摘要:
The invention concerns a test procedure for a control programme in source-code form designed to be executed by a computer. The source programme, which is written in a control language, is processed by a method in which statements concerning binary or arithmetic operations are grouped in functional blocks. The order of these functional blocks is permuted as a function of their dependence on each other so that a uniform sequence must subsequently result as a function of the individual programme functions. In addition, the processing method calls for the individual commands to be sorted in ascending order of magnitude of the number of their output or input. In a third operation, constants are converted into coherent measuring units. Subsequently, the control programme is compared with a reference programme which has also been processed by the method proposed. This enables differences between different versions of the programme to be easily detected and any changes necessary in the programme documentation can be derived from the differences. The fields of application of the invention include, for instance, complex plant processes, such as the control of power stations, in which the control software is developed and documented separately and adapted on site, as well as the development of code generators for graphical planning tools.

The invention relates to a method and a device for exchanging data on the basis of the OPC communications protocol, wherein at least one OPC-ready server (24) is connected parallel to a master OPC server (22). The invention proposes that an OPC client (28) is to be connected to the master OPC server (22) over a first communications link (26) and to at least one OPC-ready server (24) via at least one second communications link (24). The OPC client (28) exchanges data over the first communications link (26) and the master OPC server, and over at least the second communications link (26) and at least one OPC-ready server (24) with automatic devices (16, 16'), and evaluates the data transmitted by the master OPC server (22) and at least one OCP-ready server (24). In the event of failure, the master OPC server (22) can be at least partially switched over from the OPC client (28) to at least one OPC-ready server (24) in such a way that the program can continue to run smoothly in the same place.

The invention relates to a method for monitoring the functionality of an automation system (2) of a plant comprising at least one main processor (4), parts of the plant being monitored and controlled using a user software (6), which is constructed of a number of program modules (PM1 to PMn) and which is run on the main processor (4). A co-processor (8) is assigned to the main processor (4), and a message (N1) is transmitted from the main processor (4) to the co-processor (8). When received, this message is used by the co-processor (8) to start a monitoring time (t1 to tn). When a subsequent message (N2) is received, this monitoring time (t1 to tn) is reset before said monitoring time (t1 to tn) has elapsed, otherwise a fault is identified once the monitoring time (t1 to tn) has elapsed.

The invention relates to a method of drafting a program code (52) of control and instrumentation technology for operating a plant by means of industrial components (14, 15, 16, 17, 18, 19, 20). Said program code (52), in its graphical representation, comprises a plurality of sub-plans (27). According to the invention, the program code (52) of the control and instrumentation technology and the industrial components (14, 15, 16, 17, 18, 19, 20) are represented together in a machine-readable technology plan (10). The sub-plans (27), especially the functional plans of the individual plane, are automatically generated from the technology plan (10), and the individual sequences (53) of the program code (52) are generated from the functional plans. The invention provides a method that makes manual drafting or manual correction project planning superfluous.

摘要:
The method involves generating a specific description of a technical system. The project planning objects are selected from an archive which is provided with predetermined project planning objects (30) using the specific description (200). The selected project planning objects are adjusted by the specific description. An independent claim is also included for a device for producing a specific project planning document for controlling a technical system, particularly for a project planning power plant control.
