Ethernet cable range

plcsoftvsd · Jul 16, 2008

I am in a a bit of fix ..we have a project wherein we are using ethernet cables to connect between 6 PLC's but the distance is 145 metres. ( and i think 100 metres is the maximum length recommemded for ethernet cable).

What could be good economical solution for this problem,

The fibre optic solution is expensive as i need to buy FO switches for all the 6 plcs i need to connect.

cheers.

Economical: Stick a switch in at the halfway point.

Ditto

Done that and it works

Even more economical:
Just connect a 145 metres ethernet cable of good industrial quality (=Profinet). I have done that many times up to 150 metres with never a problem.

Hello Jesper ,

Is this the cable you are mentioning,..if not can you please give me the link.

Cheers.

Yes, that looks like one possible supplier.
I use Siemens myself, but I dont have the exact type number where I am at the moment.

You could just put a converter from Copper to Fibre especially if your runs go outside:
