NX-series Safety Control Units
NX-SL/SI/SO
Integration of Safety into Machine
Automation Enables Simple,
Flexible System Configuration.
• EN ISO13849-1 (PLe/Safety Category4), IEC 61508 (SIL3) certified.
• One connection using Safety over EtherCAT (FSoE) * protocol
enables flexible configuration by mixing the Safety Units with
standard NX I/O.
• Hardware and safety circuits can be configured using the Sysmac
Studio (Ver. 1.07)
* Safety over EtherCAT (FSoE): The open protocol Safety over EtherCAT (abbreviated with FSoE "FailSafe over EtherCAT") defines a safety
related communication layer for EtherCAT. Safety over EtherCAT meets the requirements of IEC 61508 SIL 3 and enables the transfer of safe
and standard information on the same communication system without limitations with regard to transfer speed and cycle time.
Features
•Integrated safety into machine automation possible by connecting with the NX-series EtherCAT Coupler.
•The Safety CPU Unit controls up to 128 Safety I/O Units.
•4 or 8 points per Safety Input Unit. The 4-point Safety Input Unit can be directly connected with OMRON Non-contact Switches and Singlebeam
Sensors.
•2 or 4 points per Safety Output Unit. The 2-point Safety Output Unit is characterized by large output breaking current of 2.0 A.
•The Safety Units can be freely allocated in any combination with standard NX I/O.
•Compliant with IEC61131-3
•Safety programs can be standardized and reused efficiently by using POUs for design and operation.

Exposed Variable Settings You set whether to expose global variables of the Safety CPU Unit. The values of exposed variables
can be referenced from NJ/NX-series CPU Units and NY-series Industrial PCs.
Standard Process Data
Communications *2
You set the devices and ports of the Standard I/O Units for the exposed variables of the Safety CPU
Unit.
Safety Task Settings You define the execution cycle and timing of the safety task and programs to be executed in the task.

Instruction List (Toolbox)
A hierarchy of the functions and function blocks that you can use is displayed in the Toolbox. You
can drag the required functions and function blocks onto the FBD editor to insert it to a safety
program.
FBD Programming You connect variables, functions, and function blocks with connecting lines to build networks. The
FBD editor is used to enter them.
Adding FBD Networks You create FBD networks on the FBD editor to create algorithms.
Inserting and Deleting
Functions and Function blocks
You insert and delete functions and function blocks on the FBD editor.
Entry Assistance When you enter functions, function blocks, or parameters, each character that you enter from the
keyboard narrows the list of candidates that is displayed for selection.
Commenting Out FBD
Networks
You can comment out each FBD network. When a network is commented out, it is no longer
executed.
Converting Programs into
Function Blocks *1You can convert the safety program into user-defined function block.
Automatic Programming *1A safety programs can be automatically generated from input and output signals and expected
values of the program.
Creating Variables You create variables used in safety programs in the global or local variable table.
User-defined Function Blocks You create user-defined function blocks.

Debugging
Monitoring
Variables are monitored during safety program execution. You can monitor the present values of
device variables assigned to Safety I/O Units and user-defined variables. The values can be
monitored on the FBD editor or Watch Tab Page.
Changing the Present Values of Variables You can change the present values of user-defined variables and device variables as required. You
can do this on the FBD editor or Watch Tab Page.
Forced Refreshing
The inputs from external devices and outputs to external devices are refreshed with a specified value
on the Sysmac Studio. The specified value is retained even if the value of the variable is overwritten
from the user program.
You can use forced refreshing on the FBD editor or Watch Tab Page.
Offline Debugging *5You can check if the control program logic works as designed in advance using a special debugging
function for the Simulator without connecting online with the Safety CPU Unit.
Initial Value Settings *6You can set the initial values of variables when you start execution of simulation.
Feedback Settings *6You can set input status that is linked to changes in output status when simulator is running.
Simple Automatic Test *7You can check that expected values of the outputs to the inputs of the program are designed as
intended using the Simulator functions of the Safety CPU Unit.
User Memory Usage Monitor *6The memory usage of the safety control system and usage of safety network such as I/O data size
are displayed.
Debugging Online Functional Test *1
This function helps you to check the safety functional operation of the safety system.
You can produce output device operation relative to the input and check whether the system
operates as expected. It is possible to output the check results.
Safety
Safety Validation You append the "safety-validated" information to a safety program when you can ensure safety of
the program after you complete debugging.
Changing Operating Mode There are four operating modes; PROGRAM mode, DEBUG mode (STOPPED), DEBUG mode
(RUN), and RUN mode. The RUN mode can be selected only for the validated safety programs.
Maintenance
Generating Safety Data Logging Settings
File *1Settings to use the safety data logging function can be generated as a file.
Generating Safety Unit Restore File *1A file of safety program and settings to be transferred to the Safety CPU Unit using an SD memory
card is generated for Safety Unit Restore function.

Applicable Terminal Blocks for Each Unit Model
Applicable Wires
Using Ferrules
If you use ferrules, attach the twisted wires to them.
Observe the application instructions for your ferrules for the wire stripping length when attaching ferrules.
Always use plated one-pin ferrules. Do not use unplated ferrules or two-pin ferrules.
The applicable ferrules, wires, and crimping tool are given in the following table.
*Some AWG 14 wires exceed 2.0 mm2 and cannot be used in the screwless clamping terminal block.
When you use any ferrules other than those in the above table, crimp them to the twisted wires so that the following processed dimensions are
achieved.

Using Twisted Wires/Solid Wires
If you use the twisted wires or the solid wires, use the following table to determine the correct wire specifications.
*1 Secure wires to the screwless clamping terminal block. Refer to the Securing Wires in the USER'S MANUAL for how to secure wires.
*2 With the NX-TB@@@1 Terminal Block, use twisted wires to connect the ground terminal. Do not use a solid wire.
<Additional Information> If more than 2 A will flow on the wires, use plated wires or use ferrules.
