Programmable adapter device for communication protocoles

摘要

The programmable matching system links an upstream communication protocol and a downstream protocol. An adapter (20) contains a conversion program (15) converting from the upstream protocol to the downstream protocol and may be remotely loadable from the upstream equipment. The programmable matching system links an upstream communication protocol supported by upstream equipment (30), and at least one downstream protocol supported by the downstream automatic equipment (40). It includes an adapter (20) with a first memory (25) containing a conversion program (15) converting from the upstream protocol to the downstream protocol. This is remotely loadable from the upstream equipment, and may be executed by the adapter (20). A second non-volatile memory (26) contains a resident pilot program (16) allowing analysis of the communication with the upstream equipment (30). A further memory zone (17) serves as an intermediate buffer for managing the asynchronism between the protocols. The downstream connection cable (14) allows identification of a complete or partial identifier of the downstream protocol.
