Finding the way up to the standardization of Human Machine Interface

We can find any optimistic or pessimistic arguments to justify the Human Machine Interface (HMI) standardization as a good idea. After standards for process equipment, sensors, actuators, PLC’s, process automation, fieldbus, it is logical to standardize HMI. Nevertheless, it seems finding the way to standardize HMI is a long way. Since mid-80’s lots of suppliers and customers defined their own standards, some of them are no longer current with today’s environments, but still in operation. HMI’s are used on such a variety of machines in such a variety of industries that it is a challenge to find a standard that cuts across all areas. Even restricted to process industries, it isn’t simpler anymore because HMI’s is the mirror of the process and interacting with the organization. It will be challenging to determine the way and the scope of HMI’s standardization, for example ; classes of industries, classes of process, operation organization, operation documents, last but not the least, technological supports. This presentation is restricted to energy HMI’s.
