In a method for securely connecting a controller for a machine or plant to a higher-level IT system, an integration layer is provided between the controller and the IT system, a controller image of the controller is generated in the integration layer, and the controller image is accessed from the IT system. The IT system thus always accesses the controller image rather than directly the controller. This prevents malware from gaining access to the controller e.g. via a network.

Method and system for connecting a controller for a machine to a higher-level IT system

A project navigator for displaying technological objects hierarchically on a display device, in particular on a computer, is provided. The technological objects are mutually interconnected and model a machine with cascaded synchronous control. The technological objects are selected by a user input facility. For a selected technological object, an associated input and/or output side connection tree for the technological object is then displayed together with further technological objects.

Project navigator for a hierarchical display of technological objects, storage medium and engineering system

In order to improve movement control in an automation system for movement control, profiles for movement control are freely defined via functions. Polynomial interpolations or spline interpolations are used for the defined functions, the interpolations being of a higher degree. The profile for movement control has a command variable and a secondary variable, at least one of which is time-based or position-related.

Automation system and method for movement control of at least one moveable machine element

A system for guiding movement of a movable machine element of a machine, such as a machine tool, production machine and robot, receives user input data relating to a travel movement of machine element and an optimization criterion selected from a robust travel movement, where a smallest number of natural frequencies of the movable machine element is excited, and a time-optimized travel movement, where from the natural frequencies of the movable machine element only those natural frequencies are excited that do not include a main natural frequency. The system then determines from the movement profile coefficients of polynomial functions and a position setpoint variable based on the coefficients. The travel movement of the machine element is executed in response to the determined position setpoint variable.

Method and control device for guiding the movement of a movable machine element of a machine

A method and system for controlling an industrial controller based on technology objects are disclosed. Technology object types may be loaded and instantiated into the run time system of a controller, thereby increasing the functionality and providing technological scaling of the controller. Technology object types may be loaded in the form of technology packages and a user may use the functionality of the invention directly in a user program.

Industrial controller based on distributable technology objects

Industrial controller based on distributed technology objects

A method for integrating a number of automation components into an industrial controller with a uniform running level model of the runtime system. The basic clock of the running level model is devised from either an internal timer, an internal clock of a communication medium, an external device or from a variable (TG) which belongs to the technological process (P, P).

Integration method for automation components

The invention relates to an automation system, wherein error reaction is improved. This is achieved by providing a method for the treatment of errors in a real time automation system, wherein at least one error reaction function is triggered by at least one processing error and/or access error. The improvement is achieved by providing a method for the treatment of errors using the error reaction function, and by providing a method for the treatment of errors in an automation system which has at least two levels of execution, wherein at least one error reaction function is triggered by at least one processing error and/or one access error on at least one of the other levels of execution.

Error tolerant automation system and method for error handling in a real-time automation system

The loadability of technology object types into a run time system of an industrial controller permits functional expansion of the basic system of the controller as well as technological scaling of the controller. The loaded technology object types are instantiable, and may be distributed, as needed. Technology object types may be loaded in the form of technology packages and a user may use the functionality of the invention directly in a user program with a separation between technological functionality and device functionality.

A configurable running level model of a runtime system for the control tasks of an industrial controller for cyclical machines is created in a simple manner, enabling the programming of the machine sequence to take place in a sequential program. The wait_for_condition command in this case enables a user to wait for any desired conditions and respond with higher priority in the program flow. User programs can be additionally loaded into the user levels of the running level model.

Programming of cyclical machines

The basic available command library of the run-time system (RTS-RTS) of a universal motion control (combined SPS/NC control) can be expanded dynamically and according to the user's specific requirements by loading technology packets TP (with corresponding technology object types TO). Thus, a dynamic scaling of a universal motion control UMC is possible. Due to a consistent integration and communication platform API, the functionality of extremely prepared technology packets TP can also be integrated into the control.

Universal motion control

Mechanisms for operating an industrial controller (S) equipped with a runtime system (RTS), in particular for production machines, which enable a user to wait in the program flow for any desired condition are provided, the program flow being immediately continued when the condition is satisfied and the program flow being stopped when the condition is not satisfied, until it is established that the condition has been satisfied, the priority of the checking for the condition being increased in comparison with the current task priority while waiting for the condition to be satisfied. When the condition has been satisfied, a defined program sequence is processed with high priority up to an explicit end, the old task priority being resumed after the explicit end of the program sequence.

Method of operating an industrial controller

An apparatus for and a method of operating an automation system. A processing unit subjects useful information which is received via a telegram to a user designated logic operation and drives an output channel in accordance with a result of the logic operation. The processing unit monitors a time sequence of process data transmitted with the useful information and drives the output channel only when the time sequence lies within predetermined tolerances. A monitoring unit monitors the processing unit and shifts the output channel to a safe condition as soon as a malfunction of the processing unit is detected. The output channel may include a readback channel which reads back a signal applied to the output channel whereby the monitoring unit compares the applied signal and the readback signal and shifts the output channel to a safe state if the applied signal and the readback signal differ.

Failsafe data output system and automation system having the same

A runtime system of an industrial controller has a running level model which has a plurality of running levels of different types with different priority. This stratification allows for minimization of the communication between the process controller and motion controller tasks. The running level model has a hierarchical structure with various running levels such as synchronously clocked levels, a user level for system exceptions, an event-controlled user level, a time-controlled user level, a sequential user level and a cyclical user level. Other prioritizing stratifications also may be provided.
