ÜBERWACHUNGSSYSTEM FÜR DATENVERARBEITUNGSANLAGEN

摘要

Computers located in an unattended room are regularly checked for operational reliability by a monitoring system. A counter (CT) should not reach its end value and must be reset regularly to the initial count of the counter controlled by a monitoring routine (WD) interacting with an execute routine (TR). When resetting is not carried out in time, the computer is restarted or rebooted. When the computer is restarted, a control is carried out to check whether the monitoring system has previously triggered a restart operation. Once a given number of successive restart operations has been reached the computer is set to idle mode. The monitoring system does not require special nonvolatile storage elements.
