Issue Details

I'm working with a MODBUS RTU device, and I want to know if LabVIEW is able to communicate with this MODBUS protocol.

Solution

Yes, you can use LabVIEW for Modbus RTU communication. 

In Modbus, the first layer is the application data unit, also known as, ADU, which is what most people consider to be the "type" of Modbus used. There are three different ADUs: ASCII, RTU (remote terminal unit) and TCP/IP. In this case, our LabVIEW DSC module (Modbus API) or our free Modbus library are able to create this communication as they use VISA functions at a very low level.
