SAFETY PRECAUTIONS
(Read these precautions before using this product.)
Before using this product, please read this manual and the relevant manuals carefully and pay full attention to safety to handle
the product correctly. The precautions given in this manual are concerned with this product only. For the safety precautions of
the programmable controller system, refer to the user's manual for the CPU module used.
In this manual, the safety precautions are classified into two levels: "
WARNING" and "
CAUTION".
WARNING
Indicates that incorrect handling may cause hazardous conditions, resulting in
death or severe injury.
CAUTION
Indicates that incorrect handling may cause hazardous conditions, resulting in
minor or moderate injury or property damage.
Under some circumstances, failure to observe the precautions given under "
CAUTION" may lead to serious
consequences.
Observe the precautions of both levels because they are important for personal and system safety.
Make sure that the end users read this manual and then keep the manual in a safe place for future reference.
[Installation Precautions]
WARNING
● Before touching the Vision Sensor, be sure to touch an electric conductor such as grounded metal to
discharge the static electricity from your body. Otherwise, damage or faulty operation of the Vision
Sensor may occur.
● Be sure to install the I/O connector module to the main module. If not installed, dust/water-proof
performance may not obtained.
[Installation Precautions]
CAUTION
● IP protection rating is guaranteed only when all the connectors are connected with cables or sealed
with sealing caps.
● The cable is designed to connect with its key aligned with the keyway of the connector on the Vision
Sensor. It may be damaged if you try to connect it forcibly.
[Wiring Precautions]
CAUTION
● Use only 24 V DC and observe the indicated polarity. Otherwise, fire or damage may result.
● The frame ground terminal of the I/O module and the shield ground of each connector (RS232 OUT
port and SENSOR port) are internally conducting. The system ground is designed on the condition
that a ground connection is provided. The ground potential may affect the vision system and
peripheral devices such as sequencer via cables. For safe operation, it is recommended to connect all
the ground connections securely.

[Startup and Maintenance Precautions]
CAUTION
● Do not clean the Vision Sensor VS20 with highly irritating or corrosive solvent such as caustic alkali
solution, methyl ethyl ketone (MEK), and gasoline. Doing so may cause a fault.

Connecting and wiring of the vision sensor
1.
2.
3.
Verify that the 24 V DC power supply being used is unplugged and not receiving power.
Optionally, connect the I/O or serial wires to an appropriate device (for example, a programmable controller).
Attach the power and I/O breakout cable’s [24 V DC] (Red wire) and [GND] (Black wire) to the corresponding terminals
on the power supply.
4.
Connect the power and I/O breakout cable’s M12 connector to the vision sensor’s power, I/O and RS-232 connector.
5.
Turn on the 24 V DC power supply switch.
Precautions
• When connecting the vision sensor and programmable controller, simultaneously turn on the vision sensor and
programmable controller, or first turn on the programmable controller.
• Cut unused wires or protect them with insulating materials. Keep all bare wires separated from the 24 V DC wire.
• All cable connectors are “keyed” to fit the connectors on the vision sensor. Do not force the connections or damage may
occur.

The vision sensor sends the inspection results,

the “Results Valid” status.
Basic operations of the SLMP scanner connection
In the SLMP Scanner Connection, the vision sensor reads control bit blocks from the programmable controller at the poll
interval set with In-Sight Explorer, and the processing is performed responding to the change of the bit information in the
control bit blocks.
The processing status is written to the corresponding bit in the status bit block.
To control the vision sensor, assign the devices of the programmable controller to each of the defined data blocks (including
control bit blocks) and use them.
The following shows the functions of six data blocks.
Data Blocks
Contents
Control bit block
This block is used to perform control instructions (such as trigger) to the vision sensor, using bit information. The
vision sensor is controlled by turning on and off the devices set to the control bit block using the programmable
controller.
Status bit block
This block indicates the status of the vision sensor, and can be checked with bit information.
Input word block
This block is used to input application data (including parameters for inspection) from the programmable controller,
and uses word information.
Output word block
The vision sensor uses this block to output application data (including inspection results) to the programmable
controller. This block uses word information.
String command word block
This block is used to set commands (string commands) to control the vision sensor. This block uses word information.
String command result word block
This block is used to output the results controlled by the commands. This block uses word information.
The next section shows the data blocks and the timing chart of the SLMP Scanner Connection.
