Thanks, I'm going to try it!

So it's currently mapped to an array of BYTES? Can you create a UNION?

TYPE sBytesString :
UNION
    AsBytes: ARRAY[0..127] OF BYTE;
    AsString: STRING(128);
END_UNION
END_TYPE

Map it to the bytes, read it in the STRING!

Thanks, that's what I thought initially.
The point is that I can't select a String type variable. See the attached image

My guess is that's a STRING, not an INT type.

Hi there,

I have a Keyence bar code reader connected to my plc through Ethernet/IP.
The Bar code is 20 digits long (like 30100790020493036016), the scanner reads it correctly (I can verify that through the keyence software) but when it sends it through ETH/IP, it doesn't fit into a 64 bit variable and it trunks the data.(I've tried ULINT and LWord without success).
When I loaded the EDS file, the read variable was defined as a byte with 128 bits length, which is quite strange for me. (see attached picture)
How do I manage this variable?
Thanks!
