DeltaV Historian Comparison

Is there any Emerson Documentation comparing the capabilities of the DeltaV Continuous Historian, Advanced Continuous Historian, and the Enterprise Historian?

From what I can tell the continuous historian cannot send data to an outside server you will need at least the advanced license for that. The enterprise license allows for an integrated PI/DeltaV server. If there is no Emerson documentation am I missing anything big in the comparison?

If you buy the enterprise historian licenses is that all you need? 

Thanks,

alex

  There is a whitepaper that compares the options - there is a lot to consider:
  www.emerson.com/.../white-paper-deltav-historian-options-en-58628.pdf
  
  It's a bit out of date (doesn't cover DeltaV Live integration, some limits are out of date). You should read the associated data sheets and whitepapers about the different historians, too. All available here in the documents and drawings section:
  www.emerson.com/.../deltav-advanced-continuous-historian
  
  It depends on what you mean by "cannot send data to an outside server". The DeltaV Continuous Historian data can be accessed via OPC HDA.
  
  The ACH is somewhat of an integrated PI/DeltaV server since the ACH "uses OSI PI technology". It depends on how much of an OSI PI you want / expect to have.
  
  If you buy the enterprise historian license, you will also need to buy OSI PI licenses for the OSI PI components and application station licenses to get the required OPC tags. There may be others I am forgetting. You should really work with your local sales office to determine everything you need.
  
  Hope this helps.

  The first whitepaper was the one I was looking for. Thanks!
  
  I don't have a project in mind just reading up on current options. Thanks!

  Brian covered pretty much everything.
  
  The Advanced Historian use a PI enterpise historian with restrictions on what you can use it for. It is intended for DeltaV data only and is licensed within DeltaV.
  
  DVCH comes with a single connection OPCHDA server. You can expand that to a multi connection server. OSI has a scanner that will pull data from DVCH and serve an Enterprise historian.
  
  If you are using PI at the Enterprise level ACH makes sense and comes with PI to PI integration.
  
  If you dont use PI at the enterprise level, DVCH will be a better fit.
  
  Note that ACH can collect up to 60K tags while DVCH tops out at 30K. However ACH does not store status. If you want to store status and value that requires 2 tags in ACH but only one in DVCH.
  
  DVCH has a limit on Current datasets at 10 GB. You have to manually run a convert utility and move data into extended data sets. With extended datasets you are not limited to on line history but there is periodic maintenance. ACH allows you to define as much space as you want for history.
  
  If data quality is important I would recommend DVCH.
