When I Use The CX-Programmer FA Integrated Tool Package To Write A Differentiated Instruction To CQM1H PLC, It Results In An Error. Why?

As shown in diagram 1, only the CS/CJ-series CPU Units and CVM1/CV-series PLCs CPU Units can accept the differentiation option with input commands.

With other models, use DIFU/DIFD, as shown in diagram 2.
