Read/Write Raw/ASCII Serial Devices
Read/write raw/ASCII serial devices use the Serial Device Configuration page to:
•
Allow connections between a serial device, such as a barcode scanner or RFID reader, and a PLC and/or
application(s).
•
Provide an optional filtering mechanism for string, RFID, and barcode data.
Note: The PLC and application(s) can both communicate to the serial device, but they cannot communicate
directly to each other.
