AI Block Parameter
Attribute Definitions
The following table describes the parameters that are available in the analog
input function block. Each line item in the table defines the element and
specifies the requirements for each element.

Parameter Description
Profibus PA Specific Block
Header
16 BLOCK_OBJECT This object contains the characteristics of the
blocks.
17 ST_REV The modification of at least one static parameter in
a block has to be incremented by the according
ST_REV at least by one.
18 TAG_DESC Every block can be assigned a textual TAG
description. The TAG_DESC must be unambiguous
and unique in the fieldbus system.
19 STRATEGY Grouping of Function Block. The STRATEGY field
can be used to group blocks.
20 ALERT_KEY This parameter contains the identification number
of the plant unit. It helps to
identify the location (plant unit) of an event.
21 TARGET_MODE The TARGET_MODE parameter contains desired
mode normally set by a control application or an
operator. The modes are valid alternatively only,
i.e. only one mode can be set at one time. A write
access to this parameter with more then one mode
is out of the range of the parameter and have to be
refused.
22 MODE_BLK This parameter contains the current mode, the
permitted and normal mode of the block.
23 ALARM_SUM This parameter contains the current states of the
block alarms.
24 BATCH This parameter is intended to be used in Batch
applications. Not implemented in 8732E device.
25 RESERVED by PNO
26 OUT The Function Block parameter OUT contains the
current measurement value in a vendor specific or
configuration adjusted engineering unit and the
belonging state in AUTO MODE. The Function
Block parameter OUT contains the value and status
set by an operator in MAN MODE.
27 PV_SCALE Conversion of the Process Variable into percent
using the high and low scale values. The
engineering unit of PV_SCALE high and low scale
values are directly.
28 OUT_SCALE Related to the PV_UNIT of the configured
Transducer Block (configured via Channel
parameter). The PV_SCALE high and low scale
values follow the mapped to last 16 characters of
DEVICE_ID_STRING parameter in Mfg. Block.
29 LIN_TYPE Type of linearization. The 8732E only supports “No
linearization”.
30 CHANNEL Reference to the active Transducer Block which
provides the measurement value
to the Function Block.
31 RESERVED
32 PV_FTIME Filter time of the Process Variable.
