About NE0A-series Safety Network Controllers Section 1-1

1-1 About NE0A-series Safety Network Controllers

1-1-1 Introduction to the NE0A-series Safety Network Controllers

NE0A-series Safety Network Controllers are programmable safety logic controllers. They are designed for small-scale safety control and provide functions such as safety logic operations, safety local I/O control functions, and DeviceNet Safety Slave communications.

An NE0A-series Controller allows the user to construct safety control circuits that meet the requirements for Safety Integrity Level 3 (SIL 3) according to IEC 61508 (Functional Safety of Electrical/Electronic/Programmable Electronic Safety-related Systems) and the requirements for Safety Category 4 of EN 954-1.

As shown in the following example system configuration, a safety distributed control system can be constructed with an NE0A-series Controller for each safety control block. With this system, the following operations are enabled.

• As Safety Logic Controllers, the NE0A-series Controllers execute safety logic operations and directly control local safety outputs.

• As DeviceNet Safety Slaves, the NE0A-series Controllers perform safety I/O communications with the NE1A-series DeviceNet Safety Master.

• As a DeviceNet Standard Slave, the NE0A-series Controller communicates with the DeviceNet Standard Master.

Constructing Safety Distributed Control Systems for Facilities

Distributing Safety Control with DeviceNet Safety

Shorter Safety Response Times

USB Communications

Force-set/reset

Safety control blocks, such as for individual pieces of equipment, can be connected with less wiring by using DeviceNet cables. Using DeviceNet Safety communications enables transferring interlock signals and other safety data between blocks, and achieves centralized monitoring with DeviceNet standard communications.

Safety response times can be shortened because local safety outputs can be directly controlled without using the Safety Master.

The Network Configurator can be directly connected using USB cable.

Remote I/O signals from a Safety Master can be force-set or force-reset without the Safety Master present, enabling debugging NE0A-series Controllers individually.

Application Templates

Reducing Design Work with Certified Safety Circuits

Using the preinstalled application templates greatly reduces work for constructing circuits that comply with safety standards.

Safety Logic Operations

Constructing Safety Circuits with Software

Safety circuits can be programmed with a wizard to handle various applications, such as emergency stops, door switches with lock functions, and teaching modes. The safety circuits that are created can be easily debugged by using a graphical software tool.

• The terminal block is structured to prevent incorrect insertion.

• For safety inputs, external wiring errors, such as faulty connected devices, wiring mistakes, disconnected wires, short-circuiting, and ground faults, can be detected.

• Using safety outputs in combination with the safety logic EDM function enables detecting errors such as contact weld faults in output devices such as safety relays and contactors.

• Detected errors are shown using the I/O indicators on the front of the NE0A-series Controller, making it easy to identify their location. In addition, the cause of an error can be identified using the Network Configurator.

ductor output devices such as light curtains, can be connected.

• ON and OFF input delays can be set.

• In compliance with Category 4, two related inputs can be set as dual channels.

About NE0A-series Safety Network Controllers Section 1-1

Safety Outputs • ON and OFF output delays can be set.

• In compliance with Category 4, two related outputs can be set as dual channels.

DeviceNet Safety and DeviceNet Standard Communications

Simple Settings Only the node address needs to be set using a rotary switch. The baud rate is

recognized automatically, so it does not need to be set.

DeviceNet Safety Communications

DeviceNet Standard Communications

• A maximum of two connections for safety I/O communications can be set for Safety I/O Slaves.

• Safety I/O communications can be used to exchange safety interlock signals such as emergency stop signals with the NE1A-series Safety Master.

• A maximum of two connections for standard I/O communications can be set for Standard Slaves.

• Standard I/O communications and explicit message communications can be used to monitor NE0A-series Controller status and error information from a standard PLC, enabling errors that occur at the Controller to be immediately identified by standard controls at the PLC.

Access Control with Passwords

Configuration Lock The configuration downloaded to the NE0A-series Controller can be locked. A

password is required to clear the lock, so unauthorized changes can be prevented.

Restrictions on User Operations

A password must be entered to perform operations such as changing the operating mode, downloading data, or force-setting/resetting bits, thus preventing unintentional access to the NE0A-series Controllers.

Maintenance Functions

Monitoring I/O Power Supply Voltage

The local I/O power supply is monitored, and an error occurs if the voltage is incorrect.

Monitoring Unit Power-ON Time

Monitoring the Number of Bit Operations

Monitoring Total ON Time The total time that each input or output bit is ON can be calculated (unit: s)

The total time that power is ON for the internal circuit can be calculated and saved in the NE0A-series Controller.

The number of times each input or output bit turns ON can be counted and saved in the NE0A-series Controller.

1-2 System Configuration

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.

System Configuration Section 1-2

Safety Distributed Control System with DeviceNet Safety

In this example, a safety distributed control system is constructed using a Safety Master and NE0A-series Controllers. In this system, the Safety Master controls the entire system while the NE0A-series Safety Slaves control safety for sub-blocks. The Safety Master executes safety I/O communications with with NE0A-series Safety Slaves. This enables exchanging safety data, such as interlock signals, between the NE0A-series Controllers and the Safety Master.

In addition, using standard I/O communications to assign NE0A-series Controller status information (Unit general status and local I/O errors) and logic operation results to a standard PLC enables central monitoring of the safety control system by the standard PLC.

Note • The NE0A-series Controller uses two Safety Master connection

resources (IN and OUT). For example, up to 16 NE0A-series Controllers can communicate with one NE1A-SCPU01-V1 Controller, which supports a total of 32 connections.

• A maximum total of 64 standard nodes and safety nodes can be connected on the same network.

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.

Centralized Monitoring System with DeviceNet

If safety control blocks requiring a small number of I/O points must be distributed, a safety control system can be constructed using only NE0A-series Controllers without a Safety Master. In this case, the NE0A-series Controllers operate only as DeviceNet Standard Slaves, and do not handle safety I/O communications.

System Configuration Section 1-2

When small-scale safety control blocks are distributed, monitoring with less wiring is enabled from a centralized monitoring system through the DeviceNet network. Error locations and probably causes of errors can be easily identified by using standard I/O communications and explicit messages to assign NE0A-series Controller status information and logic operation results to the standard PLC.

2-3 Local Safety I/O Functions

2-3-1 Local I/O Comments

An optional name of up to 32 characters can be registered in the NE0A-series Controller for each I/O terminal, using the Network Configurator. I/O comments are registered in the safety logic settings of the NE0A-series Controller and in the NE1A-series Logic Editor as I/O tag names, enabling easy conceptualization of what is actually being controlled and simplifying programming.

Note For details on making settings using the Network Configurator, refer to 6-3-3

Setting Local I/O Terminals (Safety Wizard).

2-3-2 I/O Power Monitor

The I/O power supply input can be monitored to confirm if it is normal. If an I/O terminal on the NE0A-series Controller is set to any setting other than Not Used and the normal power supply voltage is not input, an error will be detected and can be confirmed using the following:

• The IN PWR and OUT PWR indicators on the front of the Unit will turn OFF.

• The error will be registered in the error history and can be monitored using the Network Configurator.

• The error will be shown in the Unit general status and can be monitored using an NE1A-series Standard PLC.

Discrepancy Time Evaluation (Monitoring Logic Discrepancies between Two Inputs)

For two inputs set in Dual Channel Mode, the time is monitored from a change in the value of one input to a change in the value of the other input (called the discrepancy time). When the value of the other input does not change within the set discrepancy time, it is treated as an error. The discrepancy time can be set in increments of 10 ms between 0 (disabled) and 65,530 ms. In the Safety Wizard, it is set to 500 ms. The discrepancy time cannot be set in Single Channel Mode.

2-3-4 Local Safety Output Functions

Overview

The safety outputs of the NE0A-series Controller can be flexibly set to handle various applications by selecting the setup and wiring to match the type of external device to be connected and the safety level to be achieved.

The safety outputs of the NE0A-series Controller can detect output signal line errors, such as the following.

• Contact with the power supply line (positive side, only when the output is OFF)

• Ground faults

If the test pulse is enabled, the following errors can be detected.

• Contact with the power supply line (positive side, when the output is ON or OFF)

• Ground faults

• Short-circuits between output lines

Local Safety I/O Functions Section 2-3

Initialization Time The NE0A-series Controller performs initialization when the power supply is

turned ON. During initialization, the NE0A-series Controller performs hardware self-diagnosis. The initialization takes up to 5 s to be completed from the time that the power is turned ON.

DeviceNet Network Online Connection Time

Once the NE0A-series Controller has completed initialization, it will connect to the DeviceNet network after the following operations have been executed:

• Automatic baud rate detection

• Node address duplication check

When the online connection has been established, the NS indicator will light or flash green.

The time required to connect to the network depends on the system configuration.

The NE0A-series Controller matches the baud rate to the network baud rate, so it cannot detect the baud rate and connect to the network if there are no frames being sent over the network. The time required for the NE0A-series Controller to connect to the network will therefore depend on the system configuration, as shown in the following examples, so calculate the time according to the system being used.

When the NE0A-series is set for automatic operation (i.e., Automatic Execution Mode), operation (RUN) will start within 5 s after the power is turned ON. To confirm from an NE1A-series Controller or standard PLC whether NE0Aseries Controller operation has started normally, monitor the RUN Status Flag and the Normal Status Flag in the General Status, in the Remote Input Byte Area, or by using an additional output.

5-2-1 General Instructions on Wiring

Precaution:

• Use separate power supplies for the internal circuit power supply and the I/O power supply.

• Do not connect the internal circuit power supply to a relay or other control component.

• Do not use a cable that is longer than 3 m for the internal circuit power supply.

• To prevent wire clippings from getting into the NE0A-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.

Label prevents wire clippings from entering.

• Disconnect the NE0A-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 NE0A-series Controller.

• Do not apply power to the output terminals. Doing so will cause damage to or burning of the product. In addition, if an attempt is made to start the Unit while power is being applied to the output terminals, a fatal error will occur, the MS indicator will light red, and the Unit will not start correctly.

Note • For details on setting the node address switch and wiring the DeviceNet

communications connector and USB cable, refer to 2-1 Nomenclature.

• For details on I/O wiring, refer to Appendix A Application Templates.

Wiring Section 5-2

5-2-2 Wiring the Power Supply and I/O Lines

Wire Sizes

Use the following wires to connect external I/O devices to the NE0A-series Controller.

Solid wire Stranded (flexible) wire

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 NE0A-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.

0.2 to 2.5 mm

0.34 to 1.5 mm Stranded wires should be prepared by attaching ferrules with plastic

insulation collars (DIN 46228-4 standard compatible) before connecting them.

(AWG 24 to AWG 12)

(AWG 22 to AWG 16)

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.

What Is a Virtual Network?

Creating a Virtual Network

Setting the Network Numbers

The Network Configurator is used to create a network on the personal computer that is identical to the actual network. The network on the computer is called a virtual network.

Create a virtual network using the DeviceNet_1 Network Tree, which appears when the Network Configurator is started. A new DeviceNet_1 Network Tree can be created by selecting File - New - DeviceNet from the Menu Bar.

Select

File - New DeviceNet.

Hardware List

First, set the network numbers.

DeviceNet_1

What Is a Network Number?

Multiple networks can be constructed in a DeviceNet Safety System, and each of the networks is given a unique network number. The network number is combined with the node address to give each device a unique identification number.

■ TUNID (Target Unique Node Identifier)

The value that combines the network number with the node address is called the TUNID and is used to uniquely identify each device. When the Configurator performs actions such as downloading the configuration, it checks whether the TUNIDs match to prevent access to different devices.

Note For details on remote I/O data and the data that can be set, refer to 6-5

Remote I/O Allocations.

Setting the Default Connection Path for Standard I/O Assembly Data

The default connection path must be changed when communicating with a Standard Master that cannot change I/O assembly data. This kind of Standard Master can perform standard I/O communications with a Standard Slave using the default I/O assembly data only. Therefore, the default standard I/O assembly data must be changed.

CS/CJ-series DeviceNet Unit

The I/O assembly data can be changed for a CS/CJ-series DeviceNet Unit, so there is no need to change this setting. Even if this function is used to change the data, the CS/CJ-series DeviceNet Unit settings will be given priority.

Using a Standard Master That Cannot Change Default Standard I/O Assembly Data

Select the I/O assembly data to be allocated in the Standard Master.

IMPORTANT Either safety I/O communications or standard I/O communications, but not

both, can be used for remote output data for the NE0A-series Controller. While safety I/O communications are being used with an NE1A-series Safety Master, standard I/O communications cannot be used with the Standard Master. Route the communications through the Safety Master.

6-3-5 Overview of Safety Logic Settings (Safety Logic Wizard)

Finally, set the safety logic. Safety logic control can be easily performed by setting a combination of I/O data from local I/O terminals and remote I/O data from a Standard Master or Safety Master with the logic operations supported by the NE0A-series Controller.

Configuring NE0A-series Controllers Section 6-3

In addition, the safety status can be monitored from standard controls by using the safety output terminals as additional outputs and outputting data such as error information.

NE0A-series Controller Logic Operations

As shown in the following figure, when RUN mode is entered, local safety inputs are processed in order from safety input evaluations to input condition operation to reset operation, and the result is reflected in the jump address.

Local safety outputs are processed in order from jump address value to output condition operation to welding checks (EDM operation) to safety output evaluation, and the operation result is reflected.

Data received from Safety Master or Standard Master

Safety Input Logic Parameter Setting Operations

Operation for Safety Output Logic Parameter Settings

• Safety Input Evaluation (“Input” in the Above Figure) Input circuit diagnosis, dual channel (discrepancy time) evaluation, and in-

put ON/OFF delays are performed. External wiring errors can be detected.

• Input Condition Operation An OR or AND is taken of the safety input evaluation results.

• Reset Operation Reset operation can be performed for the input condition operation results. This function is used to prevent safety outputs from being automatically

turned ON when an emergency stop is cleared (OFF to ON).

• Output Condition Operation An AND is taken of the safety input logic results. This function is used to

construct safety circuits (safety controls) to turn safety outputs ON and OFF when multiple safety input devices are combined.

• Welding Check (EDM: External Device Monitoring) Operation EDM operation can be performed for output condition operation results. This function is used to detect contact weld faults and external wiring er-

rors in safety output devices such as safety relays and contactors.

• Safety Output Evaluation (“Output: in the Above Figure) Output ON/OFF delays, dual channel evaluation, and output circuit diagno-

sis are performed on EDM operation results. This function can be used to detect external wiring errors.

Configuring NE0A-series Controllers Section 6-3

NE0A-series Controller Additional Outputs

Safety output terminals can be set as additional outputs for the NE0A-series Controller. Error information can be output, along with same and inverse values for other local I/O terminals can be output. These outputs are used for monitor applications and lock clear signal outputs for safety door switches with lock mechanisms.

Note For details on additional outputs, refer to 6-4-6 Safety Output Evaluation.

First set the local I/O terminals and remote I/O data using the procedures shown in 6-3-3 Setting Local I/O Terminals (Safety Wizard) and 6-3-4 Set- ting Networks.

Local I/O Terminal Settings

Remote I/O Terminal Settings

These settings are used only for remote outputs.

Configuring NE0A-series Controllers Section 6-3

2. Set the input logic and the output logic.

Input Logic

Set the safety input logic. In this example, the safety input device is not disabled, so there is no need to set the input condition.

The next example shows an application in which an emergency stop switch is manually reset and a safety door switch is automatically reset.

Output Logic

Set the safety output logic. In this example, the output is turned OFF by pressing an emergency stop switch or by opening a safety door. An interlock signal is also received from the Safety Master to turn OFF the output. In other words, an AND operation will be used between the emergency stop switch, safety door switch, and remote I/O interlock signal.

Icons will be displayed for the devices selected in the local I/O settings.

The welding check feedback input is automatically set for the terminal set in the local I/O settings.

Set the AND condition to control the output.

Set the emergency stop switch to manual reset. The reset switch is connected to IN10, so select "IN10 Low-High-Low."

The safety door switch is auto reset, so this setting is not required.

Select the remote output data.

I/O comments for input logic operation results can be edited. The default is for the same comment as for the local input.

This is the jump address. It is the input for the output condition operation.

Configuring NE0A-series Controllers Section 6-3

IMPORTANT

• The default status for the reset condition is for an auto reset. The setting must be changed to use a manual reset.

• The default status for the output conditions is for an AND operation for all conditions. Change the setting according to the application.

Note For details on individual blocks, refer to 6-4 Descriptions of Logic Commands.

6-3-6 Checking the Settings

Check the settings for the NE0A-series Controller that have been made so far, and then click the Finish Button.

The settings for communications and remote I/O data for the system configuration is displayed first.

Local I/O settings are displayed. Then the logic settings are displayed.

6-4 Descriptions of Logic Commands

This section describes the individual blocks for NE0A-series safety settings.

6-4-1 Safety Input Evaluation

From here on the safety logic setting blocks will be described individually. This description is of the safety

input evaluation. The safety input evaluation logic performs input device

and input circuit diagnosis (using test pulses to diagnose internal circuits and external devices and wiring), dual channel (discrepancy time) evaluation, and input ON/ OFF delays. External wiring errors can be detected.

Note • For details on input device and input circuit diagnosis, input ON/OFF

delays, and dual channel evaluation, refer to 2-3 Local Safety I/O Func- tions.

• The leftmost two local input terminals are used only for reset switches and welding check (EDM) feedback signal inputs.

Diagrams and Functions

The local I/O terminal settings made with the Safety Wizard are saved in the safety input evaluation blocks. Icons for the input devices selected by the local I/O terminal settings will be displayed. The operations performed here depend on the input devices.

(Setting Parameter) Reset signal

Input Condition Operation Result

Safety Input Logic Result

ON is output as the safety input logic result if the reset signal is correctly input when the input condition operation result is ON. Using a manual reset can prevent the equipment from automatically restarting when the NE0A-series Controller power is turned ON, or when the operating mode is changed (from IDLE to RUN), or when a signal from a safety input device changes from OFF to ON.

■ Low-High-Low

Safety input logic operation result ON conditions:

• Input condition operation result is ON.

• In addition, the reset signal goes Low-High-Low.

■ Rising Edge

Safety input logic result ON conditions:

• Input condition operation result is ON.

• In addition, the reset signal goes from Low to High.

IMPORTANT

• The result of the safety input logic operation will turn ON when an auto reset is specified if the power supply of the NE0A-series Controller is started, the operating mode is changed from IDLE to RUN, or the signal from the safety input device goes from OFF to ON.

• If the rising edge is set, noise or other momentary pulse signals will trigger a reset, and the result of the safety input logic operations will turn ON. Therefore, setting Low-High-Low is recommended.
