ModBus and dspMC/IP
« on: November 19, 2011, 04:48:38 AM »
Is it easier to use one of the Vital Systems breakout boards (7535 PnP board) to control the spindle VFD via digital inputs on the VFD intelligent terminals or use the capability of the ModBus functionality of Mach 3 to control the spindle?

Using the VFD inputs via the 7535 works well for me on 2 machines. If you need to save a few I/O then the Modbus would be a good choice.

I am not sure which would be easier.

We never have the time or money to do it right the first time, but we somehow manage to do it twice and then spend the money to get it right.
