A method for safely detecting in two redundantly-configured output modules a possible wire break of a load, wherein during a switch-off test of a first module, a current test is performed in the respective other module and a binary test is performed in the switched-off module. The binary test determines whether the voltage switched off through the respective other module is also reaching the module with the binary tests over corresponding connection paths.

Method for operating a redundant system and system therefor

A output assembly and method for diagnosing an electrical connection for reliably identifying a possible wire break to a load in redundantly connected output assemblies in which a control device for operating a switching device is configured such that the control device subjects the measured value to a test criterion, wherein satisfaction of the test criterion initially noted in the output assembly as a diagnosis fault, and the test criterion is applied cyclically within a time period comprising a waiting time, and wherein another output assembly performs a switch-off test during this time, thus allowing a statement to be made as to whether a wire break is present.
