28.14 External Input/Output Forced On/Off Function
Forced on/off is reflected to the input/output devices of both systems and external outputs by registering or canceling forced
on/off for the control system. (Forced on/off is reflected to both systems without setting tracking transfer setting in the CPU
parameters.)
Before executing the external input/output forced on/off function, check the versions of the CPU module and
engineering tool used. ( Page 1008 Added and Enhanced Functions)
Availability of forced on/off operations
Forced on/off operations are performed for the control system. However, registration status update can be performed for both
systems. (There is no difference between operation modes.)
: Operation possible, : Operation not possible
Register forced on/off for the control system.
Forced on/off registration information of the control system is transferred to the standby system.
Forced on/off is reflected to the input/output devices of both systems and the external outputs.
Forced on/off is reflected to external outputs of the remote I/O module through link refresh.
