This post summarizes all the issues encountered in communication with UR robots through master control and standard interface, along with their solutions.
Network
IPC and robot are not in the same subnet
- Reason: The IP addresses of the IPC and the robot need to be set in the same subnet, otherwise they cannot connect.
- Solution: Check the IP addresses of the IPC and the robot to ensure they are in the same subnet.
IPC firewall is not disabled
- Solution: Go to Control Panel/System and Security/Windows Defender Firewall, and disable all firewalls.
Duplicate subnets for IPC IP
- Solution: Open a CMD window and type ‘ipconfig’ to check the subnets for all network interfaces. Change the duplicated subnet.
Operations

- Reason: The robot can only be controlled to move by the master controller when in remote mode.
- Solution: Click on the teach pendant settings/system/remote control, enable remote control, then return to the main interface and switch to remote control mode in the upper right corner.
