Expression Syntax Error

Looking for some help creating this expresion in an SFC chart.

This is what I have, but doesn’t seem to work and I don’t get any errors.

{chart.tagPath}+ "plc_ValidateTrigger" = true

“{chart.tagPath}” is a chart parameter.


You are comparing a string to the value true, which will return false. A string does not equal the value true, so false is returned.

What are you trying to do?

Are you trying to return the value of the tag? If that is the case then do it like this:

tag({chart.tagPath}+ "plc_ValidateTrigger") = true

Or like this:

tag({chart.tagPath}+ "plc_ValidateTrigger")

Thanks! that worked. Yes I was wanting the value of the tag.
