PROFIBUS PA to Fibre Optics (PROFIBUS PA OLM)

Image
We’ve been receiving numerous requests for converting PROFIBUS PA to fibre optics lately.  I believe that really what the request is that there is an existing PROFIBUS DP master with DP (and possible existing PA) infrastructure and the requirement is to add some PA devices that are out in the field. PROCENTEC have a range of COMbricks modules that are able to meet almost ant type of network configuration. In this article we'll investigate some of the configuration options and which components should be used in each configuration. Your network layout might look something like the picture below: 




Being able to run fibre to these field areas has the following advantages:
Fibre can be run over longer distances, PROCENTEC offer up to 30km on single-mode fibre. Typically, 2km on multi-mode. Fibre can run through areas that are susceptible to EMC interference without being affectedThe inherent electrical isolation means that the complicated story of earthing on PA systems is simplified to …
