Basic operation flow of the SLMP scanner connection

Vision sensor
Set poll interval
While the trigger is on,
communication between
data import and the completion
of inspection is performed
regardless of the poll interval.

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.

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.
This block indicates the status of the vision sensor, and can be checked with bit information.
This block is used to input application data (including parameters for inspection) from the programmable controller,
and uses word information.
The vision sensor uses this block to output application data (including inspection results) to the programmable
controller. This block uses word information.
This block is used to set commands (string commands) to control the vision sensor. This block uses word information.
This block is used to output the results controlled by the commands. This block uses word information.
