    Totalizer Blocks: The TOTALIZER block integrates (accumulates) the rate (i.e. Flow rate) to the corresponding integral. For example the ST100 offers two ways of providing the Totalize output of the Flow Rate; the FCI internally calculated “TOATLIZER” , or the PA Totalizer Function Block. The user can choose one or the other.

  • Page 8: Acyclic Operation Description

    ST100 Series Profibus PA When configuring the ST100 it is very important to follow the Slot sequence described below. If a module is not needed make sure to load an “EMPTY MODULE” in its place. In the example above the two “EMPTY_MODULE” modules are taking the place of the PRESSURE AI that is not offer in this model, and the profile TOTALIZER.

  • Page 9: System Blocks Description

    ST100 Series Profibus PA System Blocks Description Physical Block Parameters This block contains general PROFIBUS PA instrument information. This information helps to identify the device in the network, it’s software version, hardware version as well as control some of it instrument level functions.

    It also allows the user to change flow type from Volumetric, Mass Flow, and Velocity. This block also allows activation and deactiva­ tion of the ST100 FCI TOTALIZER. And finally for the multi-point models of the ST100, this block allows viewing of each individual sensor variables for the purpose of troubleshooting.

  • Page 11: Transducer Blocks Description

    ST100 Series Profibus PA Transducer Blocks Description There are 3 Process Data Transducer blocks in the ST100, one for each of the process variables that the ST100 can measure, flow, temperature, and pressure. Note: Not every process variable is available in every ST100 model.

  • Page 13 The ST100 has the totalizer function built in. This function is made available through the PROFIBUS PA protocol in addition to providing the PROFIBUS PA profile TOTALIZER. When needing a TOTALIZER function, FCI recommends the use of this TOTALIZER function.

  • Page 14: Analog Input Blocks Description

    ST100 Series Profibus PA Analog Input Blocks Description There are 4 AI blocks; three of those blocks will be described in this section the fourth one will be described in the Totalizer Blocks Description section. The three blocks described in this section are Flow, Temperature and Pressure.

  • Page 17: Totalizer Blocks Description

    Totalizer Blocks Description The ST100 PROFIBUS PA offers two ways of getting the totalized value of the flow for Volumetric and Mass flow. The FCI Internal TOTALIZER is computed internally by the ST100 system. The other TOTALIZER is computed by the PROFIBUS PA profile TOTALIZER module. The recommended TOTALIZER module to use is the FCI internal TOTALIZER.

  • Page 18: Profibus Pa Profile Totalizer Block

    ST100 Series Profibus PA PROFIBUS PA Profile Totalizer Block This function implements the PROFIBUS PA Profile specified TOTALIZER function. For additional information see the PROFIBUS PA standard. Totalizer Analog Input Block This block takes the input data from the Process Data Transducer Block, selected by the “Totalizer Average Channel” and makes it available to other function blocks at its output.

  • Page 19: Configuration

    Configuring Process Parameters in the TB modules The “Flow Transducer TB “ and the “Totalizer (FCI) TB” have a number of process related parameters that can be set within them. Theses parameters include “Pipe” size under the NOMINAL_SIZE parameter; three flow engineering unit types and the ability start and stop the ST100 internal FCI TOTALIZER.

  • Page 20: Configuring The Ai Blocks Of The St100 Instrument

    ST100 Series Profibus PA Configuring the AI blocks of the ST100 Instrument The AI blocks are the ones that make the process variables available to the cyclic DPV0 layer of the PROFIBUS protocol. They are use to configure and set the way that the process data is presented. Each one of the AI blocks has been preset to the designated Transducer Block channel, and the default prescribed by the profile.

    TOTALIZER_STATE: This parameter is used to turn the FCI internal TOTALIZER on or off. To turn the TOTALIZER on a value of 1 needs to be entered. To turn the TOTALIZER off a value of 0 needs to be entered.

  • Page 22: General Station Description Files

    There are two GSD files provided in the accompanying CDROM. The first is the Profile 3 specific file created by the PNO; which is the International PROFIBUS Organization, and all profile compliant instrument must meet. The second file is a FCI specific GSD file. This file supports features that are unique to the ST100 Flowmeter.
