===== 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.
