NX Unit Configuration
CPU Rack
The CPU Rack consists of an NX-series NX1P2 CPU Unit, NX Units, and an End Cover.
Up to eight NX Units can be connected.
Configuration Remarks
NX-series NX1P2 CPU Unit One required for every CPU Rack.
End Cover
Must be connected to the right end of the CPU Rack. One End Cover is provided with
the CPU Unit.
NX Unit
Digital I/O Unit • Up to eight Units (including System Units such as Additional I/O Power Supply Unit)
can be mounted to each Expansion Rack.
• For the NX Units connectable to the CPU Unit, refer to the Ordering Information
page.
• You cannot mount NX-series Safety Control Units on the CPU Unit and use them.
Use NX-series Safety Control Units as a subsystem on EtherCAT.
• Refer to the NX-series Data Reference Manual (Cat. No. W525. Revision 11 or later)
for information such as restrictions on the NX Units.

Battery
The battery is not mounted when the product is shipped.
To turn OFF the power supply to the equipment for a certain period of time by using the clock data for programming, event logs, etc., you need a
separately-sold battery to retain the clock data.
The following describes the purpose of the battery mounting, the battery model, and the battery-related error detection and clock data settings.
Purpose of the Battery Mounting
The battery is used to retain the clock data while the power is not supplied to the CPU Unit. The clock data is retained by the built-in capacitor
whether the battery is mounted or not, but the retention period depends on the continuous power-ON time of the CPU Unit, as shown below.
* This is equivalent to the time to charge a built-in capacitor in which no electric charge is accumulated.
When you use the clock data for programming, use a battery if you cannot ensure the continuous power-ON time shown above or the power-OFF
time is longer than the above power-ON time.
The following data (other than the clock data) is retained in the built-in non-volatile memory, so they are not lost even if the battery and built-in
capacitor are fully discharged.
• User program
• Set values
• Variables retained during power interruption
• Event logs
Battery Model
The table below shows the model and specifications of the battery that can be used.

Refer to the NX-series NX1P2 CPU Unit Hardware User’s Manual
(Cat. No. W578) for details.
The clock information is retained during power interruptions.
