This is due to a bug in the Xenta Server firmware, and happens if you have a menta application that uses other modbus values than the ones being logged.
If you open a graphic or the value columns the log works.


This issue will be fixed in 5.1.9.

5.1.8 hotfixes for Xenta 913 and Xenta 700 are available on request from PSS.
