Some of the common issues and their solutions that you encounter with PC SDK are tabulated here:

Issue	Solution
Unable to connect to controllers?	Ensure that the RobotWare option is available in the system on the controller. This applies to both virtual and real controllers.
Is the GUI hanging?	Ensure to use Invoke when modifying the user interface due to a robot controller event. For more information, see Controller events and threads.
Do you encounter a problem that is related to netscan?	You must increase the time allowed for scanning if `NetworkScanner.Scan` does not find the robot controller during netscan. Increase the time in an app.config file as explained in Application configuration file or add the time directly in the code as follows. `NetworkScanner aScanner = new NetworkScanner(); aScanner.Scan(); System.Threading.Thread.Sleep(4000); aScanner.Scan();`
Do you get Invalid Client ID when trying to do a read operation towards the robot controller?	This issue can be resolved by ensuring that you are logged in to the controller. To write to RAPID data or to write to the configuration database, mastership is required. To get write access, the client must request mastership of the controller resource it wants to manipulate. For more information, see Logon and Logoff and Mastership.
