<div class="markdown_content"><p>Hello,<br/> I have raspberry Pi (model 3B+ with Codesys 3.5.15.30) with one modbus master RTU (COM port 1) and with UBS to RS485 converter connected to one of raspberries USB port, so I can communicate with slaves on that bus.<br/> My question is can I add one more modbus master to new COM port (and add one more USB to RS485 converter) to communicate with other group of modbus RTU slave devices?</p> <p>Thank you in advance!</p></div>
