<div class="markdown_content"><p>Hi,</p> <p>I would like to create a Modbus RTU Channel dynamically, without graphical Modbus Configurator.<br/> I created 'Modbus_COM' / 'Modbus_Master_COM_Port' / 'Modbus_Slave_COM_Port' in my codesys project, but channels are defined in a configuration file, so they will be created in the program.<br/> If it's possible, how can I do that ?</p> <p>If not, I also tried ModbusRequest function, but it doesn't work (MB_ErrorCodes = 255).<br/> Have someone an example of this kind of project, and explanations of how function is used ?</p> <p>Thank you,</p> <p>Rémi</p></div>
