Ethernet Connection

This section explains the Ethernet connection that connects the GOT to the Ethernet network system.
The following shows an example of connecting the GOT to the Ethernet network.
Network No. 1, Station No. 1

(System A)
■1. Connection method
Connect the Ethernet network system to the GOT.
Set the Ethernet modules of System A and System B (including NW No., station No, and IP address) to the Ethernet
setting of the GOT side.
For details, refer to the following.
➠
■2. GT Designer3 setting
Set GT Designer3 as follows.
Setting item
Controller Type
Device setting (Network setting)
MELSEC Redundant Setting
To specify the station number which was set in the MELSEC 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, Ethernet module station No. 2 takes over the control of the Ethernet network system as
the control system.
Since the GOT monitors the control system, he monitoring target is automatically changed to the Ethernet module
station No. 2.

When monitoring control system without MELSEC redundant setting
When system switching occurs, Ethernet module station No. 2 takes over the control of the
Ethernet network system as the control system.
Since the GOT monitors the station of the specified station number, the monitoring target cannot
be changed to the station No. 2 in response to the system switching.
As a countermeasure, create a screen to monitor the PLC CPU of the control system by
switching the station numbers between System A and System B using the script function.
