Precautions Only one Vision Sensor can be connected to the robot controller. If you want to connect to another Vision Sensor, disconnect from the connected Vision Sensor. Example In the following example, we will connect to the Vision Sensor with IP address "10.5.5.100" and port number "9876". $ip_address = "10.5.5.100" $port_no = "9876" retries_connect = 2 timeout_connect = 4 socket_no = 0 CALL fhconnect($ip_address, $port_no, retries_connect, timeout_connect, socket_no, err_no) 41
