HMI Challenges in an Industrial IoT World
User interfaces in industrial controls have evolved significantly in recent years. While beginning as dumb terminals, they have moved to touchscreens that can be used on phone and tablet apps. In the world of connected devices in the industrial Internet of Things (IoT), the human machine interface (HMI) becomes particularly challenging. The control engineers want to see all aspects of plant activity-from production to the health of equipment. And they want to see the data from any location on any device.
HMI tools come in a wide range of shapes and sizes, from large control panels to Android or iOS phones. In addition to portability, they feature touchscreen capabilities. (Image source: Schneider Electric)
