I have established communication with the robot using my app.  
How can I detect the status of the tool IO input in real time and make corresponding operations to make the robot enter the force control mode?

thanks!

Hello-

I would recommend taking a look at our guide on remote control via TCP/IP here: [Remote Control Via TCP/IP - 16496](https://www.universal-robots.com/articles/ur/interface-communication/remote-control-via-tcpip/)  
Specifically the ‘ClientInterfaces\_Primary.pdf’ document. In section 2.1.4 in that document, tool data is described as something that can be monitored

For more information on our client interfaces, this would be a good place to start:[Overview of client interfaces - 21744](https://www.universal-robots.com/articles/ur/interface-communication/overview-of-client-interfaces/)
