The Data Set tool is used to "push" data to another tool. Each data type has a specific set of data elements
that can be accessed. The Data Set tool can be used to access these data elements individually then link them
into other tools using its general property, Destination. When this tool runs, its data values are "pushed" into
the linked tool’s values. For example, if you set the data type to Integer, then set the value to zero, the tool
can be used to reset other tool values when it runs.
Delay
In the Logic Drawer
The Delay tool delays task processing for a user-specified number of milliseconds. Control panels can still
access data from the task during the delay period. The following inputs are available.
Event Scheduler
In the Logic Drawer
The Event Scheduler tool "fires" an event and sets the Event ID to the Event ID input property. All tasks that
have Scheduled Event selected as the task’s Trigger Event type are then queued for processing. Note: The
Impact device must be Online for the Scheduled Event to trigger any task.
Input Name What it is
numMilliseconds The number of milliseconds to delay. Actual maximum delay resolution is
four milliseconds.
Input Name What it is
Delay The number of milliseconds the system delays between tool execution
and when the event is "fired." Actual maximum delay resolution is four
milliseconds.
Event ID The identification number of this event. Use a Branch or Basic tool to test
it for selective processing.
In task A, when the
Event Scheduler tool
runs, it fires an event
with the Event ID = 1
Task B is defined with the
Task Trigger type of Sched-
uled Event. The Branch tool
checks for the Event ID num-
ber linked from the task level.
The ID matches so the tool
executes the True branch.
