Protective conductor Conductor required for human body protection against
hazardous currents. Abbreviation: PE (“Protective Earth“).
Serial Describes an information transfer technique. Data are trans-
ferred in a bit-stream across the cables.
Slave Station or node in a bus system that is subordinate to the
master.
PLC Abbreviation for Programmable Logic Controller.
Station Function unit or module, consisting of several elements.
Noise emission (EMC) Testing procedure to EN 61000-6-4
Noise immunity (EMC) Testing procedure to EN 61000-6-2
Radiation coupling Radiated coupling occurs when an electromagnetic wave
makes contact with a conductor structure. The impact of the
wave induces currents and voltages. Typical interference
sources are, for example ignition circuits (spark plugs,
commutators of electrical motors) and transmitters
(e.g. radio-operated devices), which are operated near the
corresponding conductor structure.
Topology Geometrical network structure, or circuit arrangement.
UART Abbreviation for “Universal Asynchronous Receiver/Trans-
mitter“. A "UART" represents a logical circuit used to
convert an asynchronous serial data stream into a parallel
bit stream and vice versa.
UCMM The DeviceNet gateway provides an option of configuring
dynamic connection objects via the UCMM port
(Unconnected Message Manager Port).
Unidirectional Operating in one direction.
