How Conditions are Prioritized
Compact HMI will evaluate each condition in a linear order—from top to bottom as each
condition appears in the list of conditions in Compact HMI Editor. To change the priority of a
condition, simply use the arrow buttons (

will be the condition whose associated action is implemented.
• When all of the conditions in a single category are false, the setting associated with that
category will be set to the default.
