Cause Solution
1) Supply the power supply to unit as per
specifications.
2) Check the address of the substitute reference
device and the device values on the PLC side.
Refer to <5.3 Troubleshooting Error Codes>.
Transfer base screen data.
1) Create and register screen content or specify the
correct screen number.
2) Create and register keyboard screen or specify
the correct keyboard number.
3) Transfer base screen data from GTWIN.
Delete part of the base screen data so that the
capacity doesn't exceed the total capacity.
Data capacity can be checked by going to [View
(V)]→[Memory Usage Conditions] on GTWIN menu
bar. When the data capacity is not over the limit,
invalid data could possibly be remaining in the GT.
When transferring data, do so after deleting the
screen.
1) Specify the correct screen number.
2) Check the start-up screen setting for the GT
configuration settings in GTWIN. Delete
unnecessary settings and re-transfer
configuration data.
3) Check the device content specified on the PLC
side in the first word of the basic communication
area. (Do not use the basic communication area
with ladder programs.)
