I have a customer that reads the QR code for the parts that are in process we pull out the information we need for the robots, message it to them and message the ASCII file to the last PLC in on the line there we display a QR code on the Cmore that they can scan into the computer. We also send the information directly to the inventory system thru FTP. We use Keyence SX1000 scanners, I open the TCP port on the scanner and stream in the ASCII to a long string (SL100). The SX1000's have been very good units. The first line we put them on was started in 2019 and have not had a failure. I have also used the serial hand held scanners from AD they work fine but we wanted to use ethernet not serial.
