2 ControlNet Ex Modular Repeater Adapter & Fiber Repeater Module
Important User Information
Solid state equipment has operational characteristics differing from those of electromechanical equipment. Safety Guidelines for the Application, Installation and Maintenance of Solid State Controls
(Publication SGI-1.1 available from your local Rockwell Automation sales office or online at http://www.literature.rockwellautomation.com
) describes some important differences between solid state equipment and hard-wired electromechanical devices. Because of this difference, and also because of the wide variety of uses for solid state equipment, all persons responsible for applying this equipment must satisfy themselves that each intended application of this equipment is acceptable.
In no event will Rockwell Automation, Inc. be responsible or liable for indirect or consequential damages resulting from the use or application of this equipment.
The examples and diagrams in this manual are included solely for illustrative purposes. Because of the many variables and requirements associated with any particular installation, Rockwell Automation, Inc. cannot assume responsibility or liability for actual use based on the examples and diagrams.
No patent liability is assumed by Rockwell Automation, Inc. with respect to use of information, circuits, equipment, or software described in this manual.
Reproduction of the contents of this manual, in whole or in part, without written permission of Rockwell

ATTENTION
Environment and Enclosure
This equipment is considered Group 1, Class A industrial equipment according to IEC/CISPR Publication 11. Without appropriate precautions, there may be potential difficulties ensuring electromagnetic compatibility in other environments due to conducted as well as radiated disturbance.
This equipment is supplied as open-type equipment. It must be mounted within an enclosure that is suitably designed for those specific environmental conditions that will be present and appropriately designed to prevent personal injury resulting from accessibility to live parts. The interior of the enclosure must be accessible only by the use of a tool. Subsequent sections of this publication may contain additional information regarding specific enclosure type ratings that are required to comply with certain product safety certifications.

About the ControlNet Ex Fiber Repeater Hub
Use the repeater adapter (1797-RPA) and the fiber module (1797-RPFM) together to form a repeater hub within the hazardous area to extend the length of the ControlNet Ex segments to interlink systems all operating within the area.
The 1797-RPA repeater adapter, configured with at least one repeater adapter, functions as the intelligent starter block for a multiport repeater. The
1797-RPFM is a nonintelligent fiber-to-backplane conversion device, converting glass-fiber infrared LED media signals to backplane signals for use by the 1797-RPA.
A maximum of two 1797-RPFM modules may be used with one 1797-RPA adapter.

DIN-Rail Mount the 1797-RPA and -RPFM
Refer to Mounting Dimensions on page 31. For panel mounting information, see publication 1794-5.13.
ATTENTION
This product is grounded through the DIN rail to the dedicated intrinsic safety ground. Use zinc-plated yellow-chromate steel
DIN rail to assure proper grounding. The use of other DIN rail materials (such as aluminum or plastic) that can corrode, oxidize, or are poor conductors, can result in improper or intermittent grounding.
1.
Position the module on a 35 x 7.5 mm DIN rail (A-B part number
199-DR1) at approximately a 30 o angle.
41167
ATTENTION
The DIN rail or mounting bracket must be appropriately connected to the dedicated intrinsic safety ground.
2.
Hook the lip on the rear of the adapter onto the top of the DIN rail, and rotate the module onto the rail.
41166

3.
Press the adapter down onto the DIN rail until flush.
The locking tab should snap into position and lock the module to the
DIN rail.
ATTENTION
Make certain that the adapter and fiber modules are secured together with DIN rail anchors. Failure to do so may result in the loss of communications, cause damage to the modules, or both.
4.
If the adapter does not snap into position, use a screwdriver or similar device to move the locking tab down while pressing the module flush onto the DIN rail.
Release the locking tab to lock the module in place. If necessary, push up on the locking tab to lock.
41168
5.
Remove the adapter backplane connector cover.
6.
Follow steps 1 to 4 to attach fiber modules to the DIN rail.
7.
Once attached to the DIN rail, slide fiber modules to the left to mate with the adapter.
Publication 1797-IN015G-EN-P - August 2017
ControlNet Ex Modular Repeater Adapter & Fiber Repeater Module 7
IMPORTANT
41169
A DIN-rail end anchor (A-B part number 1492-EA35) must be used on the left side of the adapter and on the right side of the fiber module to keep the units from moving.
8.
Make sure the last fiber module has its backplane connector cover in place.
9.
Connect the adapter wiring as shown below in the Wiring section.
IMPORTANT
You can only attach two media modules to the repeater adapter. If you exceed the module limit, you may cause damage to the adapter or fiber modules and void the IS certification.

Screw terminals and spring terminals are provided.
4.
Strip the +V and -V wires to a length so no bare conductor shows after inserting the wires into position.
5.
If you are using the spring terminals of the plug, insert a screwdriver into the slot and carefully pry until the spring clamp opens to accept the wire.
WARNING
Do not use any unused terminals on this adapter. Using these terminals as supporting terminals can result in damage to the module and unintended operation of your system.
Make certain that you power this adapter with an intrinsically safe power supply. Do not exceed the values listed in the specifications for this adapter.
Do not remove or replace a module when power is applied.
Interruption of the bus can result in unintended operation or machine motion.
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.
Publication 1797-IN015G-EN-P - August 2017
IMPORTANT
ControlNet Ex Modular Repeater Adapter & Fiber Repeater Module 15
Make sure all fiber modules are attached and secured prior to applying intrinsically safe power to the adapter. Failure to do so may cause damage to the adapter and modules.
Describing the ControlNet Ex System Diagram
A maximum of 48 ControlNet Ex nodes may be connected together by 250 m
(820 ft) of coax cable and 48 taps. The distance to increases to 1000 m (3280 ft) when you use only 2 taps. See the table below for more information.
The fiber media of the 1797-RPFM can be installed in a hazardous location
(Zone 0, 1 or 2; Class I, Zones 0, 1, and 2; Class I, Division 1 and 2; Class II,
Division 1 and 2; Class III, Division 1 and 2) to connect two 1797-RPFM modules or they can be installed through different locations into the nonhazardous location to connect the 1797-RPFM with any approved associated apparatus.
All cables and fiber media that are not light blue must be marked as IS using the 1797-EXMK marking kit or other locally approved IS identification or segregation method.
During the installation of the ControlNet Ex system, all metallic parts must be isolated to prevent an earth connection (high voltage withstanding of isolating material must be > 500V ac).

This Indicates
The adapter is being powered-up or reset. The LEDs alternately flash red and green for about 5 s.
Normal operation.
The unit is not powered. Check the module power status.
There is an adapter fault.
If the fault indication is caused by a jabber condition, the fault indication will automatically be cleared when the jabber condition is removed from the coax or fiber port.
If a jabber condition is not causing the fault, replace the repeater adapter.

The Respective Segment (1 or 2) is
Experiencing temporary network errors.
The situation will normally correct itself. If the situation persists, troubleshoot your nodes and cable system. When troubleshooting your cable system, make sure:
• all BNC connector pins are properly sealed.
• all taps are A-B taps.
• all terminators are 75
Ω
and are installed at both ends of all segments.
Experiencing a high level of network errors.
This may indicate a broken cable, broken tap, or missing segment terminator.
Important: The indicators will flash red/off when a system has no network activity. This would be normal for a system that has no
ControlNet nodes installed or enabled.
