Serial Communication on 1756-L6x Controllers

Modbus Support

To use ControlLogix controllers with the Modbus protocol, establish a serial port
connection and execute a ladder-logic routine.

Two controller projects specific to the Modbus network are available as sample
programs within the Logix Designer application:

•

ModbusMaster.ACD

•

ModbusSlave.ACD

For information about using these sample programs, see the Using Logix5000
Controllers as Masters or Slaves on Modbus Application Solution, publication
