1-2 Safety information
WARNING
●Never use this product as a sensing device for personnel protection.
●When using sensing devices for personnel protection, use products that meet the laws and stan-
dards for personnel protection that apply in each region or country, such as OSHA, ANSI and IEC.
Specications
●This product has been developed / produced for industrial use only.
●Do not use this product under conditions outside the specied ranges. Risk of an accident
and product damage.There is also a risk of a signicant reduction of service life.
Power supply
●Incorrect wiring will damage the internal circuitry. Check the wiring before turning ON the
power.
● Verify that power supply uctuations are within the rating.
●Risk of damage and burning if a voltage over the rating is applied, or AC power is directly ap-
plied.
●If power is supplied from a commercial switching regulator, ensure that the frame ground
(F.G.) terminal is connected to an actual ground.
● Ensure that there is su󰀩cient leeway in the voltage source capacity.
●Do not use during the initial transient time after the power supply is switched ON
For details, refer to “4-5 Initial operation after power is turned ON”.
●Use an isolation transformer in the DC power supply. Risk of short-circuiting and damage to
the product or power supply if an auto transformer is used.
●If surges occur in the power supply, connect a surge absorber to the source to absorb the
surges.
Wiring
●Make sure that the power is OFF while performing wiring or connection work. Risk of electric
shock or product damage.
●Risk of damage and burning if the load is incorrectly wired or short-circuiting occurs.
●When noise generating equipment (switching regulator, inverter motor, etc.) is used in the vi-
cinity of this product, connect the frame ground (F.G.) terminal of the equipment separately to
ground.
●To avoid noise, keep the wiring as short as possible.
●Do not wire in parallel with a high-voltage line or power line, or run through the same conduit.
Risk of malfunctioning due to induction.
● For the communication cable, use a dedicated cable that is certied by CC-Link Partner As-
sociation.
●For detailed grounding specications, refer to the installation manual published by the CC-
Link Partner Association.
Usage environment
●This product is suitable for indoor use only.
●Avoid dust, dirt, and steam.
●Do not use in locations where there are corrosive or other harmful gases.
●Ensure that the product does not come into contact with organic solvents such as thinner.
●Ensure that the product does not come into contact with strong acid or alkaline.

Term Meaning
System
terms
Transient transmission
A function in Data Link for communication with other stations using
peripheral devices, including reading or writing data from / to another
station by means of a read / write command in the program of the local
station.
Cyclic transmission
A function in Data Link for periodic data communication between stations
on the same network.
Memory map
This assigns functions of a communication unit to a link device. By ac-
cessing a link device that supports memory map, the master station can
use the functions of a communication unit.
Station number
This number is assigned to identify each network unit connected to a
network.
The same number cannot be assigned to more than one network unit in a
network.
RX[*]
Remote input
Information input from a slave station to the master station in units of
bits.
[*]: Indicates the bit number in hex.
RY[*]
Remote output
Information output from the master station to a slave station in units of
bits.
[*]: Indicates the bit number in hex.
RWw[*]
Remote register (output)
Information output from the master station to a slave station in units of
words (16 bits).
[*]: Indicates the word number in hex.
RWr[*]
Remote register (input)
Information input from a slave station to the master station in units of words
(16 bits).
[*]: Indicates the word number in hex.
Unit name
Master station
This station controls the overall network. The master station can com-
municate with all stations by cyclic transmission and transient transmis-
sion.
Slave station A general name for stations other than the master station (local station,
remote I/O station, remote device station, intelligent device station).
Remote I/O station
Exchanges input / output signals in units of bits with the master station by
cyclic transmission.
Remote device station
Sends information in units of bits and information in units of words by
cyclic transmission. Returns a response to a transient transmission from
another station.
Intelligent device sta-
tion
Sends input / output signals in units of bits and input / output data in
units of words to the master station by cyclic transmission. Returns a re-
sponse to a transient transmission (request) from another station.
Local station
Communicates with the master station and other local stations by cyclic
transmission and transient transmission.
Controller - Master unit A controller equipped with power supply, external I/O, and analog cur-
rent output wires, and which can be used on a standalone basis.
Controller - Slave unit A controller that is connected to a master unit.
CC-Link dedicated
cable
Cable certified by CC-Link Partner Association (shielded 3-conductor
twisted-pair cable).
End plates or commer-
cially available ttings
When the product is connected to a controller, the end plates secure
the units at both ends to prevent the connector from disconnecting and
causing a communication failure.

●If HG-SC series and HG-TC series controllers are used in combination, connect the slave con-
trollers of the same series as the master controller on the near side of the master controller and
connect the slave controllers of di󰀨erent series from the master controller on the far side of the
master controller.

●If HG-SC series and HG-TC series controllers are used in combination, there are limitations on
the functions below.
Item Description of limitation
1Calculation function
Calculation is only performed when the slave unit is the same series as
the master unit.
Calculation is not performed when the slave unit series is di󰀨erent from
the master unit series. "CALC" does not appear in the displays of a slave
unit of a di󰀨erent series.
2Input all
The master unit only performs input all when the slave unit is the same
series.
A Slave unit of a di󰀨erent series than the master unit are not input even
when the external input settings match those of the master unit.
3Copy function
Copying is only performed when the slave unit is the same series as the
master unit.
"NOW COPY" appears on the displays of the master unit and slave unit
when the slave unit is di󰀨erent series from the master unit, but copying is
not performed.
4Interference prevention This function is only available on the HG-TC series controller. The func-
tion is not executed on the HG-SC series controller.

●When connecting slave units to a master unit, connect only NPN output types, or only
PNP output types. Dissimilar output types cannot be connected together.
●If an HG-SC series controller manufactured in January 2019 or earlier is connected to an
HG-TC series controller, operation will not take place normally. If they are used together,
use an HG-SC series controller manufactured in February 2019 or later.
