You could open the created DB and drag data members to the corresponding location of MB_COMM_LOAD and MB_MASTER.

Hocam merhabalar, Modbus ile 40001 ve 40002 holding Register adreslerinden int veri tipine değer okuyorum bu okuduğum değerleri nasıl birleştirip DINT veri tipine dönüştürürüm ? Yardımcı olursanız sevinirim.
