Specified station access is
out of range. Confirm
station no.
1. Station numbers other than master/local station are
specified at the CC-Link connection (via G4).
2. A PLC CPU other than QCPU is accessed.
Confirm the station number of the project data.
407
Accessed other network.
Change network setting.
• When monitoring the same network as the GOT
The GOT accesses the other networks with the MELSEC-
NET/H, MELSECNET/10 (PLC to PLC network), or CC-Link
IE Controller Network connection.Confirm the network
number of the project data so as not to access to other
networks.
• When monitoring other networks
Reconfigure the [Routing Information Setting] of GT
Designer3 or GT Designer2 or the [Routing parameters] of
GX Developer.
• When the GT15-75J71LP23-Z/GT15-75J71BR13-Z is used
These models cannot monitor other networks.
• Confirm Network No. of the project data, in order for not
accessing other networks.
