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 &#x201c;0&#x201d; and at the same time carrying out an interrupt test on the channel with logical &#x201c;1&#x201d;.

Diagnosis of redundant signal output channels connected in parallel

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.
