■Status of a remote device station, intelligent device station, local station, and standby master
station (when operating as a local station)
Data link status
When the CPU module of the master
station is set to STOP at an error ("Data
Link Setting at CPU Failure" =
"Continue the Data Link")
When the CPU module of the local
station is set to STOP at an error
When data link "Input Data

system is Link Faulty
stopped Station" (for

*1 If parameter settings have been configured using dedicated instructions, the data is held. If parameter settings have been configured
using an engineering tool, the data is cleared when Y is set to the refresh device of the remote output (RY). The data is held or cleared
according to "Output Mode upon CPU STOP" when the device other than Y is set.
*2 When Y is set to the refresh device of the remote output (RY) in the local station that has stopped, only the remote output (RY) in the
stopped local station is cleared. The data is held or cleared according to "Output Mode upon CPU STOP" when the device other than Y
is set. Data link is continued for the other local stations.
