If the wait band is set to OFF, the wait band will be treated as infinity and the
timer will measure time continuously after changing from RSET to STRT.
The following will occur if a power interruption occurs during execution of a
simple program:
• The program start (RSET/STRT) and RUN/STOP status from before the
power interruption will be held.
• The timer value for the Soak Time parameter will be reset.
Therefore, when a power interruption occurs, the timer value for the Soak
Time parameter will not be correct. In addition, if starting the program is
assigned to an event input, the event input status when a power interruption
occurs will be the program start status from just before the power interruption.
The following table shows operation when program operation ends, according
to the Program Pattern parameter setting.

(1) The bank number can be changed even during program operation by us-
ing either an event inputs or key operation.
(2) The bank number is initialized to 0 when the program pattern is changed.
Display at the Program End
When the program ends, the process value will be displayed on the No. 1 dis-
play (see note) and the set point and "end" will be alternately displayed on the
No. 2 display at 0.5 s intervals.
One of the following displays: PV/SP, PV only, or PV/MV.

Program End Output
When the Program Pattern parameter is changed from OFF to STOP, CONT,
or LOOP, the Auxiliary Output 1 Assignment parameter will automatically be
set to the end output. Conversely, when the Program Pattern parameter is
changed from STOP, CONT, or LOOP to OFF, the Alarm 1 Output Assignment
parameter will automatically be initialized to ALM1. The output assignment
parameters can also be used to assign the program end output to any output.
A program end output is also provided in communications status.
Clearing the Program End Status
The program END output and display will be cleared when the Program Start
parameter is changed from STRT to RSET. The setting is changed from STRT
to RSET while the Program Start parameter is displayed.
