•
The timer is reset at the beginning of every step unless the
sequence timeout continue flag is set in the Edit Sequence Step
panel.
•
Cannot be nested.
•
Does not stop during a Pause or Halt (including single-stepping).
•
A timeout will generate an event and the occurrence of this
particular event can be enabled to generate an interrupt so the
S/W can query the events to see which one occurred.
•
The continuous conditional loop will continue to branch unless the
termination condition is subsequently met, whereby execution will
advance to the next Sequence Step as usual. If it doesn’t, the user
can manually halt or stop the Sequence.
•
The sequence timeout can be used to generate an event to
indicate that a sequence step (or steps) has taken too long to
complete
Pattern Timeout
The pattern timeout timer is a real-time timer which can be used in a
sequence step that has a Pause:
•
In the Sequence Step, the
Handshake Modifier
can be set to the
Pattern Timeout.
•
The Timer starts when the Pause begins.
•
The Pattern Timeout Timer will generate an event when the timer
times out. The Pause will continue unless the termination
condition is subsequently met, whereby execution will resume. If it
doesn’t, the user can manually resume or stop the Sequence.
Pattern Delay
The two pattern delay timers are real-time timers which can be used in a
sequence step that has a Pause:
•
In the Sequence Step, the
Handshake Modifier
can be set to
Pattern Delay 1 or 2.
•
The Timer starts when the Pause begins.
•
A Pattern Delay Timer timeout will cause a resume to be
generated.
