Fieldbus Version Considerations
The models 265 / 267 / 269 FOUNDATION
TM
Fieldbus version differs by the traditional
4 … 20 mA version only in the secondary electronic and in the Terminal block. The transducer
with its own primary electronic has to be considered the common part of all the different
Transmitter versions (HART, PROFIBUS and FF). This feature offers the possibility to replace
on the same transmitters different electronics with the plug and play capability.
The models 265 / 267 / 269 FOUNDATION Fieldbus Revision 2 implements and is compliant to
the communication Protocol FOUNDATION
TM
Fieldbus specification version 1.5.
The models 265 / 267 / 269 FF Revision 2 is registered as a Link Master Device. When the
models 265 / 267 / 269 FF is properly configured as back-up LAS, if the current LAS running in
the controller fails, it enables its own LAS functionality with the task to maintain alive the
Fieldbus operations.
The models 265 FF Revision 2 includes:
- 1 Standard Resource Block
- 2 Standard Analog Input Function Blocks
- 1 Standard PID Function Block
- 1 Custom Pressure with Calibration Transducer Block
The models 267 / 269 FF Revision 2 includes:
- 1 Standard Resource Block
- 3 Standard Analog Input Function Blocks
- 1 Standard PID Function Block
- 1 Custom Pressure with Calibration Transducer Block
- 1 Temperature Transducer Block
- 1 Multi Variable Function Block
Here is a summary of the FF functionality implemented in the models 265 / 267 / 269 FF:
- Client / Server VCR
This communication type is used for the operator messages like read / write of configurations
or maintenance data. This is a not scheduled message but executed when the operator
requires it.
- Publisher / subscriber VCR
This communication type is used for Process Control purpose. These are the scheduled and
cyclic exchange of data.
- Report / Distribution VCR
This communication type is used when the slave device has to advise the operator consoles
about the occurrence of alarms (Event Notification) or for Trend report.
