16 BLOCK_OBJECT This object contains the
characteristics of the block

17 ST_REV A block has static block
parameters that are not
changed by the process.
Values are assigned to this
parameter during the
configuration of optimization.
The value of ST_REV
increases by 1 after every
change of a static block
parameter.
SIMPLE Unsigned16 2 N 0 R NA NA
18 TAG_DESC Every block can be assigned
a textual TAG description.
The TAG_DESC must be
unambiguous and unique in
the field bus system.

32 S ‘ ’ R/W NA NA
19 STRATEGY Grouping of function block.
The STRATEGY field can be
used to group blocks.
SIMPLE Unsigned16 2 S 0 R/W NA NA
20 ALERT_KEY This parameter contains the
identification number of the
plant unit.
SIMPLE Unsigned8 1 S 0 R/W NA NA
21 TARGET_MODE This parameter contains
desired mode normally set by
a control application of 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 than
one mode is out of the range
of the parameter and has to
be rejected.

R-2287
22 MODE_BLK This parameter contains the
current mode and the
permitted and normal mode
of the block.
RECORD DS-37 3 D --- R NA R-2288
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
in line with IEC 61512 Part 1.
Only Function Blocks carry
this parameter. There is no
algorithm necessary within a
Function Block.
