This procedure explains how to define basic process data for an instrument tag in the Process Data module. Although you usually create tags in the Instrument Index module, the ability to create tags in the Process Data module allows for efficient creation of complex analyzers, for example, stream and component tags.

  1. Do one of the following to open a tag in the Process Data module:

    • Create a tag.

    • Open a tag that you created previously.

  2. In the Process Data dialog, do the following:

    1. Select a fluid state.

      If you select N/A or Other, all fields under the General, Properties, Additional Properties and Base Conditions will open for editing, other than Fluid phase and Fluid name source, which will be disabled.

    2. If you are creating an analyzer, do one of the following from the Analyzer type list:

      • To create a simple analyzer, select Simple.

      • To create a complex analyzer, select Complex.

    3. Select OK.

      Simple analyzers belong to the Conventional Tag Class.

  3. If the Complex Analyzer Tag Manager dialog opens, define the complex analyzer. For details, see Define a Complex Analyzer.

  4. In the process data sheet for the tag that you opened, under Line number, select the line number to which the tag is connected.

    • If you confirm the prompt to copy the line data, all relevant line properties and data are copied to the tag process data sheet that you are editing.

    • If you selected a line that you configured for a complex analyzer, Smart Instrumentation copies the data from the Line Component table for that line into the ANALYZER / COMPONENT PROPERTIES section of the data sheet.

    For Control Valve operations do the following:

    1. Line number displays the main upstream line, select to view all available lines and select a different line.

      Changing the main upstream line will dissociate all associated lines (a confirmation message is displayed first). The

    Associated line then displays no lines.

    1. Select the Associated line (formerly having the name Downstream line) to display all the instrument's associated lines.

      When the upstream and downstream lines are different the Copy button is active to enable pressure drop calculation.

    2. Enter the remaining process data as needed.

  5. If you are defining a complex analyzer, link analyzer stream component tags with line components, see Link Analyzer Stream Components with Line Components.

  6. If you are defining a simple or a complex analyzer, in the ANALYZER COMPONENT / PROPERTY section, enter values and units of measure in the Repeatability, Accuracy, Minimum detection limit, and Range fields as needed.

  7. On the module toolbar, select Save Icon 16bit.
