I need to build a copro program to recieve data from a bar code scanner via rs232 to the copro. Where does this data go and how do i send it to the PLC?

Typically you input the bar code scanner data into a string variable in the CoProcessor using the INPUT statement. Then you parse the data out of the string that you are interested in (using MID$ and VAL typically) and write it to V-memory in the PLC using the BMOVE or S06_, S205_, S405_ depending on which CoProcessor you are using.
There are some examples showing how to input serial data to a string, parse numeric data from the string, and write numeric data to the PLC at www.facts-eng.com (select 'BASIC Examples ' then 'serial Communication Examples ').
