1-1 About NE1A-series Safety Network Controllers

1-1-1 Introduction to the NE1A-series Safety Network Controllers

The NE1A-series Safety Network Controllers provide various functions, such
as safety logic operations, safety I/O control, and a DeviceNet Safety protocol.
The NE1A-series Controller allows the user to construct a safety control/net­work system that meets the requirements for Safety Integrity Level (SIL) 3
according to IEC 61508 (Functional Safety of Electrical/Electronic/ Program­mable Electronic Safety-related Systems) and the requirements for Safety
Category 4 according to EN 954-1.

In the example system shown below, the safety control system implemented
with an NE1A-series Controller and the monitoring system implemented with
a Standard PLC are realized on the same network.

• As a Safety Logic Controller, the NE1A-series Controller executes safety
logic operations and controls local I/O.

• As a DeviceNet Safety Master, the NE1A-series Controller controls the
remote I/O of DeviceNet Safety Slaves.

• As a DeviceNet Standard Slave, the NE1A-series Controller communi­cates with the DeviceNet Standard Master.

1-1-2 Features of the NE1A-series Controllers

Safety Logic Operations

In addition to basic logic functions, such as AND and OR, function blocks such
as Emergency Stop or Safety Gate Monitoring that enable various safety
applications are supported.

Local Safety I/O

• In the NE1A-SCPU01(-V1)(-EIP), a total of 24 local safety I/O points are
supported: 16 inputs and 8 outputs.

• In the NE1A-SCPU02(-EIP), a total of 48 local safety I/O points are sup­ported: 40 inputs and 8 outputs.

• Faults in external wiring can be detected.

• Dual Channel Mode can be set for pairs of related local input terminals.
When Dual Channel Mode is set, an NE1A-series Controller can evaluate
the input data patterns and the time discrepancy between input signals.

• Dual Channel Mode can be set for pairs of related local output terminals.
When Dual Channel Mode is set, an NE1A-series Controller can evaluate
the output data patterns.

DeviceNet Safety Communications

• As a Safety Master, Pre-Ver. 1.0 Controllers can perform safety I/O com­munications with up to 16 connections using up to 16 bytes per connec­tion.

• As a Safety Master, an NE1A-series Controller with unit version 1.0 or
later (including Controllers that support EtherNet/IP) can perform safety
I/O communications with up to 32 connections using up to 16 bytes per
connection.

• As a Safety Slave, the NE1A-series Controllers can perform safety I/O
communications with a maximum of four connections using up to 16 bytes
per connection.

DeviceNet Standard Communications

As a Standard Slave, the NE1A-series Controllers can perform standard I/O
communications with one Standard Master for up to two connections using up
to 16 bytes per connection.

EtherNet/IP Standard Communications (Only Controllers that Support EtherNet/IP)

As an EtherNet/IP target, an NE1A-series Controller can perform standard I/O
communications with up to two connections with a single EtherNet/IP origina­tor, using up to 128 bytes for input and 16 bytes for output per connection.

DeviceNet Communications Disable (Standalone) Setting

An NE1A-series Controller can be used as a Standalone Controller by dis­abling its DeviceNet communications.

Configuration with a Graphical Tool

• A graphical tool is provided for both network configuration and user pro­gramming. It enables easy configuration and programming.

• A Logic Editor can be activated from the Network Configurator.

• Configuration data can be downloaded and uploaded, and devices can be
monitored online via DeviceNet, USB, EtherNet/IP, or the peripheral inter­face of an OMRON PLC.

4

About NE1A-series Safety Network Controllers Section 1-1

System Startup and Error Recovery Support

• The error information can be checked by using the Network Configurator
or the indicators on the front of the NE1A-series Controller.

• The NE1A-series Controller’s internal status information can be moni­tored from a Standard PLC by allocating the information in the Standard
Master. In the same way, monitoring with a Safety PLC is possible by allo­cating information in the Safety Master.

• An NE1A-series Controller's internal status information can be allocated
in an EtherNet/IP originator and monitored by a Standard PLC. (Possible
only for Controllers that support EtherNet/IP.)

Access Control with a Password

• The NE1A-series Controller’s configuration data is protected by a pass­word set in the Controller.

• The Network Configurator controls access to each project file with a pass­word.

1-1-3 Functional Overview

1-2-1 DeviceNet Safety System Overview

DeviceNet is an open-field, multi-vendor, multi-bit network, which combines
the controls in the machine and line control levels with information. The
DeviceNet Safety network adds safety functions to the conventional
DeviceNet standard communications protocol. The DeviceNet Safety concept
has been approved by a third-party organization (TÜV Rhineland).

Just as with DeviceNet, DeviceNet Safety-compliant devices from third-party
vendors can be connected to a DeviceNet Safety network. Also, DeviceNet­compliant devices and DeviceNet Safety-compliant devices can be combined
and connected on the same network.

By combining DeviceNet Safety-compliant products, a user can construct a
safety control/network system that meets the requirements for Safety Integrity
Level (SIL) 3 according to IEC 61508 (Functional Safety of Electrical/Elec­tronic/Programmable Electronic Safety-related Systems) and the require­ments for Safety Category 4 according to EN 954-1.

1-2-2 Example System Configurations

The following examples illustrate safety control systems using NE1A-series
Controllers.

• Safety Control System with an NE1A-series Safety Master

• System Combining an NE1A-series Safety Control System and a Stan­dard PLC Monitoring Control System

• System Combining a Distributed Safety Control System with Multiple
NE1A-series Controllers and a Centralized Monitoring System Using

• Connection with a Network Configurator

Safety Control System with an NE1A-series Safety Master

This system uses the NE1A-series Controller as a Safety Master and estab­lishes a Safety Remote I/O System with Safety Slaves.

The Pre-Ver. 1.0 Controllers can perform safety I/O communications as a
Safety Master for a maximum of 16 connections (16 Slaves) with up to 16
bytes per connection.

Controllers with unit version 1.0 or later (including Controllers that support
EtherNet/IP) can perform safety I/O communications as a Safety Master for a
maximum of 32 connections (32 Slaves) with up to 16 bytes per connection.

The NE1A-series Controllers support two protocols, single cast and multicast
(broadcast), for safety I/O connections.

System Configuration Section 1-2

System Combining a Safety Control System and a PLC Monitoring Control System

This system uses the NE1A-series Controller as a Safety Master and estab­lishes a Safety Remote I/O System with Safety Slaves.

The NE1A-series Controller is used as a Standard Slave and standard I/O
communications are performed with the Standard Master. The NE1A-series
Controller simultaneously functions as the Safety Master and a Standard
Slave.

As a Standard Slave, the NE1A-series Controller enables standard I/O com­munications for a maximum of two connections with up to 16 bytes per con­nection. Four protocols (i.e., Poll, Bitstrobe, COS and Cyclic) are supported
for I/O connections. The NE1A-series Controller cannot operate as a Stan­dard Master.

The Safety Control System can be monitored using a Standard PLC by allo­cating the NE1A-series Controller’s status information (general status, local
I/O error status, or other information) or logic operation results in the Standard
PLC for standard I/O communications.

A Safety System and a Monitoring System can be combined and established
on the same network by using standard devices and safety devices.

IMPORTANT The data attributes handled by standard I/O communications and explicit

message communications are non-safety data. The necessary measures for
safety data are not taken for this data during data generation. Therefore, do
not use this data to configure the Safety Control System.
A maximum total of 64 standard nodes and safety nodes can be connected on
the same DeviceNet network.

System Combining a Distributed Safety Control System with Multiple NE1A-series
Controllers and a Centralized Monitoring System

This system uses each NE1A-series Controller as a Safety Master and estab­lishes a Safety Remote I/O System with Safety Slaves.

Each NE1A-series Controller also simultaneously functions as a Standard
Slave and standard I/O communications are performed with the Standard
Master.

The Safety Control System can be monitored using a Standard PLC by allo­cating the NE1A-series Controller’s status information (general status, local
I/O error status, or other information) or logic operation results in the Standard
PLC.

In the DeviceNet Safety System, multiple Safety Masters can be connected
on the same network. Therefore, the distributed safety control blocks can be
monitored centrally on the same network.

Also, safety I/O communications between NE1A-series Controllers can be
performed as illustrated in the following diagram. In the diagram, NE1A #2 is
set as the slave of NE1A #1 safety connections to perform safety I/O commu­nications.

The NE1A-series Controller functions as a Safety Master, Safety Slave, and
Standard Slave simultaneously. As a Safety Slave, the NE1A-series Controller
enables safety I/O communications for a maximum of four connections with up
to 16 bytes per connection.

IMPORTANT The data attributes handled by DeviceNet standard I/O communications and

explicit message communications are non-safety data. The necessary mea­sures for safety data are not taken for this data during data generation. There­fore, do not use this data to configure the Safety Control System.

Monitoring DeviceNet or DeviceNet Safety Systems via Ethernet from Controller Made
by Other Manufacturers

If the networks are constructed using an NE1A-EDR01 EtherNet/IP­DeviceNet Router, devices on DeviceNet or DeviceNet Safety network can be
accessed from general-purpose controllers (e.g., PLCs or computers) in an
Ethernet network using the UDP service. This enables monitoring a
DeviceNet or DeviceNet Safety control system via Ethernet from a machine
controller or monitor computer that does not support a DeviceNet interface.
This can be used to easily add a DeviceNet Safety control system to an exist­ing system.

Note Refer to the EtherNet/IP-DeviceNet Router Operation Manual (Cat. No. Z912)

for details on the NE1A-EDR01 EtherNet/IP-DeviceNet Router.

Monitoring a DeviceNet Safety (or DeviceNet) System from a PLC or Controller on an
EtherNet/IP Network

As shown in the following diagram, a DeviceNet Safety (or DeviceNet) system
can be monitored using EtherNet/IP Standard Target I/O from a PLC or Con­troller on an EtherNet/IP network via an NE1A-series Controller that supports
EtherNet/IP.

NE1A-series Controller DeviceNet Communications Disable (Standalone) Setting

When only a few I/O points are required for safety control, the NE1A-series
Controller's DeviceNet communications can be disabled so that it can be used
as a Standalone Controller.

Use the Network Configurator to disable the DeviceNet communications
(standalone).

IMPORTANT Use a USB port connection to disable the DeviceNet communications (stan-

dalone). With Controllers that support EtherNet/IP, either the USB port or Eth­erNet/IP can be used. DeviceNet communications are stopped after
DeviceNet communications are disabled (standalone), so the setting cannot
be made from the DeviceNet port.

2-1-3 Switch Settings

Node Address Switches

Set the DeviceNet node address using the rotary switches on the front of the
NE1A-series Controller.

Note The node address is set to 63 at the factory.

Any node address in the setting range can be used as long as the same
address is not used by another node. If a value between 64 and 99 is set on
the rotary switches, the node address can be set using a software setting on
the Network Configurator.

IMPORTANT

• Turn OFF power to the NE1A-series Controller before setting the rotary
switches.

• Do not change the rotary switches while the power is ON. The Controller
will detect this as a change in the configuration and will switch to ABORT
State.

• A node address duplication error will occur if the same address is set for
more than one node. Communications will not start if this error occurs.

Note

• Use a small flat-blade screwdriver to set the rotary switches, being careful
not to scratch them.

• Refer to 4-1 Initial Setting for software setting procedures.

Baud Rate Switch

The DeviceNet baud rate is set using the DIP switch on the front of the NE1A­series Controller. The baud rate settings are shown in the following table:

Note The baud rate is set to 125 kbit/s at the factory.

3-2-1 General Instructions on Wiring

Precaution:

• To prevent wire clippings from getting into the NE1A-series Controller, do
not remove the label on the Controller before wiring has been completed.

• After wiring has been completed, be sure to remove the label from the
Controller to enable heat dissipation for proper cooling.

• Disconnect the NE1A-series Controller from the power supply before
starting any wiring operations. Devices connected to the Controller may
operate unexpectedly if wiring is performed with the power supply con­nected.

• Be careful not to get your fingers caught when attaching connectors to the
plugs on the NE1A-series Controller.

Label prevents wire
clippings from entering.

!WARNING

Serious injury may possibly occur due to loss of required safety functions. Wire the con­ductors correctly and verify the operation of the NE1A-series Controller before using the
Controller system in actual operation.

Wiring Section 3-2

3-2-2 Wiring the Power Supply and I/O Lines

Wire Sizes

Use the following wires to connect external I/O devices to the NE1A-series
Controller.

Recommended Materials and Tools

■ Insulated Pin Terminals

Use a pin terminal with an insulated cover compliant with the DIN 46228-4
standard. Pin terminals similar in appearance but not compliant with the stan­dard may not match the terminal block on the NE1A-series Controller. (The
wiring dimensions are rough standards. Confirm the dimensions beforehand.)
Use wires of the same diameter if two-wire pin terminals are used.

Note • When wiring with pin terminals, be sure to insert pin terminals all the way

into the terminal block.

• When using two-wire pin terminals, use wires of the same diameter.

• When using two-wire pin terminals, insert the pin terminal so that metal

portion of the pin terminal is inserted straight into the terminal block, i.e.,
so that the long sides of the insulating cover are vertical.

IMPORTANT

• Be sure to separate I/O cables from high-voltage/current lines.

• Use I/O cables of 30 m or less.

• Do not apply the power supply to the test output terminals. Doing so may
result in product damage or burning.

!WARNING

Serious injury may possibly occur due to breakdown of outputs. Do not connect loads
beyond the rated value to the safety outputs and the test outputs.

Serious injury may possibly occur due to loss of required safety functions. Wire the
NE1A-series Controller properly so that 24-VDC lines do NOT touch the safety outputs
and the test outputs accidentally or unintentionally.

Serious injury may possibly occur due to loss of required safety functions. Ground the 0­V line of the power supply for external output devices so that the devices do NOT turn
ON when the safety output line or the test output line is grounded.

Serious injury may possibly occur due to loss of required safety functions. Use appropri­ate components or devices according to the requirements given in the following table.

3-2-4 DeviceNet Wiring

Wire the DeviceNet communications cable as shown in the following diagram.

Stickers are placed on the communication connectors based on the color of
each communications wire. By matching the communications wire colors with
the connector sticker colors, you can check to see if wires are in the correct
locations. The colors of the wires are as follows:

• Turn OFF the power supply to the NE1A-series Controller, to all nodes on
the network, and to communications lines before starting any wiring oper­ations.

• Tighten the DeviceNet connector to the appropriate torque (0.25 to

0.3 N·m).

• Separate the DeviceNet communications cables from high-voltage/current
lines.

Note Refer to the DeviceNet Operation Manual (W267) for further information on

wiring.

3-2-6 Ethernet (EtherNet/IP) Network Installation

Basic Installation
Precautions

• Take the greatest care when installing the Ethernet System, being sure to
follow ISO 8802-3 specifications. You must obtain a copy of these specifi­cations and be sure you understand them before attempting to install an
Ethernet System.

• Unless you are already experienced in installing communications sys­tems, we strongly recommend that you employ a professional to install
your system.

• Do not install Ethernet equipment near sources of noise. If a noisy envi­ronment is unavoidable, take adequate measures against noise interfer­ence, such as installing network components in grounded metal cases or
using optical cable in the system.

Recommended
Network Devices

The following table shows the devices recommended for use with the NE1A­series Controller.

Note • Ask the switching hub manufacturer for setting procedures for the switch-

ing hub.

• Install the switching hub so that its environmental resistance capabilities
are not exceeded.
Ask the switching hub manufacturer for information on the environmental
resistance of the switch hub.

Precautions

Precautions on Laying
Twisted-pair Cable

• Noise resistance may be reduced by ground loops, which can occur due
to improper shield connections and grounding. Ground the shield at one
location, as shown in the following diagram.

• Do not connect a shield at the NE1A-series Controller connector.

• If a cable connects two hubs, connect the shields at only one end.

Wiring Section 3-2

• Press the cable connector in firmly until it locks into place at both the
switching hub and the NE1A-series Controller.

• Do not lay the twisted-pair cable together with high-voltage lines.

• Do not lay the twisted-pair cable near devices that generate noise.

• Do not lay the twisted-pair cable in locations subject to high temperatures
or high humidity.

• Do not lay the twisted-pair cable in locations subject to excessive dirt and
dust or to oil mist or other contaminants.

Switching Hub Installation
Environment Precautions

• Do not ground the switching hub in the same location as a drive-system
component such as an inverter.

• Always use a dedicated power supply for the switching hub’s power sup­ply. Do not use the same power supply used for other equipment, such as
an I/O power supply, motor power supply, or control power supply.

• Before installation, check the switching hub’s environment-resistance
specifications, and use a switching hub appropriate for the ambient condi­tions. Contact the switching hub manufacturer for details on switching
hub’s environment-resistance specifications.

Switching Hub
Connection Methods

• Connect two hubs to each other as follows: Connect an MDI port to an
MDI-X port with a straight cable; connect two MDI ports with a cross
cable; and connect two MDI-X ports with a cross cable.

Note It is very difficult to distinguish cross cables and straight cables by

appearance. Incorrect cables will cause communications to fail. We
recommend using cascade connections with straight cables when­ever possible.

• Some switching hubs can automatically distinguish between MDI and
MDI-X. When this kind of switching hub is being used, straight cable can
be used between switching hubs.

Wiring Section 3-2

Note NE1A-series Controller link settings must match the communications mode

settings of connected switching hubs. If they do not match, links will be unsta­ble and normal communications will not be possible. For EtherNet/IP I/O com­munications (tag data link communications) with an EtherNet/IP standard
originator, it is recommended that auto-negotiation or 100M full-duplex com­munications be set for the Controller and the switching hubs.

Ethernet Connectors The following standards and specifications apply to the connectors for the

Ethernet twisted-pair cable.

• Electrical specifications: Conforming to IEEE802.3 standards.

• Connector structure: RJ45 8-pin Modular Connector

(conforming to ISO 8877)

Note The NE1A-series Controller Ethernet ports support the auto-MDI/MDI-X func-

tionality, so either a straight or cross cable can be used.

Connecting the Cable

!Caution Turn OFF the power to the NE1A-series Controller before connecting or dis-

connecting twisted-pair cable.

4-1-1 Hardware Setup

Node Address Setting

Set the DeviceNet node address using the rotary switches on the front of the
NE1A-series Controller.

Note The node address is set to 63 at the factory.

Any node address in the setting range can be used as long as the same
address is not used by another node. If a value between 64 and 99 is set on
the rotary switches, the node address can be set using a software setting on
the Network Configurator.

Software Setting

Use the following procedure to set the node address using the Network Con­figurator.

1. Turn OFF the power and then set the rotary switches to a number between
64 and 99 (software setting).

2. Turn ON the power. The NE1A-series Controller will operate using the pre­vious node address (factory set to 63).

3. Reset to the default settings using the Network Configurator’s RESET
command.
The configuration information held in the device will be initialized.

4. Set the node address from the Network Configurator.

From here on, the NE1A-series Controller will operate with the node address
set in the software setting.

IMPORTANT

• Turn OFF power to the NE1A-series Controller before setting the node
addresses.

• Do not change the rotary switches while the power is ON. The NE1A­series Controller will detect this as a change in the configuration and will
switch to Abort State.

• A node address duplication error will occur if the same address is set for
more than one node. Communications will not start if this error occurs.

Note Use a small flat-blade screwdriver to set the rotary switches, being careful not

to scratch them.

Baud Rate Setting

The DeviceNet baud rate is set using the DIP switch on the front of the NE1A­series Controller. The baud rates settings are shown in the following table:

Note The baud rate is set to 125 kbit/s at the factory.

Software Setting

The Network Configurator can be used to set the baud rate. The procedure is
as follows:

1. Turn OFF the power and change the DIP switch to the “software setting.”

2. Turn ON the power. When power is turned ON, the NE1A-series Controller
will operate at the previous baud rate (default setting: 125 kbit/s).

3. Reset to the default settings using the Network Configurator’s RESET
command.
The configuration information held in the device will be initialized.

4. Set the baud rate from the Network Configurator.

5. Reset the NE1A-series Controller by cycling the power or using the NE1A­series Controller RESET command from the Network Configurator. The
NE1A-series Controller will then operate with the baud rate set from the
Network Configurator, i.e., the software setting.

Automatic Baud Rate Detection

The NE1A-series Controller’s baud rate can be set automatically to match the
baud rate of the master on the network. The baud rate must be set in at least
one Safety Master or Standard Master on the network. After turning ON the
power, the baud rate is set when establishing communications, and the baud
rate setting is stored until the next time power is turned ON.

IMPORTANT

• Turn OFF power to the NE1A-series Controller before setting the DIP
switch.

• Do not change the DIP switch setting while the power supply is ON. The
NE1A-series Controller will detect this as a change in the configuration
and will switch to ABORT State.

• The baud rate must be the same for all nodes (masters and slaves) on the
network.

Disabling DeviceNet Communications (Standalone)

When DeviceNet Communications are disabled, the NE1A-series Controller
stops all DeviceNet communications and operates as a Standalone Control­ler. The default is to have DeviceNet communications enabled (normal mode).

Make the setting from the Network Configurator. After the setting has been
made, a reset command will be sent from the Network Configurator to the
NE1A-series Controller to enable the setting.

IMPORTANT

• When DeviceNet communications are disabled, connect the NE1A-series
Controller to the Network Configurator via a USB connection or via Ether­Net/IP (for Controllers that support EtherNet/IP).

• When DeviceNet communications are disabled, operation using the Net­work Configurator can be performed via a USB connection or via Ether­Net/IP (for Controllers that support EtherNet/IP).
