Tag history - Up to one week or 10 million data points of history can be stored locally. Pruning will automatically happen, and the historian is automatically enabled and not configurable.
Above mentioned document of ignition edge Version 7.9.2 says it has capability to hold upto 10 million data points. in latest version of 7.9.9 does the tag historian provide space to hold unlimited data points ? or does it still have any limitations?
