1 Value-Added Applications in the PI environment St-Laurent Paperboard, La Tuque By Yves Racette, Walsh Automation Inc., PI Systems Integrator

2 Agenda Facts: La Tuque Mill Project and Systems History Systems Architecture Overview of Value-Added Applications Projected work Benefits

3 La Tuque Mill: Facts ~ 1,200 Metric Tons/day - rolled board ~ 50 different grades 3 Kamyr Digesters, 19 Batch Digesters 2 Bleach Lines 2 Paper Machines 2 Power Boilers, 3 Recovery Boilers 3-line Recaust (slakers, lime kilns) Coordination is a constant challenge

4 Systems History Plant Information systems have been in operation at the plant since 1967 –IBM 1800 –PDP-11 –VAX (First version of WalshCIM) –PI Supervisory controls were progressively moved to the DCS

5 1967 IBM 1800 Systems History PDP-11 VAX PI Supervisory Controls DCS

6 Project History Preliminary and detailed Engineering –Needs analysis –Implementation Plan –Costs Estimation Main Objectives: –Replace VAX systems –Long Term Archiving with full resolution –Better diagnostic tools –Migration of VAX applications

7 Architecture (Phase I) PI Server Foxboro I/A Interfaces VAX Bleach. VAX Kamyrs Functions: Data Acquisition Manual Entries PDP-11 I/O Subs. Foxboro Machine 4 Foxboro Effluent Foxboro Machine 3 Foxboro Steam Foxboro Batch Cook Existing VAX PINet Control Network (Ethernet) Plant Ethernet MCS Max 1000 DCS MCS Max 1 DCS PI-API Specific Interface Functions: Data Acquisition Graphics On-line calculations Reports Process Diagnostics

8 Architecture (Current) PI Server Foxboro Machine 4 Foxboro Effluent Foxboro Machine 3 Foxboro Steam Foxboro Batch Cook Control Network (Ethernet) Plant Ethernet MCS Max 1000 DCS MCS Max 1 DCS Functions: Data Acquisition Graphics On-line calculations Reports Process Diagnostics Manual Entries Foxboro Caustic Max Plus Gateway Max Plus Interface Foxboro I/A Interfaces

9 MillWide Use 80 Process Book 20 Datalink 15 Manual Entry Applications (API) 20 SQC 20 Batch View Increasing demand...

10 Applications Design Standards were defined at the beginning of the project –tags and files naming conventions –display standards (color, font, frames, VB code) –reports presentation and automation –development methodology Implementation was done by Walsh Automation and St-Laurent Paperboard

11 Applications Process Book Displays Process Diagnostics (advisors) PI Batch and PI SQC applications Operation Reports Manual Entries On-Line Calculations Specialized applications

12 Process Book Displays Mill and Area Overviews + some details One single.piw file with links to.pdi files NT security implementation (read-only access to.piw and.pdi files) Process Book security: View only mode ProcessBook=Primary (procbook.ini) Navigation toolbar and Detail … menu

13 Process Book Displays Secured PCs: Process Book is the only visible application. All other programs executed from within Process Book VBA code in many display pages (e.g.: on- line calculation of pulp inventory, yesterdays averages, double-clic assigned to Revert) French version of Process Book

14 Live Process Equipment Statuses Navigation Toolbar View Only Mode

15 Process Advisors Specialized displays with visual indications of abnormal process conditions Example: Mill water balance

16 Sewer with abnormal conditions Get details...

17 Tank Overflowing causing the problem Suggested Steps and Actions

18 PI Batch Application Coating kitchen monitoring Batch View OCX and VBA code –After selection of a specific batch, the display time is set to start of batch –VB controls allow for batch replay VBA code validates presence of Batch View license before page is displayed Batch Query/Datalink batch report

19 Batch Selection with Batch View OCX Replay Batch with (+/- delta seconds) Go to Beginning/End of BatchBatch Data (from selection)

20 PI-SQC Application Monitoring of ISO related performance indices VBA code validates presence of PI-SQC license before page is displayed

21 Operation Reports Excel and Datalink combination Created a library of reports automation functions - saved as an Excel add-in (.xla) Daily / Monthly Reports in same spreadsheet ActiveX control for date/month selection Data filtering based on process unit status - blank if process is shutdown or if no manual entry values are available

22

23 Manual Entries PI-Manual Logger data entry could not be used - too complicated for required mill usage and available in english only Data entry application developed by Walsh using Visual Basic –Uses database as configured by PIML –Ease of use / French language –Supports all PIML functions (except HHT)

24 ToursTour Runs Validation bar for selected tag

25 On-line calculations VAX legacy system included a long series of Fortran calculation programs that had to be migrated - some were quite complex ! Performance Equation was not appropriate On-line calculation server (NT service in PI server) was developed by Walsh Synchronized execution at various frequencies

26 Applications are developed in Visual Basic (structured programming - not event) Programs can be easily developed by system engineers Allows for complete documentation with detailed comments On-line calculations

27 Uses VB enumerated tag list to allow use of tags by names instead of by ID with PI-API ActiveX applications are modified and replaced without restarting the schedule service On-line calculations

28

29 Area Specific Applications Area specific applications were developed and integrated within the Process Book environment –Liquor tests –Lime kilns production rate calculations –Operation Log Book –Document Browser (access to reports, ISO and reference documents, …)

32 Training ~ 5 weeks of training by Walsh and Cogexel: –La Tuque trainers (operation) –Users (PB, DL, Manual Entries) - use of applications only –PI System Administrators

33 Projected Work for This Year New PI Server for Profiles Communication link with MAJIQ Replix server (quality and finished product data) Expansion of PI-Batch for complete grades monitoring

34 Benefits Mill users empowerment was immediate Improved personnel productivity Process Diagnostics: improved reaction, reduced duration of problems Improved tracking of equipment downtime Although not essential for production PI has become a critical tool for all users
