Abstract
A verification system monitors the operation of a digital control system in order to insure proper operation. The verification system receives control signals and monitors these control signals to determine whether operation is proper. The digital control system is adapted for operational control of various equipment. The verification system monitors control signals received from the digital control system as well as the status of the equipment, where appropriate, in determining whether the operation of the digital control system is proper. The verification system includes various portions which monitor the control signals at various stages. If there is an error detected at one of the stages, an error signal is generated which prevents operation of the associated equipment.
