I have some problem with tags that are interpolating during the motor direct start ramp. I tried changing the attributes of compdev and excdev, but this did not work.
Can anybody help me with that?
You could try to convert the tag to stepped.
Make sure the update frequency (scan class / polling rate, excmax, compmax) is high enough to keep the resulting data 'analog-like'.
If you would like to disable interpolation, Roger has the correct answer - turn on the Step attribute for the tag. In SMT this can be found under the Archive tab in Point Builder.
