Abstract
A system for controlling and/or monitoring a control-unit group having at least two control units, a first control unit and at least one second control unit, the first control unit being designed for performing its control function and for monitoring this control function, as well as for monitoring the control function of the at least one second control unit.
Claims8
A system for at least one of controlling and monitoring a control-unit group including a first control unit and at least one second control unit, the system comprising:
- means, in the first control unit, for performing a control function of the first control unit, for monitoring the control function of the first control unit, and for monitoring a control function of the at least one second control unit;
- and
- a central emergency-operation signal line for triggering in the event of a malfunction of at least one of the first control unit and the at least one second wherein the first control unit is intrinsically safe and the at least one second control unit is not intrinsically safe control unit.
A method for at least one of controlling and monitoring a control-unit group including a first control unit and at least one second control unit, the method comprising:
- performing by the first control unit a first drive unit control function of the first control unit;
- performing by the first control unit a monitoring of the first control function of the first control unit;
- performing by the first control unit a monitoring of at least one second drive unit control function of the at least one second control unit;
- and
- triggering a central emergency-operation signal line in the event of a malfunction of at least one of the first control unit and the at least one second control unit wherein the first control unit is intrinsically safe and the at least one second control unit is not intrinsically safe.
A method for at least one of controlling and monitoring a control-unit group including a first control unit and at least one second control unit, the method comprising:
- performing by the first control unit a first drive unit control function of the first control unit;
- performing by the first control unit a monitoring of the first control function of the first control unit;
- performing by the first control unit a monitoring of at least one second drive unit control function of the at least one second control unit;
- wherein the first control unit is intrinsically safe and the at least one second control unit is not intrinsically safe.
A system for at least one of controlling and monitoring a control-unit group including a first control unit and at least one second control unit, the system comprising:
- means, in the first control unit, for performing a control function of the first control unit, for monitoring the control function of the first control unit, and for monitoring a control function of the at least one second control unit;
- wherein the first control unit is intrinsically safe and the at least one second control unit is not intrinsically safe.
