Event
Functions are triggered by defined incoming events. Events can be configured. Events which
can be assigned to a button include "Press" and "Release", for example.
Field
Area reserved in configured screens for the input and output of values.
Flash memory
Flash memory is a non-volatile memory with EEPROM chips that is implemented either as
mobile storage medium, or as permanently installed memory module on the motherboard.
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
Output of the screen content to a printer.
HMI device
An HMI device is a device used for the operation and monitoring of machines and systems.
The machine or system 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 system.
HMI device image
The HMI device image is a file that can be transferred from the configuration 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.
