1. Alternative:
Move to or from multiple step points
according to different transition conditions.
2. Simultaneous:
Move to or from multiple step points
according to one transition condition.
6. Jumps
- Allows movement to step points outside the sequenced order or even to
different program processes
1. The step points S10, S11 and S12 are
sequenced in order, and therefore can be
connected by using the common SFC
diagram. However, to return back to S0 from
S11 or S12, a Jump has to be used to
complete the transition.
2. To move from S20 within the procedure of S1
to S10 within the procedure of S0, a Jump
has to be used to complete the transition.
