Sequence Monitoring
Timing of the Straton application is monitored and if each cycle starts to take longer, then
the Sequence Running Halted error bit will be set.
It achieves this by learning the cycle time during the first 10 minutes of operation. A
following 50 minute period allows limited internal adjustment of the maximum cycle time.
After this period then a cycle time above the learned maximum will set the Sequence
Running Halted error bit.
If at any point there is a cycle time that is long enough to be deemed to be an infinite
loop, the Sequence Running Halted error bit will be set. The learning phase is restarted
whenever the Straton application is changed.
Sequence Limit
To avoid spurious setting of the Sequence Running Halted error bit the cycle time can be
reported and an upper limit set by using the CFG_SEQ_LIMIT point. When the
CFG_SEQ_LIMIT point is added to a Straton application, its value will be used as a
