(Process)
• [RnPCPU (redundant)] If the instruction is used in a program executed in both systems, there are restrictions on its operation in the standby system when the
redundant system is in backup mode. ( MELSEC iQ-R CPU Module User's Manual (Application))
This instruction performs execution or non-execution processing of a subroutine program. When the condition is satisfied, the
instruction triggers CALL for the subroutine. When the condition is broken, it triggers FCALL.
