Program Execution in Both Systems
This function detects an error in the external device or network of the systems (control system and standby system) by
executing a program that diagnoses external devices or networks of both systems.
The program set in "Both Systems Program Executions Setting" is executed on the CPU modules of both systems.
Ex.
When an error in the external device of the standby system is notified through a continuation error
Programs whose execution type is the fixed scan execution type or event execution type and safety programs cannot be
executed in both systems.
