Numerical control installation making it possible to monitor N machine tools each comprising n motors to be monitored in accordance with a desired independent program. The single monitor device (C) comprises a data input station (1), a minicomputer (2), an interface equipment (8) composed of N interface units (8A to 8N) connected by a bus (7) to the minicomputer. Each unit (8A to 8N) is assigned to a machine tool (9A to 9N) and comprises an interface circuit (10) of 2n bits having n sections (10a to 10n) for monitoring each of the n motors (12a to 12n) of a machine. Each machine (10a to 10n) is extended by a monitor integrated circuit (11a to 11n) assigned to each motor for all the comparison operations.
