PI 3.2 Migration
  • PI 3.2 Migration and Goals
  • Why Migrate
  • Technical Issues
  • Interface Issues
  • Challenges
  • OSI Response
  • Overall evaluation
  • Future requests

4
PI 3.2 Migration
  • Why Migrate?
  • OSI development stopped on PI 2.x
  • Archive history too small
  • Other reasons
  • No support for sub-second time stamps
  • Upgrade Maintenance costs to PI 2.x system
  • Higher archive efficiency with No Limit to size
  • Long Tag Names
  • History on CD ROM

5
PI 3.2 Migration
  • Problems Faced with existing system
  • Archive history too small
  • High cost to increase storage space.
  • Any upgrades would only be temporary. (OSI
    stopped development on 2.x)

6
PI 3.2 Migration
  • Migration Considerations
  • Upgrade existing system - v - New Intel Server
  • Cost of Upgrades
  • Training
  • Proven Platform - v- Unknown/New
  • Bleeding Edge syndrome
  • Interface compatibility
  • Home grown software issues

7
PI 3.2 Migration
  • Migration Process
  • I. Buy NT Server and install PI 3.2.
  • Extract Tag/Configuration from PI 2.x
  • Replicate (whats possible) config. tag
    structure.
  • Verify/complete setup of PI 3.2.
  • II. Install PI to PI interface.
  • Run in parallel for verification of archives and
    user tools.
  • III. Direct all user tools to 3.x system for
    user testing/feedback.
  • IV. Install PI 3.2 Interfaces and test.

8
PI 3.2 Migration
  • Process Contd.
  • IV. Direct PI Net Nodes to talk to PI 3.x Home
    Node.
  • V. Turn off PI2PI, convert VMS PI Home node to
    PI Net node. (Maintain home grown apps.)
  • VI. Migrate home grown apps to NT Server Test.
  • VII. Go production

9
PI 3.2 Migration
  • Challenges with Migration
  • Problems with initial installation on NT server.
  • Installation Migration not same as
    documentation.
  • Firewall table, Proxy server, User table (8 Char
    only), PI 32bit API, Logins w/ client tools.
  • Archive size. 300 Meg is our choice. gt 300 Meg
    requires long conversion hours.
  • System almost bogged to standstill. (Processors
    at 99-100 - new build removed bug.
  • No digital state tags at first. Very different
    puppy.
  • Documentation problems.

10
PI 3.2 Migration
  • Challenges Contd.
  • Do Not install Default points. Otherwise you
    will just have to start over again.
  • Create your archives with batch files
  • Minimal prep.
  • Hacker by nature - 1 - 1.5 weeks total time
    from nothing to full up PI 3.2.

11
PI 3.2 Migration
  • Challenges Contd.
  • PI2PI startup problems.
  • Used 1 PT Source at first. Not efficient.
  • Created a Pt Source for each area of mill.
    Easier to handle tags.
  • Consider a PI2PI pt source for each interface in
    future.
  • How to convert from PI2PI to production Tags.
  • Starts at PI3 tag creation during migration.
  • Save Attribute changes for PI3/PI2PI in Excel
    with tag names.
  • Use Jins GUI tools to change PI 3 tags to PI2PI
    req.'s.
  • When ready for production, paste Tags and changes
    into Tag Configurator and run the edits.

12
PI 3.2 Migration
  • Challenges Contd.
  • PI2PI Startup overflowing PI 2 Event Queue.
    Event sign-up with PI 2 BEFORE PI 3 ready to take
    data.
  • Data verification. Resolution not the same on
    servers. (Fixed)
  • PI 3.2 Troubleshooting
  • Use your PI MESS log file! (Pimesslog.txt)
  • Watch Client Tools for updates.
  • Check evm_monitor constantly.
  • PIGetMsg on NT server.
  • Health Check GUI Tools

13
PI 3.2 Migration
  • Issues
  • Digital States.
  • Conversion caused our D.S. tables setup in our
    tags to be unusable.
  • PI2 - Start and Length in configuration
  • PI3 - Sets only.
  • PI 3 Digital Set Features
  • Cannot delete Digital States/Sets
  • Starts with 0 offset.
  • Edit command procedure to add DummySet0.
  • Puts in DummySetX if you try to delete one.

14
PI 3.2 Migration
  • Issues Contd.
  • Create your D.S. Sets with a command Procedure
    output file from PIDiff, then use PIConfig on PI
    3.X. Example

LISTPIDS.TXT
List all Digital State Sets _at_Table PIDS _at_Mode
List _at_Ostructure SET, State, _at_Select
SET _at_Endselect
Usage
C\PI\ADM\PIConfig lt ListPids.txt
15
PI 3.2 Migration
  • Issues Contd.
  • ProcessBook Users.
  • Hex Edit to look at PI 3. (Does not do the
    linked pages in Processbook.
  • GUI management tools
  • TagConfigurator.xls
  • Health Check

16
PI 3.2 Migration
  • Daily Routine
  • Check Processbook for any update problems.
  • Run evm_monitor on PI 2 system to check Event
    Queues for overflow.
  • Check PI Mess log file
  • Check PIGetMsg (PI 3.2 Message log) for any
    errors
  • Check \PIPC\DAT\PIPC.LOG file for interface
    problems

17
PI 3.2 Migration
  • Hardware
  • PI Server - HP Netserver LX Pro
  • Dual Pentium Pro 200Mhz
  • 512 Meg Ram
  • (4) 9gig Ultra Wide SCSI II (app. 24gig usable)
  • HP NetRAID Ultra Wide SCSI Controller
  • RAID 5
  • CDR (On line history storage and backup)
  • 24 gig DDS-3 Tape Backup (7gig/hour backup, NOT
    tested as of yet.)

18
PI 3.2 Migration
  • OSIs Response
  • Excellent!
  • All issues found with PI 3.2 were answered and
    fixed in an expeditious and professional manner.
  • System become more stable with each new build.
  • OSI kept their reputation of being in the
    trenchs with their clients throughout testing
    phase.
  • PI 3.2s technical staff was on top of all bugs
    found and fixed and updates posted in an
    expeditious manner.

19
PI 3.2 Migration
  • Overall Assessment of PI 3.2 - Pros
  • Becoming solid quick.
  • System is easy to use, and understand.
  • PI 3.2 Archives are more efficient. Double to
    triple storage capability.
  • Fast. Client tools took no hit on performance.
  • ODBC - Simple and efficient to utilize.
  • VB 5 Integration
  • Newer capabilities.
  • Cheaper in long run
  • Expandable OTS answer to storage problems.

20
PI 3.2 Migration
  • Cons
  • More GUI Management tools are required to get us
    completely out of command line typing.
  • Documentation.
  • ActiveX ???

21
PI 3.2 Migration
  • Future Requests
  • GUI Management tools
  • GUI PIConfig
  • GUI PIArtool
  • Icon Health check
  • PI
  • Archives
  • Interfaces
