9.4 Setting the Wait Functions
9.4.1 Program Wait at Segment End
Description
Program wait at segment end makes the program wait at segment end if PV has not
attained the target setpoint.
The program will advance to the next segment the moment that the measured input
attains the wait zone.
If the measured input does not attain the wait zone within the wait time, the program will
advance to the next segment the moment the wait time elapses.
• Operation when the measured input attains the wait zone before the wait time
elapses
From when the wait operation starts, if the measured input attains the wait zone, the wait
state is changed to the operating state and the program advances to the next segment.
During the wait state, the program timer is stopped, therefore the time event value is
held.
