Appendix4.1 Instructions with different specifications
This section explains how to modify the sequence program when the instructions with
different specifications are used.
Basically, the instructions which are not listed in this section do not require modifications.
• When M9053 is turned on, the Enable/Disable setting of the link refresh instruction
(EI, DI) can be performed.
• As the QCPU-A performs the link refresh in the END processing, enabling/
disabling the link refresh during the sequence program execution is not allowed.
Therefore, modify the sequence program.
(3) LEDA/LEDB instruction
(4) SUB, SUBP instruction.......... Unusable
• As the QCPU-A cannot store the microcomputer program, the SUB instruction is
cannot be used.
• To use in the QCPU-A, all the data processed in the microcomputer program area
has to be changed into those of the dedicated instructions.
(1) CHK instruction............ Modifications are required when the A1SHCPU or the
A2SHCPU is used in the refresh mode.
(2) DI/EI instruction............ Modifications are required when the special relay M9053 is
on.
