Title: How to use Modbus data as axis data
Post by: aakici on January 06, 2014, 06:25:55 PM

I have a siemens s7-200 cpu 224xp connected to 2 rotary and 1 linear encoders. I send these data over modbus to mach3. I see data at brain control. How can i use these data as X, Y and Z axis data?

however i want to see encoder value with x axis value updated automatically

if i click on Load to DRO encoder value goes to x axis DRO.

How can i do encoder value automatically loads to X axis DRO?

Helps are appreciated.

You are trying to get a closed loop system. It's impossible.

Thank you for your reply. After reading manuals and visiting forum messages, i found that. Mach3 is not for closed loop systems. Now i am trying Linuxcnc.
