Three programming methods are put forward for malfunctionalert handling . Practice confirms that these methods and measures improve the reliability of PLC control system.
In this article, a control system software is designed using digital PID algorithm, which realize real-time control, dynamic display, data record, parameter modulation and malfunctionalert etc.
