Term
Definition
C Communication
speed
Data receive and transmit speed used by the fieldbus. This depends on master equipment (PLC etc.),
the unit used is bps (bit per second).
C Current consumption
The amount of current required by each unit in order to operate.
D D side
The DOWN side of the manifold, where EX600 end plate is connected
D DeviceNet
Open fieldbus for factory automation. Developed by Rockwell Automation. Currently headquartered in
America and expanding into Europe, Japan and China
D DIN rail
Metal rail in accordance with the DIN standard.
E EDS
Settable attribute information for a device (each parameter’ s object address, etc.) stored on external
disk.
F FE
Functional
Earth.
F Fieldbus
Type of communication system between a PLC and factory equipment (such as measuring
instruments or machines), in which data is exchanged by digital communication.
H
Hand-held terminal
(HT)
A unit to connect with the SI unit PCI connection, for parameter adjustment, to monitor all input and
output signal status, and for Forced input/output selection.
I
ID No.
16 bit number which is assigned by PNO to identify the product
I Idle
Expression for PLC operational state. For details, refer to manual of appropriate PLC. Depending on
which PLC is used; the idle state might not be available.
I
Input points
Number of points that which can receive information from input equipment. (Sensor and switch, etc.)
M MAC-ID
Abbreviation for Media-Access-Control Identifier. Node address identifier for the DeviceNet.
M Manifold
An assembly with many openings for receiving and distributing fluid or gas.
N NPN input
Input that receives data from sensor with an NPN output signal.
N NPN
output
Output that switches a load through an NPN transistor. The +ve side of the load is connected to a
ve. For this reason, NPN output is often referred to as “common positive”.
O Open circuit detection
Diagnostic function that detects open circuit, caused by broken or disconnected wiring to the
input/output equipment.
O Output
points
Number of points of output equipment (Solenoid Valve, lamp, motor starter, etc.), which can be
operated.
P PLC
Programmable Logic Controller. A Controller which performs sequential control using programs of
logical, order and arithmetic operation, etc.
P PNP input
Input that receives data from sensor with PNP output signal.
P PNP
output
Output that switches a load through a PNP transistor. The –ve side of the load is connected to the 0 V
common return. For this reason, PNP output is often referred to as “common negative”.
P
Protection class
(IP
□□
)
International Protection Rating. A Standard related to protection against foreign objects into electrical
enclosures. (Hand, wire, dust, and water, etc.)
S Short circuit detection
Function that detect if output or power supply positive line is short circuited with GND, thus over
current state has occurred.
S Short circuit protection
Internal circuit protection to prevent damage by over current caused by power supply positive line
being short circuited with GND
S SI unit
Serial Interface unit. A unit for connection with a PLC to perform input/output data communication.
T Terminating
resistance
When connecting devices to the fieldbus, resistance must be installed on both ends of the wiring
system. This prevents signal reflection and maintains data integrity.
U U side
The UP side of the manifold, where solenoid valve manifold is connected.
