User Timers
The Controller features ten User Timers. These timers can be used to
implement timed operations not otherwise implemented by the controller.
The User Timers can be set in 0.1-second increments to 655.3 seconds
(slightly less than 11 minutes). When a timer times out, an event macro is
executed to perform a user-defined operation.
The User Timers can be operated as “one-shot” timers or as “retriggerable”
timers.
• One-shot timers are timers that are started and will time to completion.
Even if the start command is executed again, the duration of the timer will
be measured from the first start request:
• Retriggerable timers are timers that are started and can be restarted during
their programmed time. When retriggerable timers do time out, the time
period will be the full programmed time from the last restart command:
