OR
The OR instruction takes the logical OR of the value of a specified BOOL variable and the execution
condition and outputs it to the next instruction. Use the OR instruction for a NO bit connected in parallel
with the previous instruction. Use the OR instruction to configure a logical OR between an NO bit and
one of the following : a LD or LDN instruction connected directly to the bus bar, or the logic block starting
with a LD or LDN instruction and ending with the instruction immediately before the OR instruction.
ORN
The ORN instruction takes the logical OR of the inverse of the value of a specified BOOL variable and
the execution condition and outputs it to the next instruction. Use the ORN instruction for a NC bit connected in parallel with the previous instruction. Use the ORN instruction to configure a logical OR
between an NC bit and one of the following: a LD or LDN instruction connected directly to the bus bar,
or the logic block starting with a LD or LDN instruction and ending with the instruction immediately
before the ORN instruction.
The following figure shows a programming example of the OR instruction. It takes the logical OR of variable A and variable B and outputs it to variable C.
OR: Takes the logical OR of the value of a BOOL variable and the execution condition.
ORN: Takes the logical OR of the inverse of the value of a BOOL variable and the execution condi-
tion.

Conformance to EC Directives
Applicable Directives
• EMC Directive
• Machinery Directive
Concepts
EMC Directives
OMRON devices that comply with EC 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 the system used by the customer, however, must
be checked by the customer. EMC-related performance of the OMRON devices that comply with EC
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.
16
*1. 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).
Machinery Directive
The Machinery Directive demands that the safety components that are used to provide safety for the
relevant machinery are used according to the required levels of safety.
The applicable directives are EN ISO 13849-1:2008 and EN 62061 SIL CL3.
NX-series Safety Control Unit Instructions Reference Manual (Z931)
Regulations and Standards
Conformance to EC Directives
The NX-series Units comply with EC Directives. To ensure that the machine or device in which the
NX-series Units are used complies with EC Directives, the following precautions must be observed.
• The NX-series Units must be installed within a metallic control cabinet.
• You must meet the following conditions for the DC power supplies that are connected as the Unit
power supplies and I/O power supplies for the NX-series Units.
(a) Use reinforced insulation or double insulation.
(b) Ensure an output hold time of 20 ms min.
(c) Use an SELV power supply that meets the requirements of IEC/EN 60950-1 and EN
50178.
Do not allow the power supply cable length to exceed 3 m.
We recommend that you use the OMRON S8JX-series Power Supplies. EMC standard compliance was confirmed for the recommended Power Supplies.
• NX-series Units that comply with EC Directives also conform to the Common Emission Standard
(EN 61131-2). 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 in which the NX-series Units
are used complies with EC Directives.
• This is a Class A product (for industrial environments). In a residential environment, it may cause
radio interference. If radio interference occurs, the user may be required to take appropriate measures.
Conformance to EN ISO 13849-1 and EN 62061
International standards EN ISO 13849-1 and EN 62061 demand that process controls be in place for
the creation of safety-related software when building a safety control system that uses Safety Control
Units. The process control must ensure that the software is easy to read, understand, test, and maintain
to avoid system failures during each phase (i.e., general software design, safety circuit system design,
and software upgrades) of the software design lifecycle.
This means that process controls must also be in place for the design and development of safety software, such as for equipment and machinery that use function blocks that are provided by the Safety
Control Units.
It is the customer’s responsibility to conform with all standards.
Conformance to UL and CSA Standards
The NX-series Safety Control Units comply with the following UL and CSA standards. The application
conditions for standard compliance are defined. Refer to the Instruction Sheet that is provided with
each Unit before application.

1-1 Types of Instructions
The following three types of instructions can be used with the Safety Control Units.
Type Description
Standard functions These function instructions do not use safety data. They include program
execution control instructions, data type conversion instructions, Boolean
operation instructions, math instructions, comparison instructions, etc.
Safety standard function blocks These function block instructions use safety data. They include counter
instructions, up/down trigger instructions, timer instructions, etc.
Safety function blocks These function block instructions use safety data and are based on the safety
standards defined by PLCopen. They include an antivalent instruction, emergency stop instruction, etc.
Instruction specifications are provided starting from section 2.
Some of the instructions have the same names as the instructions that are supported by the
NJ-series CPU Units. Operating specifications, however, are different.
