Modular HMI Solutions (STM6)
Harmony STM6 modular HMI panels are designed for flexible machine integration. Built with a separate display and rear module, STM6 allows for easier installation, maintenance, and system customization. With 22mm pushbutton-style mounting, STM6 simplifies panel design while reducing installation time and errors. It can also be deployed as a faceless HMI using a gateway or Edge Box for applications that don’t require a dedicated screen.

Common questions about Harmony HMI panels, software, and selection.
EcoStruxure Operator Terminal Expert Basic supports Harmony ST6, STM6, and select STO models. Compatibility depends on the specific HMI model and software version.
The Basic license supports standard HMI configuration and visualization, while the Professional license includes advanced features like compound object editing and expanded customization.
The battery kit part number for the Harmony HMISTO7xx family is typically HMIZBAT, but compatibility should be confirmed based on the exact model.
Harmony ST6 HMIs offer high-resolution displays designed for clear visibility in industrial environments. Brightness levels vary depending on the model and screen size.
Projects can be transferred using USB, Ethernet, or directly through the EcoStruxure Operator Terminal Expert software, depending on system configuration.
ST6 panels are designed for standard machine applications with larger displays and more functionality, while STO panels are compact 4.3" HMIs built for simple machines and limited panel space.
Yes. Many Harmony HMI models support remote monitoring and control through web-based tools and secure connectivity, depending on the configuration.
Harmony HMI systems are used across manufacturing, food and beverage, automotive, material handling, and water and wastewater applications.
Selection depends on screen size, communication requirements, environment, and system complexity. Province Electric Supply can help match the right HMI to your needs.
