This is a TCP/IP connection between Disk Color Detection Master (PC1) and Disk Color Detection Slaves (PC6), where the slave works as a TCP server and the master as a TCP client. The slave application uses a video camera to take snapshots of the roller-belts. When a part is detected a snapshot is sent to the master, which will be used to detect the color of the part. The images have a size between 2 and 3 Kbytes. When the part is not detected anymore a small 4-byte message is sent to the master. A new part is feed into to the system every 3 seconds, thus this will be also the maximum periodicity of this stream.
