The HAL encoder module is designed to be the interface to an encoder.  
Its only
purpose is to provide the information from an encoder to EMC.  If you 
consider that
an encoder "encodes" some information, then you could say you need a 
"decoder"
to convert that info back to useful form.

But, you have to adapt to the common language used by others who employ this
technology.  I think the documentation adequately describes what this does.
