Hi Maesa, If you use instances declared in a FB function. Try to use a global instance of MB_clien like this: use a global DB to declare the "ModbusDataconnectParamClient" structure. This will fix your problem and when you download the project, it will not cause problem for MB_client function. hopeRead more
