1756-L6x Controller
Serial Port
The 1756-L6
x ControlLogix controllers have a built-in RS-232 port that can be
used in various serial-based applications. The potentialr serial communication
applications include the following:
•
DF1 modes (including broadcast message support)
•
DF1 radio modem
•
ASCII device communication

ControlLogix Chassis Serial Communication Options
You can use the serial port of the ControlLogix controller or use ProSoft modules
in the ControlLogix to achieve serial communication. Options specific to the
ControlLogix controller serial port are described in this chapter.
For more information about ProSoft modules that can be used to establish serial
communication, see the
website or go to
rowse available products.
