Overview
- Construction of optical PROFIBUS networks (line, star, ring) with glass, PCF and plastic fiber-optic cables
- High availability can be achieved using a redundant power supply and redundant cable routing
- Function monitoring by means of signaling contact
- All PROFIBUS data transmission rates from 9.6 Kbit/s to 12 Mbit/s including 45.45 Kbit/s for PROFIBUS PA
- Monitoring of the fiber-optic cable routes on LEDs for channel monitoring or using a voltmeter across measurement terminals
Note:
SIPLUS extreme products are based on SIMATIC standard products. The contents listed here were adopted from the respective standard products. SIPLUS extreme-specific information was added.
Application
With the PROFIBUS OLM (Optical Link Modules), optical PROFIBUS networks can be established in linear, star and redundant ring topologies.
The data transfer rate of a fiber-optic line is independent of the distance and can reach up to 12 Mbps.
Possible applications for OLMs include:
- System buses based on PROFIBUS
- Networking between buildings using glass fiber-optic cables
- Mixed networks with electrical and optical segments
- Networks covering a wide area (road tunnels, traffic control systems)
- Networks with high availability requirements (redundant ring networks)
Design
The OLMs have a compact metal housing. It is suitable for mounting on a standard rail or for wall mounting with a mounting plate.
The 24 V power supply is fed in through a terminal block and can be redundantly connected.
The signaling contact allows a digital signal to be transferred to PLCs or HMI systems for evaluation.
OLMs can be combined with each other and individual stations or complete electrical segments can be integrated into the optical PROFIBUS network through an electrical interface. With the PROFIBUS OLM P22 and OLM G22, two electric PROFIBUS segments can be connected separated from each other.
OLMs are available with one or two fiber optic interfaces with BFOC connectors for different types of fiber optic cables:
- Plastic fiber-optic cables (980/1000 µm) can be used for single lengths of up to 80 m. They can also be assembled with BFOC cable connectors on site.
- PCF fiber-optic cables (200/230 µm) can be used for single lengths of up to 400 m. They are offered preassembled with four BFOC plugs and an insertion tool.
- Glass fiber multimode fiber-optic cables (62.5/125 µm) such as the SIMATIC NET Fiber Optic cables can be used for long distances of up to 3000 m. They must be ordered preassembled with 4 BFOC plugs or as a FastConnect FO system for assembly on site.
- Singlemode fiber-optic cables (10/125 µm or 9/125 µm fibers) can be used for extremely long distances up to 15 km.
Function
- Automatic detection of all PROFIBUS data transfer rates 9.6 Kbps to 12 Mbps inclusive 45.45 Kbps (PROFIBUS PA)
- Construction of the following network topologies: Line, star, redundant ring
- High availability due to media redundancy. The distance between two OLMs in the redundant ring is only limited by the optical range of the modules
- RS485 interface with segment capability (Sub-D female connector)
- Unrestricted multimaster operation: Expanded segmentation functions for localization of faults to fiber-optic and RS485 segments
- Fast localization of faults:
- Indication of module status through floating signaling contact
- Checking the fiber-optic cable route quality on LEDs
- Checking the fiber-optic cable route quality Measurement output for optical receiver for logging and plausibility checking of the fiber-optic path attenuation with a voltmeter
- High cascading depth: Line and redundant ring up to 124 OLM (only limited by monitoring times)
