There’s no driver to connect to Raspberry Pis. So there’s no simple solution. Some people have used python-based OPC-UA to move data. Others have used Ignition’s WebDev module to allow the RPi to push data to Ignition. There’s topics all over this forum:

A Pico doesn’t have any networking, so it will be near impossible.

The Arduino RP2040 Connect is based on the pico and has WIFI. You might be able to do MQTT there, but it won’t be easy

With an RP Pico W I was able to connect and read data using this Modbus Micropython library: [GitHub - brainelectronics/micropython-modbus: MicroPython Modbus RTU Slave/Master and TCP Server/Slave library](https://github.com/brainelectronics/micropython-modbus/tree/develop)
