Hello,

I would like to ask for your help, again. 😄

I created the following Union:

TYPE CognexReader :
UNION
    ResultData : ARRAY[0..4] OF WORD;
    ResultString : STRING(10);
END_UNION
END_TYPE

I instantiated it.

PROGRAM PLC_PRG
VAR
    Result : CognexReader;
END_VAR

It works fine but currently I have to map each I/O to the element of the array.
I am wondering if there is a better approach b/c currently I have some 120 WORD to link to the union.

I cannot link the whole ARRAY as the result data starts from index 5.

Thanks for your help in advance.

I really appreciate.

Best Regards!

What about linking the whole array to another array starting at index 5?

Or can you put Application.PLC_PRG.Result.ResultData[5..120] if you only want to use index's 5-120?

Hm maybe I didn't get... 🤔

I use Union in order to have the STRING representation of ARRAY[0..4] OF WORD.

So somehow I need to map the PLC Output's 5..120 indexes to UNION CognexReader.
