Abstract
A vital communication system includes a conventional, that is non-vital, communication link, a transmitter and a receiver. The transmitter is responsive to input data, and provides for encoding and transmission as well as checking of its own input arrangement. The encoding and transmission is effected by a program driven device, but as loaded the program is incomplete. The checking produces certain check words which are used to complete the program so that only in those instances in which the checks are passed, will an appropriate message be transmitted. The receiver includes a decoder logic as well as a decoder check logic. The messages are decoded and applied to an output device. The decoder check logic checks that the information supplied to the output device corresponds to the decoded information, and if the check is passed, the output device is enabled to output the information to the outside world.
