Catalog Numbers 1788-CNC and 1788-CNCR

This document describes how to install and configure the ControlNet 1788-CNC and

-CNCR 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.

If you are connecting the card directly to a ControlNet network, you should also refer to these

publications:

•ControlNet Tap Installation Instructions, publication 1786-5.7

•ControlNet Coax Media Planning and Installation Guide, publication CNET-IN002

About the Daughtercards

The network daughtercard architecture defines a common

hardware and software interface that several different

network interface cards will support. This allows products

that have been designed to support the network

daughtercard option to support several different Rockwell

Automation networks.

About the ControlNet Daughtercard

You can install the 1788-CNC or -CNCR ControlNet daughtercard in any host device that

supports the ControlNet daughtercard.(1)

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-CNC or -CNCR 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.

WARNING •If you connect or disconnect the communications cable with

power applied to this module or any device on the network, an

electrical arc can occur. This could cause an explosion in

hazardous location installations.

•If you insert or remove the card while host power is on, an

electrical arc can occur. This could cause an explosion in

hazardous location installations.

•Be sure that power is removed or the area is nonhazardous

before proceeding.

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

IMPORTANT On the 1788-CNC or -CNCR card, the non-volatile keeper data is erased

when a firmware update is performed.

Setting the Node Address

You must set two switch assemblies to configure the daughtercard with its unique network

address. Figure 1 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 01 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 allow easy customer access to the node

address switches. If you set the node address switch to 00, it allows the host in which the

daughtercard resides to set the node address, rather than allowing the daughtercard to read

the node address from the switch settings.

Installing the Card

Due to wide variation in available host devices, we cannot provide specific installation

instructions in this document. For instructions on how to install the daughtercard in a host

device, refer to the user manual for the particular host device.

Daughtercard Performance

Due to wide variation in available host devices, we cannot provide specific performance

capabilities in this document. For information concerning host/daughtercard performance

characteristics, refer to the user manual for the particular host device.

Connecting the Card to the Network

After you have installed the card, you can connect it to the network. You must connect the

card to the network using an approved ControlNet tap:

•1786-TPR (T-tap right angle)

•1786-TPS (T-tap straight)

•1786-TPYR (Y-tap right angle)

•1786-TPYS (Y-tap straight)

We recommend the straight taps.

IMPORTANT Do not install or remove the daughtercard while the host is under power.

When you connect the daughtercard to a ControlNet network, you should also refer to this

documentation:

•ControlNet Coax Tap Installation Instructions, publication 1786-5.7

•ControlNet Coax Media Planning and Installation Guide, publication CNET-IN002

See page 14 for information about status indicators.

IMPORTANT If you use a non-redundant cable system, all ControlNet devices must be

on the same channel, we recommend channel A.

Connect to the Network Using a 1786-CP Cable

Follow this illustration to connect a programming terminal to the network using a 1786-CP

cable.

ATTENTION Use the 1786-CP cable when you connect a programming terminal to the

network through the network access port (NAP); using another cable

could result in possible network failures or product damage.

The NAP port is for temporary local programming purposes only and not

intended for permanent connection.

capability on the ControlNet network. A programming terminal connected through this cable is

counted as a node and must have a unique address.
