2 2 Introduction 2.1 Introduction This chapter gives an overview on the functions of the PROFIBUS OLM4.0 product family. What Is Possible? PROFIBUS OLMs are designed for the use in optical PROFIBUS field bus networks. They allow the conversion of electrical PROFIBUS interfaces (RS 485 level) into optical PROFIBUS interfaces and vice versa. The modules can be integrated into existing PROFIBUS field bus networks – under utilization of the known advantages of the optical transmission technology.
Introduction 2.1 Introduction Every module has two (OLM P11, G11) or three (OLM P12, G12) independent channels (ports), which consist of a transmission and a receiving unit. The operation voltage supply is realized with 24 V DC voltage. To increase the operation safety a redundant feed is possible. The electric channel is designed as 9-pin sub-D socket (female). A RS 485 bus segment according to PROFIBUS standard EN 50170 /2/ can be connected to this channel.
Introduction 2.1 Introduction The PROFIBUS OLMs meet the requirements for the standard EN 50170 /2/ as well as for the technical directive “Optical transmission technology for PROFIBUS” which was edited by the PROFIBUS user organization (PNO). OLM/G12 and OLM/G12-EEC have the same functions.
Network Topologies 2.1 Introduction 3 Network Topologies 3 Which network topologies can be implemented? The following network topologies can be realized with the PROFIBUS OLM: • Point to point connection • Bus Topology • Star Topology • Redundant optical ring Combinations of this basic types are possible as well. For the setup of the fiber optic cables of these network topologies, lines with two optical fibers are used. If in the case of failure – e.g.

Network Topologies 3.1 Bus Topology 3.1.1 Bus topology with fiber optic cable distance monitoring and segmentation Use this operation mode especially when a distorted fiber optic cable segment shall be seperated from the rest of the network (see chapter 4.2.2.4). Only use this operation mode, if you connect PROFIBUS OLM V4.0 or V3/V4.0 with each other only.
Network Topologies 3.2 Star Topology 3.
Network Topologies 3.2 Star Topology For the setup of a active PROFIBUS star coupler modules with one or two optic channels can be used. For the connection of a DTE or of a RS 485 bus segment to an active star coupler, modules with one optical channel are enough. When the distance monitoring on the optical channels is on, a monitoring of the fiber optic cables by means of the respectively connected OLMs is given.

Network Topologies 3.3 Ring Topology Please observe: For a correct operation the following frame conditions have to be met: Only use this operation mode, if you optically connect PROFIBUS OLM with at least Version V3 with each other only. Both optical channels have to be set to the operation mode “redundant optical ring” at all PROFIBUS OLMs. All modules within a ring have to be connected via fiber optical cables with each other. There must be no RS 485 bus line within the ring.
Network Topologies 3.3 Ring Topology 3.3.1 Redundant Optical Ring with two OLMs The setup of a redundant optical ring with two PROFIBUS OLMs can be seen as special case of the redundant optical ring and can be realized with the following two configurations.

Product Characteristics 4.2 Installation 4.2 Installation 4.2.1 Safety related notices Only use the PROFIBUS OLM in the way intended in this operation manual. Especially observe all warnings and safety relevant notices. Run the modules only with a safety extra-low voltage of a maximum of +32 V (typically +24VDC) according to IEC 950 / EN 60 950 / VDE 0805. According to the UL/CSA-approval, the power supply unit has to meet the requirements of the NEC, Class 2.
Product Characteristics 4.2 Installation General information on the commissioning 4.2.2 Unpack the OLM V4.0 and its accessories and check on completeness and potential transport damage. After unpacking, the device should be acclamatized for an appropriate time to avoid condensation after to storage in cold surrounding. At first choose the network topology suitable for your requirements.
Product Characteristics 4.2 Installation 4.2.3 Setting of compatibility, operation mode and transmission rate Please observe: The OLM must be switched off when changing the operation mode. You can achieve this for example by pulling the 5-pin terminal block. 4.2.3.1 Setting the compatibility With DIL switch S7 the functional compatibility with devices of the prior generation SINEC L2FO OLM/P3, -P4, -S3, -S4, S3-1300 and S4-1300 is switched on or off.

Product Characteristics 4.2 Installation Operation mode electrical channel without segment monitoring “ “ CH1 is set to this mode, when S0 is in position 1. Note: Observe that this operation mode should only be set in the star segment of the star topology. 4.2.3.4 Setting the operation mode of the optical channels (CH2, CH3) The operation mode can be set seperately for each optical channel.
Product Characteristics 4.2 Installation 4.2.3.5 Reducing the optical transmission rate at OLM/P11 and OLM/P12 Notice! The following information is only valid for the default setting of S7 (S7=0)! The OLM/P11 and OLM/P12 have a high optical transmission rate. The connection of these modules with non-OLM-devices via plastic fiber-optic cables can lead to optical override, especially if short cables are used. In this case, the optical transmission rate can be reduced by approx. 60% (3.8 dB).
Installation and Maintenance 5.1 Installation 5 Installation and Maintenance 5 5.1 Installation 5.1.1 Installation instructions Electromagnetic Compatibility The electromagnetic compatibility comprises all questions on electric, magnetic and electromagnetic emission effects. To avoid disturbing influences on electrical installations, these effects have to be cut down to a minimum.
Installation and Maintenance 5.1 Installation Please observe: In between an OLM and a load switching element (e.g. contactor, relais, temperature control, switch, etc.) a minimum distance of 15 cm has to be kept. This minimum distance is to be measured between the outside edges of the components and must be kept in all directions around an OLM. The power supply lines (24 VDC) of the OLM may not be passed in the same cable duct with load carrying lines (load circuits).
Installation and Maintenance 5.1 Installation line mantle. Tin-plated or galvanically stabilized surfaces are perfect for a good contact between grounding elements. In case of tin-plated surfaces, the necessary contacts have to be assured by corresponding screwing. Coated surfaces at the contact points are inapplicable. Shielding contacts may not be used as strain relief. The contact to the shielding rail could decrease or tear off.
Installation and Maintenance 5.1 Installation 5.1.2 Connection of the optical lines Connect the single modules via a two-core fiber-optic cable with BFOC/2.5 connectors. Observe – that the end planes of the optical connectors are dirt-free. – that always one optical input : y and one optical output :z are interconnected (“cross connection“). The corresponding BFOC jacks of a channel are marked on the lower end plane.
Installation and Maintenance 5.2 Installation of the modules 5.2 Installation of the modules Installation possibilities The OLM modules can either be mounted on a 35 mm rail according to DIN EN 50022 or a plane surface by means of a mounting plate. Choose the assembly place so that the climatical and mechanical limit values, given in the technical data, can be met. Observe that there is enough space for the connection of the bus and voltage supply lines.
Installation and Maintenance 5.3 Connection of the electrical RS 485 bus lines Installation on a mounting plate Fix the module to the mounting plate with 3 screws M3x8 (accessories, Order-No. A2B00065949), torque 0.8 Nm. Fix the mounting plate at the desired installation position. Assure a safe and permanent electrical connection between mounting plate and surface by using lock washers for example. Installation of a module with a mounting plate Figure 5-5 5.
Installation and Maintenance 5.3 Connection of the electrical RS 485 bus lines All PROFIBUS bus connectors of the network have to be screwed tight to the RS485 interfaces. Connecting or pulling the bus connector or loosely connected bus connectors or not tightly screwed bus cores inside the connectors can lead to distortions in the optical and electrical network. Connect or pull the RS 485 bus connector quickly and without tilting the connector.
Installation and Maintenance 5.4 Connection of the operation voltage supply 5.4 Connection of the operation voltage supply L1+ F1 M F2 L2+ Figure 5-7 Operation voltage supply, pin assignment 5 pin terminal block The terminal block can be pulled off the device for the connection of the lines. Supply the module only with a stabilized safety extra-low voltage of a maximum of +32 V (typically +24V) according to IEC 950 / EN 60 950 / VDE 0805.
Installation and Maintenance 5.6 Receiving level of the optical channels 5.6 Receiving level of the optical channels The input level of the two optical channels CH2 und CH3 can be detected by means of a standard volt meter via the recording jacks. The volt meter can be connected and disconnected during running operation. The OLM is protected against a short circuit at the recording jacks, the data transmission will not be influenced.
Installation and Maintenance 5.7 LED displays and error search Note: For a valid recording value it is necessary, that the partner OLM at the other end of the fiber-optic cable sends regular PROFIBUS telegrams. This can be detected by means of the LED display of the partner OLM (see chapter 5.7.1).
