<p>Electrical equipment has its components mounted on a plurality of circuit cards. The communication to and from the cards, the supply of supply voltages, etc., take place via conductors arranged on a connection device. The circuit cards are connected to the conductors by means of contact devices. At least some of the conductors are interrupted at each contact device on the connection device. Some of the cards, are slave cards, and are provided with means for bridging the interruptions, whereas others, the main cards, have no such bridging means. By plugging an optional number of slave cards into the connection device immediately adjacent to a main card, a functional unit is formed at an arbitrary location on the connection device. The conductors provided with interruptions form a local bus for internal communication within a multi-card functional unit.</p> |
