This example demonstrates a program to receive data from a barcode reader with a RS232C port using the user communi-
cation RXD1 (receive) instruction.
System Setup
Description of Operation
A barcode reader is used to scan barcodes of 8 numerical digits. The scanned data is sent to the OpenNet Controller
through the RS232C port 1 and stored to data registers. The upper 8 digits of the data are stored to data register D20 and
the lower 8 digits are stored to data register D21.
Programming Special Data Register
