I am configuring notifications with group alerts. With the search criteria being expressions (which I assumed was a string since the db default is a varchar) it will only let me enter numeric expressions otherwise I get parsing Sytanx errors back:
Example: Syntax Error on Token: ‘End of Expression’ (Line 0, Char 0)
Questions:
- Can I not use string expressions?
- When using default (Ignition generated tabel) Alert_Log what column is being searched for the expression?
- When configuring the tags alert properties, what is the suggested field to modify for expression (Display Path) - understanding this could be based on the answer to number 2 and subject to how end user wants to see alerts.
Thanks for any help
