Timer
The timer operates by counting down from a value specified by hours:minutes:seconds. When the timer
“runs out”, the Timer Event is triggered, and the timer is restarted at the specified value.
While Clock Events allow you to schedule recurring tasks based on fixed, regular calendar periods (daily,
weekly, etc,), Timer Events allow you to schedule recurring tasks based on user-defined time periods.
For example, a Timer Event may be triggered every 27 seconds or 36 hours.
Variable
A Variable Event is triggered when the value of a Variable matches a constant or expression. If the
“(expression)” check box is checked, then the expression defined by “Trigger value” is evaluated
whenever the Variable specified in “Origin” is modified.
Serial
Serial Events are triggered when the INPUT value at a specified port matches a constant or expression. If
the “(expression)” check box is checked, use the
“\g”
escape character (see
Escaping Special
Characters
, page
90
) to get access to the incoming serial data. Use a “Trigger value” of
“*”
(see
Wildcard Characters
, page
90
) to cause any incoming serial data to trigger the Event.
