Note
When the remaining segment time is decreased and the event action timer times out, the time
event is forcibly generated at that point.
Example in which the final SP is changed using the segment time ramp grade
setup method
The figure below shows the example in which both the final SP and the remaining
segment time are changed by changing the final SP using the segment time ramp grade
setup method.

Advancing Segments
During program operation, you can force the program to advance to the next segment.
You can advance the program using key operation on the program operation status
display, using the external contact input, or through the communication function.
When you advance the program at the segment currently in operation, the program
advances to the next segment. However, depending on the segment at which this
function is executed, the following operation may take place.
• When advance is executed at the last segment
The program operates according to the switching settings of the segment.
When set to [Local]: The operation enters local mode
When set to [Reset]: The operation enters reset mode (operation stop)
When set to [Continuous] or [Hold]: The operation enters reset mode (operation stop)
• When advance is executed at the repeat end segment
Repeat operation is started.
• When advance is executed at a segment other than those described above
The program advances to the next segment regardless of the segment switching settings.
• When advance is executed when the program operation is on hold
The hold mode is cleared, and the program operates according to the segment
conditions described above.
Program pattern end signal
When program control terminates normally (excluding forced termination), the
termination can be notified using contact output (also through communication function).
The contact output is turn ON for 5 s after normal termination.
