(4) Precautions
(a) When forcibly keeping output status
To forcibly keep the output status (on or off) in the PAUSE status, provide an interlock with the PAUSE contact
(SM204).
(b) In a redundant system where the Redundant CPU is used
1) When the "Both systems" item is not selected on the Remote operation screen
Remote PAUSE operation is performed for only the CPU module in the system specified in the connection
target settings.
2) When the "Both systems" item is selected on the Remote operation screen
Remote PAUSE operation is performed for both CPU modules in the control system and standby system.
Make sure to set the Redundant CPUs in both systems in backup mode.
