Error using MODBUS Library for LabVIEW

[Nileshv]

Hi,

I am using MODBUS Library for LabVIEW to communicate with a controller. I am trying to read 16 Holding Registers at one go. BUt I am getting following error

Code : -1073807298

Description : VISA Write in MB Serial Transmit.vi:10->MB Serial Master Query.vi:9->Untitled 1

I have tried changing the Mask Value in VISA Flush I/o Buffer ( found in MB Init.vi ) to different value, but with no effect.

I am attaching the png file of vi used.

Can anyone suggest me what might be the issue

Are you using a USB to serial converter?

I would like to mention that I am able to communicate through my Dot Net Software. Do there should be no issue of drivers. But then any more suggestions / solutions are welcomed...
