First Claim
1. A diagnostic device for operating situations in at least one communication network having of a bus with N wires, wherein N≧
- 1, characterized in that the diagnostic device comprises;
i) P connection means, wherein P≧
N, suitable to be connected in parallel respectively at least to said N wires of the bus to access P available voltages,ii) conversion means arranged for converting said P voltages in P first digital signals (S1(p,t)),iii) processing means arranged for forming a measurement vector (V(t)) associated with a measurement time (t) of the voltages and comprising K elements selected among at least said P first digital signals (S1(p,t)), then for comparing at least said measurement vector (V(t)) with at least I pairs, wherein I≧
1, of the first (Vr1(i,t)) and second (Vr2(i,t)) reference vectors comprising K elements and representative of K minimum and maximum values that can be assumed by the K elements of said measurement vector (V(t)), in order to deliver I second signals (S2(i)) each representative of the result of the comparison, whereby each result is representative of an operating situation on said bus, andiv) I display means each arranged for signaling an operating situation represented by a second delivered signal (S2(i)).

Abstract
A device (D) is dedicated to the diagnosis of operating situations) in at least one communication network (RC) having a bus (BU) with N wire(s). This device (D) comprises i) P connection means (MCI-MC3), with P≧N, bypass-connected at least to the N wires of the bus (BU) so as to access the P voltages présent, ii) conversion means (MV1-MV3) devised so as to convert the P voltages into P first digital signais (SI (p,t)), iii) processing means (MT) devised so as to construct a measurement vector (V(t)) associated with a voltages measurement instant (t) and comprising K éléments chosen from among at least the P first digital signais (SI (p, t)), then to compare at least this measurement vector (V(t)) with at least I pairs, with I≧1, of first (Vt(i,t)) and second (Vr
