Insert board: Sampling part includes sampling control board, AD conversion board and sensor :CPU, as the core of the system, completes data receiving, data processing and output

Control signal; The output part of some systems use DA template, the output signal is converted into analog signal, through the power amplifier drive actuator; Most systems will directly

The output signal is given to the output template, which drives the actuator to work. The communication part consists of a communication template and a host unit.

Because PLC itself has minimal possibility of failure, the system failure mainly comes from the peripheral components, so its failure can be divided into the following types:Input fault, that is, the operator's operation error;

■ Sensor failure;【 Actuator fault;- The PLC software is faulty

These faults can be analyzed by proper fault diagnosis method and monitored in real time by software, so as to forecast and deal with faults.

The fault diagnosis method of PLC control system
