Some of our users have begun using Data Sets in ProcessBook displays that call the FindEQ function looking for a string tag to be equal to a given value like:
The quoted string is correct for a particular phase they are looking for in the unit. However, this tag is just a string tag, and not a Digital tag. The function appears to be generating many, many 'PIvalue Type is Not Allowed For This Call' message in the PI Message Log. Is this a legal way to use this function, or when comparing to a string must the tag be a Digital tag?
