AC410 Halt code FF
While powering up an AC410 node , the node goes to halt mode with halt code FF.
On doing a init, it comes to halt code 05 and then immediately goes to FF again
Any suggestions to rectify the same?
In the manual, halt code 05 = Bus fault.
Yep. Thats pretty serious.
"> The halt codes 0 - 5 do not normally appear in a
system after commissioning but if one should appear,
it is probably due to interference, program error or
special hardware fault."
You *might* be able to do a LSYSHI on the stopped CPU to see why it failed, but this probably isnt going to help you anyway. I suspect that the system halt information is already lost. Even if it isnt its going to tell you the halt code is "05"
If the controller will not warm start ( init switch Switch in P1 or P2) then you will need to cold start the controller. (If you have had any sort of fault code that halts a running AC400 controller I would personally always cold start from a DUAP anyway as the application may have been corrupted)
Check the Position of the Start Switch (P3 Clear)
Load a recent clean working DUAP backup using the LOAP command.
If that doesn't resolve the problem ...
Call your local ABB support line and log an urgent supportline case. If you dont have spares on site you may need them in a hurry.
Pull any S100 I/O, submodules and other boards in the rack and retry
Change the Firmware PROM Card and retryChange the CPU and retry
