Function key
Function keys on the HMI device can be assigned user-specific functions. The functions
assigned to these keys are defined during configuration. The assignment of the function keys
may be specific to an active screen or independent of it.
Half Brightness Life Time
Time period after which brightness is reduced to 50% of the original value. The specified
value depends on the operating temperature.
Hardcopy

HMI device
An HMI device is a device used for the operation and monitoring of machines and plants.
The machine or plant states are visualized on the HMI device by means of graphic objects or
signal lamps. The operator controls of the HMI device allow the operator to interact with the
processes of the machine or plant.
HMI device image
The HMI device image is a file that can be transferred from the configuring PC to the HMI
device. The HMI device image contains the operating system for the HMI device and the
elements of the runtime software required to run a project.
I/O field
An I/O field enables the input or output of values on the HMI device which are transferred to
the PLC.
Infotext
An infotext is a configured information on objects within a project. Infotext for an alarm, for
example, may contain information on the cause of the fault and troubleshooting routines.
Object
An object is a project element such as a screen or an alarm. Objects are used to view or
enter texts and values on the HMI device.
Operating element
An operating element is a component of a project used to enter values and trigger functions.
A button, for example, is an operating element.
