I'm trying to write "no data" as the output of an analysis template and failing miserably.
I'm trying to make this work:
if tagmax('COB','*-1h','*') > 0 then "no data" else 'NCI'
The calculation seems to work when > 0 is false but I get an error writing the system state when > 0 is true.
I've tried "no data", 'no data' and then ran out of ideas
Is there a better way to do this (I can't output zero for various reasons)?
I don't think I can use NoOutput as the tag will just retain its last value won't it?
