3 SPECIFICATIONS
• When Forced output manipulated value (MV) (buffer memory address: 205, 221) is
changed during forced output processing, the change is reflected to the manipulated
value (MV) immediately. (Bumpless shifting does not operate.)
• When Forced output command (buffer memory address: 204, 220) is changed to 0
(Forced output not commanded) during forced output processing, bumpless shifting
operates gradually changing back to the original operation by each control output
update cycle.
• The forced output function cannot be used during auto tuning. Even if Forced output
command (buffer memory address: 204, 220) is changed to 1 (Forced output
commanded), Forced output status flag (buffer memory address: 266, 522) does not
become 1 (Forced output not commanded).
• Even if Auto tuning start command (Yn4, Yn5) is turned on during forced output
processing, auto tuning is not executed. At this time, an error does not occur.

(4) Operation during program control
When Forced output command (buffer memory address: 204, 220) is set to 1
(Forced output commanded) while Program control run/reset (buffer memory
address: 57, 89) is 1(RUN), the module goes into a forced output status.
Meanwhile, the program control operation continues inside the module.
When the value in Forced output command (buffer memory address: 204, 220)
is set to 0 (Forced output not commanded), the mode returns to the program
control mode. The program control resumes operation that continued while
forced output was in execution.
