Visa Communications protocols

[kwhitehead]

I'm looking for a list of Communication protocols supported by Visa. I'm not sure if that is a vague question or not but I thought that there would be a list of the different protocals that visa can support. Some specific ones are CAN Bus and Mod Bus. I saw some converstation about both but couldn't tell if the Visa driver supported these. Andy others supported by visa also?

I am also wondering about Field bus

Hello,

I was able to find a helpful article, which I think covers most of the questions you had.

 NI .NET Driver Support

http://www.ni.com/white-paper/14434/en/

The specific protocols which are encapsulated by NI VISA are the following:

NI-VISA .NET Protocol Support:

GPIB

GPIB-VXI

VXI

PXI

RS232

RS485

Ethernet (TCP/IP)

Remote NI-VISA

USB

NI-FBUS contains a Field Bus specific .NET API.

NI-CAN/XNET has a LabVIEW, CVI, and C/C++ API.  You can wrap these functions in .NET to allow for use in your application.

Unfortunately, NI currently does not offer a Modbus .NET API.  You should be able to implement this using TCP/IP, though.

I would recommend that you post this request on either the Measurement Studio or Additional NI Software Idea exchange pages. Our R&D department frequently adds new features from popular suggestions.
