Abstract :
This paper studies an implementation of the multiple-task triple modular redundancy (MTTMR) technique applied to a scenario involving a controlling application in an automobile factory. Active replication, namely triple modular redundancy (TMR), is used to tolerate faults in the controlling application. The manufacturing message specification (MMS) is used as a communication protocol between the controlling application and remote devices in the factory. We show how MTTMR improves the system´s performance and continues to guarantee the fault tolerance of the TMR technique
