I have some tags( float 32 type) that would like to see step function turned ON. By doing this how does it affect my exception & deviation testing. Will the data be not reliable enough?
The live document for PI Server provides some information regarding the Step attribute for tag configurations:
From the link, it mentions that the step attribute setting affects both display and compression. When step is enabled for the tag, compression testing is not used. Instead, exception calculation is applied using the CompDev value. The compression maximum and minimum still works the same as for points with step disabled.
I don't think this affects the reliability of the data. Is there any specific concerns on how step affects the reliability of the data for the tags?
