Error description 140-0046

Error message

Data change without effect

Cause of error

More than one MP subfile is loaded, or parameters were changed by a PLC module.
An attempt was made to edit data, but the changes have no effect during control operation because they are covered over by MP subfiles or PLC changes.

Error correction

Check the active data in the 'effective data' data record. If they do not have the desired values:
- Reload the MP subfile in which the changes were made
- Unload other MP subfiles
- Edit the data in the 'temporary files' data record
