The method and system further include placing the image data of the subpicture element in the identified subpicture area.
Abstract: A control system for controlling an industrial robot and a method thereof. A control unit generates a control signal for controlling the motor. At least one drive unit controls the motor. The drive unit includes a switching unit adapted to convert DC current to alternating current to the motor in dependence on the control signal. A safety unit generates a stop signal for stopping the robot upon occurrence of a safety event. The drive unit disables the switching unit upon receiving the stop signal. The safety unit generates the stop signal with a time delay with respect to the safety event. The control unit generates the control signal in such a way that the motor is electrically braked during the time delay.

Abstract: A device and a method for synchronization of a robot program and a graphical program. The device includes a first converter adapted to convert a graphical program into a first sequence of tokens representing data for motions and actions contained in the graphical program. A second converter is adapted to convert the robot program into a second sequence of tokens representing data for motions and actions contained in the robot program. A modification command generator is adapted to compare the first and second sequences of tokens and based thereon generate modification commands. The first converter is adapted to receive the modification commands and edit the graphical program based on the modification commands so that the token sequence of the graphical program matches the token sequence of the robot program.

Abstract: A method for non-contact determination of sought properties of an object to be measured by using electromagnetic induction. An electromagnetic field is generated in a transmitter coil placed on one side of the object to be measured. The magnetic field penetrates through the object to be measured and is detected by a receiver coil placed on the other side of the object to be measured. A control coil is placed near the transmitter coil generating a change in the magnetic field of the transmitter coil. A field change in the detecting is detected in the control coil. The field is detected in the receiver coil. The difference in time is determined for the detection of the field change in the control coil and in the receiver coil, respectively. The time of penetration through the object to be measured is determined, and the thickness or electrical conductivity of the object to be measured is determined therefrom.
Abstract: A method and system for a client application (1) to request a data item from an access server (3) in a computer controlled control system. The control system includes objects and a plurality of access servers, which said objects represent various entities that have a defined functional meaning in the control system. Each access server, such as an OPC server, may provide access to one or more real-time data, historical data, and alarm and event data items. In an embodiment the method provides means, which enables the Access Service Handler (2) component, by querying a said object, to obtain a reference for a desired data item, to find out which access server handles the said data item. The Access Service handler then makes request to the identified access server.
