Establishing a New 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.
System Design and Programming
1. Starting the Network Configurator
Start the Network Configurator.
Refer to 2-1-1 Starting and Exiting the Network Configurator (page 27).
2. Creating the Virtual Network
Create the virtual network by adding a device from the Hardware List. If the user is to specify the net-
work number, set the network number as well.
Refer to 2-4 Creating a Virtual Network (page 34).
3. Editing and Programming Device Parameters
Set the parameters of the DST1-series I/O Terminals configured in the virtual network.
Refer to Section 4: Editing Safety I/O Terminal Parameters (page 69) and to the DST1 Series I/O Termi-
nal Operation Manual (Z904).
Set the parameters of the NE1A-SCPU01 configured in the virtual network.
Refer to Section 5: Editing Safety Network Controller Parameters (page 79) and to the Safety Network
Controller Operation Manual (Z906).
Program the NE1A-SCPU01 configured in the virtual network.
Refer to Section 6: Programming the Safety Network Controller (page 97) 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-examine the procedure from network configuration in step 2.
Refer to 3-2 Verifying the Network Bandwidth (page 59).
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 configu-
ration in step 2.
Refer to 3-3 Calculating and Verifying the Maximum Reaction Time (page 63).
6. Saving the Network Configuration File
Save the network configuration file with the completed design.
Refer to 2-5-2 Saving the Network Configuration File (page 38).
7. Exiting the Network Configurator
Exit the Network Configurator.
The following operations are performed by connecting the Network Configurator to the network after the
network installation and wiring.
IMPORTANT:
Configuration
8. Starting the Network Configurator and Connecting to the Network
Start the Network Configurator and connect it to the network via the USB port on the NE1A-SCPU01 or
a DeviceNet Interface Card.
Refer to 2-3 Connecting to the Network (page 32).
9. Reading the Network Configuration File
Read the saved network configuration file with the completed design.
Refer to 2-5-3 Reading a Network Configuration File (page 39).
10. Resetting a Device
When changing the configuration because of user testing results or when downloading the parameters
again, it is necessary to clear the previous configuration before downloading the new parameters.
