Rockwell Automation 1786-series ControlNet Fiber Media Planning and Installation Guide - Manual (Page 26)

26 Rockwell Automation Publication CNET-IN001C-EN-P - October 2011
Chapter 1 Get Started with the ControlNet Network Fiber Media System
Terminate Your Fiber Cable Be sure to use the correct connectors on the end of your fiber cable for the best
optical and mechanical connections. For example, ST- and V-pin are the only two
connectors that the ControlNet network recognizes.
See Table 8 on page 54 for more information on available connector kits for
repeater modules.
You also want to use a dust cap on an unconnected terminated fiber cable end if a
connector is not going to be used.
Test Your Fiber Media
Connections and Segments Many field testers are available to test the connectors on cable that is used with
the 1786-RPFM, 1786-RPFRL/B and 1786-RPFRXL/B repeater modules.
Consult with your fiber network specialist to determine which tester is the best
for your media.
Power Your Repeaters The power for your fiber repeaters comes from the repeater adapters. The
repeater adapters must be powered by using a 24V power supply.
See page 68 for the 1786-RPA/B repeater adapter installation instructions and
power supply requirements.
Verify Your Network Verify whether your system meets the network parameter requirements.
1. In RSNetWorx for ControlNet software, go online, browse your network,
and look for invalid node addresses.
2. OTDR and fiber field testers will help make sure that no segments violate
distance constraints.
3. Make sure your network does not violate general network rules.
See Chapter 3, starting on page 43 , for details.
4. Isolate a single segment of the network and verify its operation.
5. Connect multiple segments of the network , being mindful of bandwidth,
insertion loss of the segment, and segment length.
6. Verify that the correct connectors and cable have been installed.
See page 55 for additional information.
