I have 2 PM810 which are not permanently powered and they sometimes lose their configuration (communication parameters, language etc..) at restart.
Do you have history of such a phenomenon or any clue why it could happen?
Are the settings stored in flash memory or through battery system? if so, is there a way to check battery status/capacity?
nothing so far. As they do not have the latest FW revision (they have n-1 version), I am considering suggesting them to upgrade and see...
Any other idea on your side?
The PM810 has no internal battery. It will definitely lose the clock, but I never experienced it losing the program.
We have received your query, there is a technical case registered already and escalated to L4.
You will be constantly notified of what is going on by my colleague who handles the case.
thanks for your feedback.
I have now a case open with Power Technical Support.
I will post the outcome of this issue when it is solved.
We have encountered configuration loss after restart in commissioning stage of several projects in Taiwan as well.
Please also inform me if there's a fix.
the case was closed because I could not provide sufficient information on what was happening.
You should contact Power Technical Support and open a case also, that may help deeper investigations if we are several users facing this issue,
For each device which have encoutered this issue, could you please report the values of modbus registers 8927, 8928 and 8929?
