Abstract: The invention relates to a device for monitoring the operation of an industrial installation (3) comprising functional members (5), the said device (1) comprising groups (G1, G2 . . . Gn) of detectors (D1,1, . . . Dn,j) that defect the operating status of the installation (3) these each being associated with a particular aspect of the monitoring, and a display unit (11) comprising means (13) of communicating the operating statuses picked up by the said detectors (D1,1, . . . Dn,j). The device comprises, arranged between the said detectors (D1,1, . . . Dn,j) and the display unit (11), means (15) for processing the operating statuses picked up by the said detectors (D1,1, . . . Dn,j) and for controlling the selective displaying, on the said display unit (11), of information relating to overall operating statuses of predetermined groups (G1, G2 . . . Gn) of detectors (D1,1, . . . Dn,j).
