CAUTION
Indicates a potentially hazardous situation which, if not avoided, may result in minor or
moderate injury and could cause property damage.
•Never use the input function of MONITOUCH for operations that may threaten human life or to damage the
system, such as switches to be used in case of emergency. Please design the system so that it can cope
with malfunction of a touch switch. A malfunction of the touch switch will result in machine accident or
damage.
•Turn off the power supply when you set up the unit, connect cables or perform maintenance and inspection.
Otherwise, electrical shock or damage may occur.
•Never touch any terminals while the power is on. Otherwise, electric shock may occur.
•You must put a cover on the terminals on the unit when you turn the power on and operate the unit. Without
the terminal cover in place, an electric shock may occur.
•The liquid crystal in the LCD panel is a hazardous substance. If the LCD panel is damaged, never swallow
the leaked liquid crystal. If the liquid crystal spills on your skin or clothing, use soap and wash off thoroughly.
•For MONITOUCH using a lithium battery, never disassemble, recharge, deform by pressure, short-circuit,
nor reverse the polarity of the battery, and never dispose of the battery in fire. Failure to follow these
conditions will lead to explosion or ignition.
•For MONITOUCH using a lithium battery, never use a battery that is deformed, leaks, or shows any other
signs of abnormality. Failure to follow these conditions will lead to explosion or ignition.
CAUTION
DANGER
•Check the appearance of the unit when it is unpacked. Do not use the unit if any damage or deformation is
found. Failure to do so may lead to fire, damage or malfunction.
•For use in a facility or for a system related to nuclear energy, aerospace, medical, traffic equipment, or
mobile installations, please consult your local distributor.
•Operate (or store) MONITOUCH under the conditions indicated in this manual and related manuals. Failure
to do so could cause fire, malfunction, physical damage or deterioration.
•Understand the following environmental limits for use and storage of MONITOUCH. Otherwise, fire or
damage to the unit may result.
- Avoid locations where there is a possibility that water, corrosive gas, flammable gas, solvents, grinding
fluids or cutting oil can come into contact with the unit.
- Avoid high temperature, high humidity, and outside weather conditions, such as wind, rain or direct
sunlight.
- Avoid locations where excessive dust, salt, and metallic particles are present.
- Avoid installing the unit in a location where vibration or physical shock may be transmitted.
•Equipment must be correctly mounted so that the main terminal of MONITOUCH will not be touched
inadvertently. Otherwise, an accident or electric shock may occur.
•Tighten the fixtures of the MONITOUCH with a torque in the specified range. Excessive tightening may
distort the panel surface. Loose tightening may cause MONITOUCH to come off, malfunction or be
short-circuited.
•Check periodically that terminal screws on the power supply terminal block and fixtures are firmly tightened.
Loosened screws may result in fire or malfunction.
•Tighten terminal screws on the power supply terminal block equally to a torque of 0.5 N•m. Improper
tightening of screws may result in fire, malfunction, or trouble.
•MONITOUCH has a glass screen. Do not drop or give physical shock to the unit. Otherwise, the screen
may be damaged.
•Connect the cables correctly to the terminals of MONITOUCH in accordance with the specified voltage and
wattage. Over-voltage, over-wattage or incorrect cable connection could cause fire, malfunction or damage
to the unit.
•Be sure to establish a ground of MONITOUCH. Ground FG terminal which must be used for the unit.
Otherwise, electric shock or a fire may occur.
•Prevent any conductive particles from entering into MONITOUCH. Failure to do so may lead to fire, damage
or malfunction.
•After wiring is finished, remove the paper used as a dust cover before starting to operate MONITOUCH.
Operation with the cover attached may result in accident, fire, malfunction, or trouble.
•Do not attempt to repair MONITOUCH at your site. Ask Hakko or the designated contractor for repair.
•Do not disassemble or modify MONITOUCH. Otherwise, it may cause a malfunction.
•Hakko Electronics Co., Ltd. is not responsible for any damages resulting from repair, overhaul or
modification of MONITOUCH that was performed by an unauthorized person.
•Do not use a sharp-pointed tool when pressing a touch switch. Doing so may damage the screen.
•Only experts are authorized to set up the unit, connect the cables or perform maintenance and inspection.
•For MONITOUCH using a lithium battery, handle the battery with care. The combustible materials such as
lithium or organic solvent contained in the battery may generate heat, explode, or catch fire, resulting in
personal injury or fire. Read related manuals carefully and handle the lithium battery correctly as instructed.
•When using a MONITOUCH that has analog switch resolution with resistance film, do not press two or more
points on the screen at the same time. If there is a switch between the two pressed points, it may be
activated.
•Take safety precautions during such operations as setting change during running, forced output, start, and
stop. Any misoperation may cause unexpected machine motions, resulting in machine accident or damage.
•In facilities where a failure of MONITOUCH could lead to accident threatening human life or other serious
damage, be sure that the facilities are equipped with adequate safeguards.
•At the time of disposal, MONITOUCH must be treated as industrial waste.
•Before touching MONITOUCH, discharge static electricity from your body by touching grounded metal.
Excessive static electricity may cause malfunction or trouble.
CAUTION
[General Notes]
•Never bundle control cables and input/output cables with high-voltage and large-current carrying cables such
as power supply cables. Keep these cables at least 200 mm away from the high-voltage and large-current
carrying cables. Otherwise, malfunction may occur due to noise.
•Plug connectors or sockets of MONITOUCH in the correct orientation. Otherwise, it may cause a malfunction.
•Do not use thinners for cleaning because they may discolor the MONITOUCH surface. Use alcohol or benzine
commercially available.
•If a data receive error occurs when MONITOUCH and the counterpart (PLC, temperature controller, etc.) are
started at the same time, read the manual for the counterpart unit and handle the error correctly.
•Avoid discharging static electricity on the mounting panel of the MONITOUCH. Static charges can damage the
unit and cause malfunctions. Otherwise, malfunction may occur due to noise.
•Avoid prolonged display of any fixed pattern. Due to the characteristics of the liquid crystal display, an
afterimage may occur. If a prolonged display of a fixed pattern is expected, use the auto OFF function of the
backlight.

1. Before Connecting to PLC
Types of Connection
There are four types of connection between MONITOUCH(es) and PLC(s).
1 : 1 Connection
Outline
One set of the V7 series is connected to one PLC (1 : 1 connection).
The wiring diagrams and the description of settings for connection to PLCs in 1 : 1 connections can be
found from Chapter 2 onward.
The host link unit of the PLC or the CPU port is used and the V7 series (master station) establishes
communications according to the protocol of the PLC. Consequently, it is not necessary to have the
dedicated communication program on the PLC (slave station). The V7 series reads the PLC memory
for screen display. It is also possible to write switch data or numerical data entered through the keypad
directly to the PLC memory.
Connection
The interface used for 1 : 1 connection varies depending on the V7 series model.
•CN1 (D-sub 25-pin) for V7 series and V706 + DU-01
•MJ2 (RJ-45 8-pin) for V706
For details on wiring and settings for 1 : 1 connection, refer to page 1-8.

n : 1 Connection (Multi-link 2)
Outline
•One PLC is connected to a maximum of four V7 series.
•An original network is created where the V7 series (Local Port 1) that is directly connected to the
PLC is the master station, and other three V7 series are slave stations. Only the master station
makes communications directly with the PLC, and the slave stations make communications with
the PLC via the master station.
•Communications between the V7 master station and the PLC depend on the communication
speed set on the PLC. The maximum available speed for the V7 series is 115 kbps, which is
higher than the one available with multi-link connection described in “n : 1 Connection (Multi-link)”
(page 1-4).
•This multi-link connection is available with almost all the PLC models that support 1 : 1 connection
(refer to the “Appendix”).
The connection between the master station and the PLC is the same as the one for 1 : 1
connection.
•Use the RS-485 2-wire connection between stations of the V7 series. Please use Hakko
Electronics’ multi-link 2 master cable (V6-MLT) for connection between the master station (Local
Port 1) and the slave station (Local Port 2).
•In the following cases, multi-link 2 connection is not available.
1. A communication interface unit (example: OPCN-1, CC-LINK, Ethernet, etc.) is used.
2. The V6 series (master or slave station) is used for the temperature control network or
PLC2Way function.
•The V7 and V6 series can be used together. The V6 series can be the master station.
(However, when V606/V606i is the master station, the slave station must be V606/V606i. Also,
depending on the hardware version of the V6 series, multi-link 2 connection may not be supported.
Refer to the V6 Hardware Specifications.)

Connection between MJ2 and PLC
There are two connection methods.
•With MJ2-PLC
One method uses an adaptor MJ2-PLC for connection between MJ2 and the D-sub 25-pin
connector plus a PLC communication cable.
For connection of a PLC communication cable, refer to the CN1 pin arrangement.
•With V6-TMP
Refer to the PLC wiring diagram and the MJ2 pin arrangement.

Wiring (1 : 1 Connection)
Prepare the communication cable with the PLC on your side.
Refer to the following information for the cable.
For more information on the connection to respective PLCs, refer to “Chapter 2” and later.
RS-232C Connection
•Connect the shielded cable either to the V7 series or PLC side. This connection diagram shows
the case where the shielded cable is connected on the V7 series side.
When connecting the shielded cable to the V7 series side, connect it to pin 1 of the connector or
the connector case cover.
The metal shell of the modular jack 2 on the V706 is used as SG (signal ground). Connect the
shielded cable to the metal shell of modular jack 2.
•Twisted pairs of 0.3 mm sq. or above are recommended.
•If noise disturbs communications, use twisted pairs between SD/SG and RD/SG.
DANGER Electric shock hazard
Shut the power off before connecting cables.

RS-422/485 Connection
•Connect twisted pairs between +SD/−SD and +RD/−RD.
•If the PLC has the terminal for signal ground (SG), be sure to connect a wire.
•Connect the shielded cable either to the V7 series or PLC side. This connection diagram shows
the case where the shielded cable is connected on the V7 series side.
When connecting the shielded cable to the V7 series side, connect it to pin 1 of the connector or
the connector case cover.
The metal shell of the modular jack 2 on the V706 is used as SG (signal ground). Connect the
shielded cable to the metal shell of modular jack 2.
•To use a terminal block for connection, use Hakko Electronics’ “TC485” optionally available. When
using TC485 on the V706, the option unit DU-01 must be installed.
•The DIP switch on the side or back of V7 series units is used to set the terminating resistors. For
more information, refer to the description of the DIP switch setting in the relevant Hardware
Specifications.
•Twisted pairs of 0.3 mm sq. or above are recommended.
