I am looking for a freelancer who can help me with Raspberry Pi RS-485 connectivity for my industrial automation project. The ideal candidate should have experience in developing similar projects. Intended Purpose: - The RS-485 connectivity is intended for industrial automation. Sensors: - The type of sensors that will be monitored is energy meters (Modbus protocol). Number of Devices: - There will be 6-10 devices connected to the RS-485 interface. But for this task we just need to read data from a single sensor. Skills and Experience: - Experience in developing Raspberry Pi projects. - Knowledge of UART/RS-485 connectivity. - Experience in industrial automation projects. Specific Roadblock currently facing: I'm using this board: CM4-ETH-RS485-BASE-B from Waveshare Board specs: [login to view URL] Wiki: [login to view URL] It has four RS-485 ports. Able to see them (ls /dev/tty*). Able to write to them (TX) but not able to read (RX). The board is configured in Semi-automatic mode (using a hard soldered 0R). So we need to be able to switch b/w send and receive modes. Or put one port in Send, the other in Receive and connect these two ports to RS-485 loop (containing 1 sensor)

Hi. I have done a similar project on freelance.com. Here goes the details. The controller was a SIEMENS iot2040 gateway. I connected an AcuRev 1312 DIN-Rail Power Meter via modbus TCP. For your project, I have some tools to test the modbus connectivity between energy meter and Raspberry pi. I am open to discuss details over chat. Thank you.
