The BusRail is fitted into a 35 mm DIN rail and provides
internal electrical connection between the CPU & Power Modules
and the I/O modules. The BusRail is built up in a passive way.
It consists of the internal data bus, the PowerBus and the
address circuits for the I/O modules. The internal bus is
built up with redundancy. By design the PowerBus has extremely
high availability.
