2 2.1 2 Introduction Introduction This section provides you with an overview of the functions of the PROFIBUS OLM4.0 product family. What is possible? PROFIBUS OLMs are designed for use in optical PROFIBUS fieldbus networks. They allow the conversion of electrical PROFIBUS interfaces (RS-485 level) into optical PROFIBUS interfaces and vice versa. The modules can be integrated in existing PROFIBUS fieldbus networks with the known advantages of optical transmission technology.
Introduction 2.1 Introduction Every module has two (OLM P11, G11), three (OLM P12, G12), or four (OLM P22, G22) independent channels (ports) that consist of transmitter and receiver pairs. The power supply voltage for operation is 24 V DC. To increase operational reliability, a redundant power supply is possible. The electrical channel is designed as 9-pin D-sub socket. An RS-485 bus segment complying with PROFIBUS standard EN 50170 /2/ can be connected to this channel.
Introduction 2.1 Introduction The PROFIBUS OLMs comply with the standard EN 50170 /2/ and with the technical guideline “Optical transmission technology for PROFIBUS” published by the PROFIBUS User Organization (PNO). OLM / G12 and OLM / G12-EEC have the same functions.
3 Network Topologies 3 Which network topologies can be implemented? The following network topologies can be implemented with the PROFIBUS OLM: • Point-to-point connection • Bus (linear) topology • Star topology • Redundant optical ring Combinations of these basic types are also possible. To set up the fiber-optic links of these network topologies, cables with two optical fibers are used.
Network Topologies 3.1 Linear (bus) Topology 3.1 Linear (bus) Topology Figure 3-1 Network structure in a linear (bus) optical topology * If OLM / P22 or OLM / G22 are used, an additional DTE or bus segment can be connected to Ch 0. In a linear or bus structure, the single PROFIBUS OLMs are connected by two-fiber cables. At the beginning and at the end of a line, modules with one optical channel are adequate, inbetween modules with two optical channels are necessary.
Network Topologies 3.1 Linear (bus) Topology 3.1.1 Linear (bus) topology with fiber-optic link monitoring and segmentation Use this mode especially when you want a disrupted fiber-optic cable segment to be separated from the rest of the network (see section 4.2.2.4). Only use this mode, if you only connect PROFIBUS OLM V4.0 or V3/V4.0 with each other.
Network Topologies 3.2 Star Topology 3.
Network Topologies 3.3 Ring Topology Note: Unused optical channels you intend to use later to expand the network cause a broken fiberoptic cable signal if the monitoring is active. You can avoid this error message by setting unused channels to the mode “bus without fiber-optic link monitoring”. Remember that the optical channels that are not connected must be protected against external light and pollution by protective caps. 3.3 3.3.
Network Topologies 3.3 Ring Topology If one module fails, only the DTEs connected to this module or the RS-485 segment are disconnected from the ring. The rest of the network itself stays functional as a bus. The problem is indicated by the LEDs of the two OLMs connected to the disrupted fiber-optic link and by the signaling contacts of these OLMs.
Network Topologies 3.3 Ring Topology 3.3.2 Redundant Optical Ring with two OLMs Setting up a redundant optical ring with two PROFIBUS OLMs can be seen as special case of the redundant optical ring and can be implemented with the following two configurations. Figure 3-4 * Configuration 1 Figure 3-5 Configuration 2 If OLM / P22 or OLM / G22 are used, an additional DTE or bus segment can be connected to Ch 0.
Network Topologies 3.3 Ring Topology Configuration 1 (see Figure 3-4, FOC1 < FOC2) , LED display: 1. Situation, no FOC interruption: OLM 1 OLM 2 SystemLED = lit green SystemLED = lit green CH1/0 LED = lit yellow CH1/0 LED = lit yellow CH2 LED = lit yellow CH2 LED = is not lit CH3 LED = is not lit CH3 LED = lit yellow 2.
Network Topologies 3.3 Ring Topology 3. Fault, FOC2 interrupted: OLM 1 OLM 2 SystemLED = lit green SystemLED = lit green CH1/0 LED = lit yellow CH1/0 LED = lit yellow CH2 LED = lit yellow CH2 LED = lit yellow CH3 LED = lit red CH3 LED = lit red 2. The redundant optical ring consists of exactly two OLMs and both fiber-optic cable connections are of exactly the same length. Under these circumstances, that the receiving OLM receives a frame on both of the optical channels at the same time.

Product Characteristics 4.2 Installation Mode “electrical channel without segment monitoring“ CH1 is set to this mode, when S0 is in position 1. Note: This mode should only be set in the star segment of the star topology. 4.2.3.4 Setting the mode of the electrical channel (CH0) Only for OLM / P22 and OLM / G22 Mode “electrical channel with segment monitoring“ CH0 is set to this mode, when S8 is in position 0.
Product Characteristics 4.2 Installation 4.2.3.6 Reducing the optical transmit power Notice! The following information is only valid for the default setting of S7 (S7=0)! for OLM / P11, OLM / P12, and OLM / P22 The OLM / P11, OLM / P12, and OLM / P22 have a high optical transmit power. Connecting these modules with non-OLM devices via plastic fiber-optic cables can lead to optical overdrive, especially if short cables are used. In this case, the optical transmit power can be reduced by approx. 60% (3.

5 5.1 Installation and Maintenance 5 Installation 5.1.1 Installation instructions Electromagnetic compatibility Electromagnetic compatibility involves all questions regarding electric, magnetic and electromagnetic emission effects. To avoid disturbing influences on electrical installations, these effects must be reduced to a minimum. The construction of device, correct connection of bus lines and the suppression of self inductances are essential limitation measures. See also the note in section 4.2.
Installation and Maintenance 5.1 Installation Please note the following: A minimum distance of 15 cm must be maintained between an OLM and a load switching element (e.g. contactor, relay, temperature control, switch, etc.). This minimum clearance is measured between the outside edges of the components and must be adhered to in all directions around an OLM. The power supply lines (24 V DC) of the OLM must not be laid in the same cable duct as power lines (load circuits).
Installation and Maintenance 5.1 Installation Shield connections Figure 5-2 Securing shielded cables with cable clamps and cable retainers (schematic image) Please note the following points when connecting the cable shield: Connect the shield braid with cable clamps made of metal. The clamps must surround the shield making good contact over a large area (see Figure 5-2). Only contact the SIMATIC NET PROFIBUS cables via the copper braid shield and not via the aluminum foil shield.
Installation and Maintenance 5.1 Installation Example: OLM / G12, wavelength 860 nm, fiber 62.5/200 µm Psend = 13 dBm Preceiver = 28 dBm optical link margin = 28 dBm -13 dBm= 15 dBm max. line length = 3 km attenuation = 3.5 dB/km @ 860 nm max. line attenuation = 3.5 dB/km * 3 km = 10.5 dB optical power margin = optical link power budget – max. line attenuation = 15 dBm – 10.5 dBm = 4.
Installation and Maintenance 5.1 Installation 5.1.2 Connecting optical cables Figure 5-3 View of the module from below with optical channels 2 and 3 (device with two optical channels) Connect the single modules via a two-core fiber-optic cable with BFOC/2.5 connectors. Make sure – that the end faces of the optical connectors are clean. – that always one optical input and one optical output are interconnected (“crossover connection“).
Installation and Maintenance 5.2 Installation of the Modules 5.2 Installation of the Modules Installation options The OLMs can either be mounted on a 35 mm rail according to DIN EN 50022 or on a flat surface with the help of a mounting plate. Choose the location so that the climatic and mechanical limit values listed in the technical specifications can be met. Make sure there is enough space to connect the bus and voltage supply lines. Connect the fiber-optic cables before you install the modules.
Installation and Maintenance 5.2 Installation of the Modules Installation on a mounting plate Unscrew the 3 screws on the right side of the OLM (the side with the type label). Fix with this screws the mounting plate (MLFB: 6GK1503-8AA00). Now fix the OLM at the wall or at a cubicle plate. Make sure there is a reliable and permanent electrical connection between the mounting plate and surface, for example by using toothed washers.

Installation and Maintenance 5.3 Connection of the Electrical RS-485 Bus Cables Only use shielded twisted pair for the RS-485 bus cables as described in the manual “SIMATIC NET PROFIBUS Networks”. Do not exceed the segment lengths specified there. Connect the RS-485 bus segment via a PROFIBUS connector. If the module is at the beginning or at the end of a bus segment, this connector must have an active bus terminator.
Installation and Maintenance 5.4 Connecting of the Operating Power Supply 5.4 Connecting of the Operating Power Supply L1+ The terminal block can be removed from the device to allow cables to be connected. F1 M F2 L2+ Figure 5-8 5.5 Operating power supply, pin assignment 5-pin terminal block Supply the module only with a stabilized safety extra-low voltage of a maximum of +32 V (typically +24 V) according to IEC 950 / EN 60 950 / VDE 0805.
Installation and Maintenance 5.6 Receive Level of the Optical Channels 5.6 Receive Level of the Optical Channels The receive level of the two optical channels CH2 und CH3 can be measured using a standard voltmeter via the measurement sockets. The voltmeter can be connected and disconnected while the device is operating. The OLM is protected against a short circuit at the measurement sockets; data transmission is not influenced.
Installation and Maintenance 5.7 LED Displays and Troubleshooting Notes: For a valid measurement, that the partner OLM at the other end of the fiber-optic cable must send normal PROFIBUS frames. This can be recognized by the LED display of the partner OLM (see section 5.7.1).

Installation and Maintenance 5.8 Maintenance 2. Detect the optical receive level (section 5.6): Check the fiber-optic cable attenuation with an optical level meter if the level is in the range “function not guaranteed” or “optical link power margin reduced". If the attenuation is too high, replace the fiber-optic cable. If the attenuation is within the valid range, one of the two OLMs of the disturbed segment is defective.
Installation and Maintenance 5.9 Cleaning 5.9 Cleaning If it becomes necessary to clean the device, this must be done with a dry, lint-free cloth. Do not use water or solvent! If liquids get into the device, it must be deactivated. When cleaning the device, make sure that no dirt enters the optical transmission path or gets onto the optical components. This means either that the fiber-optic cables remain connected or you fit the supplied protective caps! 5.
