Hi,
I need to use archived data with OpenHistorian 2 to test my application and I'm trying to use OpenPDC to playback historical data using archived frames in .d2 files.
Data are stored at 50 frames/s (50Hz system) and I want to playback 2 days (from 2018-01-13 00:00:00.000 to 2018-01-15 00:00:00.000) at the same frame rate.
I configured an output concentrated frame to a remote destination where I'm using PMUConnection tester to verify the correctness of playback.
With the parameter "SimulateTimestamp=True", I was expecting the output concentrated frame had the current date (February, 2nd) and time while instead I find the same date (January, 13) and time as the data in the .d2 file
With the parameter "AutoRepeat=True", I was expecting that, when reaching StopTimeConstraint timetag in archive file, playback restart from beginning. Configuring an interval of 10 seconds (StartTimeConstraint=2018-01-13 00:00:00.000; StopTimeConstraint=2018-01-13 00:00:10.000), the output frame stop after ten seconds.
To have an output frame rate of 50 Frame/s, I don't understand how to configure parameters PublicationInterval and ProcessingInterval. I supposed to configure PublicationInterval with the value 200000 (20 ms using 100-ns tick interval) and ProcessingInterval=20. With these values, I verified with PMUconnection tester a real frame rate of 32 Frame/s
Empirically, I verified a 50 Frame/s rate with these values:
PublicationInterval=312500
ProcessingInterval=20
Considering that PublicationInterval is a temporal interval, I thought that increasing this value, I would have obtained a slower frame rate and, on the contrary, decreasing this value, I would have obtained a faster frame rate. What I find is exactly the opposite, that this parameter and the frame speed are directly proportional.

I followed the steps listed at https://github.com/GridProtectionAlliance/openPDC/wiki/Getting-Data-From-the-openHistorian and I'm having a series of problems that I can not understand:
Any help would be really appreciated.
Thanks Daniele
