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 (D 32, D 3'2 ) transmitted by human-machine interface ( 3, 3 ') and at least second status information (D 12 ) transmitted by device control unit ( 1 ); processing first status information data (D 32, D 3'2 ) and second status information (D 12 ) for generating at least third (D 23, D 23 ') and fourth (D 21 ) status information available for human-machine interface ( 3, 3 ') and device control unit ( 1 ); broadcasting third status information (D 23, D 23 ') to human-machine interface ( 3, 3 '); and broadcasting fourth status information (D 21 ) to at least one device control unit ( 1 ).
