Abstract (en)
[origin: WO2022084161A1] The invention relates to a device (10) and a method (100) for controlling a safety-critical process on a technical plant. A first protected signal unit (12) and a second protected signal unit (14), which are connected to the safety-critical process (20) by input-output channels (18), are configured to safely communicate with one another on a logical level in order to control the safety-critical process (20). The physical connection is implemented via a mains supply (16).
