The addresses indicated in “Table 121” can be used as a path data for the attribute Produced Connection Path of
an I/O connection.
The attributes described in more detail in the following “Table 122”can be transferred as input process data via this
I/O connection.
Nevertheless, by using this address data, the attributes combined in the assemblies can also be accessed acycli-
cally via Explicit Messages.
Name Description of the input data attributes Attribute Address Class,
Instance, Attribute;
Data type, Length
POS
Actual position
Actual value of positioner as ‰. Value range 0 – 1000. However,
values <0 or >1000 also possible if e.g. Autotune has not run
through correctly.
111, 1, 59;
INT, 2 byte
CMD
Nominal position
Set-point value of positioner as ‰. Value range 0 – 1000.
111, 1, 58;
UINT, 2 byte
PV *
Process actual value (process value)
Actual value of process controller in physical unit (as set in the
menu P.CONTROL → SETUP → PV-INPUT or PV-SCALE), max.
value range -999 – 9999, depending on internal scaling.
120, 1, 3;
INT, 2 byte
SP *
Process set-point value
Set-point value of process controller in physical unit (as set in the
menu P.CONTROL → SETUP → SP-INPUT or SP-SCALE), max.
value range -999 – 9999, depending on internal scaling.
120, 1, 2;
INT, 2 byte
ERR
Error
Indicates the number of the process value (output) which was not
written. The value is retained until it is deleted with “1” by acyclically
writing the “Error” attribute (access via Explicit Message – Set
Attribute Single).
