maximum allowed cycle time. The MM-IM will still learn the expected cycle time, but by
using a suitable value in the CFG_SWG_LIMIT point, Sequence Running halted errors can be
overridden.
The common use for this is within applications that have some processing that takes
longer only some of the time. When the learning phase does not coincide with this longer
processing, Sequence Running Halted errors are seen.
As the limit in CFG_SEQ_LIMIT is a Straton point, its value can be updated dynamically if
desired. An example of dynamic updating would be increasing the value when the
application knows it will take longer, and decreasing when it will take a standard time.
The Sequence Running Halted error will only be set when the cycle time is greater than
both the learned value and the manually set sequence limit CFG_SEQ_LIMIT.
Highest Cycle Time
The highest cycle time is reported in the RES_SEQ_HIGH point within Straton, with an
embedded profile as a Medina analogue output. This can be used to determine if
CFG_SEQ_LIMIT has been set appropriately.
