Abstract
(DE)

Kommunikationsgerät (30) zur Datenkommunikation in einem Industrienetzwerk (1) mit
– einer Eingabeeinheit (31), welche eine Information über einen aktuellen Fertigungsschritt empfängt, und
– einer Steuereinheit (32), welche eine Datenübertragung über das Industrienetzwerk (1) in Abhängigkeit von dem aktuellen Fertigungsschritt freigibt oder sperrt und/oder Übertragungsparameter in Abhängigkeit von dem aktuellen Fertigungsschritt festlegt,
wobei die Steuereinheit (32) die Übertragung von Daten im Rahmen von Verwaltungsaufgaben, insbesondere sicherheitsrelevanten Verwaltungsaufgaben, nur freigibt, wenn der aktuelle Fertigungsschritt keine echtzeitkritische oder verarbeitungstechnisch kritische Phase darstellt.

(EN)

The device (30) has an input unit (31) receiving information about an actual manufacturing step. A control unit (32) allows or blocks data transmission over a industrial network depending on the actual manufacturing step. The control unit determines sets (34a-34c) of transmission parameters such as static transmission parameters and dynamic transmission parameters, depending on the actual manufacturing step. A storage unit (33) i.e. RAM, stores the transmission parameters. The control unit determines whether a failure of data transmission is expected depending on the manufacturing step. Independent claims are also included for the following: (1) an industrial network comprising a monitoring unit (2) a method for controlling data communication in an industrial network.
