112 Rockwell Automation Publication 1756-UM001O-EN-P - October 2014
Chapter 6 Serial Communication on 1756-L6x Controllers
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, publication 1756-RM003,
for
information about the ASCII instructions.
