9.12.3 Transducer Blocks
FOUNDATION Fieldbus Transducer Blocks standard parameters
Transducer Block, FOUNDATION Fieldbus standard parameters (all Transducer Blocks)
Parameter Description
Static Revision/ST_REV
Display
Index: 1
Data type: unsigned16
Access: read only
Displays the counter for static parameters of the Transducer Block.
The counter is incremented by one with each change of a static parameter of the
corresponding Transducer Block. The counter counts up to 65535 and then starts
again at zero.
Tag Description/
TAG_DESC
Entry
Index: 2
Data type: octet string
Access: wr for Auto,
OOS
Enter a description for the related block or the measuring point e.g. TAG number
(max. 32 alphanumeric characters).
Factory setting:
Empty field
Strategy/STRATEGY
Entry
Index: 3
Data type: unsigned16
Access: wr for Auto,
OOS
Enter user-specific value for grouping and thus faster evaluation of the blocks.
Grouping takes place by entering the same numerical value for the Strategy/
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/ALERT_KEY
Entry
Index: 4
Data type: unsigned8
Access: wr for Auto,
OOS
Enter the identification number for the measuring device or for each individual block.
The control level uses this identification number to sort alarm and event messages and
initiate other processing steps.
Input range:
1...255
Factory setting:
0
Block Mode/
MODE_BLK
Selection, display
Index: 5
Data type: DS-69
Access: wr for Auto,
OOS
The Block Mode/MODE_BLK parameter is a structured parameter consisting of four
elements. The Transducer Blocks support the "Auto" (automatic) 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.
Measured values or information can be forwarded to an Analog Input Block via the
Pressure, Service and DP_Flow Transducer Block. If the Pressure Transducer Block is
set to the OOS block mode, the Primary Value and Secondary Value continue to be
updated but the status of the downstream Analog Input Block changes to BAD.
Block Error/
BLOCK_ERR
Display
Index: 6
Data type: bit string
Access: read only
Displays the warning messages and error messages of the software and hardware of
the Transducer Block in question. In addition, this parameter triggers an alarm. If two
or more messages occur simultaneously, the message with the highest priority is
shown on the display.
For the Pressure and Totalizer Block, see possible messages, these Operating
Instructions, Section 11.1 "Messages". The Display and Diagnostic Block do not display
any warnings or error messages.
