The following parts should be replaced periodically as preventative mainte-
nance. The procedures for replacing these parts are described later in this
section.
The battery retains the following data of the CPU Unit’s RAM when the main
power supply is OFF. This data will not be stable when the power supply is
turned OFF if a battery is not installed or the battery has expired its useful life.
At 25 C, the maximum service life for batteries is 5 years whether or not
power is supplied to the CPU Unit while the battery is installed. The battery’s
lifetime will be shorter when it is used at higher temperatures and when power
is not supplied to the CPU Unit for long periods. In the worst case conditions,
the battery will last for only 1.8 years.
• Check the new Unit to make sure that there are no errors.
• If a faulty Unit is being returned for repair, describe the problem in as

prior to remounting the Unit.
also all other data required for operation is transferred to or set in the new
CPU Unit before starting operation, including DM Area and HR Area set-
tings. If data area and other data are not correct for the user program, un-
expected accidents may occur. Be sure to include the routing tables,
Controller Link Unit data link tables, network parameters, and other CPU
Bus Unit data, which are stored as parameters in the CPU Unit. Refer to
the CPU Bus Unit and Special I/O Unit operation manuals for details on the
data required by each Unit.

cations Units, and other specific Units in a Memory Card as backup files.
A Memory Card and the simple backup operation can be used to easily re-
store data after replacing any of these Units. Refer to the CS/CJ Series
Programming Manual (W394) for details.
Replacing a Duplex Unit
(Duplex CPU, Dual I/O
Expansion System only)
Replacing an Expansion
Unit
(Duplex CPU, Dual I/O
Expansion System with
duplex Connection
Cables only)
Set the DPL Switch on the front of the Duplex Unit to
NO USE and turn OFF the power supply to the
Duplex Unit only.
Disconnect the cables to the Expansion Unit and
remove the Expansion Unit.
Note Before replacing an Expansion Unit, verify
that the cable to the other slot is functioning
properly.
