摘要：
The invention relates to a device (D) that is dedicated to detecting operational defect(s) in at least one communication network (CN) having access to a bus (BU). Said device (D) includes: i) connection means (CM1) capable of being connected onto the bus (BU) with a bypass to access the voltages (V1, V2) therein; ii) detection means (DM) arranged to analyze said voltages (V1, V2) to deliver a first signal (S1) representative of the presence of data in the network (CN) and a second signal (S2) representative of the operating status of the network (CN); iii) processing means (MT1) arranged to output, from first (S1) and/or second (S2) signals and/or third signals (S3
11 -S3
22 ), each representative of a comparison result between one of the voltages (V1, V2) and at least one reference voltage, at least a fourth signal (S4
1 -S4
6 ) representative of a defect or of an absence of defects; and v) display means (DM1) arranged to signal each operational defect or absence of operational defects represented by a fourth output signal (S4
1 S4
6 ).
