Page 9: Introduction
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. -
Page 10: Table 2-1 Number Of Electrical And Optical Ports Per Module
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. - Page 11 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. They only differ in the specification of the ambient climatic conditions: the OLM / G12 is suitable for use in the standard temperature range from 0 °C to 60 °C, whereas the OLM / G12-EEC (extended environmental conditions) can be used in the extended temperature range of -25 °C to +60...

Page 13: Network Topologies
Network Topologies 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. -
Page 14: Linear (Bus) Topology
Network Topologies 3.1 Linear (bus) Topology 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. -
Page 15: Linear (Bus) Topology With Fiber-Optic Link Monitoring And Segmentation
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. -

Page 17: Ring Topology
Network Topologies 3.3 Ring Topology Note: Unused optical channels you intend to use later to expand the network cause a broken fiber- optic 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. - Page 18 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.

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.

Page 35: Installation And Maintenance
Installation and Maintenance 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. - Page 36 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.
