1 Introduction
The PROFIBUS OLM (Optical Link Module) product family consists of
OLM/P11,
OLM/P12,
OLM/G11,
OLM/G12,
OLM/G12-EEC,
OLM/G11-1300
and
OLM/G12-1300.
PROFIBUS OLMs are designed to be used in optical PROFIBUS field bus networks. They enable electrical PROFIBUS
interfaces (RS 485 level) to be converted into optical PROFIBUS interfaces and vice-versa.
By profiting from the familiar advantages of optical transmission technology, the modules can be integrated into
existing PROFIBUS field bus networks. A complete PROFIBUS field bus network with modules in line, star or ring
topology, and an arbitrary combination of these, can also be built up.
The redundant ring is also supported, thereby increasing the fail-safety of the field bus network.
Each module has two or three mutually independent ports, which in turn consist of a transmitting and a receiving
component.
The device is powered by 24V DC voltage. A redundant feed increases operational safety.
The electric port is a 9-pole Sub-D socket (female). An RS 485 bus segment in line with the PROFIBUS standard
EN 50170 can be connected to this port.
The optical fibers are connected using BFOC

/2.5 connectors.
Four multicolored light-emitting diodes indicate the current operating status and possible operating malfunctions.
