4.3 Functions for Improving System Reliability
This section explains how to use the functions for improving the reliability of the CC-
Link system.
4.3.1 Disconnecting a data link faulty station and continuing the data link with only normal
stations (slave station disconnect function)
This function disconnects any of the remote stations, local stations, intelligent device
stations, and standby master station if it has become data link faulty due to power off
or other cause, and continues the data link among normal remote stations, local
stations, intelligent device stations, and standby master station (no setting is required).
