Check: All cables OK? Als shields connected in propper way? Resistorswitches in right position and working? NO segment with more 32 Slaves AND NOT longer than 50m without repeater! Have a look here: http://www.indu-sol.com/en/index.html and also search for "Profibus inspector" Last, but not least, shoot the guy who select 12M for this topology. |
