FOUNDATION Fieldbus Integration
ADM Status (MDI Function Blocks)
Add 1 or 2 DGW-FF multiple digital input (MDI) function blocks to your schedule.
If you use 1 ... 8 ADMs, 1 MDI is sufficient. If you use 9 ... 16 ADMs, 2 MDI function blocks are
required.
Channels:
• Binary Status ADM x-y (Channel 2, 3): Value is 0 (no error) or 1 (other status).
"1" means any segment or system on the related ADM has a status other than "no error",
"excellent", "good" or "segment disabled".
• Enum Status ADM x-y (Channel 12, 13): Worst status for all systems and segments of
ADM_TBs in AUTO mode. The encoding is the same as for the enum status of all ADMs
listed above.
Channel 2 and 12 correspond to ADM_TB 1 ... 8, channel 3 and 13 correspond to
ADM_TB 9 ... 16.
Field Diagnostic Value (DI Function Block)
Add DGW-FF digital input (DI) function block to your schedule.
Channel:
Field Diagnostics (Channel 201): The current worst active status of field diagnostics is trans-
ferred as an enumeration using a DI. The data the field diagnostic status is built from can be
configured at the resource block and may also include other diagnosis information in addition
to the ADM information. The value uses the following encoding:
Value
00h
30h
01h
02h
20h
6.3.2 Field Diagnostics
The FF-H1 field device built in the DGW-FF supports field diagnostics according to FF-912.
This also includes alarm information from the ADMs. For more information, see chapter 8.4.
6.3.3 Transducer Block Alarms
The ADM transducer blocks support block alarms. If the status of any segment shows an error,
i.e., if the XD status is not "Good", "Excellent" or "No error", a block alarm with a BLOCK_ERR
value of the other is activated.
6.4 Operation with Device Descriptions (DD)
The DGW-FF supports the following Device Description Languages (DDL): DD4, and EDDL
(Electronic Device Description Language, also DD5). DD4 only supports a reduced set of fea-
tures compared to EDDL. Therefore, it is recommended to use EDDL if your process control
system (PCS) supports this option. The differences are explained in the following chapters. For
more information on all parameters supported by the FF-H1 field device, see chapter 8.2.
EDDL (DD5) contains 2 sets of menus for the use cases configuration and diagnostics. The
configuration menu contains all parameters necessary to configure the maintenance limits. The
diagnostics menu provides an overview of the actual measured values and diagnosis informa-
tion.
