How to replace the base on CI867 on a running dual system?
Hello,
i want to replace 2 base`s on the CI867 on a running dual system with PM865, BC810 and SM811 . Is this possible?
My plan is to remove the power from the controller that is not primary, then remove the RCU(redundant)cable on this side only.
Then i will remove the CI867 card and the base and replace it.
Then i will reconnect the power to the PM865 processor and the cables.
Then i will prsse INIT to start up the processor and watch the startup and make sure the DUAL function is ok.
Then i will stopp the processor that is running and do the same procedure here.
The name of the base is TP867, i want to replace this one at a time beacuse the contacts on the Ethernet is corroded.
Does this sounds like a plan or should i do it in another way?
Best regard Nils

Do you have any possibility to try this in a test-envoirment First?
Sounds like it could work. If it was me; i would test it first on my own system in a test envoirment. even if the books says its ok

Hi,
Looking in the manuals, my understanding is that this is not allowed - e.g. 3BSE036351-600 A page 206:
"Baseplates for CI8xx (TP8xx) - Must not replaced online."
On the other side, using of BC810 allows the different segments to be powered off. I believe the question from Nils comes from that point. Somewhere in the manuals I found explanations for online changes, that they are allowed from particular system version above.
My advise is to ask an authorized ABB tech support, if you find such, prior to do the operation on a running system.
At least this test could be done there, in lab conditions. The answer will be interesting for me too.

"It is not allowed to manipulate CEX bus baseplates in a powered and running system. Before changing or removing a baseplate, all CEX modules on that segment must be removed"
I think that ensuring of identical system configuration for doing of check in test environment looks difficult and expensive at customer side. Except if they don't have such a modules as a spare (twice ordered redundant pair of processors, BC's and CI's modules).On the other side, using of BC810 allows the different segments to be powered off.

Hi!
So you have two CI867 in a redundant configuration, where both has to have their respective TP867 base replaced?
Considering these are HI controllers in a Safety System setup, I would for strongly recommend having a risk assessment done, before even considering to proceed.
I would also recommend analyzing application as well, to make sure there are no functional issues (adding to system hardware issues), that will compromise you work (loss of comms/field equipment etc).
Make sure to analyze hazards and obtain approval for your plan.
Finally, make up plan B...
(Maybe this issue can wait for the next planned stop of production?)
Good luck!
