A control unit having at least one microprocessor for receiving input data signals from sensors indicative of operating parameters of the at least one system, and for generating first control signals to control operation of said at least one system in response to said input data signals. At least one input/output unit is coupled to receive the input data signals from the sensors in a parallel transmission format and to transmit output control signals to the systems in a parallel transmission format. A backup logic system provides backup control signals when transmission of the control signal is interrupted.
