Have a tag with data type set as string.
Just encounter a phenomenon/behavior using Tag Events - Value Changed. When the data string sent to this tag is a chuck of data separated by delimiter. However every time the data received by the tag, the only changes is in small delta, the tag Value Change is unable to recognize as Value Change and thus, the script written in there would not be executed.
Had tried changing its Metadata - format string to more decimal places such as #,##0.#######
But it still wont work - still unable to detect the minor changes and the script inside Value Change will not execute.
Wonder if anyone encounter the same ?
Appreciate any advice or comments
