The following are the precautions for online module change.
(1)
Always perform an online module change in the correct procedure. A failure to do
so can cause a malfunction or failure.
(2)
If you resume control after setting the prerecorded values to the buffer memory of
the new module after an online module change, control cannot be resumed in the
same control status since the manipulated values (MV) (buffer memory address:
D
to 10
) are cleared once at the point when control was stopped.
H

(3)
If an alarm occurred before an online module change, the same alarm will not
always occur at the resumption of control. For example, when a standby upper-
limit alarm has been set, a standby status will be established and no alarm occur
at the resumption of control after an online module change if the alarm occurred
before the online module change.
