Die Prozessoreinheiten (4 bis 7) führen jeweils eine Gruppe (G1 bis G4) von Tasks aus. Auf verschiedenen Hardwareeinheiten (2, 3) ausgeführte Gruppen (G1 bis G4) von Tasks nehmen von einem gesteuerten industriellen Prozess (1) direkt oder indirekt die gleichen Eingangssignale (E1, E2) entgegen und ermitteln die gleichen Ausgangssignale (A1, A2) für den gesteuerten industriellen Prozess (1). Es geben jedoch nur die Tasks jeweils einer der auf verschiedenen Hardwareeinheiten (2, 3) ausgeführten Gruppen (G1 bis G4) ihre Ausgangssignale (A1, A2) an den gesteuerten industriellen Prozess (1) aus. Die auf verschiedenen Hardwareeinheiten (2, 3) ausgeführten Gruppen (G1 bis G4) synchronisieren sich miteinander über eine jeweilige Kommunikationsverbindung (14, 15). Die auf derselben Hardwareeinheit (2, 3) ausgeführten Gruppen (G1 bis G4) von Tasks tauschen paarweise miteinander über ein jeweiliges Paar von Zwischenspeichern (16 bis 19) Daten aus.

Automatisierungsvorrichtung mit virtueller maschine zur synchronisation und synchronisationsverfahren

Eine hochverfϋgbare Automatisierungsvorrichtung mit zwei oder mehr Teilsystemen (A, B) soll einfach realisiert werden können. Daher wird eine Automatisierungsvorrichtung mit einem ersten System (A), das mehrere miteinander kommunizierende Objekte (1A) und eine erste Objektverwaltung (2A) aufweist, sowie einem zweiten System (B), das mehrere miteinander kommunizierende Objekte (1B) und eine zweite Objektverwaltung (2B) aufweist, vorgeschlagen. Jede der beiden Objektverwaltungen (2A, 2B) ist jeweils auf einer eigenen virtuellen Maschine (4A, 4B) aufgesetzt. Zur Synchronisation (3) der beiden Systeme (A, B) ist lediglich ein Kopieren eines die erste Objektverwaltung (2A) betreffenden Speicherinhalts der virtuellen Maschine (4A) von dem ersten System (A) in die virtuelle Maschine (4B) des zweiten Systems (B) durchzuführen.

Tool holder with measuring apparatus

A tool holder is configured for rotation about a tool holder axis of rotation defining an axial direction. The tool holder, at one axial longitudinal end thereof, has a tool section with a tool-receiving formation for receiving a tool and, at the opposite axial longitudinal end, has a coupling section with a coupling formation for torque-transmitting coupling to a machine spindle of a machine tool. A measuring apparatus is configured for acquiring data relating to the operation of the tool holder. The measuring apparatus has a sensor, in particular an acceleration sensor, with at least two measurement axes. The two measurement axes are oriented substantially radially with respect to the tool holder axis of rotation.

Vorrichtung und verfahren zum steuern einer maschine mit codiertem und nicht codiertem programmcode

Es soll ein hochverfügbares System insbesondere für die Automatisierungstechnik mit einer plattformunabhängigen Diagnose realisiert werden. Daher wird eine Vorrichtung zum Steuern einer Maschine mit einer ersten Steuereinrichtung (1), mit der ein erster Programmcode (7) zum Steuern verarbeitbar ist, einer parallelen zweiten Steuereinrichtung (2), mit der ein zweiter Programmcode (8) zum Steuern verarbeitbar ist, und einer Synchronisationseinrichtung zum Synchronisieren der ersten Steuereinrichtung mit der zweiten Steuereinrichtung bereitgestellt. Der erste Programmcode (7) ist ein codierter Programmcode, bei dem Arbeitsanweisungen und/oder Datenstrukturen gegenüber einem zugrunde liegenden Quellcode (9) codiert sind. Der zweite Programmcode (8) ist ein nicht codierter Programmcode, bei dem Arbeitsanweisungen und/oder Datenstrukturen gegenüber dem Quellcode (9) nicht codiert sind. Die Synchronisationseinrichtung (3) weist eine Codiereinrichtung (12) auf, um Daten, die bei der Synchronisation kommuniziert werden entsprechend der Codierung des ersten Programmcodes (7) in Abhängigkeit von der Kommunikationsrichtung zu codieren oder zu decodieren.
