Summary:PROBLEM TO BE SOLVED: To provide a fault-tolerant computer-controlled system capable of facilitating implementation, analysis and a test, and of holding down failure risk. SOLUTION: This error-tolerant computer-controlled system is provided with a plurality of computers P0, P1 and P2 redundantly functioning for controlling actuators A0, A1 and A2 based on signals from sensors S0, S1 and S2 and input devices V0 and V1. Data items transmitted from the respective computers are simultaneously transmitted to the respective actuators via communication paths different from one another, and the respective actuators receives the respective data items via a plurality of the paths in a normal operation. The system continues to properly function without needing to change the route of the data item even in a failure, facilitates design, analysis and a test, and thereby enhances reliability.
