Detailed Function Description
The block is used to generate reset pulses from a reset button connected to I/O or from HMI. A rising edge on the HwResetInput or SwReset.In input generates PulseCount pulses on the Out output for the duration of Delay. The triggering inputs do not need to be returned to the inactive level; the block manages this automatically.
