CompactLogix Backup on the DeviceNet Network Appendix B
Backup System Requirements
The CompactLogix backup on DeviceNet solution requires that you use the
following:
• RSLogix 5000 programming software, version 10 or later
• Two CompactLogix controllers, firmware revision 10.x or later
• Two 1769-SDN scanner modules, firmware revision 3.x or later
Additional requirements are as follows:
• When setting up the DeviceNet network, you must set the primary and
secondary 1769-SDN scanner modules to the same node address and
reserve the next node address.
We recommend that you set the primary and secondary 1769-SDN
scanner module node addresses to 0 and reserve node 1. However, you
can use any successive node numbers (for example, 30 and 31).
• All I/O and operator interfaces that required backup must be on the
DeviceNet network.
• The scanlists in the two DeviceNet scanner modules must be identical.
