4 Function description
}The backplane is used for communication between the head module and the electronic
modules and forms the carrier unit for the electronic modules. Communication also
takes place when some slots on a backplane are unoccupied.
}The module can be used to interrupt the periphery supply and to form new supply
groups.
4.1 Supply groups
For potential isolation, the supply (Periphery Supply) of the upstream (left-hand) modules
on the backplane is interrupted and is refreshed for the downstream (right-hand) modules
at a supply voltage module.
Supply group 1 Supply group 2 Supply group 3
