To define exit conditions, follow these steps:

1. Drag a Condition Definitions shape from the LonPoint Scheduler stencil to

your LonMaker drawing.

2. Double-click the Condition Definitions shape. A drawing of the shape opens

in a new window.

3. For each exit condition definition, click an entry in the Exit Condition

column and type an Exit Condition name. Then click an entry in the
Definition column and type an Exit Condition expression. Close the Exit
Condition shape drawing window.
