3-2 Controlling Operation and Outputting Data with PLC Link Communications
This section explains how to configure the communication settings that are required for communication
between the sensor and external devices by PLC Link. Communication specifications (PLC I/O memory area
used for PLC Link communication and types of communication commands) are also described, and a
communication timing chart is provided.
Communications Processing Flow
You can use a PLC Link to communicate between the PLC and the Vision Sensor to perform control via
command/response communications or to output data after measurements. You can use these
communications methods simultaneously.
For PLC Link communications, the following three communications areas are set in the PLC to perform
communications.
You can set the area and address settings in the communications specifications of the Vision Sensor to assign
the above three communications areas in the I/O memory of the PLC.
Command/response
communications
1. Command area
This is the area to which you write control commands for the
Vision Sensor to execute.
2. Response area
This is the area to which the Vision Sensor writes the results of
control commands executed from the Command Area.
Data output after mea-
surements
3. Output area
This is the area to which the Vision Sensor writes output data for
measurements after an inspection is performed.
Command area
The following control commands are
written to the Vision Sensor.
●
