Serial Network 

The SLC 5/03, SLC 5/04, and SLC 5/05 processors have a serial port which is

configurable for RS-232 compatible serial communication. Use the serial port to connect

to devices that:

• communicate using DF1 protocol, such as modems, communication modules,

programming workstations, or other Encompass partner devices.

• communicate using DH-485 protocol.

• send and receive ASCII characters, such as ASCII terminals, bar code readers, and printers.

When configured for system mode, the serial port supports DF1 protocol. Use system

mode to communicate with other devices on the serial link. You can select the following

DF1 modes:

• DF1 full-duplex: provides communication between an SLC 500 controller and other

• DF1 compatible devices. In point-to-point mode, the SLC 500 controller uses

DF1 full-duplex protocol.

• DF1 half-duplex master: polls and transmits messages between the master and

each remote node. In master mode, the SLC 500 controller uses DF1 half-duplex polled protocol.

• DF1 half-duplex slave: uses the controller as a slave station in a master/slave serial network. 

In slave mode, the SLC 500 controller uses DF1 half-duplex protocol.

DF1 radio modem: a hybrid between DF1 full-duplex and DF1 half-duplex, 

this protocol is optimized for use with radio modem networks.

Selecting a ControlLogix System

The ControlLogix system architecture provides sequential, process, and

motion control together with communications and state-of-the-art I/O in a

small, cost-competitive package. The system is modular, so you can design,

build, and modify it efficiently - with significant savings in training and engineering.

A ControlLogix system can be anything from a simple chassis to a highly-distributed

system consisting of multiple chassis and networks working together.

A simple ControlLogix system consists of a stand-alone controller and I/O modules in a single chassis.

Or you can use the ControlLogix system as a gateway. Include the

communication modules you need for connectivity to other networks. For

this use, a controller is not required. The ControlLogix Gateway integrates

into existing PLC-based systems so that users with existing networks can

send or receive messages to or from other networks.

For a more robust system, use:

• multiple controllers in a single chassis

• multiple controllers joined across networks

• I/O in multiple platforms that is distributed in many locations and

connected over multiple I/O links
