Introduction
This user manual describes the installation and operation of the 1788-EN2FFR
and 1788-CN2FFR linking devices.
About the Linking Devices
The 1788-EN2FFR linking device provides a gateway between an EtherNet/IP
network and a single segment FOUNDATION Fieldbus H1 layer.
The 1788-CN2FFR linking device provides a gateway between a ControlNet
network and a FOUNDATION Fieldbus network.
In this manual, both modules are referred to as the linking device.
The linking device can support up to16 field devices. It is configurable through
the Studio 5000® Logix Designer™ application by use of a dedicated Add-on
Profile (AOP). Multiple levels of media redundancy are supported, including
ring, split, and redundant trunk, plus options for H1 media, redundant linking
devices, redundant controllers, and redundant ControlNet media.
The linking device has full FOUNDATION fieldbus host capability, including
link active scheduler (LAS) capability.

This diagram shows an example of how a 1788-EN2FFR linking device could be
used with a ControlNet network.
Features
The AOP provides an intuitive graphical interface to configure devices. A
predefined data structure for each field device provides eight input process
variables (PVs), eight output PVs, and eight PVs for inter-device communication
for full distributed control.
The linking device uses four controller connections. The data for the 16 field
devices is distributed over the four CIP connections. Connection A has the data
for the linking device and four field devices. Connection B, C, and D have the
data of four field devices each. The minimum requested packet interval (RPI) is
100 ms, and the maximum is 3,000 ms.
The HSProcessUtility is used to manage and register the field device description
(DD) files. The utility is launched from the AOP in the Studio 5000 Logix
Designer application, or directly in the Microsoft Windows operating system.
Field Device Tool/Device Type Manager (FDT/DTM) technology is supported.
This allows access to field device configuration and diagnostics via FDT Frames
such as FactoryTalk® AssetCentre. In addition, the Rockwell Automation FDT
ThinFrame (read only) can be launched from a FactoryTalk View or via the AOP
providing access to each field devices status and extended diagnostics.
Rockwell Automation Publication 1788-UM057B-EN-P - September 2014 7
Preface
Built-in power conditioners and protection are provided, which helps to
minimize installation space requirements. The H1 segment is divided between
two physical ports (A and B) with individual protection and a supply of 500 mA
per port. See H1 Network Connections on page 14
The basic diagnostics of the linking device and the field devices, is found in the
input assemblies. Advanced configuration is found only through the AOP.
To assist with troubleshooting, a 128 x 128 pixel display provides access to the
status of the linking device. Information available includes network voltages and
currents, internal temperature, and communication quality to each field device.
A built-in web server provides remote access to network and field device data.

TIP
Max Scan Address
When the linking device is operating, a background scan constantly probes each
unused node number to see if any new field devices were connected. The
background scan runs to the max scan address, then restarts at one.
Slave Retry Limit
The slave retry limit sets the number of times the H1 Master re-requests data
before dropping the connection. The default setting is 5.
Do not modify the default setting. A limit above 5 can slow down
communication.
MacroCycle (ms)
The amount of time between data compels (process variables). Too low a number
can cause poor performance when downloading and going online with a field
device.
Auto Reset Trip
Selects the option to reset H1 bus trips due to over-current.
• If the checkbox is selected, the trip automatically resets. The linking device
resets the trip each 5 seconds. If the trip is still persistent, the bus will trip
again.
• If the checkbox is not selected, reset the bus via the reset button on the
master status page.
Fail Status in Prog/Fault Mode
The fail status is used when field devices use output blocks (AO or DO) that are
receiving data from the Logix controller via the linking device. When the linking
device loses connection to the Logix controller, or the Logix controller goes into
Program mode or Fault mode, you can choose one of two operations:
• If the checkbox is selected, the linking device detects that there is a comms
fault on the Ethernet network and forces all output PV status to
Bad:NoComms. If the field device is configured correctly, the field device
goes to fail-safe value.
• If the checkbox is not selected, the linking device continues to send the last
received data.
When Logix is in Prog/Fault mode, you can still go into the tags and
change values as the linking device is still connected.

Only one of the masters is the LAS that requests and receives live data from each
field device.
Follow these steps to configure one master to take priority as the primary
master.
• If the device is the LAS, the device icon is displayed without a
cross (see page 26
).
• If the device is the back-up LAS, the device icon is displayed with

Glossary
host Control system that has FOUNDATION fieldbus capabilities to configure and
operate FOUNDATION fieldbus segments. There are several classes of Host
systems:
• Class 61 - Integrated Host - Primary, or process Host that manages the
communication and application configuration of all devices on the
network.
• Class 62 - Visitor Host - Temporary, on process Host with limited access to
device parameterization.
• Class 63 - Bench Host - Primary, off process Host for configuration and
setup of a non-commissioned device.
• Class 64 - Bench host - Primary, off process Host with limited access to
device parameterization of an off-line, commissioned device.
• Class 71 - Safety Integrated Host - Primary, on-process Host that manages
the communication and application configuration of all safety and control
and monitoring devices on a network.
LAS See link active scheduler
.
link A logical link is a connection between function blocks; a physical link is a
connection between fieldbus devices.
linking device As a bridge, enables peer-to-peer communication between H1 devices without
the need for host system intervention. As a gateway, connects the H1 network to
other plant control and information networks, such as EtherNet/IP and
ControlNet.
link active scheduler Abbreviated as LAS, this scheduler is responsible for coordinating all
communication on the fieldbus; maintaining a list of transmission times for all
data buffers in all devices that need to be cyclically transmitted. The LAS
circulates tokens, distributes time, probes for new devices, and removes
non-responsive devices from the link.
link master An LM is a device that contains LAS
functionality that can control
communication on a FOUNDATION fieldbus H1 fieldbus link.
There must be at least one LM on the H1 link; one of those LM devices is
chosen as the LAS.
macrocycle A calculated time for a fieldbus device to send and receive data. The AOP can
automatically generate the value, or the value can be manually entered. The LAS
is responsible for scheduling of the segment macrocycle.
mode Control block operational condition, such as manual, automatic, or cascade.
network A network as applied in this document is the termination of one or more fieldbus
segments into an interface card of the Host system.
node The connection point at which media access is provided.
offline Perform tasks while the Host system is not communicating with the
field devices.
Rockwell Automation Publication 1788-UM057B-EN-P - September 2014 93
Glossary
online Perform tasks, such as configuration, while the Host system is communicating
with the field devices.
PV Acronym for Process Variable, which is the primary value.
resource block (RES) This block controls the linking device. It contains data specific to the linking
device’s hardware. All data is modeled as contained, so there are no links in this
block.
redundancy The duplication of devices for the purpose of enhancing the reliability or
continuity of operations in the event of a failure without loss of a
system function.
ring bus A network where signals are transmitted from one station and replayed through
each subsequent station in the network. Signal can travel in either direction of the
ring so it creates network redundancy; if the ring breaks in one place the nodes
can still communicate.
RSLogix Software that provides a programming environment for sequential, process, drive,
and motion control programming. The RSLogix environment provides an IEC
61131-3 compliant interface for controls programming.
segment A physical link (cable) between fieldbus devices and a pair of terminators on
an H1 channel. Segments can be linked by repeaters to form a longer H1 fieldbus.
A fully loaded (maximum number of connected devices) 31.25 Kbps
voltage-mode fieldbus segment should have a total cable length, including spurs,
between any two devices of up to 1900 m. There cannot be a non-redundant
segment between two redundant systems.
signal The event or electrical quantity that conveys information from one point to
another.
tag Unique alphanumeric code assigned to inputs, outputs, equipment items, and
control blocks.
terminator Impedance-matching module used at or near each end of a transmission line that
has the same characteristic impedance of the line. Terminators are used to
minimize signal distortion, which can cause data errors. H1 terminators convert
the current signal transmitted by one device to a voltage signal that can be
received by all devices on the network.
topology The shape and design of the fieldbus network.
transducer block The transducer block decouples function blocks from the local
input/output (I/O) function required to read sensors and command output
hardware. Transducer blocks contain information, such as calibration date and
sensor type. There is usually one transducer block for each input or output of a
function block.
trunk The main communication highway between devices on an H1 fieldbus network.
The trunk acts as a source of main supply to spurs on the network.
94 Rockwell Automation Publication 1788-UM057B-EN-P - September 2014
Glossary
VCR Acronym for Virtual Communication Relationship. Configured application
layer channels that provide for the transfer of data between applications.
FOUNDATION Fieldbus describes three types of VCRs: Publisher/Subscriber,
Client/Server, and Source/Sink.
