METHOD AND APPARATUS FOR SAFELY DISCONNECTING AN ELECTRICAL LOAD |
摘要 |
A method and system for safely switching off an electrical load in a system comprising a multi-channel control unit, a single-channel data transmission path and an output unit having a first processing unit, a second processing unit and safe outputs. The method comprises receiving and evaluating an input signal by the multi-channel control unit and generating an enable signal based on the evaluation; transmitting the enable signal to the output unit via the single-channel data transmission path; receiving the enable signal by the first processing unit and generating an output signal based on the enable signal; providing at least one part of the enable signal from the first processing unit to the second processing unit for evaluation therewith; generating a dynamic clock signal by the second processing unit based on the enable signal; and controlling the safe outputs based on the output signal and the dynamic clock signal. |
