The Hot standby unlocated data's exchange list contains invalid items. The project must be rebuild all
Hi All,
I have control expert V15.3 and the hot standby M580S PLC (SV 4.21)
The issue is Control expert (V15.3) showing some error while building the application changes in online mode for HSBY M580S PLC and process failed with error.
Below are the errors for configuration:
- hsby list: Task [MAST] expected number [673], real number [674]
- The Hot standby unlocated data's exchange list contains invalid items. The project must be rebuild all
- Configuration binary generation error.
Would installing the newly released version 16.4 resolve this error, or is there any available hotfix for it?
