Melsecnet/H And Melsecnet/10 Connections (Network Systems) - Mitsubishi Electric GT1685 Connection Manual

4.5 MELSECNET/H and MELSECNET/10 Connections
(Network Systems)
This section explains the MELSECNET/H and MELSECNET/10 connections (network systems) that connect the GOT to
the MELSECNET/H and MELSECNET/10 network system.
The following provides an example of connecting the GOT set as a normal station to the MELSECNET/ H network
system.
Network No. 1, Station No. 1
(Control station)

(System A)
(1) Connection method
Connect the MELSECNET/H network system to the GOT.
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
(3) Monitoring target change when system switching occurs in a redundant system
When system switching occurs, the network module station No. 2 changes from the normal station to the sub
control station and takes over the control of the MELSECNET/H network system.
Since the GOT monitors the control system, the monitoring target is automatically changed to the network
module station No. 2.
POINT POINT POINT
To monitor the control system without Q redundant setting
When system switching occurs, the network module station No. 2 changes from the normal station to the sub
control station and takes over the control of the MELSECNET/H network 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.
