In this manual, “download” refers to transferring data from the Sysmac Studio to the physical Controller
and “upload” refers to transferring data from the physical Controller to the Sysmac Studio.
For the Sysmac Studio, synchronization is used to both upload and download data. Here, “synchronize”
means to automatically compare the data for the Sysmac Studio on the computer with the data in the
physical Controller and transfer the data in the direction that is specified by the user.

Regulations and Standards
NJ/NX-series Troubleshooting Manual (W503)
Regulations and Standards
• EMC Directives
• Low Voltage Directive
EMC Directive
OMRON devices that comply with EU Directives also conform to the related EMC standards so that
they can be more easily built into other devices or the overall machine. The actual products have
been checked for conformity to EMC standards.*
Whether the products conform to the standards in the system used by the customer, however, must
be checked by the customer. EMC-related performance of the OMRON devices that comply with EU
Directives will vary depending on the configuration, wiring, and other conditions of the equipment or
control panel on which the OMRON devices are installed. The customer must, therefore, perform
the final check to confirm that devices and the overall machine conform to EMC standards.
* Applicable EMC (Electromagnetic Compatibility) standards are as follows:
EMS (Electromagnetic Susceptibility): EN 61131-2
EMI (Electromagnetic Interference): EN 61131-2 (Radiated emission: 10-m regulations)
Low Voltage Directive
Always ensure that devices operating at voltages of 50 to 1,000 VAC and 75 to 1,500 VDC meet the
required safety standards. The applicable directive is EN 61010-2-201.
Conformance to EU Directives
The NJ/NX-series Controllers comply with EU Directives. To ensure that the machine or device in
which the NJ/NX-series Controller is used complies with EU Directives, the Controller must be
installed as follows:
• The NJ/NX-series Controller must be installed within a control panel.
• You must use the power supply in SELV specifications for the DC power supplies connected to
DC Power Supply Units and I/O Units.
• NJ/NX-series Controllers that comply with EU Directives also conform to the Common Emission
Standard (EN 61000-6-4). Radiated emission characteristics (10-m regulations) may vary
depending on the configuration of the control panel used, other devices connected to the control
panel, wiring, and other conditions.
You must therefore confirm that the overall machine or equipment complies with EU Directives.

Observe the following precaution if you use NX-series Units in Korea.
Class A Device (Broadcasting Communications Device for Office Use)
This device obtained EMC registration for office use (Class A), and it is intended to be used in places
other than homes.
Sellers and/or users need to take note of this.
The NJ/NX-series Controllers comply with the following shipbuilding standards. Applicability to the
shipbuilding standards is based on certain usage conditions. It may not be possible to use the prod-
uct in some locations. Contact your OMRON representative before attempting to use a Controller on
a ship.
• The NJ/NX-series Controller must be installed within a control panel.
• Gaps in the door to the control panel must be completely filled or covered with gaskets or other
material.
• The following noise filter must be connected to the power supply line.

Versions
NJ/NX-series Troubleshooting Manual (W503)
Versions
Hardware revisions and unit versions are used to manage the hardware and software in NJ/NX-series
Units and EtherCAT slaves. The hardware revision or unit version is updated each time there is a
change in hardware or software specifications. Even when two Units or EtherCAT slaves have the
same model number, they will have functional or performance differences if they have different hard-
ware revisions or unit versions.
You can check versions on the ID information indications or with the Sysmac Studio.
The unit version is given on the ID information indication on the side of the product.
The ID information on an NX-series NX701- CPU Unit is shown below.
Note The hardware revision is not displayed for the Unit that the hardware revision is in blank.

Note The hardware revision is not displayed for the Unit that the hardware revision is in blank.
You can use the Sysmac Studio to check unit versions. The procedure is different for Units and for Eth-
erCAT slaves.
Checking the Unit Version of an NX-series CPU Unit
You can use the Production Information while the Sysmac Studio is online to check the unit version
of a Unit. You can do this for the CPU Unit. For an NX1P2 CPU Unit, you can also check the unit
versions of the NX Units on the CPU Rack and Option Boards.
1Right-click CPU Rack under Configurations and Setup −CPU/Expansion Racks in the
Multiview Explorer and select Production Information.
The Production Information Dialog Box is displayed.
Checking the Unit Version of an NJ-series CPU Unit
You can use the Production Information while the Sysmac Studio is online to check the unit version
of a Unit. You can do this for the CPU Unit, CJ-series Special I/O Units, and CJ-series CPU Bus
Units. You cannot check the unit versions of CJ-series Basic I/O Units with the Sysmac Studio.
Use the following procedure to check the unit version.
1Double-click CPU/Expansion Racks under Configurations and Setup in the Multiview
Explorer. Or, right-click CPU/Expansion Racks under Configurations and Setup and select
Edit from the menu.
The Unit Editor is displayed.
