XI/ON: Gateways for Modbus TCP 10 Glossary
H
I
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).
IP
Abbreviation for Internet-Protocol, protocol for the packet-oriented
and connectionless transport of data packets from a transmitter to
a receiver crossing different networks.
