INTRODUCTION
Connecting and Wiring the System
(1) External power supply connection (In-Sight EZ-700 series, In-Sight 7000 series, In-Sight
5000 series)
1) Make sure that the switch of 24 V DC power supply is off.
2) Connect the power cable of a breakout cable and the terminal compatible with the power supply.
(Check the compatible cable in the following diagram.)
(2) Connection of the vision system and a breakout cable (In-Sight EZ-700 series, In-Sight 7000
series, In-Sight 5000 series)
Connect a power supply and I/O breakout cable to the PWR connector of the vision system.
CAUTION
Cut unused wires or protect them with insulating materials. Prevent them from being
short-circuited with the +24 V DC wire.
WARNING
Do not use the voltage other than 24 V DC. Comply with the polarity as
described.

BASIC OPERATIONS OF THE SLMP SCANNER
Basic Operations of the SLMP Scanner
In the SLMP Scanner, the vision system reads control 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 blocks.
The processing status is written to the corresponding bit in the status block.
To control the vision system, assign the devices of the programmable controller to each of the defined
data blocks (including control blocks) and use them.
The following shows the functions of six data blocks.
• Control block: This block is used to send control commands (including triggers) to the
vision system. This block uses bit information. The vision system is
controlled by turning on and off the devices set to the control block
using the programmable controller.
• Status block: This block indicates the status of the vision system, and can be
checked with bit information.
• Input block: This block is used to input application data (including parameters for
inspection) from the programmable controller, and uses word
information.
• Output block: The vision system uses this block to output application data (including
inspection results) to the programmable controller. This block uses
word information.
• String command block: This block is used to set commands (string commands) to control the
vision system. This block uses word information.
• String command result 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.
Data Blocks
The following shows the six data blocks defined to control the vision system.

BASIC OPERATIONS OF THE SLMP SCANNER
Timing Chart of the SLMP Scanner
The following shows a timing chart when "Trigger" of the control block is turned on from the
programmable controller.
To enable the trigger from the programmable controller, turn on "Trigger Enable" of the control block.
When "Trigger" of the control block is turned on from the programmable controller while "Trigger Ready"
of the status block is on, the status of the vision system is output to "Trigger Ack", "Acquiring",
"Inspecting", and "Inspection Completed" of the status block.
"Inspection Completed" changes (toggles) the status at every completion.
