Abstract
The invention relates to an arrangement for testing a watchdog circuit wherein the pulses of a microcomputer to be monitored by the watchdog circuit are incrementally lengthened until the watchdog circuit responds and emits a corresponding reset signal to the microcomputer. The operational test of the watchdog circuit is repeated after each cold start of the microcomputer. This arrangement is especially suited for systems relevant to safety wherein the functional reliability of the individual components such as microcomputer and actuating elements are to be monitored.
