Unit Versions of NE1A-series Controllers

Checking the Unit Version

A “unit version” has been introduced to manage NE1A-series Safety Network Controllers according to differences in functionality accompanying Unit upgrades, even though the model numbers are the same.

The unit version can be checked on the product itself or using the Network Configurator.

Note The Network Configurator maintains a revision number to manage device

functions for DeviceNet and EtherNet/IP. Refer to “Checking the Unit Version with the Network Configurator” on page xxiv for the relationship between NE1A-series Controller unit versions and the revisions.

Checking the Unit Version on the Product Nameplate

The unit version (Ver. @.@) is listed near the lot number on the nameplate of the products for which unit versions are being managed, as shown below.

• The unit versions of the NE1A-SCPU01, NE1A-SCPU02, NE1A-SCPU01EIP, and NE1A-SCPU02-EIP Controllers begin from Ver. 1.0.

• Controllers that do not have a unit version listed on the label are called Pre-Ver. 1.0 Controllers.

Precautions Updating from Network Configurator Version 1.3@ to a Higher Version

Data Compatibility

Data created using Network Configurator version 1.3@ can be used with a higher version without any problems if converted as outlined below. Data created with higher versions cannot be used with lower versions; the data upload from the device will fail when loading the project file.

Procedure for Converting Data from Version 1.3@ to a Higher Version

Version 1.5@ and higher have improved safety check functions, so version programs from lower versions will need to be checked for safety. Use the following procedure to check programs.

a. Click the Logic Tab on the Edit Device Parameters Window of the

NE1A-series Controller and click the Edit Button to start the Logic Editor.

b. Select Edit - Find Function Blocks with Open Connections to

check that all function block I/O have connections.

c. Select File - Apply to save the logic program then exit the editing of

the logic program.

d. Return to the NE1A-series Controller's Edit Device Parameters Win-

dow and click the OK Button.

Note Data created using version 1.3@ cannot be monitored online.

Always convert the data to version 1.5@ and download it before monitoring online.

Handling Function Blocks with Open I/O Connections

Function block outputs with open connections in version 1.3@ data could still be downloaded (see following diagram).

Download cannot be executed with version 1.5@ or higher, however, if there are outputs with open connections (to improve the program validity).

For this reason, data created using version 1.3@ cannot be downloaded as is for use with version 1.5@ or higher. If open connections exist in version 1.3@ data, use the Search Open Connection function and use the Set Output Point Tab Page in the Safety Gate Monitoring Window for the function block with open connections to disable the outputs or connect the open connections to output I/O tags.

Open connection

Note Versio ns 1.5@ and higher have functions for creating text boxes on program

screens and changing the I/O tag color. The text box and I/O color data is not

xxxi

saved to the NE1A-series Controller, however, during download. For this reason, text box and I/O tag color data is not restored when the program is uploaded.

1-1 DeviceNet Safety System Overview

1-1-1 About DeviceNet Safety

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 standard DeviceNet 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 Safety Network Controller Overview

1-2-1 About the NE1A-series Safety Network Controllers

The NE1A-series Safety Network Controllers provide various functions, such as safety logic operations, safety I/O controls, and a DeviceNet Safety protocol. The NE1A-series Controllers allow 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/ Program- mable 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 the NE1A-series Controller and the monitoring system implemented with the 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 Safety Master, the NE1A-series Controller controls the remote I/O of Safety Slaves.

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

Safety Network Controller Overview Section 1-2

1-2-2 NE1A Series Features

Safety Logic Operations

In addition to basic logic functions, such as AND and OR, the NE1A-series Controllers also support application function blocks, such as Emergency Stop Pushbutton Monitoring and Safety Gate Monitoring, that enable various safety applications.

User-defined Function Blocks

Previously prepared logic functions and function blocks can be combined to create a user-defined function block using the Network Configurator version

1.5@ or higher. This can be used to standardize functions that are used frequently to facilitate reusing them. Passwords can also be used to protect the programming inside the function blocks by making them “black boxes.”

Local Safety I/O

• A total of 24 local safety I/O points are supported by NE1A-SCPU01(V1)(-EIP): 16 input terminals and 8 output terminals.

• A total of 48 local safety I/O points are supported by NE1A-SCPU02(EIP): 40 input terminals and 8 output terminals.

• Faults in external wiring can be detected.

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

DeviceNet Safety Communications

• As a Safety Master, a Pre-Ver. 1.0 NE1A-series Controller can perform safety I/O communications with up to 16 connections using up to 16 bytes per connection.

• As a Safety Master, any NE1A-series Controller other than a Pre-Ver. 1.0 NE1A-series Controller 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 Controller 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 Controller 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 (Controllers that Support EtherNet/IP Only)

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

Disabling DeviceNet Communications (Standalone)

An NE1A-series Controller can be used as a Standalone Controller by using a setting to disable the Controller's DeviceNet communications.

Configuration with a Graphical Tool

• A graphical tool is provided for both network configuration and logic pro-

gramming. It enables easy configuration and programming.

Safety Network Controller Overview Section 1-2

• 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, or EtherNet/IP.

System Startup and Error Recovery Support

• Error information can be checked by using the error history 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, the information can be monitored from a safety PLC by allocating the information in the Safety Master.

• The NE1A-series Controller's internal status information can be monitored from a standard PLC by allocating the information in an EtherNet/IP Originator.

Access Control with a Password

• NE1A-series Controller configuration data is protected by a password.

• Network configuration files (project files) created with the Network Configurator are also password protected.

• Programs and user-defined function blocks can be password-protected using the Network Configurator version 1.5@ or higher.

1-3 Network Configurator Overview

1-3-1 About the Network Configurator

The WS02-CFSC1-E Network Configurator Support Software is used to configure, set, and manage a DeviceNet Safety network with graphical window operations.

The Network Configurator can be used to configure a virtual DeviceNet Safety network (in the Network Configuration Window) and monitor the configuration and parameters of each safety device and standard device.

1-3-2 Network Configurator Features

Compliant with Standard and Safety DeviceNet Networks

The Network Configurator can configure and monitor devices that support DeviceNet Safety or EtherNet/IP as well as existing standard DeviceNet devices. It can thus support building systems for standard control, safety control, or mixed standard/safety control.

Multiple Network Configurations Supported (Version 2.0@ or Later)

Multiple DeviceNet network configurations can be made in one project. Starting with version 2.2@, it is also possible to build multiple EtherNet/IP networks in one project.

Safety Network Controller Programming

The Network Configurator provides built-in programming tools for the safety logic of the NE1A-series Controllers and thus enables building DeviceNet Safety applications using only the Network Configurator.

• Previously prepared function blocks can be incorporated in logic. AND/OR and other logic functions and emergency stop button/safety door/light curtain monitoring, and other previously prepared function blocks can be selected from the function block list and placed in the Workspace to create software connections in the logic of the Network Controller.

Network Configurator Overview Section 1-3

• User-defined function blocks can be easily created and reused using the Network Configurator version 1.5@ or higher.

New user-defined function blocks can be created. These can be used simply by selecting them from the function block list and placing them in the Workspace. Created user-defined function blocks can be saved to file and installed on another computer to use with the Network Configurator on that computer.

• Editing of user-defined function blocks can be password-protected.

Upward Compatibility with DeviceNet Configurator

All the functions of DeviceNet Configurator are supported. Also, all of the files created by the DeviceNet Configurator can be used as they are.

Programming

2. Installation and Wiring

3. Configuration

4. User Test

1-4-1 System Design and Programming

In this step, the optimum safety system is determined by the following procedures:

1. Based on the required safety system specifications, select and arrange the safety devices and determine the safety functions to be allocated to each device.

2. Configure the network system as a virtual network in the Network Configurator.

• Register all of the devices. If the system is a mixed safety control and standard control system, register both the safety devices and standard devices.

• Set the parameters of all the devices.

• Check the percentage of the network bandwidth being used and review the parameters.

• Create the program for the NE1A-series Controller.

• Verify the system reaction time of all the safety chains.

The network bandwidth usage and the system reaction time are affected by several factors, including the network configuration, NE1A-series Controller and Safety I/O Terminal parameter settings, and NE1A-series Controller program, so repeat the steps above to determine a system configuration which meets the users’ requirements.

Please refer to the following sections for the operating instructions of the Network Configurator.

• Device Registration Refer to 3-4 Creating a Virtual Network.

1-4-3 Configuration

In this step, transfer the parameters for each device created by the Network Configurator to the actual device to make the system operative.

Use the Network Configurator to perform the following operations:

1. Download The parameters set in the Network Configurator's virtual network are transferred to the actual device and stored in each device.

2. Verification Verify the safety device settings. The user confirms that the parameters and safety signatures stored in each device are correct.

Please refer to the following sections for the operating instructions of the Network Configurator.

• Download Refer to 3-7 Device Parameters and Properties.

• Verification Refer to 3-8 Parameter Verification.

IMPORTANT • After downloading the device parameters, verify the parameters to con-

firm that the parameters and the safety signature saved in the devices are correct.

• When selecting Open Only in the Open Type setting for the safety connection, check that the Safety Master and Safety Slave are correctly configured.

1-4-4 User Test

Safety functions may be impaired and serious injury may occasionally occur. Before operating the system, perform user testing to confirm that the configuration data of all the devices is correct and that they are operating correctly.

IMPORTANT • After configuring all the devices, user testing must be performed to check

In this step, the user himself confirms the program operation and performs functional tests.

Always perform the user test, because it is the user’s responsibility to verify the system operation. The user test verifies the correctness of all parameters downloaded to each safety device, as well as each device’s safety signature. To demonstrate that all parameters and safety signatures are correct after completing the user test, perform a Configuration Lock operation on all of the safety devices.

Refer to 3-9 Configuration Lock for details on performing a Configuration Lock from the Network Configurator.

!WARNING

Allocating Network Bandwidth Usage and Calculating the Best EPI Section 2-2

2-2 Allocating Network Bandwidth Usage and Calculating the

Best EPI

Almost all of the DeviceNet network bandwidth can be used for safety I/O and standard I/O communications.

Communications may time out, however, if the connection settings exceed the acceptable bandwidth usage for each type of communications.

Check the connection settings and, if a setting is found to exceed the acceptable bandwidth usage rate, the setting must be changed to the value outlined in the following table.

• Safety I/O communications

• Standard I/O communications

The network configuration may need to be changed if the settings exceed the acceptable bandwidth usage rate as a result of securing the required communications performance (i.e., the required network reaction time for safety I/O communications).

This section describes how to check the network bandwidth used for safety I/O communications in the designed network, how to calculate the best EPI from the set bandwidth usage rate, and how to re-set the value.

EPI (Expected Packet Interval) setting for safety connections

Master communications cycle time

2-2-1 Checking the Network Bandwidth Used for Safety I/O

Communications

The actual network bandwidth usage rate for safety I/O communications for the connections set in the virtual network is displayed at the bottom of the Network Configuration Window under Usage of Network Bandwidth for Safety Connections. The network bandwidth usage rate is displayed for each baud rate, as shown in the following diagram.

When a virtual network (including programming) is created, the network bandwidth usage conditions of safety connections at each baud rate are displayed.

As shown in the diagram, the faster the baud rate, the lower the bandwidth usage rate.

IMPORTANT Keep 10% or more of the network bandwidth available for establishing con-

nections and for explicit message communications with the Network Configurator, whether using only safety I/O communications or using both safety I/O and standard I/O communications. Even if 10% or more is available, however, safety or standard communications might time out, depending on the Network Configurator operation (e.g., monitoring or other operations that create a load on the network) or if the user

Allocating Network Bandwidth Usage and Calculating the Best EPI Section 2-2

application uses explicit message communications. If timeouts occur, reduce the network bandwidth usage rate (i.e., increase the unused bandwidth).

Performing Only Safety I/O Communications

When performing only safety I/O communications, there is no problem if the network bandwidth used for safety I/O communications is approximately 90%.

If the bandwidth exceeds 90%, obtain the best average EPI for all connections by referring to 2-2-3 Allocating Network Bandwidth Usage Rates and Calculat- ing Best EPI and change the EPI setting for each connection.

Performing Safety I/O Communications and Standard I/O Communications

When both safety I/O communications and standard I/O communications are used on one network, it is necessary to determine the network bandwidth to use for each type of communications. Problems will occur if only the network bandwidth for safety I/O communications is determined, because some network bandwidth is required for standard I/O communications.

Refer to 2-2-3 Allocating Network Bandwidth Usage Rates and Calculating Best EPI and enter the network bandwidth used for each type of communications and set the best average EPI for each safety connection and the communications cycle time of the Standard Master.

2-2-2 Displaying Device Bandwidth Usage Conditions

The conditions of bandwidth used in the EtherNet/IP network can be displayed. The function applies to all EtherNet/IP devices and can be used if the EtherNet/IP network is displayed.

1. Click the tab for the EtherNet/IP Network Configuration Window.

2. Click the Detail Button. The Usage of Device Bandwidth Dialog Box will be displayed.

Net/IP systems.

2-2-3 Allocating Network Bandwidth Usage Rates and Calculating Best

EPI

The average EPIs for safety I/O communications and standard I/O communications and the best communications cycle time are calculated by entering the network bandwidth usage rate for each type of communications into the Network Configurator.

Calculate the best average EPIs and the best communications cycle using the following procedure. The network configuration might need to be changed if the required communications characteristics cannot be achieved.

1. Make the required settings for the virtual network on the Network Configu-

rator, including creating programs for the Safety Network Controller.

2. Click the Calculate EPI Button at the bottom of the Network Configuration Window. The Calculate EPI Dialog Box will be displayed.

3. Input the network bandwidth used in safety I/O communications and the bandwidth used in standard I/O communications.

• If using only safety I/O communications:

Input the network bandwidth used by the safety connections as 90% or less and input 0% for the network bandwidth used by standard connections.

Allocating Network Bandwidth Usage and Calculating the Best EPI Section 2-2

If using both safety and standard I/O communications: Input the total network bandwidth used for safety and standard connections as 90% or less, e.g., 40% for safety connections and 30% for standard connections. Safety and standard I/O communications will use the bandwidth based on the rates specified here.

4. Click the Calculate Button.

5. The best average EPI of all the connections in the safety I/O communica-

tions and the optimum Master communications cycle time in the standard I/O communications will be displayed for each baud rate.

6. Perform the following trial calculation.

• When using safety I/O communications only Increase the network bandwidth for safety connections to 90%. If the desired best EPI for each safety connection cannot be calculated, try increasing the EPI for connections that need faster speeds (EPI settings, step 9 as described later).

• When using a mixture of safety and standard I/O communications: Try changing the network bandwidth usage rate and calculating the EPI, as described below.

• Increase the usage rate for safety connections to shorten the EPI for safety I/O communications and lengthen the communications cycle time for standard I/O communications.

• Conversely, increase the usage rate for standard communications to

shorten the cycle time for standard I/O communications and increase the EPI for safety I/O communications.

7. Check the Safety Network Controller cycle time. Next, check that the cycle times calculated in the previous steps are longer

than the Safety Network Controller cycle time. If they are shorter, the Safety Network Controller cycle time will be the minimum that can be set for the EPI. The Safety Network Controller cycle time can be checked offline after creating the program, under Cycle Time on the Mode/Cycle Time Tab in the Edit Device Parameters Dialog Box. Refer to 5-6 Setting the Operating Mode and Confirming the Cycle Time.

Allocating Network Bandwidth Usage and Calculating the Best EPI Section 2-2

IMPORTANT The minimum possible EPI setting is larger value of either the Safety Network

Controller cycle time or the Safety Slave cycle time (fixed at 6 ms). The minimum possible EPI will be affected, therefore, if the Safety Network Controller cycle time is longer than 6 ms.

8. Reconsider the network configuration itself if you have performed the test calculation as outlined above and either of the following occur, i.e.,

• the desired best average EPI for each safety connection and the best

communications cycle time for the Standard Master cannot be calculated, or

• the Safety Network Controller cycle time is longer than the best average

EPI.

Consider adjusting the following aspects of the network configuration.

• Reducing the number of nodes or I/O points.

• Splitting the network

• If using both safety and standard I/O communications, split the network into a DeviceNet Safety network and a standard DeviceNet network.

• If using only safety I/O communications, split the network into two DeviceNet Safety networks.

9. Change the EPI settings for each safety connection and the Standard Master communications cycle time setting to suit the desired baud rate.

• Changing the EPI Settings for Each Safety I/O Connection The best average EPI calculated is the best average of all safety connec-

tions. The following method is used for setting the calculated EPI as the EPI in

the parameters for all safety connections.

• Method for batch setting the best EPI to devices

a. Click the Update Device Configuration Button. The Update Device Configuration Dialog Box will be displayed.

b. Select the baud rate to be used and click the OK Button.

The calculated best average EPI value will be batch set as the EPI in the safety connection parameters for all devices.

c. If required, adjust the EPI settings for the whole network, making the

EPI smaller for those connections that need a faster response time (e.g., for safety curtain connections) and making the EPI larger for

Allocating Network Bandwidth Usage and Calculating the Best EPI Section 2-2

those connections that do not need a fast response (e.g., for door switches not used in hazardous areas). Refer to the reaction time listed in the EPI field to check what the reaction time will be for each safety connection EPI setting.

Note Set the EPI for each safety connection longer than Safety Network

Controller cycle time. If the EPI is shorter, errors will occur when the safety connection parameters are downloaded and the download will fail.

• Changing Standard Master Communications Cycle Times The value calculated as the best average cycle time is the best communi-

cations cycle time for the Standard Master. Set the calculated value as the Standard Master communications cycle

time.

10. Reconfirm the bandwidth usage rate. If the EPI settings in the safety connection parameters or the Standard Master communications cycle time setting has been changed based on the calculation results, check that the network bandwidth usage when safety connections are used, displayed at the bottom of the Network Configuration Window, is less than the value input in the Calculate EPI Dialog Box. It is particularly important to check the bandwidth usage rate if the best average EPI has been adjusted for each connection rather than applied as a batch setting.

Note The EPI is set in 1-ms units, so the network bandwidth usage rate

may be smaller than the input value if the calculation result is input directly.

11. Perform a test to ensure that there are no problems with the set values.

Allocating Network Bandwidth Usage and Calculating the Best EPI Section 2-2

2-2-4 Example of EPI Calculations

The following network configuration is used for an example of calculating the EPI.

Conditions

The baud rate is 500 Kbit/s.

■ Safety I/O Communications

Example: The NE1A-series Controller sets safety connections between six DST1-ID12SL-1 Input Terminals and five DST1-MD16SL-1 I/O Terminals. The default set values are used for all the safety connections, and the EPI is 10 ms.

■ Standard I/O Communications

Example: The CJ1W-DRM21 sets the standard connections between six DRT2-ID16 Input Terminals and five DRT2-OD16 Output Terminals. The default set values are used, and the communications cycle of the CJ1WDRM21 is automatically set but it attempts to operate at a cycle time of about

3.2 ms.

Allocating Network Bandwidth Usage and Calculating the Best EPI Section 2-2

Calculations

Here, we allocate 70% network bandwidth usage rate to safety connections and 20% to standard connections.

Click the Calculate Button and from the calculation results, you can see the EPI for the safety connections can be set to 7 ms and the communications cycle of the Standard Master can be set to 6 ms.

Checking the Safety Network Controller Cycle Time

If, for example, the Safety Network Controller cycle time was 6 ms, it is shorter than the calculation result of 7 ms which means the result can be set as the EPI.

Changing Settings

Changing the EPI Settings for Each Safety I/O Connection

Set the EPI of all safety connections set in the NE1A-series Controller to 7 ms according to the calculation results.

Allocating Network Bandwidth Usage and Calculating the Best EPI Section 2-2

Click the Update Device Configuration Button to batch set the calculation result of 7 ms as the EPI for all safety connections by selecting the baud rate to be used.

Refer to 2-2-3 Allocating Network Bandwidth Usage Rates and Calculating Best EPI.

Changing Standard Master Communications Cycle Time Settings

Set the communications cycle of the CJ1W-DRM21 to 6 ms.

Calculating and Verifying the Reaction Time Section 2-3

2-3 Calculating and Verifying the Reaction Time

The last step in designing the network is calculating the reaction time of safety chains. The user must check that the reaction time in all the safety chains meets the requirement specifications.

2-3-1 Concept of Reaction Time

Reaction time is the worst down time among the running devices considering faults and failures in safety chains. The safety distance is calculated from reaction time.

The reaction time is calculated for each safety chain. The typical combinations of safety chains are as follows:

1. Standalone NE1A-series Controller (DeviceNet Communications Disabled)

IMPORTANT In the SNC program, add the time for the NE1A-series Controller cycle time to

the reaction time of the safety chain when the output from a function block is fed back to the input side of the function block.

Check the NE1A-series Controller cycle time, I/O refresh cycle time, and network reaction time in the Network Configurator.

Check the NE1A-series Controller cycle time and I/O refresh time in Mode/ Cycle Time Tab of the Edit Device Parameters Window.

2-3-3 Verifying the Maximum Reaction Time

Check that the calculated maximum reaction time meets the required specifications in all safety chains. If the reaction time exceeds the required specifications, re-examine the network design, taking into consideration the following points for the maximum reaction time to meet the requirement specifications:

• Shortening the EPI will shorten the network reaction time. Shortening the

EPI, however, narrows the network bandwidth that can be used for other connections.

• The NE1A-series Controller cycle time is automatically calculated based

on the program size, the number of connections, etc. It is also possible to use different NE1A-series Controller Controllers for safety chains that require a high-speed reaction time and other safety chains.

In addition, the Display Route Path and Display Connection Details are sup- ported as display options.

Select the Display Route Path option to display a route (EtherNet/IP if registered via the NE1A-EDR01).

If the Display Route Path option is not selected, only the networks on which master devices and slave devices exist will be displayed, and not the route.

If the Display Connection Details option is selected, an asterisk (*) is displayed at the connected master device.

“R” and “F” indicate the number of resources required for communications. “R” indicates the number of communications resources required by each

device. “F” indicates the number of communications required by each device. Users do not normally need to be aware of the these values because they are calculated automatically by the Network Configurator.

3-3-4 Connecting to a Network

This section describes the basic concept of connecting the Network Configurator to an actual network.

As shown in the following figure, the description will use an example with multiple networks in a system. In the example in the figure, the networks are DeviceNet_1, EtherNet_1, and DeviceNet_2.

Connecting to the Network Section 3-3

(1)

DeviceNet_1

NE1A-series Controller

EtherNet_1

(3)

(2)

NE1A-EDR01

DeviceNet_2

There are three ways to connect the Network Configurator to the network.

a. Connection via a USB port (connection to an NE1A-series Controller) b. Connection via a DeviceNet Interface Card c. Connection via Ethernet (NE1A-EDR01: Network Configurator version

2.0@ or higher, NE1A-SCPU01-EIP or NE1A-SCPU02-EIP: Network Configurator version 2.2@ or higher)

With Network Configurator version 1.6@ or earlier, operations (e.g., downloading and uploading) can be performed only for networks that have devices connected. In the figure above, if a connection is made at network 1, only devices on DeviceNet_1 can be accessed, and if connection is made at network 2, only devices on DeviceNet_2 can be accessed.

When using Network Configurator version 2.0@ or higher with a network that contains the NE1A-EDR01, CPU Units with unit version 2.0, and CPU Units that support EtherNet/IP (see note 2), uploading, downloading, and other online operations can be performed for networks other than the network to which the connected device belongs. If a connection is made to the NE1ASCPU01 Controller (pre-version 1.0) in network 1, operations can be performed only for the DeviceNet_1 network.

Note (1) For CPU Units with unit version 1.0 or earlier, uploading and downloading

can be performed only for devices that are connected to the network to which the CPU Unit belongs.

(2) CPU Units (with EtherNet/IP) support the Network Configurator of version

2.2@ or higher.

When the Network Configurator is connected to the network, a blue icon will be displayed on the tab of a destination network, and a green icon will be displayed on the tab of an operable network, as in the following figure.

The tab may remain grey after a network has been set to online. This indicates that the network is inoperable at the present online destination. The connection destination must be changed to operate the network. Change the connection destination using the procedure described in 3-3-5 Changing a Connection Destination.

3-3-5 Changing a Connected Network

This section describes how to change a connection destination.

Note This function is enabled only when connection is made to the NE1A-EDR01

via Ethernet, connection is made to the NE1A-SCPU02 (unit version 2.0) via

Connecting to the Network Section 3-3

USB, or connection is made to the NE1A-SCPU01-EIP or NE1A-SCPU02-EIP via USB or Ethernet.

1. Select Network - Select Connect Network Port. The Select Connect Net- work Port Dialog Box will be displayed.

2. Select the network to be connected, and then click the OK Button. The Select Connected Network Dialog Box will be displayed.

3. Select the network to be connected, and then click the OK Button. If an online connection is made normally, On-line will be displayed in the status bar at the bottom of the window.

A tab for the network to be connected will be displayed in blue as in the following figure.

Note Until Select Connect Network Port is used again to change the con-

nection destination, the network selected in step 3 (displaying a blue icon) and related networks (displaying a green icon) will be operable.

Creating a Virtual Network Section 3-4

3-4 Creating a Virtual Network

To set device parameters and to program NE1A-series Controllers, create a virtual network in the Network Configurator, set the device parameters in the virtual network, and then download the parameters to the actual devices.

This section describes how to create a virtual network.

3-4-1 Creating a New Virtual Network

When the Network Configurator is started, a new virtual network can be created.

Use one of the following methods to create a new virtual network.

1. Select File - New from the menu bar.

2. Click the New Button on the toolbar.

Alternatively, select Network - Add from the menu bar to add another new virtual network.

Note When a new virtual network is created with unit version 1.6@ or higher, the vir-

tual network information that was displayed until then will be deleted. If the previous virtual network information is required, save the data before creating a new virtual network.

3-4-2 Network Numbers

The DeviceNet Safety System can be used to build multiple networks. Network numbers are used in combination with node addresses to specify unique devices and confirm communicating nodes in this kind of multi-network configuration. This value is called a TUNID (Target Unique Network Identifier) and is stored in the non-volatile memory of each device.

Setting TUNIDs

The TUNID is automatically set when parameters are first downloaded from the Network Configurator to a device in out-of-the-box configuration. (See note.)

Note “Out-of-the-box configuration” indicates the status when a reset-type device is

returned to its default status and restarted.

Users do not normally need to be aware of the existence of network numbers because they can visually identify a device on the Network Configurator.

The default network number is automatically generated based on the date and time the Network Configurator created the network configuration, but it can also be specified by the user.

Cases Where the User Needs to Specify Network Numbers

The automatically generated network numbers will be sufficient when the Network Configurator is used to set all the devices on the network. In the following cases, however, the user must set a different network number for each network.

1. When multiple Network Configurators are used to set individual devices: When more than one Network Configurator is used to make settings on the same network, the same network number must be set for each device.

2. When more than one type of setting software is used: When setting software other than Network Configurator is used because devices made by other manufacturers are being used, specify the same network number with each type of setting software.

Creating a Virtual Network Section 3-4

Precautions When Downloading to Existing Networks

The following precautions must be heeded because parameters cannot be downloaded to devices if the new automatically generated TUNID to be transmitted is different from the TUNID in the device memory.

Always use one of the four methods listed below when downloading parameters to a device that has already had parameters downloaded to it.

If the download is executed using a different method, the download will fail because the transmitted TUNID and the TUNID in the device memory are different. A “Different TUNID” error message will appear in the error history.

Method 1: Download the parameters using the previously created net-

work configuration file.

Method 2: Download the parameters based on the configuration

obtained from a network upload.

Method 3: If using a newly created network configuration file, get the

network number from the actual network (a function of Network Configurator version 1.50 or higher; see note). Make the virtual network number in Network Configurator the same as the actual network number and then download the parameters.

Note Use the following procedure to get the network number.

(a) Select Network – Property or right-click the Network Configura-

tion Window and select Property. Click the Get from the actual network Button in the Network Number Area in the Network Property Dialog Box.

(b) The network number of the real number that you want to down-

load will be read to the personal computer.

execute the download.

Method 4: If using a device that has been used in another location, reset

the device to out-of-the-box configuration (see note) and download using methods 1, 2, or 3.

Note Select Device – Reset or click the right mouse button and select

Reset to display the Reset Device Dialog Box. Set the reset type to Return to the out-of-box configuration, and then emulate cycling power and click the OK Button.

Generally, method 1 should be used, i.e., save the master network configuration file and use it to make any network configuration or parameter changes. Then download parameters using that master file.

When connecting a new device to the network, use method 4 and reset the device to initial status before downloading.

Note When the parameters are downloaded to the devices, the network number is

transferred with the parameters as the UNID and saved in the devices. Therefore, when using a device whose parameters have already been downloaded to another domain, set the reset type to Return to the out-of-box configuration, and then emulate cycling power and perform a reset to clear the UNID.

Creating a Virtual Network Section 3-4

Use the following procedure to set the network number.

1. Select Network - Property from the menu bar.

2. In the Network Number Field, select the Manual Option and enter the val-

ue.

IMPORTANT Always allocate a unique network number when a network or subnetwork is

established.

If the network number is not set correctly, a connection may be opened to a different device. A different network number must be set for each network domain, and the same network number must be set for all the devices on the same domain.

If the network number is set by the user, click the Get from the actual net- work Button in the Network Number Field on the Network Property Dialog Box to check the network number set for the target actual network. The network number set to the target network will be read and displayed in the Man- ual Field.

Creating a Virtual Network Section 3-4

3-4-3 Adding Devices

There are three ways to add a device to the virtual network.

1. Add from the Hardware List.

2. Upload the network configuration from the actual network.

• Uploading for the target network will start if the Yes Button is clicked here.

If there is another device that must be added after the upload has completed, add the device following the same procedure as in Adding Devices from the Hardware List, above.

IMPORTANT If there is a CS/CJ-series DeviceNet Unit in the network, disable the master

function of the CS/CJ-series DeviceNet Unit, or disable I/O communications from the DeviceNet Unit monitor window, and then do the upload. If I/O communications are enabled, uploading the device parameters may fail.

Note • When uploading the network configuration from a network, it can be

uploaded as the configuration or the current network or as a new network.

• When data is uploaded as a new network, the virtual network information that was displayed until will be deleted. If the previous virtual network information is required, save the data before the uploading the network.

Creating a Virtual Network Section 3-4

• When a network in which devices already have a set network number is uploaded, the value that is already set in the devices will be used for the network number.
