Discussion about Methods of Transforming Relay Control System with PLC

Luo Gene

Abstract

The method of transforming the relay control system with PLC was introduced. Using the logic algebra , writes the relay control system first the logical relationship, then with PLC address substitution, obtains PLC the logical relationship, then obtains the LAD. Using this method transfonning complex relay control system can promote PLC accurately the LAD.
