SEL measurements do not get archived

Hi!

I am trying to use openPDC to extract phasors from a SEL 487-E. I can see the values in openPDC Manager->Graph Measurements but when I use the REST web service to get the data, no data is there. I extract data at the same time in the same conditions from an Arbiter 1133A Power Sentinel and everything works fine for it.

Any help would be highly appreciated!

To be more specific, I have an Arbiter in a different network => works fine.
I have another Arbiter and a SEL in the same network (different from the first) => I can graph the values but the values are marked with NaN values.

All 3 PMUs send data to the same openPDC.

Why are they marked with NaN values although I can graph them and why aren't they archived for the 2 PMUs residing in the same network. Has anybody encountered this sort of problem ?

Thank you!

Ok, so SEL data is not getting archived by the historian for whatever reason.
