Terminology
Definition
100 100BASE-TX
Standard of LAN transmission line with communication speed of 100
Mbps.
C
Current consumption
The current necessary to operate each unit.
DHCP
The protocol which automatically set the information such as IP address which needs to
be registered in order to use the network. Those information are set to each equipment
which are connected to TCP/IP network.
DIN rail
A metal rail conforming with DIN (German) standard.
DLR
An abbreviation for Device Level Ring: Performs a fast switching of the communication
route when any problem occurs with the Ring network, to maintain communication.
D
D Side
The side connected to the end plate when the product is connected to a manifold.
EDS
Settable attribute information of a device (each parameter’s object address, etc.)
stored on external disk.
E
Enclosure (IP
□□
)
Abbreviation of international (ingress) protection. A standard related to the protection from
external objects (hands, steel ball, steel wire, dust, water, etc.) applied to the product.
FE
Abbreviation of functional earth.
Fieldbus
The protocol that uses digital communication to exchange signals between field
equipment (instruments and actuators) running on site and a PLC.
F
Full duplex
Communication system that can send and receive data at the same time bi-directionally.
H
Half duplex
Communication system that sends and receives data in one direction at a time.
Idle
Expression for PLC operation state. For details, Refer to manuals of each PLC maker.
Depending on which PLC is used; the idle state might not be available.
I
IP address
A 32 bit digit sequence which is assigned to identify devices which are connected to the
network.
MAC address
A unique number inherent to all devices which are connected to EtherNet/IP
TM
.
M
Manifold
A form consisting of multiple components. A form made by combining multiple components.
NPN input
Takes the sensor output that uses the NPN transistor to the signal output line.
NPN output
The output type that uses an NPN transistor to operate output device. It is also known
as a positive common type since a positive potential is applied to the power supply line.
Number of inputs
The number of points that can receive information from input device (sensor, switch, etc.).
N
Number of outputs
The number of points that can operate output device (solenoid valve, light, motor, etc.).
O
Open circuit detection
A diagnosis function to detect if the input or output device wiring is disconnected.
PLC
Abbreviation of programmable logic controller. A digital computer used for automation of
electromechanical processes.
PNP input
Takes the sensor output that uses the PNP transistor to the signal output part.
P
PNP output
The output type that uses a PNP transistor to operate output device. It is also known as
a negative common type since a negative potential is applied to the power supply line.
Q
QuickConnect
TM
The function that reduces the time from the power being supplied to the equipment
operating and communication starting.
Short circuit detection
A diagnosis function to detect an over current due to the short circuit of the output and/or
power supply positive line with respect to the GND line.
Short circuit
protection
A function to protect the internal circuit from being broken by an over current due to the
short circuit of the output and/or power supply positive line with respect to the GND line.
S
SI unit
Abbreviation of serial interface unit. A unit connected to a PLC to communicate input
and output data.
U
U Side
The side connected to the solenoid valve when the product is connected to a manifold.
