Unexplained "ON" commands sent to many modules

[ES1400]

In general my 994I and 30 + modules have been functioning correctly for many months. However; this is the second time I encountered "ON" commands sent to at least half on the modules with NO logical reason, nothing in the LOG file to trace back. I'm starting to think the PLM is sending these ON commands in error. I do know the system was idle (meaning nothing much happing for several minutes) at about the time these "ON" commands occurred, and NOT responding to devices like motion detectors.  

 

The PLM is about 20 months old and "seems" to be functioning correctly.

 

 Has anybody experience unexplained commands or anything similar?
