Programmable Logic Controller (PLC) of the workload of the design and

construction of the control system
Since the digital output plc using a relay control system software to replace a large number of intermediate relay, time relays, counters and other devices, the control cabinet design and installation of wiring workload greatly reduced. Meanwhile, plc controller manufacturer user program can simulate debugging in laboratory, but also reduce the workload of site commissioning. Also, due to the low failure rate micro smart plc and strong monitoring, modular, etc., so maintenance is also very convenient.
