How to Write & Transmit Ethernet Frames

No, using VISA will not help you bypass the TCP stack.  It will get you access to a raw TCP socket, but it sounds like that is not what you want.

Expecting some help from NI people, lot many labview users are struggling with this issue.

Hey D.S. 

Nathand is correct, you will not be able to bypass the stack using VISA.  To my knowledge there is no LabVIEW function that will allow you to do this.

So when NI is going to provide supporting toolkits for industrial communication protocols like, IEC 61850, IEC 101-104 etc. To use NI controllers effectively as RTU for power sector, these features are required.

Based on posts on this forum, it doesn't seem like there is a lot of demand for this to be built into LabVIEW - or at least, a search for "IEC 61850" turns up very few results.  However, while doing this search I came across a presentation suggesting that someone has managed to get this protocol working with RT: Toshiba Railway Substation Energy Asset Monitoring Using CompactRIO.  Also, a Google search for "IEC 61850 library" finds several vendors providing C source code or .NET libraries to support IEC-61850.  Either one could be integrated easily into a LabVIEW program (you would need to build the C code into a DLL, of course).

EDIT: I don't know if this helps you at all either - I'm totally unfamiliar with power protocols - but there's also the NI LabVIEW Driver for IEC 60870-5.

Thanks for updating, quite knowledgeable.
