SLC 500 Programmable Controllers and I/O Modules

DeviceNet connectivity for the SLC 500 is provided by the following interfaces:

1747-SDN DeviceNet Scanner Module

The 1747-SDN DeviceNet Scanner modules acts as an interface between DeviceNet devices and SLC

5/02 or higher processors. The scanner communicates over the DeviceNet network to:

• Read inputs and write outputs

• Download configuration data

• Monitor operational status

The scanner communicates with the SLC processor to exchange I/O data. Data includes device I/O data,

status information, and configuration data. A single scanner can communicate with up to 63 nodes. The

SLC system can support multiple scanners.

1761-NET-DNI DeviceNet Interface Device

The DNI takes the DF1 full-duplex commands, wraps them in the DeviceNet protocol and

sends them to the target DNI. The target DNI removes the DeviceNet information and

passes the DF1 command to the end device (Also acts as an interface for DF1 devices

to the DeviceNet network).

This capability works between controllers, between PCs and controllers, and for program

up/downloading. I/O and data messages are prioritized, which minimizes

I/O determinism problems typically encountered on networks that support I/O

and messaging simultaneously.

Features

• Mixes high-speed local control with distributed DeviceNet I/O

• Peer-to-peer messaging between MicroLogix, SLC 5/03, 5/04, 5/05, PLC-5s, PCs and other devices

• Programming and online monitoring over the Device Net network

•With a DNI connected to a modem, you can dial in to any other DNI-Controller combination

on DeviceNet
