  • Page 2 IMPORTANT CUSTOMER NOTICE- OXYGEN SERVICE Sierra Instruments, Inc. is not liable for any damage or personal injury, whatsoever, resulting from the use of Sierra Instruments standard mass flow meters for oxygen gas. You are responsible for determining if this mass flow meter is appropriate for your oxygen application. You are responsible for cleaning the mass flow meter to the degree required for your oxygen flow application.
  • Page 3 Warnings and Cautions Warning! Agency approval for hazardous location installations varies between flow meter models. Consult the flow meter nameplate for specific flow meter approvals before any hazardous location installation. Warning! Hot tapping must be performed by a trained professional. U.S. regulations often require a hot tap permit. The manufacturer of the hot tap equipment and/or the contractor performing the hot tap is responsible for providing proof of such a permit.
  • Page 4 Receipt of System Components When receiving a Sierra mass flow meter, carefully check the outside packing carton for damage incurred in shipment. If the carton is damaged, notify the local carrier and submit a report to the factory or distributor. Remove the packing slip and check that all ordered components are present.

  • Page 6: Chapter 1: Introduction

    Chapter 1: Introduction This manual will explain how to add a Sierra flow meter 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’ InnovaMass 240i and 241i vortex mass flow meter with the Foundation Fieldbus Communication Interface to your network.

    Chapter 2 – Connecting the InnovaMass 240i/241i to your FF-BUS Network The InnovaMass 240i/241imeters use 24VDC (+/-10%) at 1.1 Amp. Due to the current needed, the meter cannot be powered from the H1 network. The separate 24VDC (+/-10%) power is connected to terminals 1 and 2. The Foundation Fieldbus H1 network connections are labeled as FF-1(terminal 13 and FF-2 (terminal 14).

    (input), it is still referred to as an AO Block. The 240i/241iFF-BUS interface has one, labeled 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, the user will only need a rudimentary knowledge of Modbus.

  • Page 9: Chapter 4 - Foundation Fieldbus Interface Configurations

    Chapter 4 – Foundation Fieldbus configuration The 240i/241iFF-BUS interfaces uses a Modbus to FF-BUS translator board inside the flow meter. This allows the user to configure variables accessible to our 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.

    Chapter 5 – Re-configuring the FF-BUS Using NI- FBUS Configurator The National Instruments F-BUS 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.
