I am using the Industrial Connectivity with PLC Rockwell and I have some TAGs type REAL/FLOAT which are working. when I try to add a TAG type String, i got the below error

Unable to read tag. Controller tag data type unknown. Tag deactivated. | Tag address = 'HMI.FORMATHND.PRODUCINGNAME', Data type = 0XFCE.

can someone help with that?

What does the tag address look like?

Strings in AB have 2 parts, DATA and LEN. I expect you have to append '.Data' to the strings tagname

Hello, 

see below. yes it includes Length and data. I want to see the de text. if i use Data or len then i see just a value. how can i transform this to the text (string)?

[SlidingDownhill · Accepted solution]

add the number of characters you want to the end of that string, i.e.  .DATA/20  or  .DATA/82
