EMC Abbreviation for “Electromagnetic Compatibility”. The ability
of electrical equipment to function trouble-free within a
particular environment without a negative effect on the
environment concerned.
EN Abbreviation for “European Norm” or European standard.
Equipotential bonding Adaptation of the electrical level of the body of electrical
equipment and auxiliary conductive bodies by means of an
electrical connection.
ESD Abbreviation for “Electrostatic Discharge”.
Field supply Voltage supply to field devices as well as signal voltage.
Fieldbus Data network on the sensor/actuator level. The fieldbus
interconnects the devices at field level. Characteristic feature
of the fieldbus is their highly reliable transfer of signals and
real-time response.
Galvanic coupling A galvanic coupling occurs when two circuits use the same
cable. Typical sources of interference are, for example,
starting motors, static discharges, clocked devices, and a
potential difference between the housing of components and
the common power supply.
GND Abbreviation for “GROUND” (0 potential).
Ground In electrical engineering the name for conductive grounding
with an electrical potential at any point equal to zero. In the
environment of grounding devices, the electrical ground
potential may not equal zero. This is called a “reference
ground”.
Ground (verb) Represents the connection of an electrically conductive
component to the equipotential earth via a grounding device.
Ground connection One or several components that have a direct and good
contact with the ground.
GSD The device master data files (GSD) contain standardized
PROFIBUS station descriptions. They are used to simplify
the configuration of the DP master and DP slaves.
Hexadecimal Number system with base 16. Counting from 0 to 9 and then
with the letters A, B, C, D, E and F.
