Case 2)
S11
P110
S20
To specify the termination conditions for
S11 and S16 separately, place the
conditions in P111 and P116 and specify
two dummy steps, S12 and S17, as
shown
dummy step also requires a step
number and subprogram number. Also
specify a dummy transition condition,
which becomes always true, in P110.

10.3.8 Jump
A jump controls the execution of steps non–sequentially, together
with a transition.

· Specify a jump destination label (Ln).
· The step to which control is transferred (jumped) is activated.
· The jump destination must be within the same program.
· A jump cannot be performed from outside a simultaneous
sequence to within the simultaneous sequence, or from within a
simultaneous sequence to outside.
· A jump cannot be performed between parallel–branched paths.

When steps S4 and S5 are executed and the
transition P110 evaluates true, the program is
repeated from initial step S1.
