The Analyzer Trigger Menu
Modifying the user macro
As more sequence levels are added, the timer status in the new levels
defaults to Off. Timers must be continued or started in each new level as
appropriate. When a timer expires or stops, its count resets to zero.
Branching
If either the less than or greater than duration is used, only the primary
branch is available. Otherwise, each sequence level except for the last has
two-way branching.
If the primary branch is taken, the analyzer goes to the next level. If the
primary branch is not found, the analyzer immediately evaluates the "Else on"
secondary branching term.
If the "Else on" term is found, the secondary branch taken is to the
designated sequence level. If the "Else on" term is not found, the analyzer
continues to loop within the same sequence level until one of the two
branches are found. If the "Else on" branch is taken, the occurrence counter
is reset even if the "go to level" branch is back to the same level. If both
branches are found true at the same time, the primary branch is taken.
Branching across the trigger level is possible. If this occurs, the sequence
level evaluation could loop without ever seeing a trigger term. Be careful in
designing your sequence instructions.
