The PLC originally developed and produced is mainly used to replace the traditional control device composed of relay contactor, but the operation modes of the two are different:

The relay control device adopts the hard logic parallel operation mode, that is, if the coil of the relay is powered on or powered off, all contacts of the relay (including its normally open or normally closed contacts) will immediately act simultaneously at any position of the relay control line.

The CPU of PLC adopts the operation mode of sequential logic scanning user program, that is, if an output coil or logic coil is connected or disconnected, all contacts of the coil (including its normally open or normally closed contacts) will not act immediately, and will not act until the contact is scanned.

In order to eliminate the difference between the two due to different operation modes, considering that the action time of various contacts of the relay control device is generally more than 100ms, while the time of PLC scanning the user program is generally less than 100ms, PLC adopts a different operation mode from ordinary microcomputer-scanning technology. In this way, there is no difference between the processing results of PLC and relay control device in the case of low I/O response requirements.
