Understanding HMI programming and development
HMI programming involves the creation of the visual representation (graphic) of the machine operation, control commands, and writing codes to execute required functions.
The main purpose of an HMI is to allow the operator to control a machine or process. Hence, an HMI design must do the following:
- Be easy for the user to have access to the necessary information and control.
- Allow the user to navigate to different areas as quickly as possible.
- Allow the user or operator to see the current status of the machine. The operator must be able to tell whether the machine is running or has stopped through visual indication on the HMI. Other information that can help the operator to make the right decision can also be provided.
Let’s proceed to learn about HMI programming software in the next section.
