Issue
The outputs of three kitControl objects - Maximum, Minimum, and Average - will all go to Nan if any of its inputs are Nan.
Product Line
TAC IA Series
Environment
I/A Series G3 (Niagara) station
Cause
The internal logic of these blocks is set to pass Nan through if all inputs are not valid for comparison.
Resolution
There are two potential work-arounds:
- Pass the inputs through some intermediate logic to ensure that a Nan value is never passed to the Minimum, Maximum, or Average blocks. Null values are valid and will allow the internal logic of the block to proceed.
- Use the MinMaxAvg block instead. It is located in the kitControl > Util folder. The internal logic of this block will ignore Nan inputs.
