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.
31154
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
ÿ
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.

Install 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
WARNING
Do not install or remove the daughtercard while the host is
under power.
Inserting or removing the module while host power is on may
cause an electrical arc. This could cause an explosion in
hazardous location installations. Be sure that power is removed
or the area is nonhazardous before proceeding.

Connect the Card to the Netwo rk
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 fiber cable such as
one listed below:
• 1786-FS10 (10m cable assembly)
• 1786-FS20 (20m cable assembly)
• 1786-FS60 (60m cable assembly)
• 1786-FS100 (100m cable assembly)
• 1786-FS200 (200m cable assembly)
• 1786-FS300 (300m cable assembly)
For more fiber cable options, refer to the ControlNet Fiber Media Planning and
Installation Guide, publication CNET-IN001A-EN-P.

IMPORTANT
The zipcord uses a duplex cable. Duplex cables use a single cable that contains two
separate fibers, one for transmit and one for receive.
To prevent inadvertent reversal of the trunk cable connections
(resulting in incorrect status displays), check the drop cable for a
label indicating the attached cable before you make your
connection.
Publication 1788-IN005A-EN-P - March 2001

To wire the module:
• Hold down the latch and insert the Channel A zipcord connector into the
duplex socket until the pins and latch lock into place (see the illustration
below).
Make sure you insert the blue pin (receive) of the z ipcord connector into the
left Rx and the black pin (transmit) into the right Tx socket.

It is not necessary to install nodes on coax segments. If you are
only using the repeaters to extend, then install a 75-Ω terminator

adapter (1786-RPA). This should be done t o al l repeaters that are
not connected to coax segments.

When you connect the daughtercard to a ControlNet network, you should also refer
to the ControlNet Fiber Media Planning and Installation Guide, publication
CNET-IN001A-EN-P.
See page 13 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
Use the following wiring diagram to connect the programming terminal to the
network using a 1786-CP cable.

Any ControlNet
interface card
1786-CP cable

The 1786-CP cable can be plugged into any ControlNet product’s NAP (Network Access Port) to provide
programming capability on the ControlNet network. A programming terminal connected through this
cable is counted as a node and must have a unique address.
ATTENTION
ÿ
Use the 1786-CP cable when you connect a programming
terminal to the network through the NAP port; using another
cable could result in possible network failures or product
damage.

IMPORTANT
If you connect or disconnect the ControlNet NAP 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. Be sure that power is
removed or the area is nonhazardous before proceeding.
The NAP is only available on the 1788-CNF. It is not available on
the 1788-CNFR.

Troubleshoot with the Status Indicators
Status indicators provide information about the card and the network when you are
connected via the fiber connectors. The following definitions and tables outline the
possible states, explains what each state means to you, and indicates 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.
