    Dcs value is represented by two words. The first word contains the real pc/dcs value, the next higher word the corresponding status information. In the specification the term register word is also used instead of word. The filing of measured values in the temporary memory is always sorted according to ...

    Note: when transmitting the pc/dcs value in modbus-tcp protocol (measured value filing as 2 byte short), the decimal point is not transmitted, the value -0,5 bar is transmitted as -50. If the data format was selected in such a way that values outside the value range can be caused, limitation to the h...
