Are There Comparison Instructions That Can Be Used As The Input Condition For Other Instructions In A Ladder Program?

Introduction

In a CS/CJ-series PLC CPU Unit, compare instructions can be used as input conditions by using Symbol Comparison Instructions.

Symbol Comparison instructions come in the three forms, LD, AND, and OR.
The AND-type symbol comparison instruction can be used with the CVM1-V2 PLC and C200HX/HG/HE-Z PLC CPU Unit.
The C-series PLC CPU Units do not support Symbol Comparison Instructions.
