ABB DCS 800XA Version 5.1 System Architecture with redundant each connectivity server & Aspect server ,1 nos. history server with application vitrin software.
1. Increase history logs more than6 month to 2 years.
2. Increases event storage 10000 to 50000 for long time
IMHO: This is possible with Base System alone
- Event Storage can be tuned to store 50.000 events/category
- Basic History can host 10.000 primary (and 1-2 secondary per primary) logs*
*) Adjust sample rate and storage period to not exceed 50 GB disk. Each sample in a log consume 24 bytes of disk space. With shorter primaries and slower sampling secondaries the target 2 years/50GB can be met.
*All* server nodes can run Basic History to increase capacity:
AS2: BH1B (redundant)
CS2: BH2B (redundant)
- or - (without redundancy in historian role):
Last example deliver 4x10.000 logs and 4x50GB storage which is a lot.
