ABSTRACT:
A communication system interconnecting n slave processors (P1, P2, . . . , Pn) and a master processor (Pn+1) includes a first data communication bus, a second serial signalling bus, which acts as a conduit for a synchronous signalling frame, which consists of time intervals (IT) assigned to the processors, and circuitry for synchronizing the time intervals in the processors. In addition, n first comparing circuits, each associated with one of the slave processors, are provided for detecting the cyclic appearance of the IT assigned thereto. A second comparing circuit associated with the master processor indicates the cyclic appearance of a respective IT.
