Establishing a New Safety Network

System Design and Programming
IMPORTANT Allocate a unique safety network number to each safety network or safety

This section describes how to construct a DeviceNet Safety Network in the
following two cases.
1. Establishing a new Safety Network
2. Changing an established Safety Network
This section describes the procedure for establishing a system by designing a
new Safety Network using the Network Configurator and then downloading
the parameters to the network devices.
1. Starting the Network Configurator
Start the Network Configurator.
Refer to 3-1-1 Starting and Exiting the Network Configurator.
2. Creating the Virtual Network
Create the virtual network by adding a device from the Hardware List. If the
user is to specify the network number, set the network number as well.
Refer to 3-4 Creating a Virtual Network.
3. Editing and Programming Device Parameters
Set the parameters of the NE1A-series Controller configured in the virtual
network.
Refer to SECTION 5 Editing Safety Network Controller Parameters
and to the Safety Network Controller Operation Manual (Z906).
Program the NE1A-series Controllers configured in the virtual network.
Refer to SECTION 6 Programming the Safety Network Controller and
to the Safety Network Controller Operation Manual (Z906).
4. Verifying the Network Bandwidth to Use
Confirm that the bandwidth used in the safety I/O communications does
not exceed the acceptable bandwidth in the network. If exceeded, re-ex-
amine the procedure from network configuration in step 2.
Refer to 2-2 Allocating Network Bandwidth Usage and Calculating the
Best EPI.
5. Calculating and Verifying the Maximum Reaction Time
Calculate the maximum reaction time of all the safety chains and check if
the requirement specifications are met. If the requirement specifications
are not met, re-examine the procedure from network configuration in step
2.
Refer to 2-3 Calculating and Verifying the Reaction Time.
6. Saving the Network Configuration File
Save the network configuration file with the completed design.
Refer to 3-5-2 Saving the Network Configuration File.
7. Exiting the Network Configurator
Exit the Network Configurator.
The following operations are performed by connecting the Network Config-
urator to the network after the network installation and wiring.
