I've added some health points to better monitor my OPC-DA interface. However, scan class 0 is the only one I get data for. I've created "scan class IO rate", "scan class point count", "scan class scans skipped", "scan class scan time" for each scan class but I only get results for the "sc0" class (whatever that is). Am I misinterpreting the manuals description of what these tags are for? all my tags are set to "advise", so I can only think that this is what the "sc0" scan class is for.
Can someone just clarify that I'm not going mad, and that there is a reasonable explanation for what I am seeing. Screen shot below (if not too cramped), might explain things better.
