[1]NI 985x C Series CAN modules automatically sync to all NI CompactRIO modules on the backplane with a shared timebase. External sync requires a digital module.
[2]NI-XNET devices are backward compatible with existing NI-CAN Channel and Frame API code and NI toolkits with the NI-CAN Compatibility Library. Learn more about the compatibility library.

Frame API is supported on the cRIO
Based on this KB
http://digital.ni.com/public.nsf/websearch/AA00DAA60674200C86257279007C3A50?OpenDocument
The Frame API is supported for the cRIO...you
should change the check mark in the table...
