Safety Precautions
Fail-safe Measures
Provide safety measures in external circuits to ensure safety in the system if an abnormality
occurs due to malfunction of the CPU Unit, Industrial PCs, other Units, or slaves or due to
other external factors affecting operation.
Not doing so may result in serious accidents due to incorrect operation.
Emergency stop circuits, interlock circuits, limit circuits, and similar safety measures must
be provided in external control circuits.
The CPU Unit or Industrial PCs will turn OFF all outputs from Output Units in the following
cases. The remote I/O slaves will operate according to the settings in the slaves.

• If the power supply connection becomes faulty.
• If a CPU watchdog timer error or CPU reset occurs.

The outputs may remain ON or OFF due to deposition or burning of the output relays or
destruction of the output transistors. As a countermeasure for such problems, external
safety measures must be provided to ensure safe operation of the system.
If external power supplies for slaves or other de

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.*1
Whether the products conform to the standards in th
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.

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 NX-series Units comply with EU Directives. To ensure that the machine or device in which the
NX-series Units are used complies with EU Directives, the following precautions must be observed.
• The NX-series Units must be installed within
• The SELV requirements must be satisfied for the DC
Unit power supplies and I/O power supplies for the NX-series Units.
EMC standard compliance was confirmed for the recommended Power Supplies. Refer to the

configuration of the control panel used, other devices connected to the control panel, wiring, and

1-1Features of Communications Inter-
face Units
The NX-series Communications Interface Units (hereafter called CIF Units) provide the following features.
Features as Sysmac Devices
The CIF Units are classified as Sysmac devices. Sysmac device is a generic name for EtherCAT
slaves, EtherNet/IP slaves, and other OMRON control components that were designed with the
same communications and user interface specifications. You can use Sysmac devices together with
NJNX-series Machine Automation Controllers and the Support Software to achieve optimum functionality and ease of operation.
Features as NX Units
The CIF Units are classified as NX Units.
NX Units are connected to an NX-series CPU Unit or NX-series Communications
use them.
Coupler Unit to
Multiple NX Units can be flexibly combined
cation with less wiring, less work, and less space.

Features as Serial Communications Devices
The CIF Units are also classified as serial communications devices. Both RS-232C and
RS-422A/485 are supported as the serial interface. No-protocol communications are supported as
the communications protocol.

Other convenient functions include logging send/rece

Preventing Incorrect Attachment of Terminal Blocks
In order to prevent unintentionally installing the wrong terminal block, you can limit the combination of a
Unit and a terminal block.
Insert three Coding Pins (NX-AUX02)
into three of the six incorrect attachment prevention holes on the
Unit and on the terminal block. Insert these pins into positions so that they do not interfere with each
other when the Unit and terminal block are connected to each other.
You can use these pins to create a combination in which the wrong terminal block cannot be attached

To make the maximum of 20 patterns, purchase two sets of NX-AUX02 Pins. (One set for 10 Units.)
• OMRON uses the holes other than No. 1 to 6 in the figure on the previous page. If you insert
a Coding Pin into one of the holes used by OMRON on the terminal block side, this makes it
impossible to mount the terminal block on a Unit.
• Do not use Coding Pins that have been attached and removed.
Inserting the Coding Pins
1Hold the pins by the runner and insert a pin into one of the incorrect attachment prevention
holes on the terminal block or on the Unit.
2Rotate the runner to break off the Coding Pins.

4-4-3Examples of Recommended RS-232C and RS-422A/485 Wiring
This section provides examples of the recommended RS-232C and RS-422A/485 wiring.
Examples of Recommended RS-232C Wiring
We recommend the following wiring for RS-232C communications, particularly in environments where
noise is
common.
• Use shielded, twisted-pair cable for the communications cable.
• Pair the SD (send data) line with the SG (signal ground)
line as one twisted pair and the RD (receive
data) line with the SG (signal ground) line as a separate twisted pair.
• For the NX-CIF210, connect the shield on the communications cable to the shell (SHLD) on the
D-Sub con
nector on the NX-CIF210. Also, ground the ground terminal (GR) on the Power Supply
Unit to 100 or less.
• For the NX-CIF101, connect the shield on the communic
ations cable to A6 (SHLD) on the
NX-CIF101. Also, ground the A8 (FG) on the NX-CIF101 to 100 or less.

Examples of Recommended RS-422A/485 Wiring
For RS-422A/485, we recommended that you use the follow
quality.
• Use shielded, twisted-pair cable for the communications cable.
• Connect the shield on the communications cable to A8 or
the A8 or B8 (FG) on the NX-CIF101 to 100 or less.

• Always turn ON the terminating resistance at the
turn ON the terminating resistance, connect TERSDA- and TERSDB+ for a two-wire connection and
connect TERRDA- and TERRDB+ for a four-wire connection.
Ground the shield only at the CIF Unit. Do not ground it at the other end of the cable. If you
ground both ends of the cable, a difference in electrical potential between the two grounds may
damage the equipment.

-3 for the items to set and the setting ranges.
6-1-2Transmission Buffering
The send data from the CPU Unit or communications master to a CIF Unit may sometimes be divided
into pieces and sent over multiple cycles. With transmission buffering, CIF Unit first stores the divided
send data in a send buffer inside the CIF Unit. When all of the send data has been received, the CIF
Unit sends all of it at the same time on the serial line.
When transmission buffering is not used, each piece of the send data sent separately from the CPU
Unit or communications master to the CIF Unit is immediately sent to the serial line. Therefore, in this
case, the data sent from the CIF Unit to the serial line may also be divided into pieces.
You can enable or disable transmission buffering with a setting on the Support Software.

Detecting the Final Data When Transmission Buffering Is Enabled
When transmission buffering is enabled, the CPU Unit or communications master must tell the CIF Unit
when all of the send data is stored in the send buffer. The Output Data Type in the output notification
data that is sent from the CPU Unit or communications master to the CIF Unit is used for this purpose.
The meanings of bits 12 to 15 in the Output Data Type are given in the following table.
