Redundant Controllers with BC810, but not redundant modules on CEX
In the attached figure from ABB manual, how would the non-redundant CEX modules be positioned in the hardware tree?
Assuming the upper controller is primary, numbered from RIGHT to LEFT on the Primary controller, the module positions are 1, 2, 3, and 4 (module with TB850).
Would the positions be on the modules connected to the lower controller 7 for the module connected to the controller, 8 for the middle, and 9 for the module with the TB850 connected to it?
Could the first three modules connected to each controller be configured as redundant modules as the modules on the top and the bottom are the same and the fourth module on top be configure as a non-redundant module?
Could you make the 2 and 3 modules on the upper redundant and the furthest left modules on lower redundant?
To my knowledge:
I think that you have to pair redundancy (obviously the same module type), with each other from right to left as you pointed out.
And you are correct regarding designation, first module on lower is nr 7.
In this example you could set redundancy for first pair: module 1(7), leave upper module 2 non-redundant, set next redundant pair: 3(8) etc.
