Definition Message
Type
This object contains the RECORD
characteristics of the block
A block has static block SIMPLE
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.
Every block can be assigned a SIMPLE
textual TAG description. The
TAG_DESC must be
unambiguous and unique in the
field bus system.
Grouping of function block. SIMPLE
The STRATEGY field can be
used to group blocks.
This parameter contains the SIMPLE
identification number of the
plant unit.
This parameter contains SIMPLE
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.
This parameter contains the RECORD
current mode and the permitted
and normal mode of the block.
This parameter contains the RECORD
current states of the block
alarms.
This parameter is intended to RECORD
be used in Batch applications
in line with IEC 61512
Part1. Only Function Blocks
carry this parameter. There is
no algorithm necessary
Within a Function Block.
The Function Block parameter RECORD
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.
Conversion of the Process ARRAY
Variable into percent using the
high and low scale
values.
Scale of the Process Variable. RECORD
Type linearizationion. SIMPLE
Reference to the active SIMPLE
Transducer Block which
provides the measurement
value
to the Function Block.
Filter time of the Process SIMPLE
Variable.
