摘要:
A system and method for controlling operation of a plurality of elements in an automated process, such as a production process, and indicating error conditions as they occur. Each unique set of input and output conditions of the various system elements defines a unique logic state or zone. Thus, there are defined a multiplicity of valid system logic states or zones, each having a unique input/output image. A predetermined sequence of zones, productive zones representing designed machine operations, is stored in a zone table. All zones not explicitly defined in the zone table are automatically treated as error zones. A zone engine automatically cycles to observe any change in input/output image. Any change in inputs from the various system elements automatically transfer action to the unique zone associated with such inputs, resulting in corresponding changes in control outputs to the system elements and/or display an error message as appropriate.

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.
