Abstract: A toolbox for developing applications for debugging, tuning, and field-testing digital control systems is described. The operator workbench, i.e. the facility the control specialist uses actually to set up and test a system once the custom software has been generated, is also described. It comprises a commissioning utility and a multitasking run-time module. Underlying the structure of the run-time module is the concept of Petri nets, which describe in a natural way the concurrent and event-related activities of the control system, the interactive user interface, and the monitoring/data-logging utilities.
Keywords: digital control system workbench; application development toolbox; commissioning utility; user interface; monitoring utility; modular structure.
