I suspect on profibus lines cabling and termination, else redundant controller will not toggle...
Check this thread regarding cabling and terminations @ http://www402.abbext.com/Can-configure-profibus-line-redundancy-AC900F-q1691891
Also check answer from manisampath in this thread linked herewith @
Also didn't get you on "Even I tried by configuration of Stand Alone controller also but results same.As I enable Profibus Line Redundancy Both Controller and CI start switching" If it's stand alone controller how it can switch ? or do you mean redundant single controller ?
