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 third­party organization (TUV Rhineland).

Just as with DeviceNet, DeviceNet Safety-compliant devices from third-party vendors can be connected to a
DeviceNet Safety network. Also, DeviceNet-compliant 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.

1-5 Basic System Startup Procedure

This manual introduces the basic steps that are needed to make the safety system operational, with particular
focus on the following steps.

– System Design and Programming
– Configuration
– Testing

1-5-1 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 deter-

mine 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-SCPU01.

• 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-SCPU01 and Safety I/O Terminal parameter settings, and NE1A-SCPU01 pro­gram, so repeat the steps above to determine a system configuration which meets the users' requirements.

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 2-9 Configuration Lock (page 48) for details on performing a Configuration Lock from the Network
Configurator.

IMPORTANT: • After configuring all the devices, user testing must be performed to check if the configura-

tion data and device operation of each device are correct. User testing is performed to ver­ify the safety signature for each device.

• The configuration must be locked after the user testing has completed.

34 Section 2: Basic Operation of the Network Configurator

2-4 Creating a Virtual Network

To set device parameters and to program the NE1A-SCPU01, create a virtual network in the Network Con­figurator, set the device parameters in the virtual network, and then download them the parameters to the
actual devices.

This section describes how to create a virtual network.

2-4-1 Creating a New Virtual Network

When the Network Configurator is started, a new virtual network can be created.
Only one virtual network can be edited simultaneously. Use one of the following methods to create another

network.
(1) Select File - New from the menu bar.
(2) Click the New Button on the toolbar.

Note: When a new virtual network is created, the virtual 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.

2-4-2 Network Numbers

The network number (i.e., the network address) is the number set for each network domain. All devices on
the same network must have the same network number.

The network number is set as a unique node identifier (UNID) in combination with the node address from the
Network Configurator and saved in the device. UNID is used to identify one device from all the network do­mains.

The Network Configurator automatically creates the network number based on the time and date when a new
network configuration file is created. Under normal conditions, the user does not have to consider this oper­ation.

Note: When the parameters are downloaded to the devices, the network number is transferred with the pa-

rameters 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.

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 value.

IMPORTANT: Always allocate a unique network number when a network or subnetwork is established.

2-4 Creating a Virtual Network 35

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.

2-4-3 Adding Devices

There are two ways to add a device to the virtual network.
(1) Adding from the Hardware List.
(2) Uploading the network configuration from the actual network.

Adding Devices from the Hardware List

There are two ways to add a device to the virtual network from the Hardware List.
(1) Double-click the selected device in the Hardware List.
(2) Select the device from the Hardware List and drag it to the Network Configuration Pane.
When a device has been registered, it will be displayed as follows:

Uploading the Network Configuration from the Actual Network (Network Upload)

The network configuration can be read from the actual network and to create the same configuration in the
virtual network. Connect the Network Configurator to the network, and then upload the network configuration
using any of the following methods.

(1) Select Network - Upload from the menu bar.
(2) Click Upload from Network on the toolbar. Uploading will start, and the detected devices will be dis-

played sequentially.

36 Section 2: Basic Operation of the Network Configurator

(3) Right-click without selecting any device in the Network Configuration Pane and select Upload.

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: When the CS/CJ-series DeviceNet Unit exists in the network, disable the master function-

ality of the CS/CJ-series DeviceNet Unit, and then do the upload. If the master functionality
is enabled, uploading the device parameters may fail.

Note: – When a network is uploaded, the virtual network information that was displayed until then will be

deleted. If the previous virtual network information is required, save the data before the network up­load.

– When a network in which devices already have a set network number is uploaded, the value that is

already set in the devices is used for the network number.

2-4-4 Deleting Devices

There are three ways to delete a device from a virtual network.
(1) Select a device, and then select Edit - Delete from the menu bar.
(2) Select a device, and then click the Delete Button on the toolbar.
(3) Select a device, and then right-click the selected device and select Delete.

3-2 Verifying the Network Bandwidth 59

3-2 Verifying the Network Bandwidth

Approximately 100% of the network bandwidth in the DeviceNet can be used. If the setting exceeds the ac­ceptable bandwidth, however, timeouts will occur.

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

3-2-1 Checking the Network Bandwidth Used for Safety I/O Communications

In the lower portion of the network window, the Network Configurator displays the percentage of the network
bandwidth used for safety I/O communications from the connections set in the virtual network.

The percentage of network bandwidth used is displayed for each baud rate.
Performing Only Safety I/O Communications
When performing only safety I/O communications, there is no problem if the network bandwidth used for safe-

ty I/O communications is approximately 90%.
If bandwidth exceeds 90%, obtain the average EPI by referring to the next section and use it as the reference

for setting connections.

IMPORTANT: Keep 10% or more space in the network bandwidth for establishing a connection and for

communications of the Network Configurator. If the user application uses explicit message
communications, additional network bandwidth is necessary. In this case, decide the net­work bandwidth for the explicit messaging in consideration of the amount of the data and
the frequency of the communications.

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

When both safety I/O communications and standard I/O communications are mixed on one network, it is nec­essary to determine the network bandwidth to use for each communication. In this case, check that the net­work bandwidth used for safety I/O communications does not exceed the determined value.

The Network Configurator can calculate the average EPI by the user entering the network bandwidths to use
for communications. Set the EPI for each safety connection and the communications cycle of the Standard
Master referring to this value.

60 Section 3: Constructing a Safety Network

3-2-2 Allocating Network Bandwidth

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

Calculate the EPIs using the following procedures:

1. Set the virtual network on the Network Configurator as needed.

2. Click the EPI Calculation Button in the lower portion of the Network Configuration Pane.

3. Input the network bandwidth used in safety I/O communications and the bandwidth used in standard I/O
communications, and then click the Calculate Button.

4. The average EPI of all the connections in the safety I/O communications and the communications cycle
time in the standard I/O communications will be displayed for each baud rate. Review the EPIs for safety
I/O communications and the communications cycle time of the Standard Master referring to the baud rate
that is to be used.

IMPORTANT: • Keep 10% or more space in the network bandwidth for establishing a connection and for

communications of the Network Configurator. If the user application uses explicit message
communications, additional network bandwidth is necessary. In this case, decide the net­work bandwidth for the explicit messaging in consideration of the amount of the data and
the frequency of the communications.

• The calculation result is the average value of all the safety connections. Use this value as
a guideline. Adjust the EPI for the whole network by shortening the EPI for connections
that require a high-speed reaction time and lengthening the EPI for connections that do
not require high speed.

• Check that the displayed usage rate in the lower portion of the Network Configuration
Pane is the allocated value or less when adjusting the EPI of the whole network based on
the calculation results. Communications timeout might occur if the calculated bandwidth is
not properly allocated to the standard connections because the priority of safety I/O com­munications is higher than that of standard I/O communications.

• The total network bandwidth used in the safety connections and the standard connections
must be around 90% at the maximum, i.e., 10% or more available bandwidth must be left
for explicit message communications.

• Perform user testing to make sure that there is no problem in the set values.

Note: – If you do not want to mix with standard I/O communications, set the network bandwidth used for

standard connections to 0.

– The EPI is set in 1 ms increments. The network bandwidth to be used may thus be smaller than the

allocated value when the calculated value is used.

3-2 Verifying the Network Bandwidth 61

3-2-3 Example of EPI Calculation

The following network configuration is used for an example of calculating the EPI. The baud rate is 500 Kbit/s.

The NE1A-SCPU01 sets safety connections between four DST1-ID12SL-1 Input Terminals and four DST1­MD16SL-1 I/O Terminals. The default set values are used for all the safety connections, and the EPI is 10 ms.

Also, the CJ1W-DRM21 sets the standard connections between four DRT2-ID16 Input Terminals and four
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.

62 Section 3: Constructing a Safety Network

Here, we allocate 70% of the network bandwidth to safety connections and 20% to standard connections.
From the calculation results, you can see the EPI for the safety connections can be set to 7 ms and the com-

munications cycle of the Standard Master can be set to 6 ms.

Following the calculation results, set the EPI of all safety connections set in the NE1A-SCPU01 to 7 ms.

Also, set the communications cycle of the CJ1W-DRM21 to 6 ms.

3-3 Calculating and Verifying the Maximum Reaction Time 63

3-3 Calculating and Verifying the Maximum Reaction Time

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

3-3-1 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) NE1A-SCPU01 Standalone System

(2) Remote Input - NE1A-SCPU01 Output

(3) NE1A-SCPU01 Input - Remote Output

(4) Remote Input - Remote Output

Note: Even if a fault or failure occurs in a safety chain, the output shutoff time is ensured as the maximum

reaction time.

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

3-3-3 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-SCPU01 cycle time is automatically calculated based on the program size, the number of
connections, etc. It is also possible to use different NE1A-SCPU01 Controllers for safety chains that
require a high-speed reaction time and other safety chains.

5-1-2 Setting Safety Connection Parameters

This section describes how to set safety connection parameters.

I/O Connection

Select the assembly to use from the I/O assemblies that the destination Safety Slave supports.
Note: – Refer to the DST1-Series Safety I/O Terminals Operation Manual (3-2 Remote I/O Allocations) for

I/O assemblies that the DST1-series Safety I/O Terminals support.

– When the Safety Slave function of the NE1A-SCPU01 is used, the I/O assembly must be set in the

Safety Slave I/O Window. Refer to 5-2 Safety Slave Settings (page 84).

Open Type

Select the type of open processing to be performed when the NE1A-SCPU01 establishes a connection with
the Safety Slave.

IMPORTANT: Check that the Safety Master and the Safety Slave are configured correctly when selecting

Open only as the safety connection open type.

Note: If the Safety Slave is not configured when Configure the target device is specified, the NE1A-SCPU01

configures the Safety Slave and then establishes a connection. Therefore, the communications can
be started again just by connecting the slave to the network without the Network Configurator when
the Safety Slave is replaced. In the current version, however, the parameters to be set are only those
related to the safety application. When standard parameters do not need to be set, this open type can
be specified. The ability to set standard parameters is planned for future development.

Open Type Description

Configure the target
device

The Safety Slave is configured when the connection is established. The parameters
that can be set are limited to the parameters relevant to the safety application. Do not
use this open type under normal conditions.

Check the safety
signature

The NE1A-SCPU01 sends the safety signature of the slave when the connection is
established. The safety signature is checked in the Safety Slave that receives a con­nection is established. Specify this open type when establishing a connection with
DST1-series Safety I/O Terminals.

Open only The NE1A-SCPU01 does not send the safety signature of the slave when a connec-

tion is established. The Safety Slave establishes the connection without checking the
safety signature. To use the slave function of the NE1A-SCPU01, it is necessary to
configure the Safety Slave correctly from the Network Configurator. If it is not correctly
configured, a connection will not be established, so there is no need to send the safety
signature from the Safety Master for checking. Only this open type can be selected
when the slave is the NE1A-SCPU01.

5-1 Safety Connection Settings 83

Connection Type

Select the connection type to use between the NE1A-SCPU01 and Safety Slave.

EPI (Expected Packet Interval)

The EPI is the interval at which the Safety Slave communicates the safety data with the NE1A-SCPU01. The
minimum set value is the greater of the destination Safety Slave cycle time and NE1A-SCPU01 cycle time.

The cycle time of the DST1-series Safety I/O Terminals is always 6 ms. Check the cycle time of the NE1A­SCPU01 in the Mode/Cycle Time Window when all the parameter settings and programming have been per­formed.

The time set here affects the network bandwidth and the network reaction time. For information on the net­work bandwidth, refer to 3-2 Verifying the Network Bandwidth (page 59) and for information on the network
reaction time, refer to 3-3 Calculating and Verifying the Maximum Reaction Time (page 63).

Advanced

The Advanced Button enables changing more detailed communications parameters. These parameters af­fect system operation; do not change them under normal conditions.

Connection Type Description

Multi-cast
connection

This connection type can be selected only with a Safety Input Slave. When a multi­cast connection is selected, a Safety Input Slave can transmit the input data to a max­imum of 15 NE1A-SCPU01 Controllers via a multi-cast connection.

These NE1A-SCPU01 Controllers are classified as the same multi-cast group when
multiple NE1A-SCPU01 Controllers establish a multi-cast connection with one Safety
Slave and the I/O assembly and EPI values specified in I/O Connection are the same.

This connection type can be selected even for one NE1A-SCPU01.

Single-cast
connection

This connection type can be selected for an input connection or output connection.
The NE1A-SCPU01 and the Safety Slave establish a 1:1 connection and send safety
data.
