Hi Mahesh,
It sounds like you are just getting started with using the
FP-PWM-520.
Since you are looking for rather general information I would recommend that you search ni.com for '
FP-PWM-520' and you should find plenty of relevant links.
Connection info can be found in the
Operating Instructions Manual which is linked off of the
Product Page. More general information can be found on the
DataSheet.
As with all other National Instruments products you can easily program
and control FieldPoint from LabVIEW. Don't forget to download the
latest version of FieldPoint (currently
NI-FieldPoint Version 4.1 for Windows 2000/XP).
These links and any other searches should help you find what you are looking for.
Regards,
