The required reference graphs are automati-
cally plotted after initialization and saved in
the positioner if EXPERT
+ is activated.
The optional diagnostic functions provided
by EXPERT
+ can be selected when ordering
the positioner. Additionally, it is possible to
activate EXPERT
+
at a later point in time in
an existing positioner. For this purpose, an
activation code can be ordered, requiring
the serial number of the positioner to be
specified.
6.3 Classification of the status
alarms and the condensed
status
Note: The following description only applies
to positioners configured corresponding to
the Profile 3.01 with the extension “Con-
densed status and diagnostic messages”
(adjustable in COND_STATUS_ DIAG pa-
rameter of the Physical Block).
The alarms are classified in the positioner,
i.e. when an alarm is issued, it is assigned a
status. The classification of the states can be
changed.
To provide a better overview, the positioner
state is summarized in a condensed state.
This condensed state is made up from a
summary of all classified status alarms.
If an event is classified as “No message”,
this event has no influence on the condensed
status. If the classification “No message” is
assigned for a diagnostic alarm, this alarm
is not included in the diagnostic parameter.
To be able to read all diagnostic alarms re-
gardless of which classification they have
been assigned to, these are entered in
DIAGNOSIS_EXT_1_RAW and
DIAGNOSIS_EXT_2_RAW parameters.
The following states can be selected (refer to
Fig. 25):
4
Maintenance alarm
The positioner cannot perform its control
task due to a functional fault in the
device or in one of its peripherals or an
initialization has not yet been
successfully completed.
4
Maintenance required
The positioner still performs its control
task (with restrictions). A maintenance
demand or above average wear has
been determined. The wear tolerance will
soon be exhausted or is reducing at a
faster rate than expected. Maintenance
is necessary in the medium term.
4
Maintenance demanded
The positioner still performs its control
task (with restrictions). A maintenance
demand or above average wear has
been determined. The wear tolerance will
soon be exhausted or is reducing at a
faster rate than expected. Maintenance
is necessary in the short term.
4
Process related fault/Out of
specification
The current process conditions do not
allow a valid calculation of values.
4
Function check
Test or calibration procedures are being
performed. The positioner is temporarily
unable to perform its control task until
this procedure is completed.
