Connection with fibre-optic cables (FOC)
The PROFIBUS-DP interface of the bus node corresponds to
the specification EN 50170-2 and supports the control of net-
work components for fibre-optic cables.
Use fibre-optic cables for transmission in environments sub-
ject to heavy interference as well as for extending the working
range at high transmission rates.
Examples for fibre-optic cable network components:
– Siemens Optical Link Module (OLM) for PROFIBUS plus
– Siemens Optical Link Plug (OLP) for PROFIBUS (IP 20)
– Harting Han-InduNet
