Alarm
An alarm may be a system alarm or a user-defined alarm. A user-defined alarm typically
indicates a particular operating state of the plant, a system alarm typically contains
information about the state of the HMI device.
Boot loader
The bootloader is used to start the operating system and is started automatically after the
power on of the HMI device power. The Control Panel opens after the operating system has
loaded.
Configuration PC
A configuration PC is a programming device or PC on which plant projects are created using
engineering software.
Configuration software
Configuration software is used to create projects used for the purpose of process
visualization. WinCC represents such configuration software, for example.
Controller
Controller is a general term for devices and systems with which the HMI device
communicates, for example SIMATIC S7.
Degree of protection
The degree of protection specifies a standard of electronic equipment for a variety of
ambient conditions – and the protection of humans against potential danger when using this
equipment.
The degree of protection classified by IP differs from the protection class. But both involve
protection against touching dangerous electric voltage. The IP degree of protection also
classifies the protection of equipment against dirt and moisture.
Display duration
The display duration defines whether and for how long a message or a dialog box is
displayed on the HMI device.
