Is there any embedded Ic that could get analog voltage and then convert to modbus protocol,actually i am using op amp to mesurfe diffrential voltage then i send it to an external modbus analog card then it is read by a plc.
It makes a lot of wiring for nothing, i would like to combine all op amps and modbus card on one pcb, i would only have a rs-485 communication on it.
I don't know if that exist?
