ONLINE EDITING OF RECIPE AND PRODUCT PARAMETERS

Changes made to a running RECIPE will affect

all

PRODUCTS using that RECIPE!!

Click the

Edit online icon

on the icon bar on top of the main screen. This is the icon towards the right of the

screen with a pencil image, which toggles edit online mode on and off.

The edit online icon will appear as depressed on the screen while edit online mode is active. In edit online

mode, the mouse cursor shape changes to a pencil when moved over one of the oven parameter set points that

can be edited. Left click the mouse when the pointer shape is a pencil to open an edit window to modify the set

point at the cursor.

set point value can be entered in the edit window, and this value is validated against the parameter's set point

boundaries when the

Apply button

is clicked. Click the

Apply button

to validate the entered set point value. If

the entered set point value is within the parameter's set point boundaries then it is sent to the oven controller,

which modifies the current oven process. Otherwise an out of boundary error message is displayed, and the

entered value is ignored.

IMPORTANT

Set point changes made in edit online mode are only sent to the oven controller, and are

temporary until the changes are saved to a recipe file. Online changes should be saved to a recipe

file once you are satisfied with the results. A prompt message to save changes is displayed when

edit online mode is terminated and changes were made.

Operator manual 17 August 2003

Heater parameters have an extra check box in the edit window to disable the heater. When a heater is disabled,

the oven controller disregards that heater all together, including deviation alarms. The heater disable status is

global, and takes precedence over heater set points in recipes. This allows an oven to continue operating with a

faulty heater until the faulty heater is replaced, without requiring modifications to individual recipes.

nother way to make online changes is to click on the product or recipe name at the bottom of the screen. This

starts the product/recipe editor, which allows the oven parameter set points to be changed. Click the

OK button

on the product/recipe editor to save the changes to the current product/recipe, and to send the changed

product/recipe set points to the oven controller.

If the recipe editor is closed by clicking the

close window icon

('x'), the exit without saving changes

confirmation dialog is displayed. The changes can then be saved by returning to the recipe editor and saving the

changes, or discarded by closing the recipe editor without saving the changes.

IMPORTANT

The save changes confirmation dialog is displayed when an action that modifies the current

oven parameter set points is initiated. If you decide to save the changes, the changes are saved

before the action is executed. An example of one of these situations is a stop/restart of the oven.

When you try to restart the oven, the save changes confirmation dialog is displayed before the

oven restarts (assuming edit online mode is active). This allows temporary oven parameter set

points in the oven controller to be saved to a product/recipe file, before new oven parameter set

oints are sent to the oven controller.
