HOW TO MONITOR REDUNTANT SYSTEM
4.1.2 Computer link connection (Connection to serial communication module
mounted on remote I/O station)
This section explains the computer link connection that connects the GOT to the serial communication module mounted
on the remote I/O station of the MELSECNET/H network system.
The following shows an example of connecting the GOT to the serial communication module mounted on the remote I/O
station of the MELSECNET/H network system.
(1) Connection method
Connect the GOT to the serial communication module (QJ71C24, QJ71C24-R2, QJ71C24N, QJ71C24N-R2,
QJ71C24N-R4) or modem interface module (QJ71CM0) mounted on the remote I/ O station of the
MELSECNET/H network system.
For details, refer to the following.
7. COMPUTER LINK CONNECTION
(2) GT Designer3 setting
Set GT Designer3 as follows.
In this case, the GOT monitoring is performed by transient transmission of the MELSECNET/H network system.
Therefore, a longer time-lag occurs for displaying objects compared with directly monitoring the PLC CPU.
For displaying objects with a shorter time-lag, set the device for link devices B and W of the host station set in
the MELSECNET/H network and execute the cyclic transmission.
For details, refer to the following manual.
Q Corresponding MELSECNET/H Network System Reference Manual (Remote I/Q network)
(3) Monitoring target change when system switching occurs in a redundant system
When the system switching occurs, the multiplexed remote sub master station switched to the control system
takes over the master operation of MELSECNET/H.
Since the GOT monitors the master station, the monitoring target is automatically changed to the PLC CPU that
is operating as the master.
