3. Fieldbus Device Structure
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
Fieldbus
Resource
Block
Function
Blocks
Transducer
Block
Physical Sensor or
Actuator

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 Standard function blocks:
enables control strategy implementation
allows function blocks from different manufacturers to 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 Advanced function blocks: Pulse Input
Complex Analog Output
Complex Discrete Output
Step Output PID
Device Control
Deadtime
Integrator
Analog Alarm
Analog Human Interface
Setpoint Ramp Generator
Input Selector
Signal Characterizer
Lead Lag Controller
Signal Splitter
Arithmetic
Timer
Digital Alarm
Digital Human Interface

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

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 ) - 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.

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” Apply throughout system
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.
