The Analog I/O Option Board allows inputs from devices such as variable resistors, process-control
sensor, and inverter control.

Battery-free Operation
The following data (other than the clock data) is retained in the built-in non-volatile memory.
• User program
• Set values
• Variables retained during power interruption
• Event logs
The retention period for the clock data is limited
*1
.
When the clock data is not needed or the equipment’s power OFF time is shorter than the clock
data retention period, the battery-free operation is possible and man-hours for battery replacement
can be reduced.
If you turn OFF the power supply to the equipment for a longer period of time than the clock data
retention period, mount a battery which is sold separately.
*1. Approximately 10 days at an ambient temperature of 40°C. Refer to 3-1-5 Battery on page 3-18 for detail.

Standard-feature SD Memory Card Slot
You can access an SD Memory Card that is mounted in the CPU Unit from the user program.
l
Highly Reliable Hardware
The NX-series Controllers provide the hardware reliability and RAS functions that you expect of a
PLC.
Software Features
l
Integrated Sequence Control and Motion Control
An NX-series CPU Unit can perform both sequence control and motion control. You can simultane-
ously achieve both sequence control and multi-axes synchronized control. Sequence control, mo-
tion control, and I/O refreshing are all executed in the same control period.
The same control period is also used for the process data communications cycle for EtherCAT. This
enables precise sequence and motion control in a fixed period with very little deviation.
l
Programming Languages Based on the IEC 61131-3 International Standard
The NJ-series Controllers support language specifications that are based on IEC 61131-3. To
these, OMRON has added our own improvements. Motion control instructions that are based on
PLCopen
®
standards and an instruction set (POUs) that follows IEC rules are provided.
l
Programming with Variables to Eliminate Worrying about the Memory Map
You access all data through variables in the same way as for the advanced programming languag-
es that are used on computers. Memory in the CPU Unit is automatically assigned to the variables
that you create so that you do not have to remember the physical addresses.
l
A Wealth of Security Features
The many security features of the NX-series Controllers include operation authority settings and re-
striction of program execution with IDs.
