State Analyzer Sequencer with Four States
Each state, except for the last, has two branch conditions. These are
the sequence-advance and sequence-else specification. (The
trigger-on specification is a special sequence-advance specification
that is described in the section “TRIGGER On Specification.”)
Sequence-Advance Specification
The sequence-advance branch, sometimes called the “if” branch or
primary branch, always branches to the next higher-numbered state.
You can specify the following kinds of sequence-advance
specifications:
Find (or Then find) "<TERM>" <OCCURS> time(S)
Find (or Then find) "<TERM>" <TIME PERIOD>
If the Find (or Then find) “<TERM>” is found <OCCURS> number of
times, the sequencer advances to the next sequence level.
If the <TERM> remains stable for <TIME PERIOD>, the sequencer
advances to the next sequence level.
A sequence-else specification can
branch to the same state...
to a previous state...
or a later state.
Sequence-advance
specifications always
branch to the next state.
Each state can have a
unique storage
specification.
