Guys is anybody running DN on other media types other than those designed for DN use possibly DH+ ?
we have an application on some mutlipurpose overhead gantry cranes in an Aluminium smelter where the cabin & tools rotate 360deg independantly of each other all cabling is via sliprings which are not accessable without major disassembly of the cranes.
originaly Data highway & remote i/o networks are these cranes.
we are going to undertake a PLC upgrade from AB PLC5 to Control logix & are wishing take advantage of DN fuctionality on these machines & remove the DH+ & RIO.
the sliprings installed meet the criteria for DN use other than the cable 3m on each side of the sliprings.
The proposal we have is to install the DN network as per the usual method but use DN-Fibre convertor to fibre patch lead then Fibre-DN convertor onto the DH+ twinax through th sliprings then the same onthe other side.
the use of the fibre-DN will do away with any impedance mismatch as well as provide an electrical insulation level which is bonus.
Your thoughts?
Will it work?
thanx
Scott.
