Communicating with
Other Controllers
and Communication
Devices
The ControlLogix system takes advantage of several networks to allow
communications with many different controllers and devices. The following table
lists which products the ControlLogix controller can communicate with over which
networks.

The Ethernet PLC-5 processor must be one of these:
series C, revision N.1 or later
series D, revision E.1 or later
series E, revision D.1 or later
†The 1785-ENET Ethernet communication interface module must be series A, revision D or later.
‡The PLC-5, SLC, and MicroLogix processors appear as I/O points to the Logix controller. Requires 1761-NET-DNI DeviceNet interface.
§Use a 1747-L55x controller with OS501 or greater.
♣
Use a 1747-L54x controller.
➤
The PLC-2 controller requires a 1785-KA module for DH+ communications.
a
The PLC-2 controller requires a 1771-KG module for serial (DF1) communications.

The PLC-3 controller requires a 1775-S5 module for DH+ communications.
™
The PLC-3 controller requires a 1775-KA module for serial (DF1) communications.

✶
Use the generic module configuration to configure the 1203-CN1 module and a CIP generic MSG instruction to communicate with the module.
†Use a CIP generic MSG instruction to communicate with the 1203-FM1 SCANport module on a DIN rail that is remote to the controller. The remote DIN rail also requires a 1794-ACN(R)15 ControlNet adapter module.
