Hello, I am trying to send and receive a custom message (array of bytes) via serial line 2 (Rs485 of a M241) which also uses the generic modbus slave. I've found this; https://help.codesys.com/webapp/_mod_lib_modbusrequest;product=core_modbus_configuration_editor;version=3.5.16.0 Is there an example how to use it? Kind regards, Jeroen
