2.4.4. UDP2TCP converter

2.4.4. UDP2TCP converter​

 

As mentioned above, the Hi5a controller of the Hyundai robot supports the UDP, and the Pick-it equipment supports the TCP. To solve this problem, it is required to use the UDP2TCP converter. The function of the UDP2TCP converter is to combine “Receiving via UDP / Sending via TCP” and “Receiving via TCP/ Sending via UDP” by simultaneously realizing both the UDP and TCP communication functions.

The UDP2TCP converter has one Ethernet port that needs to be connected to the Ethernet switch using the Ethernet cable. Then, everything is set. There is no need to operate the UDP2TCP converter separately because it will start to operate automatically when it is powered and booted up simultaneously. Currently, the IP address and TCP port used by the UDP2TCP converter are fixed to the values ​​shown in Table 2-2. Users do not need to change the IP address or port number of the UDP2TCP converter. Instead, users just need to perform the setting in a way to ensure that the robot JOB file sends and receives variable via the fixed IP address and port number. The TCP port number of the UDP2TCP converter is fixed to “5001” to be compatible with the Pick-it equipment, and the UDP port number is also fixed to “5001.”

192.168.1.11

TCP port number (Fixed)

5001

UDP port number (Fixed)

5001

 

 

In other words, when sending variable from the robot via UDP, the address of the destination should be set to “192.168.1.11,” and the port number should be set to “5001.” On the Pick-it chrome setup screen, if the IP address for the robot to access is set to “192.168.1.12” and the port number is set to “5001,” then the UDP2TCP converter will convert and transfer the variable between the robot and Pick-equipment.
