    Abstract: The device comprises three linkage zones: zone I consisting of a connection network, terminating equipment, detectors/transmitters of local, remote information, zone II consisting of miniprocessors connected to the units of zone I and programmed independently, zone III consisting of a central processor and a maintenance processor each associated with a memory, and each connected to the miniprocessors of zone II. The exchanging of messages between the central processor (PC) or the maintenance processor (PM) of zone III and the front-end miniprocessors (MPF1 to MPF4) of zone II is carried out by way of couplers built into the processors and the miniprocessors, each coupler being connected to a silo bus, bs1 or bs2. Each front-end miniprocessor includes a front-end dialogue coupler (CFD1) connected to a central dialogue coupler (CCD1) of the central processor, and a front-end dialogue coupler (CFD2) connected to a central dialogue coupler (CCD2) of the maintenance processor. Each coupler, front-end or central, includes suitable software allowing information exchanges carried out by direct memory access at processor level, and by word by word programmed mode at front-end miniprocessor level. Dialogue between the central processor and the front-end miniprocessors is undertaken by exchanging messages composed of a maximum of 16 words of 16 bits.
