First of all let me explain - 6RA70 is DC-Master, to control DC-motors - 6SE70 is Masterdrives, to control 3ph. motors You say redundancy ! You are talking about a Simatic H-system with 2 redundant CPUs !? A redundancy like using ET200 is not possible with drives. A possible solution is described in that FAQ. It uses 2 Profibus-boards, each connected to one of the CPUs. The Masterdrives example can be transformed to DC-Master, too. Most of the profibus-parameters "0abc"in Masterdrives are "2abc" in DC-master; let's say: no. of parameter is +2000. http://support.automation.siemens.com/WW/view/en/6945631 Another solution is to connect the drives behind an Y-link. |
