1 About this manual
1.1 Target readers
This user's guide is written for the users of the plant and for
service engineers. It is assumed that the users of the manual
will have the necessary understanding of the system and
plant.
1.2 Content
The descriptions in this manual cover the commissioning,
basic configuration and use of the PXM10 operator unit.
As there may be significant differences between one plant
and another, and between one object and another, it follows
that it is not possible to provide a description which is
generally applicable to every individual case. The question of
exactly which objects are integrated with which values in a
plant, is determined in the engineering phase according to
the individual needs of the plant operator.
Important The descriptions in this manual are intended as examples
only, and are designed to clarify the basic operating
principles of the PXM10 operator unit.

1.3 Printing conventions
1.3.1 Text in display panel
Bold text is used to denote the exact text which appears in
the display, e.g. Main menu or Settings.
1.3.2 Labeling of the push-dial and buttons
The main operator control element, the "push-dial", is not
named on the housing.
The "Acknowledge" function ("OK") is integrated into the
push-dial.
The "Info" and "Esc" buttons are labeled accordingly on the
housing.
The "Alarm" button is not named on the housing, but can be
identified by the alarm symbol.
Press the Info button or, more briefly Confirm with OK.
1.3.3 Notes
STOP Caution The symbol shown here acts as a warning in cases where an
action may result in permanent loss of data.
Important This indicates an important statement which requires your
special attention.
Note A "Note" qualifies an immediately preceding statement or
statements.

2.3 Display panel
Figure 2-6 Opening screen
The PXM10 has a five-line display. It can be used to view all
the visible elements of a plant with values or other
information. Figure 2-7 shows the layout of the display. The
areas of the display and the symbols used are described in
the next section.
The push-dial and buttons used for navigation and editing
are adjacent to the display panel, set into the housing itself.
These buttons are described in Section 2.2.

A line highlighted in inverse video (light print on dark
background) indicates an option associated with one or more
hierarchically subordinate lines; you can display these with
the push-dial.

If a line of text is outlined, this indicates that you are at the
lowest level, and you can only read, but not edit the value on
this line. Use the Esc button to navigate back to the next
higher level.

3 Commissioning
the PXM10
The PXM10 is used for local operation of a compact or
modular DESIGO PX automation station. No user login is
required. The PXM10 allows you to work at the "Basic" and
"Standard" operating levels.
All the objects from these operating levels are mapped in the
device.
"Favorite" objects are defined at the engineering stage and
mapped separately.
Step Action
1 Mount the PXM10 on the housing of the modular
automation station.
or Connect the PXM10 to the compact or modular
automation station with a PXA-C1 cable.
2 After a few seconds, the display will light up and
the opening screen will appear. The PXM10 is now
ready for operation:
Figure 3-1 Opening screen
3 Either open the plant data with OK
or Press the alarm button to go directly to the alarm
list.
The PXM10 and PXM20 can be used in parallel for operation
and monitoring of a PXC…-U automation station by
mounting the PXM10 directly on the automation station and
connecting the PXM20 to the MMI/tool socket with a PXA-C1
cable.

If the PXM10 connection is interrupted briefly, it may take up
to 15 seconds for the polling cycle to resume. The display
can be re-enabled by operating any of the operator controls.
There is no need to log out.
Wait 30 seconds before reconnecting.

5 Alarms and events
The LED display in the alarm button lights up in response to
incoming alarms and events, and, in the case of alarms,
starts flashing.
Events do not require acknowledgement, nor do they appear
in the alarm list.
5.1 Pop-up windows
If an alarm or event occurs while the PXM10 is in operation,
you will be notified accordingly in a pop-up window (Figure
5-1). If the PXM10 is only switched on after the occurrence of
the alarm or event, there will be no pop-up window. These
alarms do, however, appear in the alarm list.
If you want to be notified of events in a pop-up window, you
can activate this option under Settings > Event popup.
Figure 5-1 Settings screen Figure 5-2 Activate event pop-up window
A pop-up window contains the main information about the
event or alarm concerned:
