4.5 Sequence Operation
BP4610
4-32
Sequence loop
Sequence loop also allows the entire sequence or any step block within the sequence to be looped.
This is achieved with [Jump step] and [Jump count] specified for each step. A jump counter for
counting the number of jumps is held internally for each step, so multiloop is also possible.
Figure 4-16 shows the loop specification method and the step transitions.
Step4
• [Jump step] 0
• [Jump count] NoCare
Step5
• [Jump step] 0
• [Jump count] NoCare
Step6
• [Jump step] 5
• [Jump count] 10
Step7
• [Jump step] 4
• [Jump count] 3
Specified count (10 times)
Go to [Jump step].
Specified count (10 times)
After jump, go to the next
step number.
Specified count (3 times)
Go to [Jump step].
Figure 4-16. Loop Specification Method and Step Transition Example
[Jump count] indicates the number of times jump is to be performed. Therefore, the loop count is equal
to the jump count + 1.
In the above example, the jump count is specified as “10” in Step 6, so the number of times Step 5 and
Step 6 are executed is 11.
