Abstract:
In a circuit for synchronized interchange of data between different locally dedicated signal sources of a distributed configuration wherein each signal source is provided with an allocated controller, the improvement comprising:a) a single synchronous serial bus with timing information implemented in the bus standard protocol comprising a link for bi-directional serial multi-channel data interchange between said signal source controllers and/or a data extracting unit;b) said single synchronously operated serial bus is operated for synchronized data exchange between a plurality of intelligent sensors or servers and one master controller in an operational mode and in a command mode;c) said master controller is controlled in said operational mode so that data exchange between said master controller and at least one of said sensors is initiated and completed over two time frames; andd) each of said frames is formed of groups of a same plurality of bytes so that a specific instrument address placed in a specific byte position by said master controller is followed by a defined number of byte positions reserved for sensor response information from an instrument addressed during the previous frame.
