(How) Do you? Ensure Automation Systems meet End User needs Must haves, wishes etc Manage User approvals Manage automation projects Design before programming! Track progress Manage changes Ensure Specifications are accurate Define the Modularisation of a system S88 etc

ControlDraw Introduction Software for Specifying and Designing Automation systems Hierarchical and Graphical Object models Discrete, S88 batch and Continuous control High definition Specifications for the entire Life Cycle Improves User understanding Improves Project Management Reduces errors Accelerates development

ControlDraw Description Uses a Hierarchical and Graphical object modelling approach Appropriate Diagrams for all modules Includes State oriented objects and methods Includes simulation, verification and more A ControlDraw model is database Tables automatically generated from the contents of diagrams Advanced data population

Advantage of graphical specifications (Good) Diagrams are much less ambiguous than text User understanding is improved New Users may need a few hours of training Then User approval is more meaningful And traceable

Graphical Objects Diagrams show the Objects in a process Diagram Symbols can be much more than pictorial, they can be S88 Objects corresponding to the S88 entities Recipe Procedures, Units Equipment modules, Control Modules etc

Hierarchical Objects can contain objects, by linking an object to a Child Diagram This is recursive so allowing hierarchies that match the S88 Physical and Procedural Models

Object properties Class Extended S88 types Eg Unit, EM, CM Data structure for instance data Data Symbols can contain data This can cascade down the hierarchy (inheritance)

Object Instances ControlDraw scans a model to create records for all object instances Each Class has configurable database tables These can match PLC and DCS structures

Diagrams SFC – Sequential Function Charts for Phases and Operation (Equipment Procedural Entities)

Diagrams PFC –Procedure Function Charts For Recipe Procedures, Recipe Unit Procedures, Recipe Operations

Diagrams SAMA, Logic For Control Modules

States and state matrices All objects in a model can have States These can be related to each other. An SFC action can set the state of an object A State Matrix can be built relating for example Equipment Module to Control Module states

Simulation Many Diagrams types can be put into simulation mode Test Control Strategies

S88 Procedure to Equipment Linking The Recipes can be linked to the equipment by referencing Recipe Procedural elements to Equipment Procedural elements

Build libraries of modules. Diagrams can be re-used in multiple models Reference model contains the shared diagrams Reference model also defines the classes Diagrams can be made polymorphic so the one diagram can cover a number of similar modules

Version Controls Everything in a model has a version number: Diagrams Classes Matrices Data Compare facilities provide details on all changes

Comparison with P&ID CAD systems Products like SmartPlant and Comos have some capability But only a small portion of the scope of ControlDraw models

What can a Project manager get out of ControlDraw? High quality System Independent Specifications Provide traceable estimates Can be for implementation in-house or externally by a third party With design control retained even when using third party Proposal Models Estimates Initial client approval Project Control Continual Scope Measurement Change Tracking Built in features such as Diagram Review Status help

What expertise must my engineers have? Not all need the same level Some might just do the simpler things P&ID based tasks for example to take a P&ID and make a ControlDraw diagram Experts can then develop the model It is possible to quickly make major changes and even restructure models without losing the value of the work already done CD includes Model Review and Advisor functions To check for consistent models and much more

The ControlDraw Reviewer View, navigate, and print the contents of a ControlDraw model Make comments on the diagrams and matrices Make compare reports that show all changes between model versions Extract all data from models Can be used for online documentation

Opportunities Get in at the beginning of projects Develop System independent models Focussed on end user requirements in the recession Clients may scale back or postpone projects But often they keep a small front end going

Concluding The more you do with ControlDraw, the more you can get out of it Examine all the documents you produce outside CD Can they be done With CD? If not then maybe improvements to ControlDraw can be made
