6.3 Transducer Blocks
6.3.1 FOUNDATION Fieldbus standard parameters Transducer
Blocks
Transducer Block, FOUNDATION Fieldbus standard parameters (all Transducer Blocks)
Parameter Description
ST_REV
Display
Index: 1
Data type: Usigned16
Access: Read only
Displays the counter for the static parameters of the Transducer Block
This counter is increased by one with each change to a static parameter of the Transducer
Block in question. The counter counts to 65535 and then starts again at zero.
TAG_DESC
Entry
Index: 2
Data type: Octet String
Access: Auto, OOS
Enter a description for the associated block or the measuring point e.g. TAG number
(max. 32 alphanumeric characters).
Factory setting:
Empty field
STRATEGY
Entry
Index: 3
Data type: Unsigned16
Access: Auto, OOS
Enter a user-specific value for grouping and thus faster evaluation of the blocks.
Grouping takes place by entering the same numeric value for the STRATEGY parameter of
the block in question. These data are neither checked nor processed by the Transducer
Blocks.
Input range:
0...65535
Factory setting:
0
ALERT_KEY
Entry
Index: 4
Data type: Unsigned8
Access: Auto, OOS
Enter the identification number for the device or for each individual block.
The host system uses this identification number to sort alarm and event messages and initiate
further processing.
Input range:
1...255
Factory setting:
0
MODE_BLK
Display, Selection
Index: 5
Data type: DS-69
Access: Auto, OOS
The MODE_BLK parameter is a structured parameter consisting of four elements.
The Transducer Blocks support the "Auto" (automatic mode) and OOS
(out of service) modes.
TARGET
• Change the block mode.
ACTUAL
• Displays the current block mode.
PERMITTED
• Displays the modes supported by the block.
NORMAL
• Displays the block mode during standard operation.
!
Note!
Measured values or information can be forwarded to an Analog Input Block by means of the
Pressure, Service and Totalizer Transducer Block. If the Pressure Transducer Block is set to
the OOS block mode, for example, the primary and secondary value continue to be updated
but the status of the downstream Analog Input Block changes to BAD.
BLOCK_ERR
Display
Index: 6
Data type: Bit String
Access: Read only
Displays the warning and error messages of the software and hardware of the Transducer
Block in question. This parameter also triggers an alarm. If two or more messages occur at the
same time, the message with the highest priority is the one shown on the display.
For the Pressure, Service and Totalizer Block, see possible messages in these Operating
Instructions, Section 11.1 "Messages". The Display and Diagnostic Blocks do not display any
warning or error messages.
