CompactLogix Backup on the DeviceNet Network Appendix B
9. Connect the other CompactLogix controller with a 1769-SDN scanner
module on the network.
10. Set the node address to 0.
11. Apply power to the controller and scanner module.
12. Use RSNetWorx for DeviceNet software to download the same scanlist
used in
step 5 .
It may be necessary to browse the network again before downloading
the scanlist. This second browsing of the network allows RSNetWorx
for DeviceNet software to establish communication to the new scanner
module at the same node number as the previous scanner.
13. Use RSLogix 5000 programming software to download the user
program to the second CompactLogix controller as you did in
step 6 .
Typically, you download the same user program to the second
CompactLogix controller as you did to the first. However, unlike the
scanlists, the user programs in the controllers do not have to be
identical.
14. Put the controller into Run mode.
This controller is now ready to use and is the primary controller.
15. Reapply power to the secondary controller and/or reconnect the
secondary scanner module to the DeviceNet subnet.
This completes the backup process. For more detailed information on some of
the steps listed previously, see the next section.
