Other thing to note. I was told many years ago by a Rockwell Tech support person that if you are using the datalog it is the best idea to use a memory card to log the data to. It appears that early on in the PV+ lifetime there were some issues with how long the internal flash would last writing to it all the time with log data. Sometimes the internal flash would fail and the PanelView would no longer start up. Do not know if that could still be an issue, but memory cards are cheap compared to a PV+, so I have always followed that advice and so far have not had any problems from PV+ internal flash issues.
