The station number set in the GOT's utility is the same as the station number set in
the Ethernet setting of GT Designer3 (the station number of the PLC side Ethernet
module) or in the project data.
Check the following contents so that the multiple station numbers should not be the
same.
• Check the GOT's station number in the GOT's utility.
• Check the station number set in the project data.
• Check the station number set in the Ethernet setting.
(Set the station number so that it becomes the same as the station number of
the PLC side Ethernet module set in the parameter setting of GX Developer.)
• When using the station No. switching function, check the data of the switching
station No. device.
The GOT has the same IP address as another device.
Change the IP address of the GOT or the device.
The wireless LAN communication unit is not installed on the side interface.
Check that the unit is installed properly.
Check the setting for an accessible access point, and the wireless LAN connection
setting.
After configuring the wireless LAN connection setting, enable the wireless LAN

and the PLC CPU status.
• This error may occur when the load of the PLC CPU becomes heavier when
accessing other stations. In such a case, transfer the data of the other stations to
the host station PLC CPU and monitor them at the host.
• Perform one of the following operations if the PLC scanning time is long: COM
instruction/Extension of END processing/Setting of the number of processing
