Preface
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.

be used with an EtherNet/IP network..

Preface
1788-CN2FFR ControlNet Network
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.

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.
Safety Precautions Read and understand all precautions before using the linking device.
Prevent Electrostatic Discharge
ATTENTION: Prevent Electrostatic Discharge
This equipment is sensitive to electrostatic discharge, which can cause internal
damage and affect normal operation. Follow these guidelines when you handle
this equipment
•Touch a grounded object to discharge potential static.
•Wear an approved grounding wriststrap.
•Do not touch connectors or pins on component boards.
•Do not touch circuit components inside the equipment.
•Use a static-safe workstation, if available.
•Store the equipment in appropriate static-safe packaging when not in use.
