  2. Enterprise Data Layers Company Management Information Company Management Data Presentation Level 5 Company Production Assignment Scheduling Supervision Company Production Scheduling Assignment IT Security Policies and Practices (ISO 17799) Production Scheduling & Operational Management Operational & Production Supervision Level 4 Common technologies, policies and practices Purdue reference Model Levels Inter-Area Coordination Supervisor’s Console Level 3 Supervisory Control Supervisor’s Console Level 2 Ethernet Mfg Security Policies and Practices (ISA 99) Direct Digital Control Operator’s Console Level 1 HSE Process Safety (ISA 84, IEC 61508, IEC 61511) Controllers H1 Process Safety Critical

  3. Resource Block • Hardware information • Status information • Transducer Block • Isolates function blocks from local I/O functions required to read sensor • Stores calibration information • Function Blocks • Provide control system behavior • 10 standard function blocks • 19 additional ones will be available Function Blocks Transducer Block Physical Sensor or Actuator Fieldbus Device Structure Fieldbus Resource Block

  4. Resource Block (RB) • Contains data that is specific to the hardware that is associated with a device • no links • no data processing • each device must have a resource block • ON / OFF switch for device • All configurations • MODE_BLK: Auto

  5. Transducer Block (XD) • Manufacturer-specific • Each device has a different XD • Sensor information • Calibration • Status • All configurations • MODE_BLK: Auto • Device-specific • TERMINAL_NUMBER (IF and FI devices) • SENSOR_TRANSDUCER_NUMBER (dual temp. dev.)

  6. Function Blocks • Another key feature • enables control strategy implementation • allows function blocks from different manufacturersto pass information • Standard function blocks: • Discrete Input • Discrete Output • Analog Input • Analog Output • PID/PI/I Controller • PD/P Controller • Control Selector • Manual Loader • Bias / Gain Station • Ratio Station

  7. Function Blocks • Pulse Input • Complex Analog Output • Complex Discrete Output • Step Output PID • Device Control • Deadtime • Integrator • Analog Alarm • Analog Human Interface Advanced function blocks: • Setpoint Ramp Generator • Input Selector • Signal Characterizer • Lead Lag Controller • Signal Splitter • Arithmetic • Timer • Digital Alarm • Digital Human Interface

  8. Algorithms Outputs Inputs Example: PID Alarm Subsystem Mode Structure (Manual, Auto, etc...) Event Subsystem Function Block Model

  9. Flexible Function Block New Block Subclass - Flexible • Flexible (MIO) - Part 4 • Multiple Analog Input - 8 Channels • Multiple Analog Output - 8 Channels • Multiple Discrete Input - 8 Channels • Multiple Discrete Output - 8 Channels • Flexible (IEC 61131-3) - Part 5 • Application-specific Blocks

  10. Flexible Function Block • FULLY User Configurable • Use IEC languages to define: • Block calculations • Data Manipulation • Outputs can be ANY of the Function Block types defined by the Foundation including Multiple Inputs

  11. Flexible Function Block - Hardware • Linking Device most prevalent • Interface between H1 and HSE • HSE based output • Classes • Linking • Field • Only Linking Class available at present

  12. High Speed Ethernet (HSE) • Based on Ethernet • Supports all types of physical media • Fiber (IS) • Copper • Coax • H1 consumes 1% of available bandwidth • “Comingle” with other Ethernet based communications if desired • Web based, etc.

  13. Enterprise Data Layers Company Management Information Company Management Data Presentation Level 5 Company Production Assignment Scheduling Supervision Company Production Scheduling Assignment IT Security Policies and Practices (ISO 17799) Production Scheduling & Operational Management Operational & Production Supervision Level 4 Common technologies, policies and practices Purdue reference Model Levels Inter-Area Coordination Supervisor’s Console Level 3 Supervisory Control Supervisor’s Console Level 2 Ethernet Mfg Security Policies and Practices (ISA 99) Direct Digital Control Operator’s Console Level 1 HSE Process Safety (ISA 84, IEC 61508, IEC 61511) Controllers H1 Process Safety Critical

  14. Data Transfer beyond Field Level • Data Objects • Consistent definition from field to ERP • Develop “data dictionary” • ISA-76 Working Group • Formed at AD 2005 • Develop path forward for project plan approval in October

  15. Next Steps • Consistent “dictionary” • Compatible with existing efforts by other organizations • ISA • Mimosa • Namur • Others? • Object based • Parent-child relationships • Apply throughout system

  16. Next Steps • Call for volunteers • Contribute materials for • Analyser types • Sample system variables • S.A.M.
