PROCESS FOR DETECTING AND DOCUMENTING UNFULFILLED STEP-ENABLING CONDITIONS IN SYSTEMS CONTROLLED BY STEP-BY-STEP SPC PROGRAMS

摘要

The invention pertains to a process for detecting and documenting unfulfilled step-enabling conditions in systems controlled by step-by-step SPC programs, involving the following steps: monitoring the SPC program run for the occurrence of an unexecuted start or progression command and in response to the recognized occurrence of an unexecuted start or progression switching command: a) identifying the program module currently running; b) loading a first macro code of the current program module into a memory device, the macro code defining at least one start or progression condition and containing an address part that refers to a memory area in which is stored information necessary for analyzing the condition; c) simulated execution of the first macro code based on the code loaded into the memory device; d) recognition of whether the start or progression condition defined by the first macro code is responsible for the detected nonexecution of the start or progression command; e) at least in the event that the start or progression command defined by the first macro code is not responsible for the detected nonexecution of the start or progression command, repetition of steps b) to d) for a second macro code of the current program module; f) loading at least one macro code whose start or progression condition was responsible for the detected nonexecution of a start or progression command from the memory device into a display system; g) looking up in a table to find display information matching the start or progression condition of the given macro code, and h) depicting the display information on a display device of the display system.
