Recently, I  purchased a Wells-Index 833 CNC mill which the previous owner started the conversion to  a new controller and DL2056 PLC.
The controller is a Galil DMC 2183 which I have working with Mach3.  
My issue is setting up the PLC over Ethernet Modbus for spindle control (FWD & REV).
While I can control the spindle thru the DirectLogic software, I'm have an issue tying it all together and working thru Mach3.
One of the reasons for the PLC is the previous owner created to analog panels. One of the panels has a MPG.

All help is appreciated.

Thanks,
Jeff
