Abstract
The invention describes an interface device for controlling data exchanges between a central unit and a plurality of satellite units each having an operative cycle of its own, without any chronometric relation imposed to the said units. Said interface device comprises an addressable arrangement memorizing a record of the timed sequence of the steps of each one of the operative cycles of the satellite units and an executer circuit which, on request from the central unit, sequentially scans the record of the operative cycle of the addressed satellite unit and applies to a command input of the said unit the actuation commands derived therefrom at an asynchronous timing of the steps of the said operative cycle record.
