Hello,
I am trying to communicate with an Intelligent motion MDrive 17 motor driver via LabView 7.0 Express. The MDrive is connected to my computor serial port via an RS-422 converter cable (I have limited LV experience). The motor will turn a lead screw which will move a probe tip back/forward.
I first tried communications through the LabVIEW <=> Serial.vi by writing the motor command strings in the appropriate front panel icon making sure I had the correct comm port selected, baud rate etc.... I continually received a "VISA error code bfff003e error" regardless of settings.
I then tried to establish communications using the Instrument I/O Assistant.vi write step sequence again making sure all the correct settings were choosen. I enter a motor string command and choose the "\r" as my termination character (something I was not able to select using the Serial.vi) and the motor shaft turns (executes the command), but I still get the same "bfff003e" I/O error???
Since I am a LabVIEW novice, I am confused as to why I cannot seem to get the Serial.vi to work and why get the same I/O error using the Instrument I/O Assistant.vi but I seem to have communication.
regards,
brian
P.S. Can I find example VI's of stepper moton control I can use/modify using serial communication on NI?
