Refresh behavior of programmable controller CPU
When a programmable controller CPU and a multiple CPU system are configured, register a multiple CPU synchronous
interrupt program (I45) on the interrupt routine, and enable the registered routine.
When a multiple CPU synchronous interrupt program (I45) is not registered on the interrupt routine or the registered routine is
disabled on the C Controller module side, the refresh function of the programmable controller CPU does not perform.
