I too will be using a Delta VFD-B with Linuxcnc sometime soonish, probably late this summer or in the fall. My plan is to try mb2hal first, and write a driver/component in C (using libmodbus) if that doesn't work. I would not use Classic Ladder for this. -- Sebastian Kuzminsky ------------------------------------------------------------------------------ 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.
