Branching
If either the < or > durations is used, only the primary "Trigger on" branch is
available, otherwise each sequence level has two way branching.
If the primary branch is taken, the analyzer triggers and 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 trigger levels is possible. If this occurs, the sequence level
evaluation could loop without ever seeing a trigger term. Care should be
taken in designing your sequence instructions.
Example
The following statement instructs the analyzer to find the bit pattern you
assigned to "a." If it finds "a," then the analyzer branches to the next
sequence level. If it doesn't find "a", the sequence evaluation immediately
branches to sequence level 3 .
