You will need to set the port function in the PLC setup area. Take a look at the TXD instruction to send the data. Also make sure you understand the pin out of the Omron 9 pin port. It is NOT a standard pin out. Hope this will help.

Check out the sample programs from JA... although written for older type PLC;s the substance is nearly the same... http://forums.mrplc.com/index.php?autocom=downloads&showfile=288
