Only remote output (RY) is refreshed or compulsorily cleared according to the setting.
Remote input (RX) and remote register (RWr/RWw) are refreshed even if the switches on the CPU modules in the
master station and local stations are set to STOP, regardless of the setting.
● If the switch on a CPU module is set to STOP with "Clears Compulsorily" set, a compulsory output to a slave station
cannot be performed on a programming tool (by using a device test or other methods).
● The setting is enabled even if RY is refreshed using an intelligent function module device (Un\G) or TO instructions.
