Hi all,
Is there a way for the OPC tags to show null rather than the last good value if the tags are bad or uncertain?
Based on the documentation, https://docs.inductiveautomation.com/display/DOC79/Understanding+Tags, bad and uncertain quality of tags will show last value. Also tested this, and got the same result. We need these tags to show null to indicated bad connection.
The only workaround I can think of is to create expressions tags with these expression: if({[.]tag.quality} != 192, null, {[.]tag}). But there might be a more efficient way to do this or a config that I’m missing.
Thanks a lot in advance!
