Serial comunication (RS232) with a Rockwell GV3000 VFD

[tauomega]

I am trying to control a Rockwell Automation GV3000 VFD using a serial connection.  Does anyone have any drivers that could do this?  Other possible suggestions?

Did u check MAX port configuration and status of the port?  i guess LV supports rockwell automation.,

Unfortunately it doesn't look like there are any instrument drivers created on the Instrument Driver Network (https://www.ni.com/en/support/downloads/instrument-drivers.html) for this instrument.

However, you should still be able to communicate with this instrument using LabVIEW, LabWindows/CVI, etc., with VISA. You can use VISA VIs (or function calls) with the serial port to communicate with the device. The commands you send will be based on the instrument. The instrument will have SCPI commands, ASCII strings that the instrument will respond to. This is something that should be included in a user manual from the manufacturer. There is an example in the LabVIEW Example Finder that shows how to do simple serial communication, called Basic Serial Write and Read.vi.

I hope this helps!

One more thing. does it need  a carriage return after sending commands on RS-232 port ?  if so use it and then see..i think it has to work ..
