Hi,
most likely you'll have to look at NXSL extensions, data collection related functions are in src/server/core/dc_nxsl.cpp. Look for F_GetDCIValues - it is implementation of getting history for single value DCIs, and GetDCIValueImpl - it will give you idea how to return table value as NXSL object. Then you will need code to unpack table values. You can take a look at src/server/core/session.cpp, method ClientSession::getCollectedDataFromDB - you will be interested in code part around call Table::createFromPackedXML.
Best regards,
Victor
