Jump sequence
When the transition becomes TRUE, the active state transitions to the specified step in the same block.
(3)
(1)
(2)
• There are no restrictions regarding the number of jump sequences.
• A jump sequence in the simultaneous sequence is possible only in the same branch. A jump sequence to another branch
within a simultaneous branch, a jump sequence for exiting from a simultaneous branch, or a jump sequence to a
simultaneous branch from outside a simultaneous branch cannot be created.
Ex.
Example of jump sequence that can be specified in the simultaneous branch
■ Precautions
Under the following conditions, a step cannot be specified as the destination of jump sequence.
• When a step at the position escaping from a simultaneous sequence is specified
• When a step at the position entering a simultaneous sequence is specified
• When a step immediately before the preceding transition is specified
• When current step is specified
When the transition (2) becomes TRUE while the step (1) is active, the step (3) is activated.
The step (1) becomes inactive. However, if it is a HOLD step [SC, SE, ST], the step holds the coil output
or action according to its attribute.
