System for monitoring a status display (ZANZ), which system comprises - a display control unit that comprises a computation unit or is in the form of a computation unit and that is coupled to the status display (ZANZ) and that is designed to actuate the status display (ZANZ) on the basis of a status to be displayed that can be supplied to the display control unit via a first interface, - a monitoring unit that is in the form of a logic circuit operating independently of an operating state of the display control unit and that has its input side coupled to at least one status output (ZAUS) of the status display (ZANZ) and that is designed to sense a currently indicated status of the status display (ZANZ) and to provide the latter on the output side on a second interface and that is coupled to the status display (ZANZ) and is coupled via a third interface to the display control unit and is designed to monitor a prescribed activity of the display control unit and to shut down the status display (ZANZ) if said prescribed activity is found to be absent or to have an error, - a system control unit that is coupled via the first interface to the display control unit for the purpose of sending the status to be indicated to the display control unit and that is coupled via the second interface to the monitoring unit for the purpose of receiving the currently indicated status provided by the monitoring unit and that is designed to compare the received currently indicated status with the sent status to be indicated and to actuate the monitoring unit or the status display (ZANZ) to shut down the status display (ZANZ) if a discrepancy is found. - a display control unit that comprises a computation unit or is in the form of a computation unit and that is coupled to the status display (ZANZ) and that is designed to actuate the status display (ZANZ) on the basis of a status to be displayed that can be supplied to the display control unit via a first interface, - a monitoring unit that is in the form of a logic circuit operating independently of an operating state of the display control unit and that has its input side coupled to at least one status output (ZAUS) of the status display (ZANZ) and that is designed to sense a currently indicated status of the status display (ZANZ) and to provide the latter on the output side on a second interface and that is coupled to the status display (ZANZ) and is coupled via a third interface to the display control unit and is designed to monitor a prescribed activity of the display control unit and to shut down the status display (ZANZ) if said prescribed activity is found to be absent or to have an error, - a system control unit that is coupled via the first interface to the display control unit for the purpose of sending the status to be indicated to the display control unit and that is coupled via the second interface to the monitoring unit for the purpose of receiving the currently indicated status provided by the monitoring unit and that is designed to compare the received currently indicated status with the sent status to be indicated and to actuate the monitoring unit or the status display (ZANZ) to shut down the status display (ZANZ) if a discrepancy is found.
