Automate using a window script

A window script sets the operating conditions of the Liquid Fertilizer application while it is running in WindowViewer:

• When the Liquid or Concentrate valves are open and the Outlet valve is closed, the tank fills with ingredients.

• When the Liquid or Concentrate valves are open and the Outlet valve is open, the tank volume remains constant.

• When the Liquid and Concentrate valves are closed and the Outlet valve is open, the liquid fertilizer empties from the tank.

• When the mixing tank level is less than 1500 liters and the liquid or concentrate values are open, the tank begins to fill with ingredients.

• When is the tank level is greater than 500 liters and the outlet valve is closed, the agitator begins to rotate.

• When the tank level falls to less than 500 liters and the outlet valve is open, the agitator stops.

To create a window script

1. Right-click on a blank area of the Mixers window to show a shortcut menu.

2. Select Window Scripts from the shortcut menu.

3. Type or copy the following windows script into the Scripts dialog box.

   

   You can select the following script text if you want to copy/paste to the InTouch script editor.

   IF Tank_Level < 1500 AND (Valve_Liquid OR Agitator) THEN Tank_Level = Tank_Level + 20; ENDIF; IF Tank_Level > 500 AND NOT (Valve_Outlet) THEN Agitator_RPM = Agitator_RPM + 15; ENDIF; IF Tank_Level > 0 AND (Valve_Outlet) THEN Tank_Level = Tank_Level - 20; ENDIF; IF Tank_Level < 500 AND NOT (Valve_Outlet) THEN Agitator_RPM = Agitator_RPM == 0; ENDIF;

4. Set the Condition Type field to While Showing.

5. Set the Every field to a value between 500-700 milliseconds.

   The window script will run periodically at the interval you set in the Every field.

6. Select Validate to see if there are any errors in the script.

7. Correct any script errors and select OK.
