A method for controlling an electric machine or electric unit by actuating a component of the electric machine or unit using a predicate and by automatically examining the component in regard to the performance of the predicate to permit examination of an automated system for possible errors in a simply manner, wherein the predicate contains an expected value of a (physical) quantity of the component, and wherein in the examination of the component, a check is performed to determine whether the expected value actually arises when the predicate is performed such that erroneous situations can be detected by a runtime system without explicit programming being necessary therefor.

Method for controlling an electric machine and control device

A method for interchanging data between two devices in a network which utilizes a communication protocol with an interface based on an Object Linking and Embedding for Process Control Unified Architecture (OPC-UA) standard to interchange the data, wherein the communication protocol includes a priority allocation function which can allocate to the data at least two different priority values, and the data are interchanged based on the allocated priority values, such that the data interchangeable between the two devices in a predetermined period of time with a prescribed probability.

The user interface contains a project window ( FIGS. ) for interfaces (clips) of a programmable controller and programming windows ( FIGS. FIG. ) for each output interface of the programmable controller. Each such programming window ( ) contains a base node as a first graphical operating element ( FIG. ; FIG. ) for the output interface of the particular programming window and at least one additional node which serves as a graphical operating element ( FIG. ) for another interface (clip) or for a group of linked interfaces of the programmable controller. Each node has an output branch line ( FIG. ), the end of which can be routed to the base node or to another node by means of an operating means, such as a mouse. After the end of the output branch line is deposited on a respective other node, both a graphical link between the nodes and a controlsystem link between the interfaces which the nodes represent (FIGS. ) are produced. The user interface renders it possible even for users who have no experience with planning and design of controllers to produce a control program in a simple and error-free manner.
