Phase Logic Configuration > Configuring the running logic for the FILL phase

Modify and add an action to the FILL running logic

  1. Double-click the step.
  2. In the S1 Properties dialog, enter the step description: Close outlet.
  3. Rename the step to CLOSE_OUTLET. (Click S1 in the step box to rename it.)
  4. With the CLOSE_OUTLET step box selected, select and right-click Step Actions View.
  5. Select Add to add an action.
    The Action Properties dialog opens.
  6. Enter the description (optional) as "Ensure that the color tank outlet valve is closed," leave the Type as Assignment, and leave the Qualifier as Pulse.
  7. Click Expression Assistant to open the Expression Editor.
  8. Click Insert Alias. Browse under Tanks → COLOR for the desired alias.

    Note that COLOR_OUT_VLV may appear in the Browse list as both a module block () and a simple alias (). Double-clicking the module block lets you browse to the module parameter for VALVE_SP, whereas selecting the simple alias allows no further browsing.  The first part of the expression should be defined as shown in the following: 

    '//#COLOR_OUT_VLV#/VALVE_SP'
  9. Next, click the Assignment button or type := .
  10. Then, click Insert Named State. In the Browse dialog, select the valve setpoint named state (vlvnc-sp) and the state of CLOSE.

    The completed expression now appears in the Expression Editor: 

    '//#COLOR_OUT_VLV#/VALVE_SP' := 'vlvnc-sp:CLOSE'
  11. Click Parse to check the expression.
  12. If the parsing completes without errors, click OK. Otherwise, correct the expression as needed.
    The expression now appears in the Action Properties box.
  13. Click OK.
    The action text appears in the Step Actions View. 
  14. Rename the step action, A1, to CLOSE_OUT_VLV.
