Abstract
Abstract A system (10) for connecting sensor devices (11) to actuating devices (12), the system (10) substantially comprising a cable (13) having a given number of signal conducting lines (1, 2, 3, 4, 5), a number of interface units (14,15) each designed for assembly between the lines (1, 2, 3,4, 5) of the aforementioned cable (13) and a respective sensor device (11) or actuating device (12), and processing means (16) designed to circulate, in the aforementioned cable (13), signals (v 2 , v 3 , v 4 ) enabling data to be transmitted between the devices (11) and (12) and the processing means (16).

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
188 words
1) - A system for connecting sensor devices (11) to actuating devices (12), characterised by the fact that it com prises : . at least one cable (13) having a given number of signal conducting lines (1, 2, 3, 4, 5); . a number of interface units (14, 15), each designed for assembly between the lines on the said cable (13) and a respective sensor (11) or actuating (12) device; and . processing means (16) designed to circulate, on a first (2) and second (3) line on the said cable (13), signals (v 2 , v 3 ) cyclically determining connection of each said sensor (11) or actuating (12) device to a third line (4) on the said cable (13) by means of the respective said interface unit (14, 15). for the purpose of respectively supplying to the said third line (4) a signal (v 4 ) depen ding on a parameter detected by the said sensor device (11), or for enabling the said actuating device (12) to receive a control signal (v ) generated by the said sensor device (11) or by the said processing means (16).
Claim 2
Dependent Claim
188 words
1) - A system for connecting sensor devices (11) to actuating devices (12), characterised by the fact that it com prises : . at least one cable (13) having a given number of signal conducting lines (1, 2, 3, 4, 5); . a number of interface units (14, 15), each designed for assembly between the lines on the said cable (13) and a respective sensor (11) or actuating (12) device; and . processing means (16) designed to circulate, on a first (2) and second (3) line on the said cable (13), signals (v 2 , v 3 ) cyclically determining connection of each said sensor (11) or actuating (12) device to a third line (4) on the said cable (13) by means of the respective said interface unit (14, 15). for the purpose of respectively supplying to the said third line (4) a signal (v 4 ) depen ding on a parameter detected by the said sensor device (11), or for enabling the said actuating device (12) to receive a control signal (v ) generated by the said sensor device (11) or by the said processing means (16).
