Abstract
A control device for controlling a machine or system includes a monitoring unit designed and configured to monitor the functional state of a second control unit such that, when the second control unit is in an activated functional state, by which the machine or system is put into a safe state, the monitoring unit connects at least one input means associated with the second control unit to a first control unit such that non-safety-relevant functions of the machine or system can be triggered by manual actuation of the input means, as long as the second control unit is in its activated functional state in which the input means is not connected to the machine or system as a proper safety switching means.

A control device for controlling a machine or system, the control device comprising:
- a first control unit which is designed as a non-safe technology and is configured to control at least one non-safety-relevant function of the machine or system;
- a second control unit which is designed as a safe technology and is configured to control at least one safety-relevant function of the machine or system;
- wherein the second control unit is connected to at least one input means associated with the second control unit as a safe technology, the at least one input means designed for manual actuation in order to trigger the at least one safety-relevant function;
- and
- a monitoring device designed and configured to monitor the functional state of the second control unit in such a way that, in an activated functional state of the second control unit by which the machine or system is put into a safe state, the monitoring device connects the at least one input means to the first control unit in such a way that, by manual actuation of the input means, non-safety-relevant functions of the machine or system can be triggered while the second control unit is in its activated functional state in which the input means is not connected to the machine or system as a proper safety switching means.
