4-6 Manage the Safety Network Number
SNN and Node Address
Changes If you want to change the address of a safety device, the Safety
Network Number must be uninitialized, or you must first reset the
Safety Network Number.
To reset the SNN:
1. Select the device in the hardware graphic view.
2. From the Device menu, choose Reset Safety Device.
3. Check the Safety Network Number checkbox on the Reset Safety
Device dialog and click on Reset.
Only the attributes selected on the dialog are reset to their
factory default settings. The Safety Reset only affects the safety
device; the configuration in the RSNetWorx project is not lost.
See Safety Reset (Optional) on page 3-4 for more information on
the Safety Reset function.
TIP
After the safety reset, the node address may be
changed in RSNetWorx for DeviceNet by
double-clicking on the safety device’s node
address in the graphic view. After changing the
node address, right-click on the device and
click Download to Device to restore the safety
device’s SNN and configuration.
