Digital Represents a value that can acquire only definite states
within a finite set, e.g. a voltage. Mostly defined as "0" and
"1".
DIN Abbreviation for "Deutsches Institut für Normungen e. V."
Dual Code Natural binary code. Frequently used code for absolute
measurement systems.
EDS This EDS file primarily defines the Polled I/O Connection, the
COS I/O Connection and the Cyclic I/O Connection of the
gateway. It does not contain data or parameters (easy
object) for functions of the easy basic unit. These functions
are accessed by means of explicit messages.
EEPROM Abbreviation for “Electrically Erasable Programmable Read-
only Memory“.
EMC Abbreviation for "Electromagnetic Compatibility". Defines
the ability of electrical equipment to operate error-free and
without causing a negative influence within a certain envi-
ronment.
EN Abbreviation for “European Norm”.
Earth In electrical engineering, the term given to conductive
ground with the electrical potential of zero at any point. In
the environment of grounding devices, the electrical poten-
tial may not equal zero, in which case it is called the "refer-
ence earth".
Earthing Represents the connection of an electrically conductive
component to the equipotential earth via a grounding
device.
Earth electrode One or several components with direct and good contact to
earth.
ESD Abbreviation for “Electrostatic Discharge”.
Fieldbus Data network on the sensor/actuator level. The fieldbus
interconnects the devices at field level. Characteristic
feature of the fieldbus is the highly reliable transfer of
signals and real-time response.
Field power supply Power supply for the field devices and signal voltage.
