hey guys! i was wondering why did profibus adopted the master-slave exchange of data? it is the most efficient way?
For example if i had a profibus-dp network with 5 stations (pc + 2 master + 2 slaves) all connected and with the termination resistors on at the end of the segment:
What happens if some of the slaves devices turns off (say plc s7-200 shutdown)? this will interrupt the bus? I have read the profibus profiles and understand that is always a linear bus topology with token ring media access control, so if some trouble appears in any station obviously(because of linear bus) the bus will fail!......am i correct?
How can i solve that? Did the master-slave method ensures some kind of safety data?
Cheers to all!
