Actions (for Expression Rules) definition

(See the action reference for supported actions.)

Actions are the operations you want the Axeda® Platform to perform after evaluating the conditions (IF) for an expression rule. You can configure actions in the Then and Else expressions of an expression rule. The actions you can configure for an expression rule vary based on the type of trigger selected for the expression rule.

Actions are the functions supported for a trigger type. To configure an action for an expression, you add the action and then specify your information. For example, you may define the action GetData() for a Then expression, and specify that you want the Platform to get the value for dataitem "dataItemABC" over the last minute (60 seconds). This action returns an array of up to 100 values.

See the list of functions supported for Expression Rule actions.

Consecutive or Non-Consecutive

Actions can be run consecutively or non-consecutively for an expression rule. If an expression rule is defined with Consecutive actions, the actions are executed each time the expression evaluates to true. If an expression rule is not defined with Consecutive actions, actions are run only when the rule first evaluates to true and then they are not executed again until the rule evaluates to false and then to true again.
