Abstract
A self-checking network is provided, comprising a first command processor configured to execute a performance function and a second command processor configured to execute the performance function, coupled to the first command processor. The self-checking network also comprises a first monitor processor configured to execute a monitor function that is coupled to the first command processor and a second monitor processor configured to execute the monitor function that is coupled to the second command processor. The first and second command processors compare outputs, the first and second monitor processors compare outputs, and the first monitor processor determines whether an output of the first command processor exceeds a first selected limit.
