<p>PURPOSE:To ensure the temporary stop of a sequence SC program for each operation of an equipment to be controlled just with a single stopping operation, by deciding the satisfaction of the trigger conditions in each executing cycle of the SC program and stopping temporarily the working SC program for each change of the input/output and internal information. CONSTITUTION:A control part 2 decides whether the temporary stop trigger conditions set by a user to an optional number of addresses are satisfied to not in each executing cycle of a sequence SC program. Then the part 2 stops temporarily the execution the SC program if said trigger conditions are satisfied. Then the SC program can be stopped temporarily in response to an equipment to be controlled by setting previously on optional number of output holding points. In such a way, the temporary stop is possible with the SC program for each change of the input/output and internal information performing the machine control and therefore the equipment to the controlled is operated for each operation. As a result, the development, control, inspection, etc. of a control system are carried out with high efficiency.</p> |
