Raspberry Pi as Modbus TCP remote IO
I have a Schneider Electric STU, 3.5 in TFT LCD Touch-Screen HMI Display. It is modbus tcp compatible. I plan to do control via scripting on hmi, but would like to use the rasberry pi as a remote I/O via modbus tcp to be able to use the gpio as digital inputs/outputs to access them from the hmi.
Do you have a solution for this to use a rasberry pi as remote io?
Thank you

Re: Raspberry Pi as Modbus TCP remote IO
What you intend to do is possible. We have an example for UniPi which solves just that. You should be able to modify it for Raspberry Pi.
See the documentation:
And here is the mentioned example: UniPi as Modbus TCP slave
Hope this helps!
