ATTENTION
Environment and Enclosure
This equipment is intended for use in a Pollution Degree 2 industrial
environment, in overvoltage Category II applications (as defined in IEC
publication 60664-1), at altitudes up to 2000 meters without derating.
This equipment is considered Group 1, Class A industrial equipment
according to IEC/CISPR Publication 11. Without appropriate
precautions, there may be potential difficulties ensuring electromagnetic
compatibility in other environments due to conducted as well as radiated
disturbance.
This equipment is supplied as “open type” equipment. It must be
mounted within an enclosure that is suitably designed for those specific
environmental conditions that will be present and appropriately designed
to prevent personal injury resulting from accessibility to live parts. The
interior of the enclosure must be accessible only by the use of a tool.
Subsequent sections of this publication may contain additional
information regarding specific enclosure type ratings that are required to
comply with certain product safety certifications.
NOTE: See NEMA Standards publication 250 and IEC publication
60529, as applicable, for explanations of the degrees of protection
provided by different types of enclosure. Also, see the appropriate
sections in this publication, as well as the Allen-Bradley publication
1770-4.1 (“Industrial Automation Wiring and Grounding Guidelines”),
for additional installation requirements pertaining to this equipment.
ATTENTION
Preventing Electrostatic Discharge
This equipment is sensitive to electrostatic discharge, which can cause
internal damage and affect normal operation. Follow these guidelines
when you handle this equipment:
• Touch a grounded object to discharge potential static.
• Wear an approved grounding wriststrap.
• Do not touch connectors or pins on component boards.
• Do not touch circuit components inside the equipment.
• If available, use a static-safe workstation.
• When not in use, store the equipment in appropriate static-safe
packaging.

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.
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.
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.
IMPORTANT
(1)
The host device must provide a suitable power source per the restrictions in the specifications table.
Publication 1788-IN002C-EN-P - April 2004
On the 1788-CNC or -CNCR card, the non-volatile keeper data is erased
when a firmware update is performed.

ControlNet Daughtercard 7
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.
IMPORTANT
Do not install or remove the daughtercard while the host is under power.
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.

Interpreting the Status Indicators
Status indicators provide information about the card and the network when you are
connected via the BNC connectors. Tables 1 and 2 on the following pages outline the
possible states, explain what each state means to you, and indicate what action you should
take, if any, to correct that state.
Definition of terms:
• steady - indicator is on continuously in the defined state.
• alternating - the two indicators alternate between the two defined states at the same
time (applies to both indicators when viewed together); the two indicators are always in
opposite states, out of phase.
• flashing - the indicator alternates between the two defined states (applies to each
indicator viewed independent of the other); if both indicators are flashing, they flash
together, in phase.
IMPORTANT
Keep in mind that the Module Status indictor reflects the module state,
e.g., self-test, firmware update, normal operation but no connection
established, etc. The network status LEDs, A and B, reflect network
status. Remember that the host is able to engage in local messaging with
the card although it is detached from the network. Therefore, the Module
Status LED is flashing green if the host has successfully started the card.
Note, however, that until the host removes reset, all LEDs on the
daughtercard will remain off.
When you view the indicators, always view the Module Status indicator
first to determine the state of the daughtercard. This information may
help you to interpret the network status indicators. As a general practice,
view all three status indicators (Module Status, I/O Status, and Network
Status) together to gain a full understanding of the daughtercard’s status.
