Abstract:
Disclosed is a redundant control device, comprising a control assembly (A) further comprising an auto-diagnostic function; and another control assembly (B), further comprising an auto-diagnostic function, and which is made redundant with the control assembly (A). When one of the two control assemblies operates in an actual control assembly mode upon an object to be controlled, the other control assembly operates in an assembly mode that carries out auto-diagnostics, and the actual control assembly and the assembly carrying out auto-diagnostics are mutually interchanged such that both assemblies respectively carry out auto-diagnostics and diagnose regions whereupon auto-diagnostics could not otherwise be carried out when operating in control assembly mode.
