand-held control device 5 can be switched off in particular in the form of a standardized, red-yellow emergency stop switch 14, in the form of an off switch which can be illuminated or illuminated when the function is available, or in the manner of a general off switch
    N2016 / 11800-AT-00 leads. The respective embodiment can be influenced or defined in particular by country-specific specifications, by standards, by the design of the technical system 4 or machine 3, and / or by the way in which the hand-held control device 5 is connected to the control system 1. For example, the technical design of the switch-off element 15 can also be defined by whether the hand-held operating device 5 controls the control device 2 via a wireless communication connection 16 or via a cable connection 17 with the respective control device 2, 2 ′, in particular with the machine 3 or system 4 to be influenced. or to be coupled in terms of signaling. In particular, if there is a cable connection 17, which can also be made pluggable and disconnectable, the switch-off element 15 on the handheld operating device 6 can be formed by a standardized or standardized, red-yellow marked emergency stop switch 14. Especially when the hand-held control device 5 can be coupled or coupled to the respective control device 2, 2 ′ via a wireless communication link 16 and / or via a cable connection 17 that can be plugged and unplugged, the switch-off element 15 can expediently be illuminated by a functionally available device or red illuminated off switch. The switch-off element 15 can, however, also be formed by a general off switch, that is to say by switching elements which appear to differ in their external appearance from a standardized emergency switch 14. In particular, the external appearance of an off switch that can be illuminated depending on its functional availability or a general off switch is designed differently from the at least partially standardized appearance of a red-yellow emergency off switch 14.
    The respective technical design of the at least one safety switching element 12, 12 'on the handheld operating device 5 can be determined or determined by normative specifications, country-specific specifications, the type of communication connection to the control device 2, 2' (wired or wireless) and / or system-specific characteristics. influenced by. In particular, it depends on whether the control-technical interaction between the hand-held control device 5 and the respective control device 2, 2 'is via a cable connection / 40
    N2016 / 11800-AT-00 binding 17, or is established or established via a wireless communication link 16, the technical design of the safety switching element 12, 12 'on the handheld operating device 5 differs. In particular, depending on the functional reliability or technology of the wireless communication link 16, it can be critical if a red-yellow marked emergency stop switch 14 is present on the hand-held device 5 during a wireless or wireless operating state of the hand-held device 5. It can be seen from this that there can be different versions or types and versions of hand-held control devices 5, which are or would be communication-compatible with regard to their data-technical interfaces 8, 8 'to various control devices 2, 2', but which would, however, correspond to the respective environmental conditions or normative ones Requirements and / or the technical conditions of a machine 3 or system 4 to be controlled could not be fully met. This problem is corrected or held back by the appropriate measures.
    In order to be able to integrate the handheld operating device 5 into the control system 1 in terms of control technology, it likewise comprises at least one electronic or electrotechnical control device 18 based on at least one microprocessor or microcontroller. In particular, the control device 18 in the handheld operating device 1 can comprise a main processor 19, which is provided for the fulfillment or provision of functionally relevant, software-implemented functions. In addition, the control device 18 in a hand-held control device 5 for industrial control purposes can comprise a security processor 20, which can be connected to the main processor 19 in terms of data technology and is primarily implemented to fulfill security-related tasks or functions.
    To implement the respective functionalities of the hand-held control device 5, software or program code is stored in at least one memory of the hand-held control device 5. The respective software version determines the functionalities and / or the topicality of the implemented functions. In addition, hardware-related software components that are relevant for operation, in particular so-called firmware releases for various electronic components of the handheld device 5, / 40
    N2016 / 11800-AT-00 stored in manual control unit 5. For example, the radio communication interface 8 ', but also the other data technology interfaces 8, have electronic components with software-implemented functions. The firmware required for this is stored in suitable electronic storage units, in particular in EEPROMs of the various electronic components. The version or up-to-dateness of this firmware can be different within several handhelds 5. However, the so-called firmware version in particular can influence the range of functions or the respective firmware release for software-controlled electronic components in the respective hand-held control device 5 can influence its behavior. Likewise, the processes or functionalities of an independent security processor 20 in the handheld operating device 5 can be defined or influenced by firmware or software versions that are dependent on versions or updates.
    In the control device 18 of the hand-held control device 5, at least one identifier 21 for identifying the hand-held control device 5 with respect to the peripheral or external control devices 2, 2 ′ is also stored. This identifier 21 is typically stored in a non-volatile memory, for example in an EEPROM memory or in an SSD memory unit. As is known per se, such an identifier 21 or a specific component of the identifier 21 can also be used in the course of a control-related logon or integration of the hand-held control device 5 into the control system 1 for the purpose of unambiguous addressing or differentiation of the participants in the control system 1. This is especially the case if this identifier 21 or at least a certain part of the identifier 21 has a sufficiently high degree of uniqueness or unmistakability.
    In connection with the design of the control system 1 according to the invention, it is essential that this data-technical identifier 21 in the hand-held control device 5 at least identifies or represents the respective hardware version and the respective software version of the hand-held control device 5. In the course of establishing a control interaction or coupling between a hand-held control device 5 and the control system 1 or opposite / 40
    N2016 / 11800-AT-00 one of its control devices 2, 2 ', this data-technical identifier 21 is transmitted to the respective control device 2, 2' on the basis of the hand-held control device 5 provided for coupling, or is called up by the respective control device 2, 2 '. In particular, a so-called handshake takes place or the data-related identifier 21 of the hand-held operating device 5 is transmitted or made available, which data-technical identifier 21 is representative of the respective hardware and software version of the hand-held operating device 5. This identifier 21 is thus transmitted to the control system 1 or received by the respective control device 2, 2 ′. In the following, this identifier 21, which is read out of the hand-held operating device 5 and is representative of its software and hardware configuration, is evaluated by the control system 1 or by the respective control device 2, 2 'provided for the selective coupling, that is, evaluated in terms of data technology. Depending on these evaluation results, the behavior of the respective control device 2, 2 ′ or of the entire control system 1 is influenced or determined. In particular, the behavior of the control device 2, 2 ′ or of the control system 1 in relation to (i) admissibility or non-admissibility of the production of a control-technical interaction, in relation to (ii) functional behavior during, depending on the data-technical identifier 21 recorded in each case an active control-technical interaction and in relation to (iii) functional behavior in connection with an end of a control-technical interaction between the control device 2, 2 'and the handheld control device 5. In particular, on the basis of this data-technical identifier 21 or by evaluating it, it is determined whether a permissible or hazard-free coupling setup is possible between the respective hand-held control device 5 and the respective control device 2, 2 'and / or how the ongoing operation and / or how the termination thereof Coupling or the corresponding control-technical interaction must take place. This in particular in connection with the at least one safety switching element 12, 12 ', which can be installed in different technical forms on the handheld operating device 5. Similar issues may arise in connection with different types of control elements 9/40
    N2016 / 11800-AT-00 occur on various hand-held control devices 5, which control elements 9 are provided or suitable for the delivery of potentially safety-critical control or movement sequences.
    According to the invention, the identifier 21, which is characteristic of the respective hardware and software version of the hand-held operating device 5, is therefore used to detect or check in an automated or partially automated manner whether a secure control interaction which corresponds to the various specifications or security guidelines can or may be established. In particular, this creates a control system 1 that is particularly reliable in terms of function or as fail-safe as possible and at the same time user-friendly.
    In particular, it can be provided that the respective software version for the main processor 19 is represented in the hand-held device 5 by the data-technical identifier 21 of the hand-held device 5. In addition, it can be provided that the respective technical status for electronic components of the hand-held device 5, for example for communication-relevant components, is represented by the data-technical identifier 21 stored in the hand-held device 5. Furthermore, it can be provided that the respective firmware or software version of a possible security processor 20 is represented or characterized within the hand-held operating device 5 by the data-technical identifier 21. It is particularly expedient if the respective technical design of the at least one safety switching element 12, 12 * installed or implemented on the handheld control unit 5 is represented by the data technology identifier 21 of the respective handheld control unit 5. Various technical design options for safety switching elements 12, 12 * have previously been explained at least in part.
    Accordingly, the at least one safety switching element 12, 12 * on the hand-held control device 5 can be formed by a switch-off element 15 which can be actuated or activated by an operator 6 as required or in an emergency in order to prevent or end dangerous or accident situations. Such a switch-off element 15 can be, inter alia, in the form of a standardized, red-yellow emergency stop switch 14, in the manner of a light / 40 that lights up or is functional
    N2016 / 11800-AT-00 baren off switch, or be designed in the manner of a general off switch. The data-technical identifier 21 specifically stored in the respective hand-held control device 5 then represents in particular the respective type of technical implementation of the shutdown element (s) 15 implemented on the hand-held control device 5 and in the course of an envisaged registration or integration process of the hand-held control device 5 into the control system 1 evaluates this data-technical identifier 21 to determine whether the hand-held control device 5 provided for the connection is suitable for security purposes or at most unsuitable. This evaluation result can be different, depending in particular on the particular form or location of the control system 1 or the machine 3 or system 4. In the case of a plurality of security switching elements 12, 12 ″, there can also be a plurality of data-technical identifiers 21, or a more comparatively comprehensive data-technical identification 21 can be implemented.
    Analogously to this, the technical identification 21 can also represent the technical design of control-relevant control elements 9 implemented on the hand-held control device 5, in particular in relation to illuminated pushbuttons, key switches, joysticks, rotary wheels, 6D input elements and the like. This also has an influence on whether the respective hand-held control device 5 can be integrated into the control system 1 as risk-free as possible or in accordance with the normative specifications, or whether it cannot or should not be integrated. The respective data-technical interfaces 7, 7 'of the control devices 2, 2' can in principle also be compatible with the data-technical interfaces 8, 8 'if a communication connection from a security point of view between the respective version of the hand-held control device 5 and the respective technical version of the control device 2, 2 'would not be possible without risk or would not fully comply with the normative requirements and / or country-specific guidelines. This problem is eliminated or prevented by the measures described above or by the measures according to the claims.
    / 40
    N2016 / 11800 AT-00
    The at least one data technology interface 7, 7 'of at least one stationary control device 2, 2' can, according to a further embodiment, also be formed on a structurally independent electrotechnical or electronic connection unit 22. Such a connection unit 22 includes in particular an electronic evaluation device 23, which can be coupled to the at least one stationary control device 2, 2 ″ in terms of data or signals, in particular can be integrated into the entire control system 1. Such a connection unit 22 can - as shown schematically - be assigned locally to the respective machines 3 or systems 4, or else be positioned at a distance therefrom, and can be connected to the respective control devices 2 ′, 2 via control connections, for example cable connections. It is expedient if the evaluation of the data technology identifier 21 of the respective hand-held control device 5 in the connection unit 22, which can also be understood as a connection box, is carried out. The behavior of the control system 1 or the respective control device 2, 2 'based on the respective evaluation results is thus influenced by the connection unit 22. By forming an independent connection unit 22, an existing control system 1 can be expanded easily and subsequently.
    It may be expedient if, in the course of an intended coupling process between one of the control devices 2, 2 ′ and a specific embodiment of a mobile handheld device 5, the evaluation of the data-related identifier 21 is carried out automatically or compulsorily. It is provided that the control system 1 or the corresponding control device 2, 2 'in the absence or in the event of non-recognition of a data identification 21 on the part of a hand-held control device 5 provided for the control-technical connection into a safe state, in particular in the emergency-off state is transferred. This transfer can optionally take place with prior warning or by giving a notice to the operator 6. This can also be done with a timer in Verbin / 40
    N2016 / 11800-AT-00 dung, in particular a so-called watch dog can be integrated.
    Furthermore, a so-called override functionality can be implemented in the control system 1, in particular in the hand-held control device 5 or in the connection unit 22. It is provided that the behavior of the control system 1 is configured or adjustable by means of the connection unit 22 in such a way that a control-technical connection of a hand-held control device 5 is also possible if the hand-held control device 5 does not have a data-technical identifier 21 or a fundamentally unsuitable data-technical identifier 21. It may be expedient to be able to activate or activate this override function only through a conscious, active action by the operator 6.
    Analogously to this, or in a similar manner, it can be provided that the functional availability of the at least one safety switching element 12, 12 'on the handheld operating device 5 is evaluated by the control device 2, 2' or by the structurally independent or separate connection unit 22 and in Depending on a positive and / or negative evaluation result, the respective evaluation result of the operator 6 is suitably signaled on the control-technically coupled hand-held operating device 5. This can be done using text-based and / or graphic signaling or display elements. It can also be provided that a positive evaluation result on the part of the control system 1 or on the part of the connection unit 22 or on the part of the control device 2, 2 ′ is signaled directly on the hand-held control device 5. This can take place in particular via a switch-off element 15 which can be illuminated or which in the case of a positive evaluation result is actively illuminated. In particular, an evaluation-dependent activation of a preferably integrated lighting of the switch-off element 15 can signal an operator 6 whether a positive or permissible coupling between the hand-held control unit 5 and the control system 1 or the respective control device 2, 2 'could or was established and / or whether the corresponding shutdown element 15 is functionally available. In the case of a switch-off element 15 that can be illuminated, such a positive or permissible coupling process is indicated by / 40
    N2016 / 11800 AT-00
    Activation of the lighting of the switch-off element 15 signals which lighting is preferably provided for emitting red or reddish light.
    As already explained above, the specified technical measures can achieve a high level of system security. This is primarily in connection with the need to connect and disconnect mobile handheld control devices 5, but also in relation to so-called wireless terminals, that is, in the manner of wirelessly communicating handheld control devices 5. Different normative requirements, which apply in particular in different countries, can also be used. improved fulfilled or safely maintained by the various operators 6. Likewise, different types of mobile terminal devices with different optional operating elements 9 and different software versions in a control system 1 according to the invention cannot lead to a loss of security. In addition to optionally implementable control elements 9 on a handheld control device 5, there are also various forms of how the emergency stop switch 14 can be configured. The software versions of the decentralized or distributed connection units 22 can also be different within a group. In spite of this possible mixed operation and the various normative specifications, a control system 1 operated according to the invention always has a high level of safety and a behavior that complies with standards or according to plan.
    The proposed measures can therefore reliably meet or comply with various types of country and / or plant-specific requirements and / or normative regulations. For example, certain requirements or guidelines regarding the requirement of a standardized or red emergency stop switch14, the applicability of a general stop switch or the usability of an illuminable or luminous emergency stop switch element can be reliably met by the specified measures. Furthermore, regulations regarding the behavior of the control system 1 or a safety circuit of the control system 1 or the technical system 4 or machine 3 with regard to the behavior / 40
    N2016 / 11800-AT-00 can be reliably implemented when a hand control device 5 is connected and disconnected with a safety switching element 12, 12 '. On the one hand, there are control systems 1 in which when a hand control device 5 is unplugged with a red emergency stop switch 14, the safety circuit of the machine 3 or system 4 must be activated and then the respective machine 3 or system 4 in a shutdown state or in is placed in a safe state. Alternatively, there may be systems in which, when a hand-held operating device 5 is unplugged with a general shutdown element or with a gray stop switch, the safety circuit can remain deactivated, that is to say that no safety shutdown must or should not take place. In addition, there may be control systems 1 or machines 3 or systems 4, in which an illuminated or, in particular, functional availability, red illuminated emergency shutdown element 15 may not be used, or only such a shutdown element 15 may be used. These extensive or variant-rich regulations can be reliably taken into account by the data-technical identifier 21 and the sophisticated evaluation measures.
    The measures according to the claims can also ensure, in a simple and reliable manner, that the manual control device 5 connected to the control system 1 can and may interact with the machine 3 or system 4, and also ensure that there is definite compatibility. For example, depending on the control system 1 or the machine 3 or system 4, it may happen that certain control elements 9 must be present, that certain control elements 9 may not be used, that different software versions may not be used, and / or that wirelessly communicating handheld devices 5 may not be used, or only in a very small or restricted area of action next to the respective connection unit 22 or machine 3. Among other things, these regulations or requirements can be reliably met or met fail-safe by the sophisticated measures.
    The measures according to the invention thus enable improved compliance with an abundance of safety-related, system-specific and country-specific
    N2016 / 11800-AT-00 fish specifications - even though there are many options and the associated difficulties of mixed operation of different handheld devices 5 and different connection units 22. This difference can in each case relate to software-technical and / or hardware-technical aspects, as will be explained in the following with the aid of an overview of FIGS. 1 and 2. According to an expedient embodiment, an identifier 24 can thus also be provided in the connection unit (s) 22 of the control system 1, as is schematically illustrated in FIG. 2. This identifier 24, which is specific or characteristic with respect to the respective connection unit 22, is preferably present directly in the respective connection unit 22. In particular, the identifier 24 can be stored in a non-volatile memory device 25 of the connection unit 22. The data-related contents of the identifier 24 can be composed of the following parameters, the contents or values of which have to be adapted with a change in the hardware and / or software of the connection unit 22, these changes in contents or values also having to be changed in a country-specific and system-specific manner or to be adapted to it. With regard to the respective software version, the technical data identifier 24 can relate to the respective version of the firmware of the electronic components, and / or to the version of the software of the main processor, and / or to the firmware and software of a possibly implemented security processor of the connection unit 22. With regard to the respective hardware version of the respective connection unit 22, it can be provided that the data-technical identifier 24 reflects whether in the connection unit 22 a half-plug detection and / or a fully plug-in detection with respect to a plug interface 26 on the connection unit 22 or is implemented with respect to the respective control device 2, 2 ', and / or whether a current measurement or current monitoring is provided for the automated checking of a correct connection of a handheld operating device 5 to the respective plug interface 26.
    However, the technical data identifier 24 of the respective connection unit 22 or control device 2, 2 can also be composed of one or more of the country-specific and system-specific parameters listed below: a) ma / 40
    N2016 / 11800-AT-00 ximal number of failed connection or coupling attempts before an emergency stop initiation; and / or b) Behavior when plugging in a hand-held control device 5 which does not have a data-technical identifier 21; and / or c) Behavior when unplugging a handheld control device 5 with a standardized, red-yellow emergency stop switch 14; and / or d) behavior when disconnecting a hand-held control device 5 with a general stop switch; and / or e) Behavior when unplugging a hand-held control device 5 with an off switch illuminated with functional availability; and / or f) behavior when plugging in a hand-held control device 5 with a valid data-technical identifier 21; and / or g) Behavior when plugging in a hand-held operating device 5 with a red-yellow emergency stop switch 14, a general stop switch and / or an illuminated off switch. Furthermore, a list with valid data-technical identifiers 21 or parameter values of compatible manual control devices 5 can be stored in the storage device 25 of the connection unit 22 for the connection unit 22 or for its assigned control device 2, 2 ′.
    The handheld device 5 sends the internally stored, data-related identifier 21 directly to the connection unit 22 as soon as it is plugged in or immediately upon wireless coupling. The connection unit 22 then compares the received technical data identifier 21 or its contents or parameter values with the compatibility list stored in it or with the country and plant-specific specifications stored in it. From this, the behavior of the respective control device 2, 2 ′ or of the control system 1 is derived when plugging in and / or unplugging this hand-held control device 5 and / or during operation in cooperation with this hand-held control device 5.
    Possible behaviors when a) plugging in or connecting up, b) during operation and c) when unplugging or uncoupling a handheld control device 5 are as follows:
    Regarding a): If no data-technical identifier 21 is recognized when a hand-held control device 5 is plugged in or connected wirelessly, it can be provided that the control device 2, 2 'or the respective machine 3 immediately or after a defined period of time is in the safe state (emergency Off) passes. However, if / 40
    N2016 / 11800-AT-00 receive a technical data identifier 21, which indicates safe operation or a permissible combination, then the connection unit 22 switches on the hand-held operating device 5 or, in this case, a release is signaled to the respective control device 2, 2 ' or granted.
    Regarding b): With regard to the behavior of the control device 2, 2 ′ or the control system 1 during permissible or released operation with the hand-held control device 5, it can be provided that in the case of an illuminable shutdown element 15 or emergency stop switch Lighting, in particular its LED, is activated and, if necessary, its lighting function or signaling function is also monitored. Furthermore, it can be provided that in the case of compatible control elements 9 on the handheld control device 5, these can be activated or used or that in the case of incompatible control elements 9 these cannot be activated and cannot be used. In such a case, limited functions of the hand-held operating device 5, in particular its observation or visualization functions, can still be activated in relation to the respective control system 2, 2 '.
    Regarding c): Depending on the meaning or meanings of the data-technical identifier 21 of the hand-held control device 5, it can be provided that the respective control device 2, 2 ′ or machine 3 due to hot-unplugging in the course of unplugging or uncoupling the hand-held control device 5 Functionality continues, and / or changes to a safe state (emergency stop) due to the lack of hot-unplug functionality, and / or changes to an error state because a hand-held control device 5 was unplugged or uncoupled with a general stop button ,
    A feature of the measures according to the invention is that the hardware and software identically designed hand-held operating devices 5 have the same data-technical identifier 21. As a result, they also each cause the same behavior on the connection unit 22 or on the respectively assigned control device 2, 2 ′. The behavior of the control system 1 or the respective control device 2, 2 ′ is namely due to the data-technical identifier 21 or its / 40
    N2016 / 11800 AT-00
    Contents or parameter values influenced. The fact that the data-related identifier 21 is sent from the handheld control device 5 or made available on request and evaluated in the connection unit 22 or in the respective control device 2, 2 'is comparatively more expedient than the inverse principle, in particular in connection with the processes in FIG In the course of a disconnection or disconnection process of a hand-held control device 5.
    The respectively predefined behaviors of the control system 1 can be stored in the control devices 2, 2 ′ or in the connection units 22, the respective behavior being automatically called up or set depending on the data-technical identifier 21 of the handheld device 5 provided for coupling. The data-technical identifier 21 thus represents a kind of key information which is transmitted from the hand-held control device 5 to the relevant control device 2, 2 ′ or connection unit 22 in the course of establishing a connection or which is transmitted or transmitted by the hand-held control device 5 in advance of establishing that it can be influenced by control technology. must be provided.
    In particular, it can be provided that a list or data records of at least one of the connection units 22 are stored in a memory device 25 and, by automated comparison of the data-technical identifier 21 received by a handheld operating device 5 with this list or with these data records, a permissible or impermissible combination between the respective ones Control device 2, 2 'and this hand control device 5 provided for coupling is determined.
    The exemplary embodiments show possible design variants, it being noted at this point that the invention is not limited to the specially illustrated design variants of the same, but rather also various combinations of the individual design variants with one another are possible and this variation possibility is based on the teaching of technical action through the present invention Ability of the specialist working in this technical field.
