Communication Connections
Introduction This chapter describes how to communicate to your control system. The
method you use and cabling required to connect your controller depends on
what type of system you are employing. This chapter also describes how the
controller establishes communication with the appropriate network. Topics
include:
• supported communication protocols
• default communication configurations
• using communications toggle push button
• connecting to RS-232 port
• connecting to DH-485 network
• connecting to AIC+
• DeviceNet communications
MicroLogix 1200 controllers with the additional communications port
(1762-L24AWAR, 1762-L24BWAR, 1762-L24BXBR, 1762-L40AWAR,
1762-L40BWAR, 1762-L40BXBR) offer advanced communications options,
providing a clean, cost effective solution for applications requiring a network
connection and HMI.
The additional communications port (Programmer/HMI Port) enables two
communication devices to be connected to the controller simultaneously. For
example, it provides local connectivity of an operator interface or
programming terminal such as DF1 PanelView HMI, IBM-compatible
personal computer using RSLogix 500 programming software, or 1747-PSD
program storage device, and also allows the primary port (Channel 0) to be
connected to either a network, a modem, or an ASCII device such as a barcode
reader or weigh scale.
Supported Communication
Protocols MicroLogix 1200 controllers support the following communication protocols
from the primary RS-232 communication channel, Channel 0:
• DH-485
• DF1 Full-duplex
• DF1 Half-duplex
• DF1 Radio Modem
• Modbus Master and Slave
• ASCII
