i am using OpenHistorian to gather data from a PMU for quite some time now. We had been using this data in case of frenquency flactuations but a need has risen for data to be exported on a monthly basis from the said PMU.
On the OpenHistorian web manager > Trend/Export Measurements> Export Data i’ve been trying to lower the file size of the exported CSV by changing the Frame Rate.
Even by switching it to 1 frame per hour, the timestamps on the exported CSV are displayed on a second by second analysis, resulting into massive csv files.
Am i missing something that i need to configure regarding the frame rate? For example, if i want to extract data every 15minutes for an entire month what are the settings i need to modify to get that result?
