4.
Mount the terminal block that was removed in step 2 and latch the hook
that was released.
5.
Turn ON the I/O power supply.
!WARNING
Always turn OFF the I/O Unit's I/O power supply before performing online
replacement. In addition, if external power is supplied to the terminal block for
a Unit such as a Relay Output Unit or AC Input Unit, turn OFF that power sup-
ply before replacing the Unit. Not turning OFF these power supplies may
result in false output signals, false input signals, or electrical shock.
Note
(1) When a Unit withdraws from I/O communications during replacement, the
corresponding Slice I/O Unit Communications Withdrawn Flag will go ON
and the Communications Unit’s TS indicator will flash red.
(2) Before using the automatic restore function, the preparation for automatic
restoration (creating backup data and turning ON DIP switch pin 3) must
be completed. Refer to
2-3-2 Automatic Restore Function
for details.
(3) Only replace one I/O Unit at a time.
(4) Always replace the I/O Unit with the same model of I/O Unit. If a Unit is
replaced with a different model, there may be unexpected outputs and the
restore operation may not be completed properly.
(5) If the base block is faulty or damaged, turn OFF the power supply and re-
place the entire Unit. Even in this case, the I/O Unit’s parameter data will
be restored automatically if the automatic restore function is enabled
when the power is turned ON.

Unit Conduction Time Monitor
Function Overview
The total ON time (unit: 0.1 hr) of the Unit's internal circuit power can be cal-
culated and recorded.
A monitor value can be set in the Unit so that the corresponding notification
flag in the Status Area will be turned ON when the total time reaches the set
monitor value in order to notify the Communications Unit. (Bit 2 of the Com-
munication’s Unit’s Status Flags will go ON.) The total ON time can be read
with a Programming Device.
• Measured time: 0 to 429496729 hours (stored data: 00000000 to
FFFFFFFF hex)
