I have a CP1L by Omron and a barcode reader by Honerwell. I want to activate the serial port 1, to connect it with the reader. The reader shoul read one of the 2 main barcodes. If the reader get the barcode 1, then it should read 3 times the barcode A and activate an output; but if it read the barcode 2, it should read 3 times the barcode B, and also activate an output. I want made my programm in ladder programation, How I can activate the serial port 1? How I set the the serial port 1 as an input to the function block RXDU? How works the FB RXDU? How I can set the codes? How I set the fb RXDU as an output?
