ControlNet Daughtercard

Catalog Number 1788-CNF, -CNFR

This document describes how to configure the ControlNet™ 1788-CNF and -CNFR daughtercards. In this document, we use the term ‘the card’ to refer to both daughtercards collectively. When one card is different from the other, we refer to the daughtercard by name.

About the Daughtercards

The network daughtercard architecture defines a common hardware and software interface that several different network interface cards will support. This lets products that have been designed to support the network daughtercard option to support several different Rockwell Automation networks.

About the C ontrolNet Daughtercard

Y ou can install the 1788 -CNF or -CNFR ControlNet daughtercard in any host device that supports the ControlNet daughtercard1.

Every ControlNet network requires at least one module that is able to store parameters and configure the network with those parameters upon start-up. This module is called a ‘keeper’ since it keeps the network configuration.

Any 1788-CNF or -CNFR card can keep the network parameters at any legal node address (01 to 99). Multiple devices on any one network can act as the network keeper. Each device capable of being the network keeper acts to back up the current keeper. This backup function is automatic and requires no action on your part.

IMPORTANT

1. The host device must provide a suitable power source per the restrictions in the specifications table.

Publication 1788-IN005A-EN-P - March 2001

On the 1788-CNF or -CNFR card, the non-volatile keeper data is erased when a firmware update is performed.

How to Handle the Card

ATTENTION

Take these precautions to guard against ESD damage:

• Touch a grounded object to discharge any built-up static.

• Do not touch the connector or connector pins on the card.

• When not in use, store the card in the anti-static packaging in which it was

shipped.

The card uses CMOS technology, which is highly sensitive to electrostatic discharge (ESD). ESD may be present whenever you are handling the card. Handling the card without any ESD protection can cause internal circuit damage that may not be apparent during installation or initial use.

Set the Node Address

You must set two switch assemblies to configure the daughtercard with its unique network address. Figure 1 (next page) shows the location of the switches. These switches are read on powerup to establish the network address of the card.

Set the node address to a value between 1 and 99. For optimum throughput, assign addresses to your ControlNet nodes in a sequential order starting with 01.

Node address 00 is not a valid ControlNet address. You should only use node address 00 if the product that uses the ControlNet daughtercard has the ability to set the node address using the host device interface.

This feature is typically used on products that do not provide easy custom er access to the node address switches. If you set the node address switch to 00, it lets the host in which the daughtercard resides set the node address, rather than letting the daughtercard read the node address from the switch settings.
