Hello, As the owis is connected to the pc via usb, so the only way i can think of is using VISA or i might be wrong. The part where i am stuck is i dont know where to begin with using visa or is there any other method which can be used.

A very quick Google search turns up the manual which has this section in it:
This shows that it's either controlled by actual RS-232 or by USB pretending to be a USB to RS232 adapter. Either way, in LabVIEW you should plan on using VISA in general and setting serial-specific settings when you do.
There's another section in the manual stating:
Note the part about LabVIEW tools being included. I suggest you track those down. At the very least they will be a starting point.

Hi,
we use Owis PS35 motion controller, too.
I can confirm we use those device driver VIs provided by Owis - they are based on VISA functions (as usually for COM ports)…
Using a real COM port allows us to control the Owis even from a cRIO. The device driver VIs look similar to this:
(set acceleration for selected axis)

Hello,
For OWISOFT3, They are providing the installer (Setup.exe) which containing the all the LabVIEW driver.
The LabVIEW driver they created by using the dll file (PS35.dll). The communication can be manage via COM port or ethernet.
The bunch of functional VI are in the library for control.
