I recall starting by installing libmodbus on a non-LinuxCNC PC and looking at the example "test" files. https://github.com/stephane/libmodbus/tree/master/tests From these I created a very small test file that only sent a device ID request command to my VFD. This allowed me to get the serial connection and VFD sorted out. (Actually, before that I assembled Modbus packets manually and sent them out the serial port, without using libmodbus) -- Kirk Wallace http://www.wallacecompany.com/machine_shop/ http://www.wallacecompany.com/E45/ ------------------------------------------------------------------------------ See everything from the browser to the database with AppDynamics Get end-to-end visibility with application monitoring from AppDynamics Isolate bottlenecks and diagnose root cause in seconds.
