About the Fieldbus Linking Device
The FOUNDATION Fieldbus Linking Device bridges from the Ethernet
network to H1 networks. It accepts either High-speed Ethernet (HSE) or
EtherNet/IP messages and converts them to the H1 protocol. By supporting
H1, HSE, and EtherNet/IP protocols, the linking device is capable of
providing bridging capability of Rockwell Automation products and
FOUNDATION Fieldbus products on the Ethernet network to products on H1
links.

Install the Linking Device
Install your linking device by using the instructions on the following pages.
Mount the Linking Device
Most applications require installation in an industrial enclosure (Pollution
Degree 2) to reduce the effects of electrical interference (Over Voltage
Category II) and environmental exposure. Locate your linking device as far as
possible from power lines, load lines, and other sources of electrical noise
such as hard-contact switches, relays, and AC motor drives. For more
information on proper grounding guidelines, see the Industrial Automation
Wiring and Grounding Guidelines, publication 1770-4.1.
ATTENTION
•We do not recommend vertical mounting due to heat build-up
considerations.
•Be careful of metal chips when drilling mounting holes for your linking
device or other equipment within the enclosure or panel. Drilled
fragments that fall into the unit could cause damage.

Publication 1757-IN021E-EN-P - August 2009
Mount on a DIN Rail
The linking device DIN-rail latch locks in the open position so that the
linking device can be easily attached to or removed from the DIN rail. The
maximum extension of the latch is 15 mm (0.67 in.) in the open position. You
need a screwdriver to remove the linking device. The linking device can be
mounted to 35 x 7.5 or 35 x 15 DIN rails (EN 50 022). See page 10 for
DIN-rail mounting dimensions.
Do these steps to install your linking device on the DIN rail.
1. Verify that the placement of the linking device on the DIN rail allows
for 50 mm (2 in.) of space on all sides for adequate ventilation.
2. Hook the top slot over the DIN rail.
ATTENTION
This product is grounded through the DIN rail to chassis ground. Use zinc
plated yellow-chromate steel DIN rail to assure proper grounding. The use of
other DIN rail materials (for example, aluminum or plastic) that can corrode,
oxidize, or are poor conductors can result in improper or intermittent
grounding. Secure DIN rail to the mounting surface approximately every
200 mm (7.8 in.) and use end-anchors appropriately.

Wire the Linking Device
Wire your linking device by using these instructions.
Wire Requirements
The FOUNDATION Fieldbus recommendation for the cable connecting
fieldbus devices is 0.8 mm2(18 AWG) shielded, twisted-pair wire. It is
important to calculate how the planned topology for your fieldbus segment,
selected wiring, supplied power, and intended mix of fieldbus devices may
impact the overall performance of a fieldbus network.
For further details, see:
•theF
OUNDATION Fieldbus specifications at http://www.fieldbus.org,
publication AG-140
• the Fieldbus Solutions for Rockwell Automation’s Integrated
Architecture User Manual, publication 1757-UM006, for a condensed
overview of fieldbus wiring considerations.
WARNING
•If you connect or disconnect wiring while the field-side 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.
•When you change switch settings while power is on, an electrical arc can
occur. This could cause an explosion in hazardous location installations.

Ethernet Connection
Connect your Ethernet cable to the Ethernet port on the underside of the
linking device. The factory default for the linking device is Dynamic Host
Configuration Protocol (DHCP) for initial configuration.
H1 Terminal Block
The linking device provides two parallel terminals on each H1 network. Use
one to connect to your fieldbus devices and use the other for short-term
connection of diagnostic devices.
Perform the following steps to connect the H1 cables.
1. Strip about 5…7 mm (0.2…0.28 in.) of the insulation at the ends of
the cable leads.
2. Insert the stripped cable end into the RTB, following the layout on
page 13, and tighten the screw.
WARNING
If you connect or disconnect the communication 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
WARNING
When you connect or disconnect the removable terminal block (RTB) with
field-side power applied, 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.
ATTENTION
Be careful when stripping wires. Wire fragments that fall into the linking
device could cause damage.
IMPORTANT
The H1 terminal plugs are keyed so they fit only into the corresponding
socket. Be certain that you are connecting the cables to the correct plugs.

Foundation Fieldbus Linking Device 13
Publication 1757-IN021E-EN-P - August 2009
3. Complete step 1 and step 2 for all H1 cables.
4. Insert the RTB into the corresponding socket.

Configure the Linking Device
The following instructions describe how to configure and set up network
parameters for your linking device.
Assign an IP Address
The Rockwell Automation BOOTP/DHCP Server (BOOTP) is a standalone
program that combines the functionality of standard BOOTP software with
DHCP software. The linking device is shipped with DHCP enabled.
To configure the linking device by using BOOTP, perform the
following steps.
1. Choose Start > Programs > Rockwell Software > BOOTP-DHCP
Server 2.3.2 Standalone > BOOTP-DHCP Server 2.3.2 Standalone.
BOOTP opens and the linking device sends a request.
2. Verify that the linking device is the correct device by matching the
MAC address with the MAC address found on the label of the linking
device (under the barcode).

Foundation Fieldbus Linking Device 15
Publication 1757-IN021E-EN-P - August 2009
3. Double-click the request.
A New Entry dialog box opens.
4. Type the IP address for the linking device.
5. Click OK.
The device is added to the Relation List at the bottom of the
BOOTP/DHCP Server window.
6. To permanently assign this configuration to the linking device, select
the device and click Disable BOOTP/DHCP.
When you cycle power to the linking device, it uses the configuration
you assigned and does not issue a DHCP request.
