FF Link Master
A master that behaves in conformity with IEC 61784‑1 CP 1/1 is termed a FOUNDATION
Fieldbus Link Master. The bus link (Compact FF Link) acts as a DP slave for "higher-level"
systems (toward the automation system) and as an FF Link Master for "lower-level" systems
(toward the FF devices).
Field bus
The field bus is a serial bus system for the distributed integration of field devices in an
automation system
Ground
The conductive earth whose electrical potential can be set equal to zero at any point.
Ground refers to the entirety of all interconnected inactive parts of a piece of equipment that
cannot possess a dangerous contact voltage, even in the event of a malfunction.

Ground terminal PE
Name of the connector on electrical equipment in potentially explosive atmospheres that is
wired to the equipotential bonding system.
Grounding
Grounding means connecting an electrically conductive part to a grounding system by means
of the ground electrode.
GSD file
All slave-specific properties are stored in a Device Data Base File (DDBF file). The format of
the DDBF file is to be found in the PROFIBUS guideline: Specification for PROFIBUS Device
Description and Device Integration Vol.1: GSD V4.1, 07/2001 of the PROFIBUS-
Nutzerorganisation (PNO).
H system
High availability system consisting of at least two central modules or two separate devices, for
example PCs (master / reserve). The user program is processed identically in the master and
in the reserve devices.
