Make Sense to add a Distance Offset!

Please don't use the GEN_ prefix for such blocks. The GEN_ prefix is used in Eclipse 4diac for configurable types (e.g., publish). Also distance is maybe not the best name as I could feed it any value to generate pulses.

Would RangeBasedPulse be better?

sorry, yes, normally i know this. 

 Also distance is maybe not the best name as I could feed it any value to generate pulses.

you are right. it might be Time, it might be Distance, or it might be any Value from any Source. 

e.g. generate Pulses dependent of a Sensor Value. 

Would RangeBasedPulse be better?

yes, will change
