9-3 PLC Link Connections
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.
●
Command/Response Communications
For PLC Link communications, command/response control signals are handled by storing control commands
from the PLC to the Vision Sensor and responses from the Vision Sensor to the PLC in the I/O memory of the
PLC. This allows you to control the operation of the Vision Sensor (e.g., perform single inspections or change
the scene) without using communications instructions.
After you write a control command to the specified Command Area in the I/O memory of the PLC, you can turn
ON the Command Execution (EXE) Bit to send the control command to the Vision Sensor via Ethernet. The
Vision Sensor executes the control command and sends a response back to the PLC via Ethernet. The PLC
stores the response in the specified Response Area in I/O memory.
●
Data Output after Measurements
Immediately after a single measurement or continuous measurements, the Vision Sensor will automatically
output to the specified I/O memory in the PLC the data for measurements that are specified for output in
advance. This enables you to easily transfer the measurement results data for inspection items to the PLC.
When handshaking is enabled, the data can be output from the Vision Sensor only when the condition to
receive that data are met at the PLC.
