Hi there, I am new to this forum but I have spent a bit of time looking for a sketch for an arduino to allow me to use it as a modbus interface.

When I have been reading posts there seems a lot of people say how they have everything working but I can not see a working example.

I have downloaded Shilling's code, altered it to work on the new IDE but could not get it to talk to the Mach software

I have downloaded zafarsalam's code and the FRO / spindle works fine but no digital inputs or outputs. I also followed mrprecise44 tutorial on how to alter zafarsalams code to use inputs, this sort of worked it took the inputs in as a holding register and I could not get it to act as a switch in brains.

I would really appreciate if someone could help me, I would realy like digital inputs and outputs , 0-5v out and 2 0-5 in. I am wanting to use either a arduno uno or mega,

I would like the arduino code and a sample of the brain and the modbus setting.

Again I would really appreciate some help with this
