Glossary
Configuration software
The configuration software is used to create projects for process visualization.
WinCC flexible is such a configuration software, for example.
Display duration
Defines whether a system alarm is displayed on the HMI device and the duration of the
display.
EMC
Electromagnetic compatibility is the ability of electrical equipment to function properly in its
electromagnetic environment without influencing this environment.
Event
Incoming events trigger defined functions. 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 those keys are defined in the engineering phase. The function key assignment
can be specific to an active screen or not.
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.
HMI device
HMI devices are used to operate and monitor machinery 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 enable intervention in machine or plant processes and
sequences.
