423
Insufficient network table
information. Add station no.
The station number set in the project data and the station number set in
the switching station No. device do not exist in the Ethernet setting of GT
Designer3.
• Add the station number set in the project data to the Ethernet setting of
GT Designer3.
• When using the station No. switching function, check the data of the
switching station No. device.
When the station number specified in the switching station No. device
is not set in the Ethernet setting, add the station number to the
Ethernet setting.
When the station number does not exist in the system, change the data
of the switching station No. device.
(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.)
424
Same sta. on GOT & project
data. Review communication
parameter.
The station number set in the GOT's utility is the same as the station
number set in the Ethernet setting of GT Designer3 or GT Designer2 (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.
425
A duplicate IP address has been
detected. Confirm the setting. The IP address of the GOT is the same as that of the controller.
Change the IP address of the GOT or the controller.
448
PLC cannot handle as
requested. Correct devices.
A device outside the range of PLC file registers and the buffer memory
was specified.
Correct the monitor device by setting file register of the PLC CPU.
449
Dedicated device is out of range.
Confirm device range. Set the address for the special function module in the GOT monitor
available range. Set the device in the GOT monitor available range.
450
Path has changed or timeout
occurred in redundant system.
The path has been switched or timeout occurred in the redundant system.
• Check the PLC CPU to know if the path has been switched.
• Check the cable connection status 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 times for general data/Data update batch
processing.
451
Q redundant system settings and
current config. do not match. Change the Q redundant setting in accordance with the actual Q
redundant CPU system.
460 Communication unit error
• Reset the power of the GOT.
• Replace the unit.
