ASCII Protocol
When you configure the serial port for User mode and the ASCII protocol, you
can use it to do the following:
•
Read ASCII characters from a weigh scale module or barcode reader.
•
Send and receive messages from an ASCII-triggered device, such as a
MessageView™ terminal.
After you configure the controller for use with the ASCII protocol, program the
controller by using the ASCII instructions. Reference the Logix5000 Controllers
General Instruction Reference Manual, publicat
for
information about the ASCII instructions.
