Reflection to external outputs of the standby system
The forced on/off is reflected to output devices of the standby system regardless of the operation mode and settings.
However, for external outputs of the standby system, the reflection is as follows depending on the operation mode and the
output setting of the standby system.
Operation mode
Backup mode
Separate mode
*1 Since cyclic data of the network module is not sent on the standby system, forced on/off is reflected only to the modules mounted on the
main base unit. (Forced on/off is not reflected to external outputs of the remote I/O module regardless of the standby system output
setting.)
Input/output behavior in forced on/off registration
The reflection of forced on/off does not differ depending on the system or operation mode.
■Forced on/off of input devices
Forced on/off is reflected to input devices when the END processing is executed. The following table lists the behavior of the
input devices within the refresh range or the input devices specified in the tracking transfer setting.

Behavior
Forced on/off is reflected to the input devices after the data is refreshed from the module.
Forced on/off is reflected to output devices after the transferred device data is reflected to the standby system.
Behavior
After forced on/off is reflected to the output devices, data is refreshed to the module.
Forced on/off is reflected to the output devices on both systems after the device data transferred from the
standby system is reflected.
