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 3-5-3 Reading a Network Configuration File.
10. Changing the Virtual Network
Add or delete the devices and change the node addresses according to
specified changes.
Refer to 3-4 Creating a Virtual Network.
11. Changing the Device Parameters and Program
Set and change the parameters of the NE1A-series Controllers configured
in the virtual network according to specified changes.
Refer to SECTION 5 Editing Safety Network Controller Parameters
and to the Safety Network Controller Operation Manual (Z906).
Create and change the programs of the NE1A-series Controllers config-
ured in the virtual network according to specified changes.
Refer to SECTION 6 Programming the Safety Network Controller and
to the Safety Network Controller Operation Manual (Z906).
12. 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 specified changes.
Refer to 2-2 Allocating Network Bandwidth Usage and Calculating the
Best EPI.
13. Recalculating 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 specified changes.
Refer to 2-3 Calculating and Verifying the Reaction Time.
14. Saving the Network Configuration File
Save the network configuration file with the completed changes.
Refer to 3-5-2 Saving the Network Configuration File.
15. Exiting the Network Configurator
Exit the Network Configurator.
The following operations are performed by connecting the Network Config-
urator to the network after the actual system changes have been complet-
ed.
IMPORTANT • Allocate a unique network number when establishing a network or sub-
network.
• If the parameters of a Safety Slave or Standard Slave are changed, the
parameter information will not match in the Safety Master or Standard
Master in which the Slave is registered. Therefore, a yellow [ ! ] symbol
will be displayed next to the slave icon. If this symbol is displayed, check
the slave information by opening the Edit Parameter Window of the Mas-
ter. Allocate a unique network number when establishing a network or
subnetwork with Safety Slaves.
