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

Add a transition to the FILL running logic

  1. Move the termination icon to the bottom of the diagram and delete the connecting line.
  2. Drag a transition icon from the palette to the spot where the termination was.
  3. Rename the transition to OUTLET_CLOSED (to wait until the outlet valve is closed).
  4. Double-click the transition.
    The Properties dialog opens.
  5. Open the Expression Assistant. Delete the default condition of False, select Insert Alias, and browse in Tanks → COLOR for the alias COLOR_OUT_VLV/PV. 
  6. Type an equals sign (=) or use the button provided.
  7. To construct the right side of the transition condition, select Insert Named State, and browse for vlvnc-pv:CLOSED.

    The expression now reads:

    '//#COLOR_OUT_VLV#/PV' = 'vlvnc-pv:CLOSED'
  8. Click Parse to check  the expression and correct any errors.
  9. Click OK in the Expression Editor and Properties dialogs.
  10. Draw a line from the first step to the transition. The cursor automatically turns into an asterisk when it is in the correct position for drawing lines.
