<div class="markdown_content"><p>Codesys can definately be a Master for both Modbus RTU and Modbus TCP/IP. I'm not sure about Modbus RTU over TCP though. If you have the time and the physical hardware see if it's just Modbus TCP/IP. </p> <p>Do you have a part number or manual for the weighing module?</p></div>

<div class="markdown_content"><p><strong>Hello</strong>,</p> <p>I would like to ask for your help.</p> <p>I will have a weighing module which supports <em>Ethernet</em>, <em>RS232</em>, <em>RS485</em> interfaces.</p> <p>I would like to use MODBUS communication protocol which the device supports as follows.</p> <p>• RS484 - RTU (device interface RS485, frame RTU),<br/> • TCP/IP - RTU (device interface Ethernet, frame RTU),<br/> • TCP/IP - Open ModBus (device interface Ethernet, frame Open Modbus).</p> <p>So my question is whether I am able to communicate with this device using CODESYS runtime (acts as a Modbus master).</p> <p>I really appreciate your help.</p> <p>Thanks in advance.</p> <p>Best Regards!</p></div>
