Maxi(mum) Backplane MAC ID is an attribute for 1734-ADNX only. This value represents the highest
node address of a module residing on the backplane. The value must be greater than or equal to the
right-most backplane Subnet module, but less than that of any non-backplane Subnet module.

- Device is not powered. - Check
module status indicator. Check adapter status
indicator to determine if you
need more time to complete

Max backplane MAC ID is not
set right (1734-ADNX). Make sure all I/O modules
are connected and using the
correct MAC IDs.
Check “Cycling Node
Status” parameter in
RSNetWorx for DeviceNet.

correctly set the Max
Backplane MAC ID.

Red Critical link failure -
communication device failed.
Device detected error that
prevents it from communicating
on the network. Make sure an I/O module is
not using a MAC ID =0.
Make sure all backplane
modules are communicating
at the proper baudrate.
