Abstract

A multi-channel control system includes a first primary control microprocessor and a second primary control microprocessor operable to control a device, and a first secondary control microprocessor and a second secondary control microprocessor operable to control the device. Each of the first and second primary control microprocessors and the first and second secondary control microprocessors are arranged as an independent control channel.
