Precautions when using the QCPU redundant system
When monitoring other networks, do not set the QCPU redundant system as a relay station.
If the QCPU redundant system is set as a relay station, the GOT cannot switch the monitoring target automatically
when the system is switched.
(A timeout error occurs due to failed monitoring)

Monitoring devices of other stations on the network
If devices of other stations on the network system are monitored, the display speed will be significantly reduced.
Therefore, monitor the link relay (B) and link register (W) that are allocated by the network parameter.

Monitoring devices of other networks (Bus connection, CPU direct connection, computer link
connection)
• Be sure to designate the routing parameter to the PLC CPU of the connected station.
• If another network is monitored, the display speed of object etc. will be significantly reduced.
