The application that is not working uses calls to the modbus library to act as a master for an Eaton SVX9000 variable frequency motor drive. Read and write functions do not work and return a modbus code 11 exception error. I have been unable to find what this error means.
Other confusing factors:
This same Labview code works on other SVX9000 drives.
An older compiled Labview application works (most of the time) on this system. The development code for the compiled code has been editted and is not really available.
Anybody know what exception code 11 means?
Thanks,
Keith Tang
