Glossary
233
node
One of the positions in a LAN. Each node incorporates a device that can commu-
nicate with the devices at all of the other nodes. The device at a node is identified
by the node number.
node number
An address used to differentiate nodes (including Ethernet Units) on OMRON
networks for FINS protocol. The node number of a CV-series PC is called the
“unit number” in the PC Setup.
noise interference
Disturbances in signals caused by electrical noise.
nonfatal error
A hardware or software error that produces a warning but does not stop the PC
from operating.
NSB
An acronym for Network Service Board.
NSU
An acronym for Network Service Unit.
octal
A number system where all numbers are expressed in base 8, i.e., numbers are
written using only numerals 0 through 7.
odd parity
A communications setting that adjusts the number of ON bits so that it is always
odd. See parity.
OFF
The status of an input or output when a signal is said not to be present. The OFF
state is generally represented by a low voltage or by non-conductivity, but can be
defined as the opposite of either.
OFF delay
The delay between the time when a signal is switched OFF (e.g., by an input
device or PC) and the time when the signal reaches a state readable as an OFF
signal (i.e., as no signal) by a receiving party (e.g., output device or PC).
offset
A positive or negative value added to a base value such as an address to specify
a desired value.
ON
The status of an input or output when a signal is said to be present. The ON state
is generally represented by a high voltage or by conductivity, but can be defined
as the opposite of either.
ON delay
The delay between the time when an ON signal is initiated (e.g., by an input
device or PC) and the time when the signal reaches a state readable as an ON
signal by a receiving party (e.g., output device or PC).
operand
The values designated as the data to be used for an instruction. An operand can
be input as a constant expressing the actual numeric value to be used or as an
address to express the location in memory of the data to be used.
operating error
An error that occurs during actual PC operation as opposed to an initialization
error, which occurs before actual operations can begin.
optical communications
A communications method in which signals are sent over optical fiber cable to
prevent noise interference and increase transmission distance.
output
The signal sent from the PC to an external device. The term output is often used
abstractly or collectively to refer to outgoing signals.
output signal
A signal being sent to an external device. Generally an output signal is said to
exist when, for example, a connection point goes from low to high voltage or from
a nonconductive to a conductive state.
