A powerful HMI is crucial because it simplifies operation procedures and stabilizes operation to increase productivity and decrease errors. A good HMI not only requires great connectivity that supports many kinds of communication methods, but it also needs a wide range of expansion options to apply on different factory automation applications from simple production tasks, product monitoring, to intelligent automation control to ensure system and production procedure functions properly. Moreover, rugged design that supports wide range of temperature, extraordinary performance and reliability are required in order to operate in factory automation.
