Hello 
I'm Kasem, Mechatronics Engineer

I'm going to connect UR3e robots to Beckhoff PLC  over Profinet , I used CAT 5e Ethernet cable while testing and it worked fine but the distance was short around 3 meters 
I want to use professional Standard  reliable Profinet Cables to support max communication speed , but i don't know what type of Profinet does UR support A or B or C 
as in this link the cables differ based on the Profinet type https://www.belden.com/products/industrial/cable/ethernet/cat5e-profinet

Could somebody please let me know if they used profinet cables with UR , what type and recommendation for reliable and high speed cables brands 

Thank you
