Hi Kumar,

I have a few questions that will really clear up a few things for me. Are you actually using Modbus or are you using the TCP functions in CVI? What are you trying to do, basically what do you want to be able to do? The actuall functions that you need to call should be in your device manual. Do you have this information?

We have a Modbus library for LabVIEW but we do not have one for CVI. Please reply with more information on what you are trying to do.

Why isn't there a Modbus library for LabWindows/CVI?
