(9) Simultaneous Sequences (divergence)
After the immediately preceding transition condition is satisfied,
this makes all the connected steps active. (The number of
branches is a maximum of 5 columns).
(10) Simultaneous Sequences (convergence)
When all the immediately preceding steps are active and the
transition condition is satisfied, this shifts the active state to the
next step.
(11) Macro Step
A macro step corresponds to one macro program. When the
immediately preceding transition condition is satisfied, this shifts
the active state to macro program with the designated macro
number. When the transition advances through the macro program
and reaches the macro end, the active state is shifted to the step
following the macro step. A macro step is accompanied by a
dummy transition which has no transition condition (always true).
ssss = Step number (0-2047)
mmm = Macro number (0-127)
