.. _script_sender: ScriptSender ============ The ``ScriptSender`` class opens a tcp socket listens for "*request_program*" request. Upon such a request, a predefined URScript code is sent to the caller. The script code itself has to be passed to the ``ScriptSender``'s constructor. Use this class in conjunction with the `External Control URCap `_ which will make the corresponding request when starting a program on the robot that contains the **External Control** program node. In order to work properly, make sure that the IP address and script sender port are configured correctly on the robot. An example of how to use the ``ScriptSender`` class can be found in the :ref:`script_sender_example`. .. note:: PolyScope X users cannot use the URCap linked above. There is a development version of a URCapX available at https://github.com/UniversalRobots/Universal_Robots_ExternalControl_URCapX.
