Forcing a transition

You can force a transition to move the recipe to the next step without performing an Active Step Change. When forced, the transition fires as though the steps completed as expected. The forced transition sends a stop command and then a reset command to the previous step and then fires the transition.

Note:

The Stopping logic must be written to handle a stop at any point in the recipe. This is also true when performing an Active Step Change.

You can force a transition to execute only when the preceding step is in one of the valid states and in AUTO mode. In parallel branches, all preceding steps must be in one of the valid states and in AUTO mode.

A valid state is any of the following: Running, Holding, Aborting, Aborted, Stopping, Stopped, Aborted_NC, Stopped_NC, Held_NC, Complete or Active is also allowed.

A non-valid state is any of the following: Acquiring or Selecting.

Any user that has the Batch_Active_Step_Change key can force a transition.

To force the transition, select the transition and right-click. Select Force Transition from the context menu.
