3.3.5 Fibre-optical waveguide
We recommend fibre-optical waveguide technology for trans-
mission in areas which are subjected to heavy interference,
as well as for extending the range of transmission with high
baud rates.
This offers the following extra advantages:
– high degree of EMC compatibility, ESD protection due to
the optical transmission of the signals
– protection against lightning
– potential isolation of the individual DP slaves
The PROFIBUS-DP interface of the Local control unit has been
designed in accordance with specification EN 50170 volume 2
and therefore supports the control of network components
for fibre-optical waveguides.
Examples of fibre-optical waveguide network components:
– Siemens optical link module (OLM) for PROFIBUS plus
– Siemens optical link plug (OLP) for PROFIBUS
