How much shared memory is provided by 6DD1611-0AG0?
Two separate 2 MB areas provide a total of 4 MB for the two bus systems.
Which backplane buses are coupled by 6DD1611-0AG0?
The module provides coupling memory for both the L-bus and the C-bus.
Does 6DD1611-0AG0 include bus termination?
Yes; termination for the C-bus and L-bus is integrated.
How is retained data supported on 6DD1611-0AG0?
The rack 3.4 V buffer battery maintains the documented data-retention function.
What does the fault relay on 6DD1611-0AG0 indicate?
The integrated relay provides the system-fault signalling function for the module arrangement.
What should be checked before replacing 6DD1611-0AG0?
Confirm rack position, neighboring CPUs, bus configuration, buffer battery condition, memory use and the saved application.
Compatibility & Ordering Notes
Compatibility Checklist
- Use the module only in a SIMADYN D rack arrangement that specifies the MM4 coupling memory.
- Maintain the documented placement between the first and second CPU so both bus paths are correctly terminated.
- Back up the application and verify the rack buffer battery before exchanging the module.
