  • Page 16: Transmitter Configuration

    Rosemount ships the transmitter with a temporary address of 126. To establish communication with the host, change the address to a unique value between 0 and 125. Usually, addresses 0-2 are reserved for masters or couplers; therefore Emerson recommends using transmitter addresses between 3 and 125. Note When shipped from the factory, Rosemount 644 PROFIBUS Profile 3.02 devices are defaulted in Identification Number ADAPTATION...
