Abstract

When a technical process is monitored, messages from an automation system are continually transmitted to an operating and observation system. The messages are evaluated in the operating and observation system and displayed on a monitor. When a fault is recognized in the automation system, the location of the fault is displayed in a type of hierarchical progression. For this purpose, at least the important planning and design data of the automation system are accessible from the operating and observation system.

Claims

1. A method for monitoring an automation system and a technical process monitored and controlled by the automation system, the automation system being arranged in control cabinets, each of the control cabinets including at least one subrack which has modules, the method comprising steps of:

transmitting a message from the automation system to an observation system when a fault in the automation system occurs at a location;

accessing important planning and design data of the automation system, said planning and design data comprising at least information about locations related to all possible codes transmitted by the automation system;

determining the location of the fault in the automation system by comparing a code of said transmitted message with the accessed planning and design data; and

displaying a result of the determination on a display unit, wherein the displaying step includes the substeps of;

a) displaying a representation of one of the control cabinets in which the fault occurred, a representation of one of the at least one modules of the one of the control cabinets being visually emphasized in the display, the fault being associated with the one of the modules,

b) displaying a representation of one of the at least one subracks in which the fault occurred, the representation of the one of the modules being visually emphasized in the display, and

c) displaying a circuit diagram of the one of the modules.

2. A method for monitoring an automation system and a technical process according to claim 1, wherein said detected fault is a defective module or a wire breakage in peripheral circuit elements.

3. A method for monitoring an automation system and a technical process according to claim 1, wherein said observation system is an operating and observation system which has a rank higher than a rank of the automation system.

4. A method for monitoring an automation system and a technical process according to claim 1, wherein said display unit includes graphics capability.

5. A method for monitoring an automation system and a technical process according to claim 1, wherein said accessing step accesses all planning and design data of the automation system.

6. A method for monitoring an automation system and a technical process according to claim 1, wherein the monitoring method includes displaying several processes, and hierarchically graduated display of a fault location may be started from each process display.

7. A method for monitoring an automation system and a technical process according to claim 1, wherein the location of a fault is depicted in a graphics display.

8. A method for monitoring an automation system and a technical process according to claim 1, wherein the displaying step includes displaying a geographical location as well as displaying a circuit location of the detected fault.

9. A method monitoring the automation system and the technical process according to claim 1,

wherein the displaying step includes the substep of:

d) displaying a peripheral circuit of the circuit diagram, and

wherein the fault is associated with a particular circuit of the peripheral circuit, the particular circuit being emphasized in the display.

10. A method for monitoring an automation system and a technical process according to claim 1, wherein said monitoring method detects and displays electrical faults and program faults.

11. An observation system for monitoring an automation system and a technical process monitored and controlled by the automation system, the automation system being arranged in control cabinets, the control cabinets including at least one subrack which has modules, said observation system comprising:

a data storage unit which stores important planning and design data of the automation system, said planning and design data comprising at least information about locations related to codes transmitted by the automation system;

a processor which accesses said data storage unit and which evaluates messages transmitted by the automation system by comparing a code of said messages indicating a location of a fault in the automation system with the stored planning and design data of the automation system; and

a display unit which displays the results of the evaluation by;

a) displaying a representation of one of the control cabinets in which the fault occurred, a representation of one of the at least one modules of the one of the control cabinets being visually emphasized in the display, the fault being associated with the one of the modules,

b) displaying a representation of one of the at least one subracks in which the fault occurred, the representation of the one of the modules being visually emphasized in the display, and

c) displaying a circuit diagram of the one of the modules,

wherein said data storage unit and said display unit are coupled to said processor.

12. An observation system according to claim 11, wherein said fault is a defective module or a wire breakage in peripheral circuit elements.

13. An observation system according to claim 11, wherein said observation system is an operating and observation system which has a rank higher than a rank of the automation system.

14. An observation system according to claim 11, wherein said display unit includes graphics capability.

15. An observation system according to claim 11, wherein said data storage unit stores all planning and design data of the automation system.

16. An observation system according to claim 11, wherein said display unit displays several processes, and hierarchically graduated display of a fault location may be started from each process display.

17. An observation system according to claim 11, wherein the location of a fault is depicted in a graphics display.

18. An observation system according to claim 11, wherein said display unit displays the geographical location as well as the circuit location of the fault.

19. An observation system according to claim 11, wherein, after the one of the cabinets is displayed, a peripheral circuit of the circuit diagram is displayed, and wherein the fault is associated with a particular circuit of the peripheral circuit, the particular circuit being emphasized in the display.

20. An observation system according to claim 11, wherein said observation system detects and displays electrical faults and program faults.
