Recipe


Appendix B, Building a Recipe, further explains this feature of the 9220.

Pressing the Recipe button on the main status screen displays the recipe screen, which will allow the user to load an existing recipe and start it or see the currently running recipe.

The recipe screen shows the last program loaded into the program run buffer and its status.  If the program is running, the active step number is highlighted green.  When the step is highlighted green, then the recipe is running on that step.  When a step is highlighted yellow, the recipe is in hold on that step.  A red Acknowledge button in the bottom left corner of the screen displays an alarm condition.  Note – the main status screen will also show the recipe running status, as well as run time and remaining time for the step as well as the entire recipe.

 

The recipe screen has a total of seven buttons that will allow the user to load up a recipe, as well as control the recipe and acknowledge an alarm.

  • The Advance button will advance the recipe to the next step in the recipe.  The user will need to confirm the advance command.

  • The Hold button places the displayed recipe program in hold. Once a decision is made that affects the recipe, it may be continued by pressing the Resume button.  Note – When a recipe is put into hold status, the text on the Hold button will change to “Resume”.  When the step is started up again, the text on the button will change back to “Hold”.  When a recipe step is in a hold status, the step will be highlighted yellow.  The user will need to confirm the hold or resume command.

  • The Stop button stops the recipe program that is currently running. Stop means exactly that! It stops the program. It is NOT a hold button. See the description for the hold button above. To re-start the program if it has been stopped you must use the Load button, enter the recipe number, and then highlight the segment number of the recipe that you want to start with and start the recipe again.  The user will need to confirm the stop command.

  • The Soak button allows you to enter a new value for the time remaining in the current soak or ramp cycle only – future soak or ramp cycle times cannot be modified.  The step must be a soak or ramp cycle for a change in soak/ramp time to be adjusted.

  • The Acknowledge button will acknowledge the alarm.  In most cases, it will be acknowledging end of soak. The alarm must be acknowledged to allow the program to go to the next step.  Note – The Acknowledge button is only visible when an alarm condition is present.  Once the condition is acknowledged, the Acknowledge button will become invisible again.

  • The Load button allows the operator to enter the recipe number to be run and to view the recipe before pushing the Run button. Pushing the Run button starts the recipe. If a recipe program is running and the operator enters a new recipe program it can be viewed and modified. The recipe does not become active until the Run button is pushed. Pressing Run places the program currently being viewed in the active memory and will begin to run the new recipe.   To select the recipe to view or edit, click on the recipe number button in the top left corner of the screen.  This will display a screen where the user will be able to load up a valid recipe (range 1 – 300).  The program can be started in any step by clicking on the step number button next to the “Step” text and entering the new step number (range 1 – 24), and then pressing the Run key.

    Edit Recipe Step Screen
    While reviewing the program that is about to be run, each step can be modified.  Highlight a step number and click on the Edit button.  The opcode can be changed with the drop down list at the top.  This list can be sorted alphabetically by click on the “Alphabetical” checkbox.  The parameters of the opcode can be modified on this screen as well.  See Chapter 2 – TOUCH SCREEN MENU for details about each opcode.  Click on the OK button to accept the changes; click on the Cancel button to ignore the changes.  Note – Any change to the recipe is a one-time edit, and will not affect the recipe that is saved on the 9220 controller.  Click on the Cancel button on the Load Recipe screen to cancel loading a recipe and return to the main recipe screen.

  • The Return button returns you to the main status screen.
