hello,  
iam using “JointTarget aJointTarget = controller2.MotionSystem.ActiveMechanicalUnit.GetPosition()”  
to getting the position of my roboter in RobotStudio(i also know the method task.GetJointTarget().RobAx…)

Is there a way to get an event, that tells me when the values of the axis has been changed.

thanks
