Glossary
function groups via interfaces as well as the generation of group indications are important for this bringing
together.
General Interrogation
The state of all process inputs, of the status, and of the error image are scanned on system startup. This infor-
mation is used to update the system-side process image. Likewise, the current process state can be interro-
gated after data loss with a general interrogation (GI).

Ground
The conductive ground whose electric potential can be set equal to 0 at every point. In the area of grounding
conductors, the ground can have a potential diverging from 0. The term reference ground is also used for
this situation.
Grounding
The grounding is the entirety of all means and measuring for grounding.

List view
The right area of the project window displays the names and symbols of the objects which are within a
container selected in the tree view. As the visualization is in the form of a list, this area is also referred to as list
view.
Metered value
Metered values are a processing function, used to determine the total number of discrete similar events
(counting pulses), for example, as integral over a time span. In the power supply utility field, electrical energy
is often recorded as a metered value (energy import/delivery, energy transport).
Navigation window
Left area of the project window, which visualizes the names and symbols of all containers of a project in the
form of a hierarchical tree structure.
Offline
If there is no communication connection between a PC program (for example, configuration program) and a
runtime application (for example, a PC application), the PC program is offline. The PC program executes in
Offline mode.
Online
If there is a communication connection between a PC program (for example, configuration program) and a
runtime application (for example, a PC application), the PC program is online. The PC program executes in
Online mode.
