PLC control cabinet is one of the advanced control methods in today's electrical industry, convenient programming, simple modification, compared with the traditional relay circuit to save cumbersome and complex wiring, while modifying the circuit, only need to change or adjust the program, the line can not change or less change; PLC has small size, space saving, convenient communication, can communicate with the host computer, man-machine interface, remote monitoring or operation, to achieve automatic control; At the same time, PLC can self-detect and diagnose system failures, and give early warning and tips in advance.
The advantages of PLC control over traditional relay control
1, the screen is intuitive, real-time monitoring, PLC with the touch screen, the touch screen screen can clearly see the operation of the field equipment, understand the current production status, the operator can adjust the production according to the current equipment operating status.
2, self-diagnosis, early warning, PLC has a self-diagnosis function, detected equipment overload, high temperature, voltage loss, short circuit and other alarms to remind the operator of equipment failure.
3, the line is simple, easy to program, process changes, only need to change the program, the line can not change or less change.
4, data records, alarm records, can record the state of the equipment during operation, such as the host current, oil supply temperature, oil supply flow, oil supply pressure, etc., data records can be used as a reference for process rectification during equipment maintenance.
5, small size, convenient communication, can communicate with the host computer, easy data acquisition and processing, can remotely monitor the operation of the equipment.
