Modbus communication with an automation direct GS2 AC Drive

[_Bryan]

Has anyone written any VI's to communicate with an automation direct GS2-41P0 AC Drive using modbus?  I need to ask the unit a few questions while it is running and possibly start and stop it.  I have started searching around and found the NIModbus VI's.  I just have not figured out how to modify them to suit my needs yet (I just started playing with this today).  So far it looks like Modbus might make my head explode, but I am hoping it is easier than it looks at first.

Hi Bryan,

I've never tried using modbus to communicate with that particular device, but if you have any specific questions I'll do my best to answer them.

Also, you may be interested to know that the AutomationDirect GS2 Drive is supported by our NI-OPC Server, which may be a more attractive alternative to modbus.  I highly recommend you take a look at the LabVIEW Datalogging and Supervisory Control (DSC) module (wihch includes NI-OPC Server) to see if it is something your application would benefit from.
