Profilix 4 Lost Data for Graphs

[KStatefan]

My P4 stopped saving data for the graphs. The last data is from 11/9/2025 at 2:31 AM I did not change anything at that time but I did change the time over the weekend but not a 2:31 AM. I had it set to change automatically in 7 days but had not changed yet. I have my second P4 set the same way and it is working correctly.

Any idea where to look?

Hello,

Please open a support ticket.

Thanks,

I submitted a ticket but it might be fixed now. I had orginally changed the "Automatic setting" to none but this morning changed it to DCF like my second P4 was and now it looks like is is recording.

The DST functionality of these controllers continues to be a problem for me. I gave up and simply turned it off and deal with the timezone warning for 6 months of the year.

@KStatefan -- my chart data does not appear to be broken, though I don't use the chart often, I find it hard to read and insanely buggy (hiding and showing series breaks it) and would prefer a chart per sensor or multiple configurable charts, but that is not here or there.

@Gaël @Matthias Gross
Is this DST functionality something that we can talk about? At the very least having the ability to simply fully suppress all timezone warnings and notifications?

Posted this before, but here is what I do when the clocks change to get the correct time and clear the time not matching local time warning. I do not use the "Change from winter to summer time" check box. Takes a minute or less to complete these steps.

1. Set Automatic Setting to None (from NTP).
2. Set to PC-Time.
3. Set Time Zone. (I am on the east coast: Summer UTC-4, Winter UTC -5)
4. Save settings to controller.
5. Set Automatic Setting back to NTP.
6. Save settings to controller.
