Starting the SFC

Create a push button to start the SFC

This procedure explains how to use the DeltaV Operate interface to create a push button to start the SFC. Another way to assign the Start command to the push button is to select and right-click the push button, select Edit Script, and then edit the Visual Basic script for the Push Button object.

  1. On the DeltaV Operate Configure menu bar, click Insert → Push Button.
  2. Move the push button to a blank area near the link named FIC-101/MODE.
  3. Click the Text tool on the Toolbox and type the text to appear on the button: Start Discharge.
  4. Resize the push button to accommodate the text label. To do this, click the box and drag its handles.
  5. Select the push button and click the Task Wizard button on the toolbar.

    The Task Wizard dialog opens.

  6. Select Command as the Task Category and scroll down to Write Value to Tag Expert in the Tasks list.

  7. Click the Perform Task button.

    The Write a Value Expert dialog opens.

  8. In the FIX Database Tag field, type or search for:

    DVSYS. SFC-START/SP.F_CV

  9. Click Numeric and type 1 in the Value field.

    This command sets the value for the SFC to 1, which was defined to be the START value in the SFCCTRL named set.

  10. Click OK, and then click Close on the Task Wizard dialog.
  11. Save TANK101.
  12. Quit DeltaV Operate.
