Administering Convergences
If a step before a convergence is in the active status and its transition conditions are
met, the active status will be transferred provided that the step after the transition is
currently in the inactive status.
Procedures:
Adding a Convergence
Right-click a transition and select
Add Convergence
. Right-click an existing
convergence and select
Connections
-
Add Connection
, or right-click and select
Connections
-
Add Connection to Convergence
.
2-3-6 Simultaneous
Sequence
Divergences
A simultaneous sequence divergence is a program control structure for SFC, in which
two or more steps are connected after a single transition.
A simultaneous sequence divergence is represented by two horizontal lines.
A single step is branched into two or more steps, which are made active at the same
time.

Step 4
FALSE
Trans2
Administering Simultaneous Sequence Divergences
If a step before a transition is in the active status and its transition conditions are met,
the active status will be transferred to all the steps after the divergence at the same
time, provided they are all currently in the inactive status.
Following the transfer, all the steps immediately after the double line are
simultaneously made active, and are executed in order from left to right.
Procedures:
Adding a Simultaneous sequence divergence
Right-click a transition and select
Add Simultaneous Sequence Divergence
. To
make a simultaneous sequence divergence with three or more branches, right-click an
existing simultaneous sequence divergence, and select
Add Simultaneous Divergent
Step Branch
to add a branch.
2-3-7 Simultaneous
Sequence
Convergences
A simultaneous sequence convergence is a program control structure for SFC, in
which a single transition is connected after two or more steps.
A simultaneous sequence convergence is represented by two horizontal lines.
A simultaneous sequence convergence merges a process flow, which has been split
into two or more process flow (i.e. by a simultaneous sequence divergence).
