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.
