The use of programmable logic controller (PLC) to solve this problem has a unique advantage in electrical automation applications have broad prospects and great market potential. Relay control system with the traditional, compared to programmable logic controller (PLC) has the advantage of being: the volume of smaller, highly integrated, but also the number of computing, data processing and data communication functions. PLC as a new generation of industrial control devices, simple structure, the performance of a comprehensive, high reliability. This topic is based on the programmable logic controller design of dual-power switch, dual power switch for the automatic switch from the complex, lack of phase and under-voltage...
