A Unit that provides two interfaces to connect peripheral devices to a Net
Link System.
One of the positions in a LAN. Each node incorporates a device that can
communicate with the devices at all of the other nodes. The device at a node
is identified by the node number. One loop of a Net Link System (OMRON’s
LAN) can consist of up to 126 nodes. Each node is occupied by a Net Link
Unit mounted to a PC or a device providing an interface to a computer or
other peripheral device.
An input that is normally open, i.e., the input signal is considered to be pres-
ent when the circuit connected to the input closes.
Disturbances in signals caused by electrical noise.
A hardware or software error that produces a warning but does not stop the
PC from operating.
A condition that produces an ON execution condition when the bit assigned
to it is OFF, and an OFF execution condition when the bit assigned to it is
ON.
A condition that produces an ON execution condition when the bit assigned
to it is ON, and an OFF execution condition when the bit assigned to it is
OFF.
A logic operation which inverts the status of the operand. For example, AND
NOT indicates an AND operation with the opposite of the actual status of the
operand bit.
An acronym for Network Service Board.
An acronym for Network Service Unit.
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.
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).
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.
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).
A bit that is turned ON or OFF for a specified interval of time which is longer
than one cycle.
Removing a Rack-mounted Unit for replacement or maintenance during PC
operation.
