object is nevertheless valid. Use the method

is indeed online at a given time. In case of ambiguity when looking for a range finder by logical name,
no error is notified: the first instance found is returned. The search is performed first by hardware name,
then by logical name.

a YAPI context

a string that uniquely characterizes the range finder
Returns :
a
YRangeFinder
object allowing you to drive the range finder.
