Hello,
we have no free Counter on NI PXI card and don't want to buy another only due to adding 1 encoder signal (no high speed).
Do you know some reliable common ways how to acquire and process encoder signal by digital or analog input only (without using HW Counter) + LabVIEW software?
Thank you for your advices.

You could sample the signal with an analog input and process the signal to decode it. Most DAQ cards do not have a hardware timed DIO, but if you happen to have one you could do the same as with the AI except you won't have to change into boolean values.
IMHO, by the time you get all of that coded up, you will have spent as much money (with your time) as you would with an additional DAQ board.
