In an aircraft load management center each LRU is addressed by a separate line. Power control units on an LRU are addressed by a bus to which all the LRUs are connected in parallel. Control and status inputs, and status output lines are connected in parallel to the LRUs. A programmable logic unit on each LRU decodes the controller addresses, couples control and status request inputs to the controller. The load management center automatically connects a status signal to the interface output after each control function input.
