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)
Page 19
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.

Instance specification: An instance of an instruction is indicated by “XX_instance” above a FB instruction. You must assign an instance name to any instance of an instruction that you specify.
The input variable or output variable is given.
•Name The name of the variable is given. Example: Up-counter
• I/O Whether the variable is an input variable or output variable is given.
• Description The meaning of the variable and any restrictions are given.
• Valid range The range that the variable can take is given. “Depends on data type” indicates that the valid range of the variable depends on the data type that you use. The valid ranges of the data types are given later in this section.
•Default The specified default value is automatically used for the variable if you do not assign a parameter to the instruction before it is executed. “---” indicates the following: Input variables: The default value of the data type of the input variable is assigned. The default values of the data types are given later in this section. Output variables: Default values are not set.
• Data type The data type of the variable is given. Broadly speaking, there are two classifications of data types: safety signals and non-safety signals. These two classifications of data types are described later.

Item Description
Function The function of the instruction is described. Additional Informa-
tion Precautions for Cor­rect Use
Additional information on the function of the instruction is provided. This includes related instructions and helpful information for application of the instruction. Precautions for application of the instruction are given. The conditions under which errors occur for the instruction are also given here.

1-2-2 Safety Data Types and Standard Data Types

The Safety Control Unit classifies the following two data types to distinguish between safety signals and standard signals.
• Safety data types: These data types represent signals related to safety control.
• Standard data types: These data types represent signals related to standard control.
The safety data type variables are prefixed with the “SAFE” before the name of the standard data type, as in SAFEBOOL and SAFEBYTE.
You can input a signal for a safety data type variable to a standard data type variable. You cannot input a signal for a standard data type variable to a safety data type variable. A building error will occur.

1-2-3 Valid Ranges and Default Values of Variables

The valid range of a variable indicates the range of values that variable can take. The default value of a variable indicates the value that is assigned to an input variable when the instruction is executed with­out a parameter assigned to the input variable. These values are defined for each data type. If specific values are not given for an instruction, then the valid ranges and default values of the data types are applied. These variables are indicated by “depends on data type” in the valid range column of the table that describes the variables and by “---” in the input variable default column. The valid ranges and default values of the data types are given in the following tables.

1-2-4 Timer Set Values
Time set values, such as those for DiscrepancyTime or the OFF-Delay Timer instruction, operate in increments of the safety task period.
The timer error is +1 safety task period. Every safety task period, a timer value is checked to see if it has reached the set time. If the timer value reaches the set time immediately after this check, the time is delayed by one safety task period.
Examples are provided below.

When the OFF-Delay Timer Instruction Is Set to 500 ms and the Safety Task
Period Is Set to 16 ms
The timer will time out 512 ms (16 ms × 32) after the safety task is started.
When the OFF-Delay Timer Instruction Is Set to 500 ms and the Safety Task
Period Is Set to 20 ms
The timer will time out 520 ms (20 ms × 26) after the safety task is started. Care is required because the timer will not operate at 500 ms.
Refer to the NX-series Safety Control Unit User’s Manual (Cat. No. Z930) for details on the safety task period.
The time when an OFF-Delay Timer instruction times out can affect the safety reaction times.

JUMP and LABEL

This function moves processing to the jump destination specified by a label.
Instruction Name FB/FUN Graphic expression
JUMP Jump FUN
LABEL Label FUN
Variables
There are no variables for these instructions.
Function
When the execution condition is TRUE, the JUMP instruction moves processing to the jump destination specified by a label in the program. The label can be any text string.
The following figure shows a programming example. This example uses the text string Step1 as the label. When the JUMP instruction is executed, processing moves to the location marked Step1. In this exam­ple, programming C between the JUMP instruction and the label is not executed. The outputs in pro­gramming C retain the values that they had just before the JUMP instruction was executed.

Additional Information
• You cannot jump upward in the networks.
• You can use the same label as the jump destination for more than one JUMP instruction.
• You can set only a label in a network, or you can set both programming and a label in a network.
Precautions for Correct Use
• You must use either a BOOL or SAFEBOOL execution condition for the JUMP instruction. If you connect an execution condition with any other data type, a building error will occur.
• You cannot omit labels. If you omit a label, a building error will occur.
• Place the JUMP instruction and label in the same POU.
• Programming between the JUMP instruction and the label is not executed when the JUMP instruction is executed. The outputs retain the values that they had just before the JUMP instruction was exe­cuted.

Function
RETURN
When the execution condition is TRUE, control is returned to the location that called the POU without executing any processing after RETURN.
The following figure shows a programming example. When the RETURN instruction is executed in the example, programming C and D that follow it are not executed. The outputs in programming C and D retain the values that they had just before the RETURN instruction was executed.
Precautions for Correct Use
• You must use either a BOOL or SAFEBOOL execution condition for the RETURN instruction. If you connect an execution condition with any other data type, a building error will occur.
• If you use this instruction too often, the flow of processing will be difficult to understand. Use it with caution.
• Programming after the RETURN instruction is not executed when the RETURN instruction is exe­cuted. The outputs retain the values that they had just before the RETURN instruction was executed.

• You must use Boolean variables for In1 to InN and for Out.
• The input condition depends on whether the output is safety data or standard data. If the condition is not met, a building error will occur.
Setting a Safety Data Type Variable for the Output Terminal
AND: Set a safety data type variable for at least one of the input terminals.
OR/XOR: Set safety data type variables for all of the input terminals.
Setting a Standard Data Type Variable for the Output Terminal
AND/OR/XOR: Use either safety data type variable or standard data type variable for the input ter­minals.

DWORD data.
*1. For example, if the value of In1 is INT#32767 and the value of In2 is INT#3, the addition result will be 32770.
If an INT variable is set for the output, the value of the addition result will be the value that can be expressed with lower 16 bits of the sum (32,770), i.e., −32,766. If a DINT variable is set for the output, the addition result is DINT#32770.
*2. If the result exceeds the valid range of DINT data, the result will be the value that can be expressed with the
lower 32 bits.
*3. For example, if the value of In1 is TIME#49d17h2m47s295ms and the value of In2 is TIME#5ms, the value of
the addition result is TIME#49d17h2m47s30ms. However, the maximum value of TIME is the same as for DWORD (4294967295), so the addition result will be the value that can be expressed with 32 bits, i.e., TIME#4ms.

Precautions for Correct Use
• The data types of In1 to InN and Out can be different. If they are different, calculations are performed with the data type that includes the range of all of the data types. For example, if In0 is INT data and In1 is DINT data, calculations are performed with DINT data. Therefore, addition result Out will be DINT data.
• The input condition depends on whether the output is safety data or standard data. If the condition is not met, a building error will occur.
• If you set a safety data type variable for the output terminal, set safety data type variables for all of the input terminals.

Precautions for Correct Use
• The data types of In1, In2, and Out can be different. If they are different, calculations are performed with the data type that includes the range of all of the data types. For example, if In0 is INT data and In1 is DINT data, calculations are performed with DINT data. Therefore, subtraction result Out will be DINT data.
• The input condition depends on whether the output is safety data or standard data. If the condition is not met, a building error will occur.
• If you set a safety data type variable for the output terminal, set a safety data type variable for the two input terminals as well.
• If you set a standard data type variable for the output terminal, you can set either a safety data type variable or a standard data type variable for the input terminal.

Additional Information
You cannot include more than one duration in the values to multiply. To multiply a duration, set a duration for In1 and Out and set integers for In2 to InN.
Precautions for Correct Use
• When multiplying integers, the data types of In1 to InN and Out can be different. If they are different, calculations are performed with the data type that includes the range of all of the data types. For example, if In1 is INT data and In2 is DINT data, calculations are performed with DINT data. There­fore, multiplication result Out will be DINT data.
• If you use duration data for the data to multiply, use duration data for one of In1 to InN and for Out.
• The input condition depends on whether the output is safety data or standard data. If the condition is not met, a building error will occur. If you set a safety data type variable for the output terminal, set safety data type variables for all of the input terminals.
• If you set a standard data type variable for the output terminal, you can set either a safety data type variable or a standard data type variable for the input terminal.
• If you set a safety data type variable for the output terminal, set safety data type variables for all of the input terminals.
• If you set a standard data type variable for the output terminal, you can set either a safety data type variable or a standard data type variable for the input terminal.
