Retaining the End-of-Program State (Hold-mode End)
This function keeps the controller in the same state as when program operation was
completed.
When in hold operation, the controller retains its states of control output and event output.
To cancel hold operation, use either key operation or external contact input. When the hold
operation is cancelled, the control output is set to 0% or OFF, and the event output is set to
OFF.
To retain the end-of-program state, set the Junction Code program parameter of the seg-
ment in question to “1.”

Suspending the Progress of a Program (Wait Function)
When a running program moves from one segment to another, the wait function places the
program in a wait (stand-by) state, by using a wait zone and a wait time, until any deviation
is cancelled.
A wait zone is a deviation bandwidth from which the degree of PV input tracking is judged.
A wait time is the length of time that elapses until the PV input enters the wait zone. The
program progresses if the PV input fails to re-enter the wait zone within the wait time.
When the program is in wait state, the time setpoints of Segment Time and Time Event
parameters temporarily cease to be passed. At this point, the output based on the Time
Event parameter is retained.
