/Usage of network interfaces

The Universal Robots system has a wide number of network interfaces, that provide various functionality. 
In order to assure robustness, it is important that URCaps and other processes, does not interfere with these interfaces. 

When designing a URCap that use TCP socket communication or similar network protocols, it is heavily recommended to use a high port number, to reduce the risk of conflicts. Generally, ports above 32768 are recommended, unless another port is explicitly required. 

/Reserved ports

The following ports or port ranges are considered to be reserved by UR, in the localhost of the robot. 
URCaps are to not use any of these ports in the localhost system. 

• 21 - 23
• 53
• 67 - 68
• 80
• 443
• 502
• 2222
• 6666
• 7827
• 7828
• 8080
• 29919
• 29998
• 29999 - 30100
• 34964
• 40000
• 40002
• 44818
• 49152
• 50000 - 50100

In addition you should pay attention to the ports used by other URCaps. An overview can be found on the UR+ Forums in post.

Please remember to add your usage!
