Ethernet Connection - Mitsubishi Electric GT1685 Connection Manual

4.7 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
Monitor target
Control
system
(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)
Q Redundant Setting
*1 GT14 is not compatible with MELSEC-QS.
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, 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.
POINT POINT POINT
When monitoring control system without Q redundant setting (Only GT16, GT15 and GT14)
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.
