Benefits:

  • Captures requirements and automatically generates documentation.
  • Adherence to company procedures and safety standards is inherent through use.
  • Minimise systematic errors, lower risk, achieve time and cost milestones.
  • Formal, robust approach to knowledge capture of engineers, operators and plant data.
  • Repeatability of consistent, accurate, compliant design.
  • Efficient use of valuable resource.
  • Accurate means for reverse engineering and upgrade of existing control and safety systems.

Requirements Capture
TriDefine WhiteBoards allow the user to specify and develop the overall project requirements, and cross-reference the latest priority information.
Benefits:

  • Easy to understand and configure due to graphical 'Drag & Drop' format.
  • Efficient capture of information encourages team participation.
  • Team participation reflected in improved results from web conferencing.
  • Knowledge capture helps climb the learning curve.

Functional Safety Management (FSM)
The FSM layer is a dynamic WhiteBoard.  It allows the user to define the safety and project lifecycle phases, assign resource, plan activities, identify verification and functional assessment milestones and configure documentation.
Benefits:

  • FSM lifecycle and activities are clearly evident and understood by all team members.
  • FSM configuration reduces workload and helps achieve safety targets.
  • Compliance to FSM standards becomes straightforward and easy to adopt.
  • Remote monitoring allows audit and assessment to be performed easily.
  • Access control enables the assignment of tasks to competent personnel only.
  • Automatic report generation means that a current status report is always available.

Powerful Document Generation
Project documents, based on typical company templates, are defined, configured and automatically generated within TriDefine.
Benefits:

  • 'Drag & Drop' enables the rapid configuration of typical project documentation.
  • A change in any piece of project data is reflected automatically in the documentation saving substantial hours in document management.
  • Instant document generation reveals significant man hour savings.
  • Data tracking allows automatic production of 'change pack' documentation.

Plant Simulation Models
Plant simulation models are developed to provide low fidelity process models and animated visual representation of process information and operator panels.
Benefits:

  • Running process model enables verification of requirements, and leads to a high level of confidence in the final design.
  • Playback feature enables further review and refinement.
  • 'What if' scenarios and degraded modes of operation can be explored to further increase robustness of the design.
  • Models execute within TriDefine and TriViewer.
  • Valuable training aid for plant operators and technicians, increasing domain knowledge.

Detailed Application Engineering - State Analysis (SA) Module
State Analysis Modules allows the user to develop state chart style models to describe the detailed behaviour of an application.  When utilised as a method of design, SA Modules provide a robust means of transforming customer requirements to application code.
Benefits:

  • Intuitive graphical environment promotes a robust safety design.
  • Instant visual appreciation of process state helps develop understanding.
  • Greater understanding of plant or trip signal inhibits.
  • Design, partial and full emulation modes allow for verification of design and validation to requirements, lowering risk.
  • Automatic generation of application code as IEC61131-3 FB diagrams.
  • Rapid prototyping of customer requirements enables a shorter design phase.

Detailed Application Engineering - Cause & Effect (CE) Module
The Cause & Effect module allows the user to develop a CE matrix to describe the functional relationship between input variable and output variable.
Benefits:

  • Provides a conventional approach preferred by many engineers.
  • Immediate emulation enables verification of design and validation to SIS requirements, lowering risk.
  • Export to MS Excel (.xls) format, in conventional style and format.
  • Automatic generation of application code as IEC61131-3 FB diagrams.
  • Rapid prototyping of customer requirements enables a shorter design phase.

Detailed Application Engineering - Logic Editor
The Logic Editor is an IEC61131 FBD editor used for graphically building logic diagrams.  It is at the heart of many of the TriDefine components, including the Function Block editor, Typicals editor, SA and CE modules.
Benefits:

  • Assign requirements, and build, test and document in minutes using simple, intuitive controls.
  • Re-use or import standard libraries for rapid replication, and standardisation of design.
  • Automatic layout options promote rapid development.
  • Automatic data type validation improves quality and reduces errors.
  • Immediate emulation enables verification of design and validation to requirements, lowering risk.

Detailed Application Engineering - Typicals Editor
The Typicals Logic Editor uses the Logic editor to define logic templates.  Generally used for IO and device processing logic, instances of the templates are incorporated into logic models allowing interfacing to the SA and CE modules.
Benefits:

  • Powerful configuration engine helps apply formal conventions to automatically produce a consistent tag database.
  • Complex tag name conventions are simple to apply.
  • Re-use or import standard libraries for rapid replication, and standardisation of design.
  • Immediate emulation enables verification of design and validation to requirements, lowering risk.
  • Group Typicals support advanced grouping and linking.

Integrated Test Framework - Viewers
TriDefine Viewers allow the user to combine simulation models and module components into a single framework for test and review.  The simulation models and application logic run together providing an overall representation of the system.
Benefits:

  • Manual and ad-hoc testing of functional logic.
  • Visual representation promotes easy understanding of the application and user interaction.
  • Full history recording, event recording and playback enables further review and refinement.
  • Snapshot input conditions to move directly to key process states for review, test or training exercise.
  • Export for use with TriViewer and TriVision enables re-use for remote review and plant monitoring.

Integrated Test Framework - Test Case Editor
The Test Case editor allows the user to define functional test cases.  The test cases are transformed into test scripts which can be executed in any of TriDefine’s emulation environments or supported target PLC.
Benefits:

  • Automatic generation of test scripts provides greater test coverage.
  • Execution of Test Cases against TriDefine emulation model at 10X real time.
  • Automatic recording of response data for review and validation to requirements.
  • Support for initialisation settings from Viewer snapshots
  • Integrated environment for development of formal test specifications, reveals significant man hour savings.
  • Advanced support for customisable user defined test functions.
  • Increased coverage provided by repeatable, functional Test Cases means that a target of error-free factory acceptance test becomes achievable.
