    This bus cable connects all devices in parallel. The system’s information is transmitted digitally. The XNX gas transmitter supports most digital communication protocols (HART, MODBUS, Foundation Fieldbus, etc.) and a discrete output (relay).
  • Page 10 Signals T = Terminator FD = Field Device Figure 2: Fieldbus network with XNX transmitter and additional devices Foundation Fieldbus connections to the XNX transmitter are made through a pluggable terminal block on the Foundation Fieldbus option board, shown in Figure 3. A simulation switch (SW5) is included on the board to enable/disable simulation mode.

    Commissioning Install and configure the XNX transmitter before commissioning the Foundation Fieldbus option board. In the final stages of boot-up, warnings and faults may be observed until configuration, calibration, and reset activities have been completed. Configuration This section provides startup and operating details for the communication portion of the transmitter.

    This parameter is used to define the relationship between the measured process value (Sensor Transducer Block) and the output of the AI Block. XNX supports all linearization types. Setting this parameter to DIRECT will pass the Transducer Block information without modification (i.e., the AI output will be identical to the Transducer Block).

    A device descriptor (DD) file is required to interface with the XNX transmitter. The following screens, using an Experion system as a host controller, show some of the features of the Foundation Fieldbus interface for the XNX transmitter.

  • Page 18: Configuration

    Configuration All user settings of the XNX transmitter can be made either at the local user interface or over Foundation Fieldbus. The configuration menu simplifies setup of alarm levels as shown in Figure 6. Time, units, and other parameters can also be configured.

  • Page 19: Event History

    Event History The XNX transmitter maintains a record of all significant events, all of which can be accessed from Foundation Fieldbus interface. All alarms, warnings, and faults are recorded. Additionally, over 60 types of informational events are defined to record important transactions such as recalibrations or configuration changes.
