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.
