CI532V09/3BUP001190R1 ABB Control System Equipment

Description

Generally speaking, PLC is an extremely reliable device with a low failure rate. The probability of hardware damage or software errors such as CPU in PLC is almost zero; If the PLC input point is not caused by strong electrical intrusion, it will almost never be damaged; The normally open point of the PLC output relay, if it is not for external load short circuit or unreasonable design, the load current exceeds the rated range, and the contact life is also very long.

Therefore, when we search for electrical fault points, the focus should be on the peripheral electrical components of the PLC. Do not always suspect that there are problems with the PLC hardware or program. This is very important for quickly repairing faulty equipment and restoring production. Therefore, the focus of the electrical fault maintenance of the PLC control circuit discussed by the author is not on the PLC itself, but on the peripheral electrical components in the PLC control circuit.
