Chapter 1
Communicating with an ASCII device
You can exchange ASCII data with a device through the serial port of the
controller. For example, you can use the serial port to:
Read ASCII characters from a weigh scale module or bar code reader.
Send and receive messages from an ASCII triggered device, such as a
MessageView terminal.
Firmware revision 3.1 and later of the 1756-EWEB EtherNet/IP Web Server
module supports the controller serial port and a socket interface that lets
Logix5000 controllers exchange ASCII data using TCP or UDP socket services.
