The addresses indicated in “Table 119” 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 120”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.

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.
