Human Machine Interface (HMI) has become one of the essentials of modern industrial automation systems. HMI is a display on touch-sensitive screens that connects a person to a machine. Even though Programable Logic Controls (PLC) often run behind the scenes without a screen displaying, an HMI allows the PLC to visually display what it is doing or has done. These HMI displays are often driven through an Ethernet connection by PLC programs, commonly used in industrial processes; such as, oil and gas, manufacturing, material handling, robotics, and food processing. This course introduces the fundamentals of HMI, including symbology and programming techniques. The student will write, configure, upload, and run HMI programs using HMI software.
