Create and change the program of the NE1A-SCPU01 configured in the virtual network according to
specified changes.
Refer to Section 6: Programming the Safety Network Controller (page 97) 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-examine the specified changes.
Refer to 3-2 Verifying the Network Bandwidth (page 59).
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 3-3 Calculating and Verifying the Maximum Reaction Time (page 63).
14. Saving the Network Configuration File
Save the network configuration file with the completed changes.
Refer to 2-5-2 Saving the Network Configuration File (page 38).
15. Exiting the Network Configurator
Exit the Network Configurator.
The following operations are performed by connecting the Network Configurator to the network after the
actual system changes have been completed.
IMPORTANT: • Allocate a unique network number when establishing a network or subnetwork.
Note: If device parameters with a locked configuration are changed, the color of the key icon will change to
yellow.
Re-configuration
16. Starting the Network Configurator and Connecting to the Network
Start the Network Configurator and connect it to the network via the USB port of the NE1A-SCPU01 or
a DeviceNet Interface Card.
Refer to 2-3 Connecting to the Network (page 32).
17. Reading the Network Configuration File
Read the saved network configuration file with the completed design changes.
Refer to 2-5-3 Reading a Network Configuration File (page 39).
18. Downloading Device Parameters
Download the parameters to all the devices.
Refer to 2-7-3 Downloading Device Parameters (page 41).
19. Confirming the Downloaded Device Parameters and Safety Signature
Verify the parameters for all devices with an icon indicating pre-verification and check if the device
parameters and program that the user input are correctly downloaded and saved to the devices.
Refer to 2-8 Parameter Verification (page 45).
20. Saving the Network Configuration File
Save the configuration file for a network in which parameter verifications of all the devices have been
completed.
Refer to 2-5-2 Saving the Network Configuration File (page 38).
21. Exiting the Network Configurator
Exit the Network Configurator.
IMPORTANT: • After downloading the device parameters, verify the parameters to confirm that the param-
Note: – In the Network Configuration Pane, the device will be displayed as locked, but the actual device has
already been unlocked. Therefore, the parameters can be downloaded.
3-1 Applications
• If the parameters of a Safety Slave or Standard Slave are changed, the parameter infor-
mation will not match in the Safety Master or Standard Master in which the Slave is regis-
tered. 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
Master. Allocate a unique network number when establishing a network or subnetwork
with Safety Slaves.
eters and the safety signature saved in the device 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.
