DP master
A
master that operates in accordance with IEC 61784-1:2002 Ed1 CP 3/1 is
referred to as a DP master.
DP-Norm
The DP standard is the bus protocol of the ET 200S distributed I/O system in
accordance with IEC 61784-1:2002 Ed1 CP 3/1.
DP slave
A
slave that operates on PROFIBUS with the PROFIBUS-DP protocol and
functions in accordance with IEC 61784-1:2002 Ed1 CP 3/1 is called a DP slave.
ET 200eco
Distributed I/O station for modular for I/O installation.
ECOFAST
Energy and Communication Field Installation System) Refers to a system for
distributed and modular installation as well as comprehensive diagnostics on
component level.
Equipotential bonding
Refers to an electrical connection (equipotential bonding conductor) that keeps
electrical equipment and extraneous conductive objects to the same or almost
the same potential in order to prevent disturbing or hazardous voltages between
these objects.

Diagnostics
Floating
The reference potential for the control and load circuits of floating–potential I/O
modules is galvanically isolated; e.g. via optocoupler, relay or transformer. I/O
circuits can be connected to the same source potential.
Ground
Refers to conductive ground, with arbitrary zero point of the electrical potential.
In the vicinity of grounding elements, the ground may have a potential other than
zero. For this reason, the term ”reference ground” is often used.
