OPERATION CONTROL SYSTEM AND OPERATION APPARATUS FOR CONTROLING REAL-TIME ERROR

PURPOSE: An operation control system for controlling real-time errors and a device thereof are provided to enable a second operation device to check errors of the output data of a first operation device and to display the output data of the second operation device, thereby rapidly outputting error-free data. CONSTITUTION: First and second operation devices (200,300) execute multiple operations for input data. The first and second operation devices select one of operation data, which is generated by the multiple operations, as first result data. The first operation device generates a first output message including the first result data. The second operation device checks the error of the first operation device by using the first output message. An output device (400) selectively outputs the first result data and the second result data according to errors.
