EMC
Electromagnetic compatibility (EMC) refers to a usually desirable state, in which technical
equipment does not disturb one another with unwanted electrical or electromagnetic effects.
Electromagnetic compatibility deals with technical and regulatory questions of undesired,
mutual influence in electrical engineering.
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.
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
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.
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 configuration PC or from an
external storage medium to the HMI device. The HMI device image contains the operating
system for the HMI device and the elements of the runtime software which are required to
start and visualize the project file.
Input box
Use the input box to enter characters and values that are stored in the HMI device or
transferred to the controller.
Job mail
A job mail triggers a function for the controller on the HMI device.
