Modbus / Where to start
« on: May 18, 2022, 01:42:56 AM »
Hello -
My final goal is to read the current XYZ positions in Mach 4 through Modbus TCP. I have written programs to read and write data via Modbus (although I will have to brush up on it) so that part doesn't scare me. Concerning Mach 4, I don't know what I need to know.
I fumbled through the Modbus plugin dialog but was expecting a screen where I could say something like "this address contains this data, and by the way it is a float". I looked for some documentation on the Modbus plugin but didn't find anything.
Can you please point me in a direction to get started? Is there documentation? Are there examples similar to what I want to do (read positions from Mach 4)?
Thanks for your suggestions!
