I have a cut in profibus cable can i weld it ? 

And the amount of datq is huge

Split from PROFIBUS cable connection solution??.

Welding might not be proper technology to use. Consider soldering.

Take care of proper isolation and shielding of signal wires.

Do not solder data as it may stop flowing.

 if I will be at your side, I'll do this thing what I see better and somehow correct. In place of cut I set on both sides PB connectors, one with PG socket and connect sides together.  easy and nice solution, correct? In case of pure PB cable I see welding/soldering as last and not clear solution. To PB connectors you can also do any cover (shield) if is needed to do that, many IPXX boxes can be used and is easy to install them .

Hello Engs7s;

Basically, any change in cable capacitance will make Profibus transmissions difficut and untrustworthy.

And there is a great risk of modifying the cable capacitance at the soldering or welding point.

The elementary recommendation from Profibus International (PI) would be to run another length of Pofibus cable, to re-establish a consistent connection between Profibus nodes,. If ths is not possible, look at this extract from PI's Profibus installation Guidelines proposes various suggestions to repair a damaged cable:

Hope this helps,
