Outputting A Comparison Result Of 16-Bit Binary Data - Mitsubishi Electric MELSEC iQ-R Series Programming Manual

Outputting a comparison result of 16-bit binary data

CMP(P)(_U)
RnPCPU
RnCPU RnENCPU
(Process)
• The RnCPU and RnENCPU with firmware version "17" or later support this instruction. (Use an engineering tool with version "1.020W" or later.)
These instructions compare the 16-bit binary data specified by (s1) with the 16-bit binary data specified by (s2), and according
to the result (small, equal, or large), (d), (d)+1, or (d)+2 is turned on.
