Mode
Information on this block such as Block Tag, DD Revision, Execution
Time etc.
The revision level of the static data associated with the function block.
The revision value will be incremented each time a static parameter
value in the block is changed.
The user description of the intended application of the block.
The strategy field can be used to identify grouping of blocks.
This data is not checked or processed by the block.
The identification number of the plant unit. This information may be
used in the host for sorting alarms, etc.

Set the Target of block mode (MODE_BLK) to Auto or O/S according
to the Write Mode of the parameter to be set or changed.
The mode parameter is a structured parameter composed of the
actual mode, the normal mode and the permitted mode.
Actual: Indicates the current operating condition.
Permit: Indicates the operating condition that the block is allowed
to take.
Normal: Indicates the operating condition that the block will usually
take.

This parameter is intended to be used in Batch applications in line
with IEC 61512. Auto BATCH_ID 0
26 OUT
(DS-33) This parameter contains the current measurement value from
Transducer Block or configuration adjusted engineering unit and the
belonging state in AUTO MODE.
OUT contains the value and status set by an operator in MAN MODE. Man Value 0
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
direct related to the PRIMARY_VALUE_UNIT of the configured
Transducer Block (configured via Channel parameter).
The PV_SCALE high and low scale values follow the changes of the
PRIMARY_VALUE_UNIT of the related Transducer Block
automatically, i.e. a change of the Transducer Block PRIMARY_
VALUE_Unit causes no bump at OUT from AI. O/S 0.00001 to 32000

SCALE
(DS-68) Scale of the Process Variable.
This parameter contains the values of the lower limit and upper limit

Variable and the number of digits on the right hand side of the
decimal point. O/S EU at 100%
