Glossary 6
transformers, motors, mains cables installed parallel and RF signal
cables.
Capacitive coupling
Capacitive (electrical) coupling develops between two conductors
carrying different potentials. Typical interference sources are, for
example parallel signal cables, contactor relays and static discharge.
Coding element
Two-part element for the unambiguous allocation of electronic and
basic module.
Command modules
Command-capable modules are modules with an internal memory that
are capable of executing particular commands (such as output
substitute values).
CONFIGURE...
Systematic arrangement of the I/O modules of a station.
Protected against short-circuit
Property of electrical equipment. Short-circuit-proof equipment has
the ability to withstand the thermal and dynamic loads that may occur
at the location of installation on account of a short-circuit.
LSB
Abbreviation for “Least Significant Bit“. Bit with the least significant
value.
Chassis ground
All interconnected inactive equipment parts which are not subject to
hazardous fault voltage.
Earthing tape
Flexible conductor, mostly braided. Interconnects inactive parts of
equipment, e.g. the doors of a control panel and the switch cabinet
body.
Master
Station or node in a bus system that controls communication between
the other stations of the bus system.
