SYSTEM FOR MONITORING A STATUS DISPLAY

摘要

A system for monitoring a status display (ZANZ) comprises a display controller (ASE), a monitoring unit (UWE) and a system control unit (SSE). The display controller (ASE) is designed to control the status display (ZANZ), depending on a status for display (AZ), which may be supplied to the display controller (ASE) by the system control unit (SSE) via a first interface (S1). The monitoring unit (UWE) is designed to record a current displayed status (AAZ) on the status display (ZANZ) and to provide the same at a second interface (S2) for the system control unit (SSE). The monitoring unit (UWE) is designed to monitor a given activity of the display controller (ASE) and and to switch off the status display (ZANZ) on determining an error or an error in the given activity. The system control unit (SSE) is designed to compare the received current displayed status (AAZ) with the transmitted status for display (AZ) and to control the status display (ZANZ) for switching off the status display (ZANZ) on determining a difference.
