That manual did not help me.
I need bind a tag (type: string) because I want show in my dashboard one operator name that is into my PLC. I was able of bind others tag's type (e.g float, interger) but type string I could not.
@einsfele What version of ThingWorx Industrial Connectivity are you using?
Are you trying to read Strings as an array?
Please note that you cannot read Strings as an array, then address an individual element. Strings can only be read one at a time as in the Allen-Bradley Logix addressing scheme a string, by definition, is a 'Null terminated character array'. It is not possible to read an array of arrays by the driver.
Previously attached manual's link was broken hence attaching it again:
