System and method of communication by serial communication bus
First Claim
1. System of communication (100) between at least one equipment control module (1) linked to an equipment item (10) and at least one man-machine interface (3, 3′
- ) by means of a serial communication bus (4), characterized in that it further comprises a central computer (2) comprising means suitable for;
receiving at least first status data items (D32, D3′
2) transmitted via the man-machine interface (3, 3′
) and at least second status data items (D12) transmitted by the equipment control module (1);
processing the first (D32, D3′
2) and second (D12) status data items so as to produce at least third (D23, D23′
) and fourth (D21) status data items respectively intended for the man-machine interface (3, 3′
) and for the equipment control module (1);
broadcasting the third status data items (D23, D23′
) to the man-machine interface (3, 3′
); and
broadcasting the fourth status data items (D21) to the equipment control module (1).

Abstract
This invention concerns a communication system (100) between at least one device control unit (10) connected to a device (10) to be controlled and at least one human-machine interface (HMI) through a series communication bus (4). This communication system (100) further includes a central processing unit (2) comprising means for:
receiving at least first status information (D32, D3′2) transmitted by human-machine interface (3, 3′) and at least second status information (D12) transmitted by device control unit (1);
processing first status information data (D32, D3′2) and second status information (D12) for generating at least third (D23, D23′) and fourth (D21) status information available for human-machine interface (3, 3′) and device control unit (1);
broadcasting third status information (D23, D23′) to human-machine interface (3, 3′); and
broadcasting fourth status information (D21) to at least one device control unit (1).
