CDR - details
• Allows directly query foreign systems
– no data copying
– always actual data
client
AF
CDR
IDS
• Based on PI AF SDK, written in C#
– derived from AFDataReference
– few lines of code
– many options

CDR - configuration
• Custom configuration dialog
– allows to search points
– works transparently
• Generates config string
– for example pid=13
• PI System Explorer
– shows immediately
value

What’s behind - CDR
• Combining data from AF
– PI Server WAMS
– IDS Custom Data Reference
• Solved with Custom Data Reference based computation
– Written in C# using PI AF SDK
– Computed using Math.NET library
• Result is simply another data source for AF
– AF doesn’t care where you take the data and that’s great!

Custom Data Reference conclusion
• Pros
– Allows integrate existing/new system to AF without copying
data to PI Server
– Always online data
– Easy to write
– Freedom of implementation
– No license limitation
• Cons
– typically slower than data directly from PI
– some architecture issues needs workaround

Leveraging the PI System in existing
infrastructure
COMPANY and GOAL
Picture / Image
SW for dispatch control department wanted to
reduce the time needed for system maintaining
and wanted to increase competitiveness
CHALLENGE
Company
Logo
SOLUTION
Many stand-alone systems,
unordered datasources
Use PI as available common
storage and AF with CDR
as transparent interface
• Many systems demand data from
each other
• Causing data duplicity
• Causing unwanted network
loading
• Suppliers are given tools and
possibilities to implement their
projects in compliance with
standards
EMEA USERS CONFERENCE • BERLIN, GERMANY
RESULTS
Overall lower costs and
investments into
infrastructure and ability to
serve demands on our own
• No need to implement another
historian
• No need to implement another
interface
