hii everybody, i have 2 compactlogix L32E and two devicenet scanner for pumps control and i want to use redundency between them ,i'm a bigginer i tried but until now i can't do it ,so any body can help me please
The principal Redundant control system offered by Rockwell Automation is ControlLogix Redundancy. It uses ControlLogix (1756-L6x) controllers and ControlNet for I/O networking.
There is a DeviceNet-based "Easy Backup" mechanism for CompactLogix that provides a "hot standby" controller. It lacks many of the redundancy features that ControlLogix Redundancy provides, such as media redundancy, scan synchronization, data table cross-loading, and program edit cross-loading.
ControlLogix Redundancy is described in the ControlLogix Redundancy System User Manual, 1756-UM523. You must read and understand that manual and the Redundancy firmware release notes before attempting to implement ControlLogix redundancy.
hiii ,thanks for ur advice it work redundancy with 2 compactlogix and devicenet scanner ,but when i used factory talk for supervising i can't conect to one processor ,so if u have any idea about changing IP adress when the CPU change so factory talk connect with only the one who work thank you
