Introduction
The BMXNRP020• fiber converter module is an alternative method to using a DRS to provide fiber optic communications in an M580 system.
You can install BMXNRP020• fiber converter modules on extended local racks and RIO drops to:
Extend the total length of the M580 network when you have Ethernet RIO drops in separate areas of a factory that are more than 100 m apart.
Improve noise immunity
Resolve possible grounding issues when using different grounding methods is required between 2 sites.

UNINTENDED EQUIPMENT OPERATION When installing modules with fiber optic transceivers,
do the following to help prevent dust and pollution from disrupting
light production into the fiber optic cable.
Failure to follow these instructions can result in equipment damage. | |
This table describes the BMXNRP020• fiber modules:
Module |
Fiber Type |
Use for distances... |
|---|---|---|
BMXNRP0200 |
multi-mode |
less than 2 km |
BMXNRP0201 |
single-mode |
up to 15 km |
You cannot use BMXNRP020• modules to connect sub-rings to the main ring:
- - - - fiber cable
—— copper cable
1 CPU with Ethernet I/O scanner service on the local rack
2 BMENOC0301 module on the local rack, managing distributed equipment on the EIO network
3 BMXNRP0200 fiber converter module on the local rack
4 BMENOC0321 module on the local rack, providing transparency between the EIO network and the control network
5 control network
6 BM•CRA312•0 X80 EIO adapter module connecting an RIO drop to the main ring
7 BMXNRP0200 module on an RIO drop connected to the main ring via fiber cable to extend the distance between the RIO drop and the local rack
8 fiber cable portion of the main ring
9 copper cable portion of the main ring
10 invalid copper connection from a BM•CRA312•0 module on an RIO drop on the main ring to an RIO sub-ring
11 invalid fiber connection from a BMXNRP0200 module on an RIO drop on the main ring to an RIO sub-ring. You cannot use a BMXNRP020• module to connect a sub-ring to the main ring.
12 The BM•CRA312•0 module on this valid RIO drop is connected to the main ring via copper cable from the BM•CRA312•0 module and via fiber cable from the BMXNRP020• module. The BM•CRA312•0 module and the BMXNRP020• module are interlinked.
Extending Distance Between the Local Rack and an RIO Drop
The procedures for installing fiber between the local rack and a remote drop were described earlier in this manual.
The procedure for installing fiber between contiguous drops in an RIO network are described as well.
Interlinking BMXNRP020• Modules on X Bus Racks
For a system that uses X Bus racks (not Ethernet racks), interlink the copper ports of a BMXNRP020• module with the Ethernet ports of a BM•CRA312•0 X80 EIO adapter module on RIO drops:
- - - - fiber cable (used for distances greater than 100 m)
—— copper cable (used for distances less than 100 m)
1 An M580 CPU with Ethernet I/O scanner service on the local rack.
2 A BMXNRP0200 module on a Modicon X80 rack converts copper cable to fiber for distances greater than 100 m.
3 A BMENOC0321 module on the local rack provides transparency between the EIO network and the control network.
4 (e)X80 drops are connected to the main ring via copper and fiber cable. BM•CRA312•0 (s)X80 EIO adapter modules connect the drops via copper cable, and BMXNRP0200 modules connect the drops via fiber cable.
5 (e)X80 drops are connected to the main ring via fiber cable using a BMXNRP0200 module.
6 (e)X80 drops are connected to the main ring via copper cable.
Diagnosing Fiber Converter Modules
To diagnose the BMXNRP020• fiber converter modules, refer to the BMX NRP 0200/0201 M340/X80 Fiber Converter Module User Guide.
