Thank you........using modbus through classic ladder is all I want to 
do......I have the hardware and all I need is a way to patch it through 
classic ladder. My plan is to use the Motenc Lite I/O points for timing 
critical functions such as home switches, E-Stop and Overtravel Switches and 
the like and use modbus I/O points through classic ladder for operator push 
buttons for mode and jog functions. Weather EMC actually looks at the modbus 
points is not an issue as I can use classic ladder outputs to feed signals 
to EMC. I plan to use only digital I/O through modbus so if anyone can get 
classic ladder to read modbus I/O the rest would be easy.......This would 
give us almost infinite (relatively speaking) I/O. The device I have worked 
well in Mach3 so it should'nt be an issue. It also works with the stand 
alone version of Classic Ladder. It is a Cubloc CB290 from Comfile 
Technology. Look it up, It is pretty slick.
