Where is the HMI project stored?

The HMI project is stored in the HMI memory because this is where the graphical user interface and the control logic for the HMI are kept for active use. The HMI memory allows for rapid access to project files necessary for functioning, allowing operators to interact with the system in real-time. This storage method ensures that the HMI can execute its software efficiently, facilitating the display of data and control commands to the user.

While external hard drives and cloud servers are potential storage locations for backups or development files, they do not provide the direct and immediate access required during HMI operation. Similarly, the PLC database is typically used for storing process control data rather than HMI project files. Therefore, keeping the project stored directly in the HMI memory is essential for optimal performance and functionality.
