A method for modifying control software of an automation system having a controller and a plurality of subscribers, where the subscribers are connected to the controller via a data bus and communicate via a data exchange, at least one subscriber is a software subscriber for modifying control software of the controller, and the software subscriber comprises a memory unit on which at least one modification instruction for modifying the control software is stored. The controller sends an individual query message to the software subscriber for querying the modification instruction, the software subscriber sends a response to the controller providing the modification instruction, and the controller verifies whether the modification instruction is compatible with the control software, modifying the control software according if the modification instruction is compatible with the control software, and discarding the modification instruction if not compatible with the control software.

Method for modifying a control software of an automation system

In a method for operating a device comprising an internal clock generator and an internal clock and being connected to a network, the internal clock is incremented by the internal clock generator. Moreover, the internal clock is synchronized with a network frequency of the network.

Method of operating a device, device and system
