OPC DA Collector - Data Transform - NoOutput
Hi,
I have an instrument that sends negative values when not in function (ex: -9999). I want to filter these values. The following OPC DA Data Transformation works fine: (x<0?(0):x) but instead of sending 0, I'd like to send nothing (NoOutput).
I do not see how to do that but the documentation seems to indicate that this is possible
Thanks

Thanks Steve,
I knew the Calc Server can do that but I have many, many tags like this. That would almost double the number of tags.
What about the OPC UA collector? I saw that it can transform values as well as Qualities? I am planining to replace my OPC DA collectors by OPC UA collectors.
Thanks again
