ControlNet-to-FOUNDATION Fieldbus H1
Linking Device
Catalog No. 1788-CN2FF
Product Overview The ControlNet-to-Fieldbus linking device connects a ControlNet™
network with one or more FOUNDATION Fieldbus H1 (Fieldbus) networks.
Each H1 network consists of multiple Fieldbus devices. Each field device
has one or more function blocks. Each function block performs an
elementary control function such as analog input, analog output, discrete
input, or discrete output. The ControlNet network consists of controllers,
such as PLC® processors, HMIs, drives, I/O devices, and so on.
The linking device has two broad functions, supporting the following:
•closed-loop control
•configuration and monitoring
Refer to the ControlNet-to-FOUNDATION Fieldbus H1 Linking Device User
Manual, publication 1788-6.5.1, for detailed information about these
functions.
To the Installer Use this document as a guide when you install the ControlNet-to-Fieldbus
linking device.

Linking Device
Hardware Description
Figure 1 shows the components of the linking device.
Figure 1 ControlNet-to-FOUNDATION Fieldbus Linking Device
The linking device is designed to be mounted on a 35 mm DIN rail. It has
one ControlNet port with support for redundant media and a network access
port. The ControlNet status LEDs on the front of the linking device display
the current status of each of the redundant media channels. The rotary
switches are used to set the ControlNet network address. You can write the
network address in the space provided on front of the device.
The linking device has two separate Fieldbus ports. Next to each port is an
LED to display the current status of the port. The status LED indicates if the
device is powered on and operating properly. The power connections are
used to supply power to the linking device.

Software Description
Use the NI-FBUS Fieldbus Configurator to configure a Fieldbus network
and keep track of your configurations. The Configurator is an easy-to-use
graphical environment for creating Fieldbus linkages, loops, and schedules.
Figure 2 shows the Configurator Main window. For more information, refer
to the NI-FBUS Configurator User Manual, publication 1788-6.5.2.

Installing the Linking Device The linking device has a rugged, simple clip for mounting reliably on a
standard 35 mm DIN rail. Follow these steps to mount the linking device
onto a DIN rail.
1. Use a flat-bladed screwdriver to open the DIN rail clip to the unlocked
position.
2. Hook the lip on the rear of the linking device onto the top of a 35 mm
DIN rail and press the linking device down onto the DIN rail.
3. Slide the linking device to the desired position on the DIN rail. After it is
in position, push the rail snap into the locked position to lock it in place
on the DIN rail.

Removing the Linking Device To remove a linking device, unlock it from the DIN rail by placing a
screwdriver in the slot on the rail snap and opening the rail snap to the
unlocked position as shown in step 1 on page 6. Then lift the device off of
the rail.
Connecting Power An 11-30V dc power supply is required by each linking device. The linking
device filters and regulates this supplied power. The power connector is a
6-pin screw terminal connector. The pinout for the power connector is
shown in Figure 3.
Figure 3 Power Connector Pinout
Connect the primary power supply to the center V and C pair. An optional
backup power supply may be connected to the left V and C pair. The right V
and C pair may be used to chain the primary power supply to other devices.
All three terminals labeled C are connected in the linking device. The right
two V terminals are connected in the linking device. These connections are
indicated on the power connector by the lines over the V and C terminals.

Connecting to
the ControlNet Network
There are two types of ControlNet connectors on the linking device. The
BNC connectors are for direct connection to a ControlNet network through
a tap. The BNC connectors must be used to connect the linking device to the
ControlNet network. The RJ-45 connector is a network access port (NAP).
This port is only for temporary connections to a ControlNet network.
Figure 4 shows an example of a typical network connection.
Figure 4 Typical Linking Device Connections to a ControlNet Network
Important:Do not connect the linking device to more than one ControlNet
network at a time. Attempting to connect to a second network
will cause the linking device to operate erratically.

Setting the
ControlNet Network Address
Valid ControlNet network addresses are 1-99. Network address zero is
reserved. Switch 1 controls the most significant decimal digit (the tens).
Switch 2 controls the least significant decimal digit (the ones). Figure 7
shows the location of the network address switches and an example of
switch settings for a network address of 15.
