HOW TO MONITOR REDUNTANT SYSTEM
4.6 CC-Link IE Controller Network Connection (Network
System)
This section explains the CC-Link IE Controller Network connection (network system) that connects the GOT to the CC-
Link IE controller network.
The following shows an example of connecting the GOT set as a normal station to the CC-Link IE Controller Network.
(1) Connection method
Connect the GOT to the CC-Link IE Controller Network.
For details, refer to the following.
10. CC-Link IE CONTROLLER NETWORK CONNECTION
(2) GT Designer3 setting
Set GT Designer3 as described below.
To specify the station number which was set in the Q redundant setting in the device setting, set the station
number as the other station.
(3) Monitoring target change when system switching occurs in a redundant system
When system switching occurs, the network module station No.2 changes from a normal station to the sub
control station, and the system with the module takes over the control of the CC-Link IE Controller Network as
the control system.
Since the GOT monitors the control system, the monitoring target is automatically changed to the network
module station No. 2.
