TagRead() in text display functions does not work.

Brandon over 5 years ago

I cannot get TagRead to return a value in an text object with numeric display.

Consider the following example:

INT FUNCTION IsGreater(sTag)

RETURN StrToInt(TagRead(sTag)) > 100

END

If this function is placed in a text object the function displays nothing. If I run this function in function Message() I receive a result.

In Citect SCADA 2018 we introduced a non-blocking function, TagGetValue(). See help here: https://gcsresource.aveva.com/Citect/WebHelp/citect2018R2/Content/WhatsNew_IndirectTagValueLookups.htm
