i read a article about configureing Labview for communication with modbus I/O in NI developer zone, but it was written for Labview 6, how can I configure it with labview 7. it seems there are some difference. Thanks!
In both LabVIEW 6 and 7, you connect to modbus using Lookout Protocol Drivers (LPD) and then communicate to LPD using the tag engine of LabVIEW DSC or through DataSocket.
