Im curious as to how other people handle redundancy requirements. I'm currently working on a project with rundandant compact logic processors and 4 devicent scanners. Two scanners are setup as primary and secondary on the same network. The other two are setup the same way. Every time an output is turned on we fire 2 rendundant relays controlling the same device. They also have a graphic panel that has a backup touchscreen.
We actually had an Allen Bradley rep tell the customer they have overcomplicated the system so much their reliability has gone down.
My personal preference is to just provide spare parts that can be plug and play. I almost always feel that most rendundant systems end up more headache than they are worth.
