Upgrading to CI854 from CI851
I have PM856 (AC800M) controller & CI851 module (CI830 as Slave). I would like to upgrade the existing CI851 with CI854. But i have few doubts:
1) Does CI854 support CI830?
2) In my Hardware Structure, if i right click over CI851 and select "Replace Unit" and choose CI853 my existing Subunits are deleted (DI & DO's ) giving additional work to configure all inputs & outputs again. Any option available to eliminate the work of reconfiguring the Subunits(like DI801, DO801 and associated IO's) during upgrade?

1) Yes, CI854 support CI830
2) Reg. reconfiguring of subnets, May be what you can do is take a bdm of the subnets before replacing the module. This way you will archive the older information.
After replacing the module, you can change the path manually in the BDM before uploading to the system so that it don't give error and gets restored successfully..
You can also insert new module using the same BDM, this will avoid the manual work.
Hope this helps!!!
