Abstract: The invention relates to a device and a method for testing for wire breakage with a redundant signal output. To ensure the most fail-safe output in particular of a digital signal, whilst at the same time supplying a diagnosis function, it is proposed that two digital output modules should be connected in parallel, in particular with a diode integrated in each channel. The diagnosis function is enabled by a driver, which, in the event of a target value for the digital signal of logical “1”, connects the channel with a logical “1”, while setting a channel connected parallel thereto briefly to logical “0” and at the same time carrying out an interrupt test on the channel with logical “1”.

Abstract: A control component and method for an energy management unit (EM) in an industrial automation arrangement which is configured to control one of a process, a subprocess and a system part of the industrial automation arrangement. Here, the control component is configured to detect the energy consumption of at least one part of the industrial automation arrangement, and the control component is configured to relate the detected energy consumption to at least one stored specification. The control component is also configured to generate a request for at least one automation component as the result of the relating operation. The control component is configured to transmit a message containing the request to the automation component and to receive an acknowledgement message from this automation component, where the request is directed to changing an operational state of one of the process, subprocess and system part that is controlled by the automation component.

Abstract: An automation component for an industrial automation arrangement, wherein the automation component is configured to control at least one system part, process or subprocess of the industrial automation arrangement. At least two different operating states are able to be alternately set for the at least one system part, process or subprocess, and the operational states which differ with respect to the respective power consumption of the system part, process or subprocess. The automation component is configured to receive requests for a changeover to one of the at least two different operational states, the automation component is configured to output acknowledgement messages in response to the requests, and the automation component is configured to output status messages relating to the activated operating state of the operational states.

Abstract: A method for the project engineering of an automation system is provided. An existing project is opened or a new project is created in a project engineering software tool. In this project, a station having a plurality of slots is opened or generated. A hardware catalog is opened, the hardware catalog including a plurality of hardware modules. At least one hardware module is inserted from the hardware catalog into the station. The station is saved together with the inserted modules. In the process one or more hardware modules can be combined to form a hardware packet. In order to insert the hardware modules which are combined in a hardware packet, the hardware packet is selected and, as soon as the hardware packet is integrated into the station, all the hardware modules contained therein are automatically allocated to free slots of the station.
