Protection class
The protection class is used in electrical engineering to classify and identify electrical
equipment in relation to existing safety measures designed to prevent electric shock.
There are four protection classes for electrical equipment.
Recipe
A recipe is a combination of tags that form a fixed data structure. The configured data
structure can be assigned data in the configuration software or on the HMI device and is
then referred to as a record. The use of recipes ensures that all data assigned to a data
record is transferred synchronously to the controller.
Runtime software
The runtime software is a process visualization software used to test a project on a
configuration PC.
Screen
A screen is a form of visualization for all logically related process data in a system. The
representation of the process data can be visually supported by graphic objects.
Screen object
A screen object refers to objects such as rectangles, I/O fields or alarm views which are
configured for visualization or operation of the system.
System
General term referring to machines, processing centers, systems and processes which are
operated and monitored on an HMI device.
System event
A system event is assigned to the "System" alarm class. A system event refers to internal
states on the HMI device and the controller.
Tab order
The tab order defined in the course of project engineering determines the sequence for
activating objects by pressing the <TAB> key.
