Cc-Link Connection (Intelligent Device Station) (Connection To The Cc-Link Module Mounted On Redundant Type Extension Base Unit) - Mitsubishi Electric GT1685 Connection Manual

4.8.3 CC-Link connection (intelligent device station) (Connection to the CC-Link
module mounted on redundant type extension base unit)
This section explains the CC-Link connection for connecting the GOT to the CC-Link module mounted on the redundant
type extension base unit.
The following shows an example of connecting the GOT to the CC-Link module mounted on the redundant type
extension base unit.

In this case, the GOT monitoring is performed by transient transmission of the CC-Link 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 RX, RY, RWw, RWr of the host station set in the
CC-Link network and execute the cyclic transmission.
For details, refer to the following.
3.3 CC-Link System Access Range for Monitoring
(3) Monitoring target change when system switching occurs in a redundant system
When the system switching occurs, the GOT automatically changes the monitoring target to the PLC CPU
switched to the control system.
