■ Definition and terminology
Terminology Definition
Address
(Station Address) A number assigned to identify the unit connected onto the DeviceNet
TM
. network. It
must not be duplicated.
A
AD value
The signal from the analog input device is converted to digital, and displayed in decimal
and hexadecimal. These hexadecimal and decimal values are also outputted to the
analog output device.
Communication speed
The speed at which the fieldbus sends and receives data. It depends on higher-level
equipment (PLC, etc.) and is measured in bps (Bits per second).
C
Current consumption The current necessary to operate each unit.
DIN rail A metal rail conforming with DIN (German) standard. 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. F
Fieldbus
The protocol that uses digital communication to exchange signals between field
equipment (instruments and actuators) running on site and a PLC.
H
Handheld Terminal
(H.T.) Connected to the dedicated connector of the SI unit to adjust the internal parameters,
monitor the status of all input and output signals, and turn on input and output forcedly.
I
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.
Manifold
A form consisting of multiple components. A form made by combining multiple
components
M
MAC ID
Abbreviation for Media-Access-Control Identifier. Node addresses identifier for the
DeviceNet
TM
.
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.
