5. Instructions
The instruction specification is different in CQM1H series and CJ1M/CJ2M series.
The Appendix explains the difference in operand and flags. Refer to the Appendix for details.
･A-1 Instruction operations
Explains difference in instructions and operand. Least necessary adjustment after program conversion on
the CX-Programmer.
･A-2 Condition flag operations
Explains difference concerning the operation of condition flags at each instruction execution.
5.1 High-speed counter/pulse output instruction
This section describes the difference of High-speed counter/pulse output instruction and explains the difference
of pulse functions in CQM1H-PLB21 and CJ1M-CPU2*/CJ2M-CPU**
