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.

1-5-3 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 2-7 Device Parameters and Properties (page 41).

• Verification

• Refer to 2-8 Parameter Verification (page 45).

IMPORTANT: • After downloading the device parameters, verify the parameters to confirm that the param-

eters 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.

1-5-4 User Test

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 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.
