Monitoring computer in a control device
First Claim
1. A monitoring computer for monitoring a processor, on which processor a computing element is executed,wherein the processor essentially comprises a functional computer apart from the monitoring computer,wherein the computing element comprises a functional module, a safety module and a monitoring module, all modules can be executed on the functional computer and the monitoring computer communicates with at least the monitoring module on the functional computer by a dialog method via an interface,wherein the functional computer and the monitoring computer are physically independent of each other and the monitoring computer comprises a first monitoring unit and a second monitoring unit that are independent of each other,wherein for monitoring the proper processing of the program instructions of the functional computer, one check each can be performed in the functional computer by each monitoring unit by a corresponding monitoring element, and wherein a first check can be performed in the safety module of the computing element by the first monitoring unit via the corresponding monitoring element in the corresponding test path and a second check can be performed in the monitoring module of the computing element by the second monitoring unit via the corresponding monitoring element in the corresponding test path.
