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.
l Providing Database Connection Service
The database connection service is a function to insert, update, retrieve, and delete records to/from
a relational database on a server connected to the built-in EtherNet/IP port or EtherNet/IP Unit (X
Bus Unit) by executing special instructions on the NX502 CPU Unit.
In addition, secure communications can be established by using the encrypted communication
function.
No special Unit and tool are required for the database connection function. You can use the NX502
CPU Units and Sysmac Studio.
Also, the server does not need any special middleware for connection to the NX-series CPU Units.
For details on the database connection service, refer to the NJ/NX-series Database Connection
CPU Units User's Manual (Cat. No. W527).
Note An SD Memory Card is not included.
l Complete Controller Monitoring
The CPU Unit monitors events in all parts of the Controller, including mounted NX Units and Ether-
CAT slaves.
Troubleshooting information for errors is displayed on the Sysmac Studio or on an NS-series PT.
Events are also recorded in logs.
l Sysmac Studio Automation Software
The Sysmac Studio provides an integrated development environment that covers not only the Con-
troller, but also covers peripheral devices and devices on EtherCAT. You can use consistent proce-
dures for all devices regardless of the differences in the devices. The Sysmac Studio supports all
phases of Controller application, from designing through debugging, simulations, commissioning,
and changes during operation.
l A Wealth of Simulation Features
The many simulation features include execution, debugging, and task execution time estimates on
a virtual controller.
