  • Page 6: Chapter 1: Introduction

    Chapter 1: Introduction This manual will explain how to add a Sierra flow meter or controller equipped with Foundation Fieldbus to your network. The Foundation Fieldbus interface allows access to all relevant data available in the flow meter. ® This manual is intended to document the configuration of the Sierra Instruments SmartTrak Series mass flow meters and controllers with the Foundation Fieldbus Communication Module.

  • Page 7: Chapter 2: Connecting The Smarttrak 100 To Your Ff-Bus Network

    Chapter 2: Connecting the SmartTrak 100 to Your FF-BUS Network ® The instrument power, 24 VDC (±10%) may be supplied via the DB15 connector (see SmartTrak 100 Instruction Manual, Chapter 4) or the lower terminal blocks on the FF-BUS Module. The unit uses more current than can be supplied by the H1 network.

  • Page 8: Chapter 3: Definitions

    Modbus: Modbus is another digital communication protocol and is only relevant here because the Sierra FF-BUS interface uses Modbus as an intermediary between the meter and the FF-BUS interface. For special configuration, you will only need a rudimentary knowledge of MODBUS.

  • Page 9: Chapter 4: Foundation Fieldbus Interface Configuration

    Chapter 4: Foundation Fieldbus Interface Configuration ® The SmartTrak 100 FF-BUS interface module uses a Modbus to FF-BUS translator board. This allows the user to configure most of the many variables accessible to the MODBUS interface. For the most part, the Modbus to FF-BUS translation is invisible to the end user unless they want to reconfigure the Transducer Block (TB) to access other Modbus variables.

  • Page 10: Chapter 5 - Configuring The Ff_Bus Using Ni-Fbus Configurator

    Chapter 5 – Configuring the device using NI-FBUS Configurator The National Instruments FBUS Configurator software is widely used for testing and configuration of FF-BUS devices. Consult your NI-FBUS Configurator manual for more information on this NI software (included in NI-FBUS help on the software). Before starting the NI-FBUS Configurator, you must import the DD using the NI-FBUS Interface Configurator Utility.

Flow SmartTrak (PV_1), Total (PV_2), Set Point Read (PV_3), and Factory Full Scale shown below. If you scroll down futher you’ll also see the static MODBUS_REGS_ values being read from the instrument.

In this example, we will give the SmartTrak a set point of 100. The mode must be in “Manual” to do this.

    3. Scroll back up to see PV_1, PV_2, PV_3, and PV_4 and you will see the flow rate is now 99.947, the accumulated total has increased, and the set point is now 100. Note: this assumes you have a gas source connected to the controller. Current Flow Rate Accumulated Total New Set Point...

    .500 to 2.00. It is useful for adjusting the calibration or correcting the reading for another gas. See the SmartTrak 100 Series Instruction Manual, Chapter 4 for more information on the use of the span and K-Factors. This value will be returned to 1.000, if factory defaults are reset. The data type used is a 32 bit float format, Byte order 1-0-3-2.
