Page 9: Introduction
Introduction 2.1 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) or three (OLM P12, G12) 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...

Page 13: Network Topologies
Network Topologies 2.1 Introduction 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. -

You can avoid this error message by setting unused channels to the mode “bus without fiber-optic link monitoring”.

Installation and Maintenance 5.1 Installation Installation and Maintenance 5.1 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 34: Figure 5-2 Securing Shielded Cables With Cable Clamps And Cable Retainers
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. - Page 35 Installation and Maintenance 5.1 Installation surfaces are ideal for good contact between grounding elements. With tin- plated surfaces, the necessary contact must be established using screws. Painted or varnished surfaces at the contact points are unsuitable. Shield clamps or contacts must not be used as strain relief.
