Before You Begin
Before you install the linking device, read and complete the following
sections.
WARNING
This product contains a ControlNet daughtercard (CAM) that is not intended for
removal. Any attempt to remove this CAM or to operate the CAM release
mechanism may cause irreparable damage. If you insert or remove the CAM
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.
Software Requirements
The following software is compatible with this revision of the linking device:
• RSFieldbus software, version 2.03 or later
• RSLinx Classic software, version 2.52 or later
• RSNetWorx for ControlNet software, version 8.00 or later
• Logix5000 Clock Update tool
• RSLogix 5000 programming software, version 16.03 or later
IMPORTANT
You must upgrade your linking device to RSLogix 5000 programming
software version 17 to program unscheduled Class 1 connections on the
ControlNet network. The upgrade is required if your system is running
RSLogix 5000 software version 16 without redundancy. If you are using
RSLogix 5000 software version 16 with redundancy, unscheduled Class 1
connections are not available on the ControlNet network.

Install the Linking Device
Install the linking device by using the following instructions.
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.

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 12
for DIN-rail mounting dimensions.
ATTENTION
Publication
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.

Wiring the Linking Device
To wire the linking device, complete the following sections.
Wire Requirements
The FOUNDATION Fieldbus recommendation for the cable connecting
fieldbus devices is Type A, 0.8 mm
2
(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 more information,
see the F
publication AG-140
OUNDATION Fieldbus specifications at http://www.fieldbus.org,
.
ControlNet Ports
WARNING
Connect your ControlNet cables to the ControlNet
ort on the side of the linking device. Two ports
(A and B) are provided for redundant media
ControlNet connections.
IMPORTANT
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.
44419
In a non-redundant system, connect the ControlNet cable to Port A on the
linking device. Port B is left unconnected.
In redundant system, all devices on a channel must be connected through
the same cable. That is, all channel A device ports connect to one cable; all
channel B device ports connect to the other cable.

1784-PCC cards.
he 1784-PCC card is not supported by RSFieldbus software,
ut RSFieldbus software can be used with the 1784-PCIC,
1784-PCICS, and 1784-U2CN cards to configure the
1757-FFLDC and FOUNDATION Fieldbus devices.
Connect the linking device to a communication card
ith a 1786-CP cable (1784-PCIC or 1784-PCICS card) or a
1784-PCC1 cable (1784-PCC card).
WARNING
The NAP port is intended for temporary local-programming purposes only and
not intended for permanent connection.
If you connect or disconnect the NAP cable with power applied to this module
or any device on the NAP 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.
Ethernet Connection
WARNING
The Ethernet port does not need to be wired for normal operation of the
linking device. The Ethernet port is used as a temporary connection to access
the embedded web pages for diagnostic purposes. The linking device has a
static IP address of 192.168.1.10.
Connect your Ethernet cable to the Ethernet port on the underside of the
linking device.
Publication
The Ethernet port is intended for temporary local-programming purposes only
and not intended for permanent connection.
If you connect or disconnect the Ethernet cable with power applied to this
module or any device on the Ethernet 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.

H1 Terminal Block
ControlNet Foundation Fieldbus Linking Device 15
WARNING
ATTENTION
IMPORTANT
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.
Be careful when stripping wires. Wire fragments that fall into the linking
device could cause damage.
The H1 RTBs are keyed so they fit only into the corresponding socket. Be
certain that you connect the cables to the correct RTBs.
You must use a power conditioner between your fieldbus power supply and
the devices on the fieldbus network. For more information, see the
F
OUNDATION Fieldbus Wiring and Installation Application Guide at
http://www.fieldbus.org,
publication AG-140.
The linking device provides two parallel terminals on each H1 network. Use
one to connect to your fieldbus devices and the other for short-term
connection of diagnostic devices.
Do these 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 desired RTB, and tighten the
screw to 0.34 N•m (3 lb•in).
3. Complete step 1
and step 2 for all H1 cables.
4. If you removed the RTB to insert the H1 cables, insert the RTB into
the corresponding socket and tighten the retaining screws.
