Using Fiber Converter Modules

Introduction

The 140 NRP 312 00/01 and BMX NRP 0200/01 fiber converter modules are an alternative method to using a to provide fiber optic communications in a Quantum EIO system.

NOTICE

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.

Keep caps on jumpers and transceivers when not in use.
Insert the optical cable into the transceivers carefully, respecting the longitudinal axis of the transceiver.
Do not use force when inserting the cable into the optical transceivers.

Failure to follow these instructions can result in equipment damage.

The following table describes the 2 types of fiber converter modules:

	BMX NRP 0200	BMX NRP 0201	140 NRP 312 00	140 NRP 312 01
rack/drop type	X80	X80	Quantum	Quantum
fiber type	multi-mode	single-mode	multi-mode	single-mode
multi-mode: used for distances less than 2 km single-mode: used for distances between 2 km and 15 km

You can install fiber converter modules to:

extend the total length of the Quantum EIO network when you have Ethernet remote I/O 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 buildings

The following figure shows a Quantum EIO system with Quantum remote I/O drops only using 140 NRP 312 00/01 fiber converter modules to extend the distance between drops beyond 100 m. Connect the fiber and copper cables to the correct ports on the module as shown in the following figure. Refer to the 140 NRP 312 00/01 Fiber Converter Module User Guide for details.

NOTE: You can install fiber converter modules on the main ring and sub-rings for copper-to-fiber transitions. However, you cannot use these modules to connect sub-rings to the main ring. Use a dual-ring switch (DRS) with an appropriate predefined configuration file to attach a sub-ring to the main ring.

Installing Fiber Converter Modules

To install fiber converter modules and convert to fiber, follow these steps:

Step	Action
1	Install a 140 NRP 312 00/01 fiber converter module on a Quantum rack. — or — Install a BMX NRP 0200/01 fiber converter module on an X80 rack.
2	To connect a fiber converter module to the 140CRP31200 remote I/O head module on the local rack, install a 140 NRP 312 00/01 module and connect to the head module using copper cable.
3	To install a fiber converter module on a remote I/O drop: For a Quantum remote I/O drop, install a 140 NRP 312 00/01 module directly on the drop. For an Modicon X80 remote I/O drop, install a BMX NRP 0200/01 module on an X80 rack.
4	Connect the 140 NRP 312 00/01 module on the Quantum local rack to a 140 NRP 312 00/01 module on a remote I/O drop on the main ring. The fiber converter modules use small form-factor plugs (SFPs) (transceivers) for the fiber ports. Choose single-mode or multi-mode SFPs. Use the multi-mode fiber module (140 NRP 312 00 or BMX NRP 0200) if the distance between the NRP and the next Ethernet remote I/O drop is less than 2 km. Use the single-mode fiber module (140 NRP 312 01 or BMX NRP 0201) if the distance between the NRP and the next Ethernet remote I/O drop is between 2 km and 15 km.
5	To extend the fiber cable on the main ring to other remote I/O drops on the main ring, repeat steps 3 and 4.
6	To convert the fiber cable to copper cable on the main ring, connect the •••CRA312•0 adapter module on the last remote I/O drop that is connected to the main ring via fiber cable to a •••CRA312•0 adapter module on the next remote I/O drop.
7	To close the main ring, connect the •••CRA312•0 adapter module on the last remote I/O drop that is connected to the main ring via copper cable to the 140CRP31200 module on the local rack.

Using Fiber Converter Modules in a Long-Haul Hot Standby Link

You can use 140 NRP 312 00/01 fiber converter modules in a long-haul link to extend the distance between the 2 PLCs beyond 100 m. Use NRP modules to connect to in a high-capacity daisy chain loop system when you wish to have Ethernet remote I/O or distributed I/O or .

NOTE: Connect the fiber and copper cable to the correct ports on the NRP modules as shown in the following figure. Refer to the 140 NRP 312 00/01 Fiber Converter Module User Guide or the BMX NRP 0200/01 Fiber Converter Module User Guide for details.

To install NRP modules in a Quantum EIO system to extend the distance between 2 PLCs in a long-haul Hot Standby link beyond 100 m, follow these steps:

Step	Action
1	Install a 140 NRP 312 00/01 fiber converter module on both Quantum Hot Standby local racks.
2	Connect the fiber transceiver ports of the 140 NRP 312 00/01 modules on both racks to each other, using fiber cable. Use 140 NRP 312 00 modules to support multi-mode fiber if the distance between them is less than 2 km. Use 140 NRP 312 01 modules to support single-mode fiber if the distance between them is between 2 km and 15 km.
3	Connect the copper port of the 140 NRP 312 00/01 module to the 140CRP31200 remote I/O head module on both local racks, using copper cable.
