Changing an Established Safety Network

This section describes procedure to change the Safety Network after the system is running.
Changing the System
1. Stopping the System
Turn OFF the power supplies to moving parts, such as motors, and stop the system. Continue supplying
power to the network and the NE1A-SCPU01.
2. 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 2-1-1 Starting and Exiting the Network Configurator (page 27) and 2-3 Connecting to the Net-
work (page 32).
3. Uploading the Network Configuration
Upload the network to obtain the current network configuration.
Refer to 2-4 Creating a Virtual Network (page 34).
4. Unlocking the Configurations
Unlock the configurations of all the devices to enable changing the network configuration.
Refer to 2-9-2 Unlocking the Device Configuration (page 48).
5. Resetting a Device
Before changing device parameters and node address, clear the configuration of the device. Reset the
device by setting the reset type to Return to the out-of-box configuration, and then emulate cycling
power.
6. Exiting the Network Configurator
Exit the Network Configurator.
7. Changing the System
Change the network, wiring, and node addresses and add or delete devices according to the specified
system changes. Safety devices that are being newly added must be configured in advance.
Safety functions may be impaired and serious injury may occasionally occur. Before connect-
ing a device to the network, clear the previous configuration data.
Safety functions may be impaired and serious injury may occasionally occur.
Before connecting a device to the network, set the appropriate node address and baud rate.
Note: There is no need to use the saved network configuration file, because the purpose of this procedure
is to unlock the device configurations and reset devices to the default configurations.
Redesigning the System
8. Starting the Network Configurator
Start the Network Configurator to redesign the network.
9. Reading the Network Configuration File
Read the saved network configuration file with a locked configuration.
Refer to 2-5-3 Reading a Network Configuration File (page 39).
10. Changing the Virtual Network
Add or delete the devices and change the node addresses according to specified changes.
Refer to 2-4 Creating a Virtual Network (page 34).
11. Changing the Device Parameters and Program
Set and change the parameters of the DST1-series I/O Terminals configured in the virtual network
according to specified changes.
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 and change the parameters of the NE1A-SCPU01 configured in the virtual network according to
specified changes.
Refer to Section 5: Editing Safety Network Controller Parameters (page 79) and to the Safety Network
