Ground
Expression used in electrical engineering to describe an area whose electrical potential is equal to zero at any
given point. In neutral grounding devices, the potential is not necessarily zero, and one speaks of the ground
reference.
Ground connection
One or more components that have a good and direct contact to earth.
Ground reference
Potential of ground in a neutral grounding device. Unlike earth whose potential is always zero, it may have a
potential other than zero.
GSD
Acronym for Electronic Device Data Sheet which contains standardized PROFIBUS DP station descriptions. They
simplify the planning of the DP master and slaves. Default language is English.
Hexadecimal
System of representing numbers in base 16 with the digits 0... 9, and further with the letters A, B, C, D, E and F.
Hysteresis
A sensor can get caught up at a certain point, and then “waver“ at this position. This condition results in the
counter content fluctuating around a given value. Should a reference value be within this fluctuating range, then
the relevant output would be turned on and off in rhythm with the fluctuating signal.
I/O
Input/output.
Impedance
Total effective resistance that a component or circuit has for an alternating current at a specific frequency.
Inactive metal components
Conductive components that cannot be touched and are electrically isolated from active metal components by
insulation, but can adopt voltage in the event of a fault.
Inductive coupling
Magnetic inductive couplings occur between two cables through which an electrical current is flowing. The
magnetic effect caused by the electrical currents induces an interference voltage. Typical sources of interference
are for example, transformers, motors, parallel-routed network and HF signal cables.
Intelligent modules
Intelligent modules are modules with an internal memory, able to transmit certain commands (e. g. substitute
values and others).
Load value
Predefined value for the counter module with which the count process begins.
Lightning protection
All measures taken to protect a system from damage due to overvoltages caused by lightning strike.
