Hello Adi_EA ID it seems you really will have to deliberately create spurlines and as Daniel already said, they are ideally avoided all together in a Profibus installation (and quite rightly so as far as I'm concerned). As such I wonder if usage of the so called ProfiHub from Procentec is worth your while considering for your application. AProfiHub is - in simple terms -nothing else but a bunch of 5 repeaters put intoone package. It has been around for some years,I've personally used it numerous times andit works like a treat(Disclaimer: The company I work for are distributors for Procentec gear, just to get the "conflict of interest" notice out with this advise). You'd use it in your case to have one device (e.g. Simocode) connectedper channel and elimate all your spurlines problems (every channel is fully "repeated' and can have up to 31 devices connected to it. While yourinstalltion may look like it has plenty of spurlines, it has in fact none). Anyway, food for thought and I hope it helps. |
Cheers |
