Question

Are there instructions that directly make comparisons (e.g., "equal", "less than", "more than") so that comparison results do not have to be accessed from the status of result flags for comparison instructions?

Answer

The following Programmable Controllers support symbol comparison instructions (e.g., "equal (=)", "less than (<)", "more than (>)").

C200HX/HG/HE-Z Series

CVM1-V2 Series

CS/CJ Series

The execution condition for the comparison instruction must be created before the comparison instruction.
