Abstract

The operating and/or observing method uses an additional function block (9) provided within the installation control monitoring device (4), with a communication interface inserted between the monitoring device or a monitoring function block (8) and the associated operating devices (6,7), for evaluating the information for the latter and allowing it to be displayed directly. An Independent claim for a device for operating and/or observing an installation control monitoring device is also included.

Description

The invention is directed to a method and an arrangement to operate and / or monitor a device for Monitoring at least one coupled to a system Control unit from / to at least one remote, with the Monitoring device communicating control unit.

As the performance of available Re Kitchen appliances are used for this in the area of system control and monitoring constantly open up new applications net, and therefore increasing surveillance tasks delegated to automation devices. Were therefore initially only in the field of industrial manufacturing Automated tents of system parts, so with more modern ones Plant almost all parts in an automation concept be bound. Mostly there are individual plants assigned to complex separate control devices; these can however, to improve efficiency among themselves Informa Exchange functions, for example in the event of problems in a system partly allocate the production of the supplied parts at an early stage throttle or the like. This information exchange can either directly or via a higher-level communication direction, for example, also a central monitoring represents the possibility from which the difference the most detailed information about the various parts of the system can be queried and possibly also influenced. other on the one hand, in the case of large, spatially distributed plants various machines or other functional units ten operating devices required on site, for example at short notice To be able to change parameters or after removing a loca If the error occurred, the machine concerned was manually restarted to be able to. One has therefore moved to the supreme Control and operating structure of such systems after a Ser  to design the client principle, whereby one or more Ser calculates the desired parameter corrections in commands for the relevant control units installed on site put and send to this while the client machine each contain a program that controls the user interface A human-machine interface controls and manages and For this purpose, for example on the client computer concerned. commands and information entered via a keyboard in interpreted. Then from this program, for example ner operator requested information about the state of a plant part via the connected server computer concerned, if necessary, processed by the control unit concerned and visually represented to give the operator, for example, an In basis for the decision on which to change To provide process parameters or the like. Will represent then a parameter change is ordered, so this is Request, for example, in the information "Parameters to be changed" and "new value" separated and thus as an instruction transferred the server computer that this command into a for the control unit concerned understandable character sequence sets and sends to the selected control unit. There with the This procedure of the server computer no information about receives the various computing steps of the client computer, is, for example, a parallel operation of several Client computers not possible because the current user interface areas of the different client computers do not intermingle can be coupled. It is therefore an operator not possible, for example when starting up from a room Chen reasons to switch between two operating devices at short notice seln or in such a case must first on the new operator panel by various key combinations the relevant Be user interface can be set, which is the case with complex monitoring plants due to the diverse selection criteria to control a certain part of the system, relatively cumbersome is. Another disadvantage of this arrangement is that the various client computers with an extensive pro gram must be operated, which also a variety of In  information about the specific system and its control con must contain. It is therefore with every change of the An location and / or control structure required, in addition to Software of the control units and the monitoring server Computer also the software of the monitoring client computer to bring it up to date. This is a time-consuming job, especially at Inbe drive phases during the constant changes of the Re structure are required as extremely annoying have shown.

From these disadvantages of the prior art described the problem initiating the invention results, a possibility ability to create, like the structure of generic over security systems with at least one monitoring server Computer and preferably several connected monitors Improved or simplified client computers can be that on the one hand there is the possibility of ei the operator the individually and currently set loading user interface from one monitoring client computer to one to be able to "take" others with the least effort, and where in the event of a change in the system and / or tax structure, the user interfaces on the monitoring Client computers with regard to the structures that can be displayed, In formations and / or the executable operating actions with adapted to the lowest possible effort d. H. updated can be.

The solution to this problem is achieved by: the monitoring device or one connected to it NEN computer provided an additional function block, ins special saved in the form of an additional program is, which is like an interface module in the Communication between the monitoring device and the connected control devices and the on on closed HMI device evaluates directional information and processed in such a way that the then forwarded In  formations of the relevant operator panel in the manner of a Terminals can be displayed directly.

By this measure, the user interface of the closed monitoring client computer no longer ge locally controls, but from one in the server computer or one Cut installed directly on this connected device position module via the network. This is the information about the current status of the user interfaces of all acti from the client computer to the server computer, and Therefore, the one on an operator panel can currently be turned on provided the user interface at the operator's request be transferred to another operator panel. Because besides which is necessary for the construction of the user interfaces Information about the plant and / or control structure preferably also to the invention in which Be leave the installed interface module rich of the server are only necessary if these structures are changed a change in the interface module according to the invention or the data used by this, what is required in one move with the change of actual surveillance function block happen on the server computer concerned can. This completes the installation work to be carried out in the event of a change in the plant and / or control structure significantly reduced. At the same time, those of one Client computer activities to a minimum re reduced, namely on the forwarding of information from the higher-level server computer to a screen on the part and the information entered by an operator on the other hand, to the server computer. Because of this Client computer uses separate input / output modules like screens, keyboard, mouse, are from the egg actions to be undertaken on the client computer just that there is no difficulty in doing this required minimum program as part of the difference to make the most diverse operating systems executable. For this Reason and also because of the reduced demands on the  Hardware the client computer gives a user the ability to to be able to use cheap offers for this purpose NEN; furthermore, there is no fear that such client Calculator of the fast Veral common in the computer industry subject to the more complex calculation tasks are made exclusively on the server computer.

It has proven beneficial that the additional radio tion block the functions to be carried out by an operating device NEN, in particular calculation steps, at least partially takes. This shift in computing activity includes ins especially a shift of information from that Client machine to the server machine, and due to the sol to a greater extent centralized In formation it is easier on the one hand, appropriate Operating information from a connected client Computer to another, connected client computer ü over coupling, and also a central access is possible on the entire information of the surveillance network possible, making modifications of this information significantly be relieved.

It is within the scope of the invention that a as interface len function block used, additional program part for Execution at least partially in the main memory of the Ü monitoring device or the relevant, attached to this closed computer is loaded. Since usually also a to monitor used server computers via a closed screen as well as a keyboard is a "Minimal operation" of the monitoring system is also possible when all client computers are switched off. In this If the function block according to the invention is not required Lich, since the actual monitoring function block on the Server computer itself and thus operated directly that can. If the additional function block as a program Partly designed, it can be used to improve the performance characteristics of the server computer from its ar  be removed from memory; however, it must be reloaded as soon as at least one client computer in communication ons connection with the server computer occurs.

Further advantages result from the fact that the additional Function block, in particular multiple program part, in particular which can be addressed by different operating devices and in such a case, those assigned to the relevant control device performs individual calculations and results in the operator panel in question can be clearly assigned stores. Although the interface Function block operating multiple, connected client computers he is still able to make a strict appearance communication with the various client computers so that different operators at the same time completely independent at different client operator stations can program from each other. As a result, the Re repair personnel at the operator assigned to a machine advises to test the same or in again after rectifying the error Take operation while working on another HMI device in one other plant area, for example, correct other machine parameters can be yawed or the like.

It has been proven that the additional function block, in particular part of the program, various connected Be control devices individually. This measure also serves the decoupling of the various operating devices programming steps, so that despite the informat accumulation in the server computer the previous behavior of can simulate mutually independent client computers and si multiple entries are possible.

By adding the additional part of the program from the monitoring logic or with the monitoring program of the monitoring device different parameters, especially device addresses, can be addressed, the assigned operator panels can be individually be controlled duel. In this case, there is a clear  bidirectional communication between an operator panel and one control unit possible without the other HMI devices or client computers not requested information would be transferred to them. A similar function can, however, also of the interface construction according to the invention stone can be taken over by this from a control unit incoming information with the information from the various be compares the information requested and a This information is only forwarded if ei ne correlation between requested and arriving In formation exists.

It has been proven that the communication between the additional interface function block and monitoring Function block of the monitoring device on one Channel is summarized. Can be used as a transmission channel a memory area can be viewed, for example, after the FIFO principle described by the interface function block ben and is read by the monitoring function block, possibly together with another storage area for the ent opposite information. The targeted forwarding the information to the relevant control unit or to the currently assigned client computer can be determined, for example, using with transmitted code numbers or the like.

Furthermore, the additional interface function block multiple channels for communication with multiple monitoring Function blocks and / or monitoring devices on sen. A variety of taxes exist in the prior art devices from different manufacturers and each assigned monitoring function blocks, which in such a case on different monitoring server computers or also loaded on one and the same monitoring server computer and can be executed. In such a case, he can interface function block according to the invention have a sufficient number of channels for communication all control units with all function blocks  enable. For example. can such transmission channels as two FIFO memory blocks each for anti-parallel information directions of flow be formed.

The additional interface Function block for downlink communication (from the Monitoring device to an operator panel) as distributor, especially operated demultiplexers. This means it who that of one or more monitoring function blocks incoming information only to the interested party HMI device forwarded so that the possibly on the same Channel arriving from a monitoring function module Data on a selected output channel at a time Client computers are forwarded.

For uplink communication (from an operator panel to the monitoring device) the additional cut position function block as a signal merging module, for example in the manner of an OR coupling, but in particular as a multiplexer. Here they have to go to densel ben monitoring function block directed commands and in Formations of different client computers on one Channel can be summarized. If the relevant information tion, for example, of the interface Function block one of those in the monitoring function block recognizable code number is added, so can be ver use of the same code in the answer from the Ü monitoring function block easily a 1: 1 assignment the relevant control unit so that inputs from different client computers processed almost simultaneously can be.

The uplink-side communication preferably runs with priority steers off. This measure can help resolve conflicts, for example competing access to the same machine parameters be avoided. It can also be simultaneous and priority controlled accesses are interlinked, for example, in  to which the monitoring client distributed over a plant Computers can be assigned to individual plant areas and priority ge within such a plant area controls only one client computer to be active at a time can, however, in relation to other system parts, where predominantly or exclusively other machine parameters be modified, a simultaneous operation of several client Calculator is possible (each within the scope of your plant enjoy empire priority).

An advantageous arrangement can be found in that when assigning priority to one operator panel from another Operating device suppresses incoming information or in egg NEN assigned to the operator panel concerned ren cache are redirected. You can do this under be differentiated whether it is the incoming information are inquiries, and in such a case, despite otherwise i procures the desired information and forwarded while on the other hand instructions to change parameters may be suppressed or at least least be delayed to interact with each other exclude other operators.

The invention can be supplemented by the fact that all closed operating devices and, if applicable, associated memory areas, especially for the clipboard Information managed by the additional function block become. In this context, the term "Ver administration "the creation and maintenance of everyone as a client computer trained control device associated management data set with current information about the hardware in question For example, the size of the screen memory or the like, and / or the current status of the user interface, e.g. displayed Mask, position of a cursor, etc., can be understood. Fer Start addresses of memory areas can also be included can be understood at which the client Computer incoming information are cached  or information to be output is stored, for example the addresses of hardware interface modules and / or the addresses used in a network for the concerned client computer.

Another feature of the invention is that the first registration of an operator panel with an as Interface function block used additional Pro gram by calling up a relevant start address. This can preferably be a relative start address resse act based on the structure of a memory oriented in subdirectories and then from egg ner string consists of a command interpreter based on an index list of the relevant directory is found to find the current start address.

The invention also offers the possibility that a as Interface function block used, additional Pro gram when calling up an assigned start address Checks whether at least one operator panel is already logged on is, and if this is not the case, a Go through initialization phase and, for example, communication with the monitoring block of the monitoring device accepted. First of all, it can be determined whether a program used as an interface function block is already loaded in the main memory of the server computer, to see if the interface function block already is active in connection with another client computer. If this is not the case, it is under an initial phase of the interface function block is activated fourth, d. that is, stored in the main memory of the server computer the and the one or more monitoring function blocks reports.

In addition, when the call is made to the additional program assigned start address for the newly registered operator panel additional administrative data record created and, if necessary, a  Allocated memory area. After possibly the invention Interface function block in the previous section has been set up, is now when you register an additional Liche client computer an administrative data assigned to it set and possibly a memory area as information ons buffer reserved. Such a memory rich can have the size of a bitmap, for example, provided that Screen representation of the client computer completely from that Server computer is taken over. This is the fiction moderate functional block during the transfer of such determined image data to the relevant operator panel in the Able to turn to other tasks, so that a fast simultaneous operation with operation of several Client computer is possible.

According to the invention it is further provided that in the case of the new Message of an operator panel Information about its hard goods structure queried and in the relevant administrative data rate can be stored. While that on a client Computer implemented operating system of subordinate Be is, however, details of the hardware configuration ration of the client computer concerned, in particular via its connected peripheral devices, of importance be so that this when creating an administrative data zes can be queried. However, it is also possible to assigned to a clearly identifiable client computer Administrative record to continue to use if this after the last disconnection of the client computer concerned has been deleted.

The idea of the invention permits further training in that the additional function block is an execution part summarizes that called by the administrative part and with the ei information assigned to an operating device is supplied and then the calculation step actually to be carried out by this te takes over and as result information, for example, one into one Screen memory loadable bitmap or the like. The end  leadership part is called by the administrative part if an input to be processed from a client computer lies. This can be one with a line end Key completed information or command line or also an identifiable one entered with a mouse click Act function after completing the input of the Client computer was sent. This (command) information lies, for example, in a predetermined memory area of the server Calculator ready, the calculation steps to be carried out are in the execution part itself or in one attached to this closed database, and that for a proper according to the design, additional information may be required The execution part can be assigned to the assigned administrative data Remove the sentence. If the execution part says so The result of extensive data to be transferred quantity corresponds, this can be temporarily stored then for a peripheral interface module to be able to be transferred to the client computer concerned NEN, while the functional block according to the invention is already can turn to other tasks.

To provide the result information in a suitable format can testify from the execution part to those in the information stored in the administrative data record the hardware quality of the relevant operator panel, For example, the size of the screen memory or the like be gripped. The result information generated in this way is then already in one with the peripheral hardware of the Client computer compatible form before and must be from this finally to the relevant peripheral unit will wear.

The invention has an advantageous embodiment by that the result information of the execution part of the management part in a predetermined transmission data format converted and sent to the relevant operator panel becomes, for example, together with the note, a transmitted bitmap  to load into the screen memory. The accompanying note can be limited to specifying the target device, so that the client computer knows whether the information in question output on a screen or, for example, on a floppy disk drive are to be written.

To perfect the method according to the invention be provided that the data format in communication between the control units and the interface function block and / or the module performing this function corresponds to a standardized data protocol. By using A standardized data protocol can help create the Interface component according to the invention to a large extent to existing hardware and / or software components be resorted to.

Finally, it is in accordance with the teaching of the invention that the operating devices a pro in addition to an operating system Gram for displaying and / or quick evaluation of the received Data is loaded. According to Art nes browser be structured so that in the area of a Client computer both in terms of hardware and software finally, standard components are used can. An individual component that is used for decryption of transferred processing, in particular forwarding is appropriate, can then, if necessary, from the server computer be loaded if they are not already on a client Calculator is available. Such an individual component For example, the quality of one or more, user-specific have special functions in the context of the browser program. It is therefore advisable to register one when logging in for the first time (new) client computer a request from the server computer make whether the individual component is already on this Client computer is loaded, and then possibly in a for the operating system used by the client computer pas send form to provide. Because currently at new acquisitions a variety of programs,  u. a. standard browser programs are also included, are after connecting such a computer and installation on the included standard software hardly any individual Additional work required, rather the computer can almost immediately and thus also with the invention Program put into operation by unfamiliar persons the. The only special requirement is at best the existence of a compa to the network in question tiblen network card to ensure a smooth interaction of the to ensure various hardware components.

The interface function block according to the invention can be used as Implement a separate program part on the server computer be tiert, or it can be hardware related to this Lockable device can be designed, both over the Server computer can be initialized by an operator or the quality of your own computer with input and output has opportunity. As part of an independent construction steins, it is quite conceivable to implement the after functions into a ladder diagram functionality in the manner of an analog computer with exclusive use implementation of hardware components.

Other characteristics, details, advantages and effects on the basis of the invention result from the following Description of preferred embodiments of the invention as well as from the drawing. Here shows:

Fig. 1 is a block diagram of a first, operated according to the inven tion inventive arrangement; such as

Fig. 2 is a block diagram of a further arrangement according to the invention.

In the two figures of the drawing, different network structures 1 , 2 are shown , in which the invention can be used advantageously. The circuit part with solid lines corresponds to the minimum configuration, while the additions shown in dashed lines represent optional additional units.

In the minimal configuration according to FIG. 1, at least one control device 3 is provided for a plant part, which controls it according to an internal program. The respective state of the relevant plant part can be determined by an operating and / or monitoring device 4 and made visible to the control personnel, for example on a screen 5 connected to it. Furthermore, an offset of the operating and / or monitoring device 4 operating terminal 6 is provided, at least, can be realized with the same at a remote location functionality as with the input / or output capability and 5 of the operating and / or monitoring device 4 itself. To to interference from this and possibly further operating terminals 7 with the operation / or monitoring function block and 8 of the operating and / or wachungsgeräts 4 communicate, has this via an interface function block 9 of the actions of the various inputs and Output devices 5-7 and the operating and / or monitoring function block 8 are coordinated with one another.

It is an additional object of the interface function block 9, not to supplement an optionally in a network along with other operating terminals 6, 7 executable operating and / or monitoring function block 8 such that together men with standardized computers 6, 7 a Communication in the manner of a server-client network is possible. Here, the operating and / or monitoring device 4 serves as a server, which not only includes the actual operating and / or monitoring functionality 8 , but also the communication options on several, for example up to 50, client computers 6 , 7 extended.

To perform this first task, an interface part 10 is provided in the interface function block 9 , which is able to determine the source terminal 6 , 7 of data entered, for example commands or information, and the relevant data, for example, after being supplemented by to forward an identifier assigned to the relevant terminal 6 , 7 to the operating and / or monitoring function block 8 . It is then the responsibility of the latter to cause the connected control unit 3 to make a corresponding operational correction.

Embedded in the interface function block 9 is also an execution part 11 which is able to largely take over the computing power of the connected client computers 6 , 7 . This affects in particular the selection of the masks to be displayed on a screen of a client computer 6 , 7 and the arrangement thereof in the context of a user interface, so that, for example, a data stream corresponding to the desired image information is generated and by the interface function block 9 is sent to the relevant client computer 6 , 7 . Its only task is then to remove the target device from an attached note, for example "output on the screen" and then to forward the data stream to the correct addressee.

On the one hand, this has the advantage that all information about the current state of the individual user interfaces of all connected client computers 6 , 7 is present in the interface function block 10 and thus in the operating and / or monitoring device 4 , so that there is no larger information Difficulties in transferring this state from a client computer 6 to another client computer 7 when, for example, a maintenance or commissioning person changes location. Also, the type of information that can be output in the various screen masks can be modified in the simplest way in that, together with a changed operating and / or monitoring function block 8 , a correspondingly adapted interface function block 9 also advises the operating and / or monitoring device 4 is loaded. Changes in the area of the different client computers 6 , 7 are not necessary, so that modifications of a control structure 3 and resulting changes in the monitoring structure can be carried out with the least possible programming and installation effort.

The remote client computers 6 , 7 can be selected comparatively freely in terms of their hardware and their operating system, provided that the connected peripheral devices such as the screen, keyboard or the like correspond to a concept supported by the interface function module 9 . In addition to the operating system, the client computers 6 , 7 finally need a program for displaying and / or quickly evaluating the information received from the interface function block 9 and for sending completely entered information (after actuating a final key) to the interface function block 9 , In the ideal case, standardized browser programs can be used for this purpose, which can be supplemented with one or more individual components in the case of a specific application, in order to enable a bidirectional flow of information.

The coupling of the individual client computers 6 , 7 to the operating and / or monitoring device 4 is possible in a variety of ways, for example via data lines converging in a star shape on the server computer 4 , via a network with a ring structure, where each connected client -Computer has received an individual address, via infrared or radio interfaces, each with one or more channels, etc. Furthermore, it is also conceivable to connect a remote client computer 7 via a national or an international data network, the communication, for example. can be guided across oceans by means of satellites. It is of great advantage if almost any client computer hardware can be used with almost any operating system and all standard browser programs that can be run under it, so that standard components that may be common in other countries are included communication is not disruptive. Another advantage here is that standardized data protocols are preferably used on the connecting lines 12 . All of these measures lead to an unprecedented flexibility and universality, the operating and / or monitoring device 4 being able to be reached from almost any conceivable computer in order to monitor and possibly modify the operation of a control device 3 . A possibly required individual component can be loaded by the control and / or monitoring device 4 after the connection 12 has been established .

In Fig. 1 is further indicated that a connection between various server computers 4, 13, 14 is possible, which can be also preferably prepared by the novel interface function block 9. Via these connections, which can be carried out, for example, within the framework of an internal company network 15 or an external, national or international data network 16 , on the one hand the information required for optimal operation of the connected control units 3 can be exchanged, on the other hand it is possible to view information from a particular client computer 6 , 7 , in particular operating parameters of an otherwise monitored 13 plant part of the same company premises, or even operating parameters of a remote production facility via the Internet 16 , whereby it is also possible to influence these operating parameters is. This purpose is served Ka additional ducts of the interface function blocks according to the invention 9, in particular, a connection corresponding Funktionsblö blocks 9 on the other operating and / or monitoring devices 13, permit the fourteenth

The network structure 2 shown in Fig. 2 differs from the network structure 1 primarily in that the interface function block 9 is not implemented together with the egg tual operating and / or monitoring function block 8 in one and the same device here, but in egg nem own interface device 17 , which is designed, inter alia, as an independent computer and equipped with connected peripherals 18 , in particular a screen and keyboard. The interface device 17 is connected, for example, via a cable connection 19 to the actual operating and / or monitoring device 4 . The possibility of connecting various client computers 6 , 7 corresponds entirely to the options described above in the network structure 1 .

If, in addition to the connection channel 19 for communication with the adjacent control and / or monitoring device 4 , further inputs and / or outputs 20 , 21 are provided, one and the same client computer 6 , 7 can also be used to monitor and install 13 that is widely installed , 14 control units 3 reached and the operation there checked and modified if necessary. This connection to other operating and / or monitoring devices 13 , 14 can take place both via a company-owned intranet 15 and via an external internet 16 . In such a case the section of the present invention provide function block 17 has the quality of a multiplexer that originating from one and the same service device 6, 7 in formations to different operating and / or monitoring devices 4, 13, can pass on the fourteenth

A remote control option enables so-called "flying Terminals "realize, the operator with a pocket device (laptop or the like) on different servers in a system can access it without knowing the configuration data there NEN; it is only the establishment of communication and the correct addressing required. An update of one Such "flying terminals" is therefore never necessary.
