Abstract
A control system for a programmable control device (10) executing a user program cyclically, wherein a data bit is provided in a memory space which can be accessed by a user program, the data bit is made 'ON' in an operation mode and made 'OFF' in a stop mode. The data bit is programmed with an AND condition for an output signal (Q1) to be made 'OFF' in the stop mode, and the operation mode is shifted to the stop mode only after having made the data bit 'OFF' and having executed the user program for one or more scans.
