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.

About NE1A-series Safety Network Controllers Section 1-1

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.

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.

1-2-1 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.

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 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.

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 Configuration Section 1-2

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.

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.

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.

Safety controls can be monitored by accessing devices on the DeviceNet Safety network using the UDP service from a general-purpose controller on the Ethernet network (e.g., a PLC or computer).

• 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

Switching Hub Connection Methods

• 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.

• 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.

Node Address Setting

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

Software Setting

Method Two-digit decimal

number

Range 0 to 63

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

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.

Initial Setting Section 4-1

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:

Pin Baud rate

OFF ON or

OFF

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

IMPORTANT

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.

• 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.

Setting Description

Enabled (Normal Mode) DeviceNet communications enabled. Disabled (Standalone Mode) DeviceNet communications disabled. The SNC will

operate as a Standalone Controller. “nd” will be displayed on the 7-segment display.

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).
