Ignore negative values from OPC DA Tags

Question asked by VasanthakumarR Champion on Jun 19, 2019



We want to ignore the negative values from the input tag during the totalizer calculation.

We are aware of the approaches in analysis and also using the Totalizer tag. But we want to do it the PI Tag configuration level. The reason behind this is to avoid creating multiple analysis and tags in order to ignore negative values.

Input tag getting via OPC DA interface from the source OPC server. Can someone let us know the possibilities to achieve this in the tag configuration level?
