Abstract: A method for controlling a system consisting of at least two control units, namely a first control unit and a second control unit. The system includes least one actuator and at least one sensor. The control units generate control data for the actuator on the basis of the information from the sensor. The method includes receiving, with the actuator, both the control data of the first control unit and the control data of the second control unit. The method also includes deciding, with the actuator, whether to use the control data of the first or second control unit to carry out an actuator function with the actuator.

Abstract: The invention relates to a method for operating a field device (1) for carrying out measurement and/or automation tasks in a wide-area automation network. The method comprises the steps of detecting the position of the field device (1) in the field device (1), generating a data set identifying the field device (1) and containing the position and a unique identification of the field device (1), transmitting the data set from the field device (1) to a server (10) of the automation network, assigning an identifier to the field device (1) identified by the data set, transmitting the identifier from the server (10) to the field device (1), and communicating in the automation network with use of the identifier. The invention additionally relates to a corresponding field device (1) and a server (10) for carrying out the method.

Abstract: The invention relates, in particular, to an automation system (10; 110), in which a programmable logic control device (20; 120) can be connected via a network (100; 200) to a database system (60; 160). So that the programmable logic control device (20; 120) can exchange data directly with the database system (60; 160), the programmable logic control device (20; 120) has a first driver module (42; 132) associated with a physical interface (50; 150) for controlling data transmission via the network (10; 110) and also a second driver module (41; 132) for controlling the data exchange with the database device (60; 160).

Abstract: The invention relates to a real time-capable control system essentially consisting of a software-implemented SPS application that exchanges the output data and input data by means of a field bus connecting module. The SPS application runs on a computer under the control of a non-real time-capable operating system, whereby the full functionality of the non-real-time-capable operating system is maintained. The real time capability makes the field bus connecting module ready for use, and the data are exchanged between the field bus connecting module and the SPS application via the host interface located inside the computer.
