1. A human machine interface (HMI) device, comprising:
- a power recognition component that determines one or more power sources that are providing power to the HMI device, the one or more power sources are one or more of a host device providing power by way of a Universal Serial Bus connection, an AC power source, a DC power source, or a battery; and
a selector component that automatically selects a subset of functionalities to enable with respect to the HMI device from amongst a plurality of possible functionalities based at least in part upon the determined one or more power sources providing power to the HMI device, the plurality of possible functionalities including at least a web server function that configures the HMI device to serve web pages to a host device, a backlight function that powers backlighting for an interface associated with the HMI device, and a maintenance function that enables installation and configuration of an HMI application.

Abstract
A human machine interface (HMI) device comprises a power recognition component that determines at least one power source that is providing power to the HMI device, wherein the at least one power source is one of a host device providing power by way of a Universal Serial Bus connection, an AC power source, a DC power source, and a battery. A selector component can automatically select a subset of functionalities to enable with respect to the HMI from amongst several possible functionalities based at least in part upon the at least one determined power source.

15. A method for configuring a human machine interface (HMI) device, comprising:
-
identifying one or more power sources providing power to the HMI device, the one or more power sources being at least one of a host device that provides power to the HMI device by way of a USB, an AC power source, a DC power source, or a battery; and selectively enabling at least one functionality of the HMI device from a set of selectable functionalities based at least in part upon the identification of the one or more power sources, the set of selectable functionalities including at least a web server functionality that configures the HMI device to serve web pages to a host device, a backlighting functionality that enables a backlight for an interface associated with the HMI device, and a maintenance function that enables installation and configuration of an HMI application on the HMI device. - View Dependent Claims (16, 17, 18, 19, 20)

21. A human machine interface (HMI) device, comprising:
-
means for identifying which of a universal serial bus (USB) connected host device, an AC power source, a DC power source, or a battery is providing power to the HMI device; and means for selectively enabling, based at least on the identification, at least one function from a set of available HMI functions, the set of available HMI functions including at least a web server function that configures the HMI device to serve web pages to a host device, a backlighting functional that enables a backlight for an interface associated with the HMI device, and a maintenance functionality that enables installation and configuration of an HMI application on an HMI device.
