Communication between LabVIEW and a Variable Freqeuncy Driver (Inverter)

[berkayeryildiz]

Hello all,

I want to communicate with Siemens SINAMICS V20 VFD by using LabVIEW, serially. I want to use serial Modbus RS485 protocol and I cabled the inverter to pc. I need specific channel addresses of VFD V20 to create the read&write VI Block Diagrams for the protocol in LabVIEW. I communicated with the Siemens Supoort but it didn't work. I would be appreciated if you can help me.

Thanks in advance.

I am guessing you are asking for a Modbus register map?

Only the manufacturer of the device can give you this information.
