Advanced Diagnostics
FOUNDATION Fieldbus Integration
6 FOUNDATION Fieldbus Integration
The FOUNDATION Fieldbus integration is based on an FF-H1 field device inside the diagnostic
gateway. These devices map the data of up to 16 HD2-DM-A modules to FOUNDATION Field-
bus data structure.
Both the measurement data and the expert system evaluations of the data are available inside
the data structures of transducer blocks. Advanced diagnostic modules (ADM) alarms are sent
to a process control system (PCS) using block alarms, field diagnostic alarms, or scheduled
function block data.
Beside the DD for integration into the PCS, also a DTM is available providing a more comfort-
able access to the advanced physical layer diagnostic functionality and additional functions.
The FF-H1 field device supports up to 16 HD2-DM-A ADMs, with each providing 4 segments.
This results in 64 segments supported by one diagnostic gateway in FF-H1 mode.
Each segment supports up to 18 FF-H1 field devices including the host(s).

6.1 FF Device Structure
The device consists of the following function blocks:
• 1 resource block
• 16 ADM_TB transducer blocks: Each block corresponds to 1 ADM with 4 segments
• 1 IO_TB transducer blocks: The I/O functionality of the device is described in a separate
chapter. See chapter 7
• 4 multiple digital input (MDI) function blocks
• 1 digital input (DI) function block
• 1 multiple analog input (MAI) function block only usable for IO_TB
• 1 multiple digital output (MDO) function block only usable for IO_TB
The following image shows a simplified device structure that only takes ADM_TB transducer
blocks and the associated function blocks into account. For more information on the IO_TB and
its corresponding function blocks, see chapter 7.
