Agenda






System Platform 3.0 Approach

► Naming Conventions► Modelling and Standards► Deployment Considerations► Archestra Graphics► Automatic Tag Linking► Instantiating Objects► Addressing Software Problems

Naming Conventions

► P&ID derived naming convention was used for all object instances:

<site>_<area>_<equip>_<instr>_<signal>

Example: 90_DS50_PU15_FIT01_FI

► Define Template, Attribute, Script and Graphics naming conventions

► Do Your Engineering Upfront:▪ Naming Specification▪ Functional Specification▪ Detail Design Document▪ Thin-slice Archestra templates

► Wonderware Best Practices Guideline

► Wonderware System Platform Checklist

► S95 Standards

Modelling and Standards

Process CellProcess Cell

Deployment

► “Fine Tuning and Optimisation of WW System platform”

► Utilise Archestra’s multi-threading capabilities on multi-CPU servers:▪ Multiple application engines▪ Prime number scan intervals for

scan groups

Graphics Approach

► Graphic building blocks were created in the Graphics Toolbox

► The building blocks were grouped in Toolsets

► Graphic building blocks were used to create Object Graphics

► SCADA mimics were created as Local Graphics in the Area instances

► No graphics were created in Intouch - Each Intouch page contains a single Archestra symbol

Graphics Toolbox

► Create all Graphics Symbol building blocks in the Graphics Toolbox

► Graphic Symbols grouped in Graphic Toolsets

► Adhered to best practises:▪ Used only LOCAL Custom Properties▪ Made internal properties private▪ Be aware of limited error checking

Automatic Tag Linking

► Automatic Tag Linking is one of the most powerful features of Archestra:▪ Standardised on tag based A-B ControlLogix

PLCs▪ Implemented standard blocks in PLC▪ Rigidly enforced our chosen tag naming

convention▪ Linked to PLC tags via scripting

Automatic Tag Linking

Instantiating Objects

► The fastest method of creating multiple instances - use the CSV Export and Import Object functionality

► Create, then Export an example instance, copy/paste the new instances and Import

► Only keep the necessary columns

► Use Excel 2007 or later

Zapping Bugs

► We were one of the first companies to start a System Platform 3.0 project:▪ ASSMANG Cato Ridge – Started

development on Beta version (July 2007)▪ ASSMANG Khumani - Started development

on Gold version (Aug 2007)► Identified NUMEROUS bugs► Progressed through Patch 1, Patch 2,

Patch 3, SP1, numerous Hot-fixes and finally SP2!

More Bugs

▪ Copy Paste chaos!▪ Archestra Graphics: >10min to open!▪ Managed Intouch Application: >1hr to open!▪ Duplicate ID’s

Denial!

► During the first 4-months of the project:▪ We assumed that the issues were being addressed▪ We did not realize that we were the first to

experience the problems▪ We blamed most of it on finger trouble and network

problems▪ We became very creative at finding workarounds▪ We reported nothing!

Zapping the Bugs!

► From Feb 2008 to Sept 2008:▪ We started logging ALL issues - we logged more than

39 issues▪ The severity of the issues ranged from terminal to minor

irritation▪ More than 25 Hot fixes, Patches, Service Packs and

Utilities have since been issued by Wonderware to address these problems

▪ SP1 – We were the 1st and only to install SP1▪ Support staff from Wonderware EMEA and

Wonderware SA flew out to site on numerous occasions to investigate the issues

▪ We arranged weekly WebEx teleconferences with Wonderware EMEA and Wonderware USA

Reporting Procedure

► Reporting chain: SI/Client -> Wonderware SA -> Wonderware EMEA -> Wonderware USA

► Phone Wonderware support (0861 WONDER) to determine if this is a known issue

► Send supporting e-mails to [email protected] and not to individuals

► To fast-track the problem, one has to provide Wonderware with a RECIPE to replicate the problem

mailto:[email protected]

Reporting Procedure

► Recipe:▪ An in-depth description of the problem▪ Software versions - Wonderware and Microsoft▪ Wonderware SMC log-files (.aaLGX) from the View

Node, Galaxy and AOS▪ Microsoft log-files (.evt) from the Microsoft Event

Viewer – Application, Security an System▪ Screen-captures (.jpg) illustrating the problem▪ Galaxy Backup (.cab) or Object Export (.aaPKG)

► Wonderware SA can only escalate the problem to Wonderware EMEA once they have also been able to replicate the problem

Reporting Procedure

► KEEP YOUR COOL – We are all in the same boat!► Before a Hot-fix can be issued to an SI or End-User,

a signed Hot-fix agreement has to be signed

The End Result

► After SP2:▪ Archestra Graphics: <10sec to open▪ Managed Intouch Application: <30sec to open▪ All mayor bugs have been zapped!▪ The only outstanding issues are nice-to-haves, all

of which I still want!

Agenda






Benefits

► Initial development time took longer than expected due to:▪ The bugs in the software▪ The P&ID’s were never frozen▪ The PLC developers made drastic changes

in their code until very late in the project▪ Inexperience

Benefits

► However, for phase 2 of the project, the picture is completely different:▪ Development time will be drastically

reduced▪ FAT Testing and Commission time will be

minimal▪ No scalability constraints

Agenda






Considerations

► The Galaxy Repository is a critical component. Have an off-line system available for tests and as backup

► Communicate with Wonderware – bugs don’t fix themselves!

► TRAINING, TRAINING, TRAINING! Higher skills level required for Archestra than for Intouch

► Do your Engineering upfront, BEFORE you begin with your Archestra development

Considerations

► Manage Archestra biggest strength/weakness – it’s flexibility

► Draw up a System Checklist for setting up all computers in the system

► MAKE REGULAR OFF-SITE BACKUPS

► Be aware of the risks when developing in a new version of any software

► Make use of VPN Dial-In and Microsoft Remote Desktop

Agenda






Summary

► Communication and Teamwork are critical

► All software bugs can be overcome!► We have a happy client► The Archestra system works brilliantly► We are looking forward to phase-2 of

the project!
