Question
Are there comparison instructions that can be used as the input condition for other instructions in a ladder program?
Answer
In a CS/CJ-series Programmable Controllers 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 Programmable Controllers and C200HX/HG/HE-Z Programmable Controllers CPU Unit.
The C-series Programmable Controllers CPU Units do not support Symbol Comparison Instructions.
LD (LOAD) Type (CS1/CJ1 Only)
AND (Series) Type (CS1/CJ1, C200HX/HG/HE-Z, and CVM1-V2)
OR (Parallel) Instruction (CS1/CJ1 Only)
