Hello everyone!


Using PI compressed data within PI Datalink in Excel I came across the "If then else" function used as a filter expression. I can see what the filter expressions (Filter 1, 2, 3 and 4) are doing, but I cannot find a good explanation how it works behind the scene. It seems like putting "0" into "then" or "else" is the key here. Can someone point me to an explanation?
