I have barcode data in a string data table in my SLC5/05 from a laser engraver (ST) and I need to compare it to barcode data in a ASCII data table (A) from a Cognex camera.

I tried to bring the camera data directly into a ST register but no luck (all the Cognex examples show ascii registers).

I would like to move the 15 characters (could be changed to 16) from the ascii table to the string table so I can compare the two. Any suggestions?

since the slc are 16 bit processor & don't have sint data type it hold the data in pairs
