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.

switching station No. device.
When the station number specified in the switching station No. device
is not set in the Ethernet setting, add the
Ethernet setting.
When the station number does not exist in the system, change the data
