■Definition and terminology
Terminology Definition
FE Abbreviation of functional earth. The word "earth" refers to this functional earth.
NFC
Abbreviation of Near Field Communication. Non-contact short distance wireless
communication. It is accessible using a card reader/ writer by using a special application.
PID
Abbreviation of Product ID. A numeric string of 32-bits allocated to the identify of the
wireless unit (base / remote).
PLC
Abbreviation of Programmable Logic Controller. A digital computer used for automation of
electromechanical processes.
PNP output
The output type that uses a PNP transistor to operate an output device. It is also known as
a negative common type since a negative potential is applied to the power supply line.
PNP Input Takes the sensor output that uses the PNP transistor to the signal output part.
Number of
outputs
Number of points which can operate output equipment such as a valve, lamp or motor
starter.
Current
consumption
Current which is necessary to operate each unit.
Broken line
detection
A broken wire to the input or output equipment has been detected by the diagnostic
function.
Short circuit
detection
Diagnostic function which detects generation of over current due to a short circuit between
the output and the positive power supply line or the ground line.
Short circuit
protection
Function which avoids damage to the internal circuit when over current is generated due to
short circuit between the output and the positive power line or the ground line.
Number of inputs
Number of points which can receive information from input equipment such as a sensor or
switch.
Pairing
Registration of the Product ID (PID) of the connectable remote. Registration occurs at the
initial setting, then wireless system will activate.
Base
A unit which establishes wireless communication of input or output data to the remote. It is
connected to a PLC to establish communication of input or output data.
Enclosure (IP)
Abbreviation of International Protection. Standard related to protection against extraneous
matter, such as hand, steel ball, steel wire, dust particle or water, applied to the product.
Manifold Manifold.
Wireless System A general term for the network including base and remote units.
Wireless channel Identification number of the remote unit connected to the base.
Wireless unit Wireless communication unit. A general term for base and remote units.
Remote A unit which establishes wireless communication of input or output data to the base.
