Modular design for universal application
With its modular design, Desigo PX can be adapted to specific requirements and
needs, making cost-effective DDC technology a possibility even in small HVAC
systems. Investment costs are limited to those system components that are
actually needed. This innovative approach allows phased expansion of Desigo PX
into a building automation and control system as and when required.
BACnet communications for maximum openness
Desigo PX sets new standards in relation to present and future communications
technologies. The use of BACnet /LonTalk or BACnet/IP underlines the openness
of our systems and our utilization of the latest communications technologies.
BACnet opens up the system, to allow easy integration of systems and components from third-party manufacturers.

Made-to-measure operator units
The various operator units in the Desigo PX range more than satisfy all the various
requirements in terms of location and function.
Web client (PX-WEB)
The plant can be monitored and operated from a Web client via a Web controller.
In the event of a fault, the Web controller transmits SMS messages and allows
remote diagnostics via Web client.
PXM10 and PXM20
operator units
The PXM10 and PXM20 operator units, which can be optimized for different
categories of user (e.g. resident engineer), offer users an easy means of checking
the operation of the building services plant or of modifying the comprehensive time
schedules to take account of changes in occupancy.
QAX… room units
Room units optimized for building occupants can be used for simple and direct
local operation of the plant. In this way, the room temperature in a conference
room, for example, can be easily adapted to individual needs.
A family of programmable automation stations
PXC… automation
stations
With the PXC… family of programmable automation stations, Desigo PX offers
maximum flexibility in the control and monitoring of building services systems.
Comprehensive system functions such as alarm management, time scheduling and
trend data storage cover all the requirements associated with the operation of a
building. The distributed automation stations, available in two categories, operate
autonomously. Communication is via the open BACnet protocol.
The D-MAP
programming language
Professional software tools are available for engineering and other processing of
the automation stations.
The starting point for the engineering of the program functions is the range of userfriendly application blocks and function blocks in the new programming language
D-MAP (Desigo Modular Application Programming). D-MAP is optimized for
building services applications and is based on the IEC 1131 standard. The
graphical user interface of the software tools ensures an efficient approach.
Scope for phased expansion
The Desigo PX automation system can be expanded step by step into a full
building automation and control system.
Desigo Insight
The Desigo Insight management station offers convenient multi-user operation
system wide. It can be connected to Desigo PX via Ethernet/IP, LonTalk /
LONWORKS or by modem.
Desigo RXC / thirdparty products:
Integration via SystemController
Desigo RXC room controllers can be integrated seamlessly into the automation
level via the system controllers.
Ethernet/IP LAN
backbone
All parts of the plant can be interconnected via router and Ethernet/IP LAN. The
automation stations also communicate directly on Ethernet/IP, allowing costeffective use of the existing IT infrastructure for Desigo PX.
Third-party subsystems, such as fire detection systems, intruder protection, lighting
or refrigeration plant, can be integrated simply and cost-effectively into Desigo PX.

Monitoring, operation and display
Alarm management
An important factor for the efficient operation of plant is the alarm management
system, which ensures early identification of problems in the plant and initiates
automatic strategies to help prevent any resulting damage.
General alarm mechanisms
Desigo PX is based on the BACnet standard. With three types of alarm, Simple,
Basic and Extended, the method of handling and acknowledging alarms can be
matched to the plant technology. The alarm message is accompanied by vital
information which helps the building occupant to locate the cause of the fault.
• Additional information in text form is automatically added to the alarm message.
• Alarms are identified with a date and time stamp.
• Technical staff can see exactly where the alarm originated – in which plant,
which aggregate and which component.
Automatic information for the plant operator:
Many building services installations are not continuously monitored by technical
staff. This is why Desigo PX automatically transmits alarm messages to a
predefined address.

Overview of plant faults
The plant operator can use the Alarm Viewer function to display all active alarms
and their current status.

operation
Alarm functions
Simple alarm
The standard "Simple" alarm triggers certain reactions in the automation station,
e.g. equipment is switched off, valves are opened, etc. At the same time, the alarm
message is transferred to the specified target operator units and output devices.
There is no need for the alarm to be acknowledged by the customer; however, the
display or the pop-up window of the operator unit can be deleted.
Basic alarm
"Basic" alarms are used for important alarms which require the operator to check
the cause manually. When an alarm occurs, the automation station triggers the
appropriate reactions, such as automatic switch-off, opening of valves, etc. The
alarm message is simultaneously saved and transmitted to display units such as
local operator units or management stations, as defined in the alarm distribution
system. The alarm must be acknowledged.
Extended alarm
The "Extended" alarms, for safety functions, are an expansion of the basic alarm
function. With these alarms, the operator must not only acknowledge the incoming
alarm but also, after checking the cause of the alarm and clearing the fault, reset
the alarm to return the plant to normal operation.
This alarm mechanism offers double security and is especially suitable for safetycritical plant.
Safety aspects
To avoid the loss of alarms in transit, all transmitted alarms are monitored for
transfer and receipt. Any information about faulty transmissions is saved.
Alarm visualization
When an alarm is displayed, the user can see the relevant information at a glance.
The display format is uniform throughout the system.

Displaying the plant status
The building operator can obtain an overview of the status of the building services
plant at any time, in order to initiate any necessary actions. The overview includes
the most important current values, plant status and setpoints.
For a quick and simple overview, the building operator can quickly identify the
current values in the building services plant from the list of the most important
values, and can then initiate the required actions, based on the plant status
displayed (e.g. OFF). Alternatively, the building operator can obtain the required
information displayed directly in a plant graphic page, via a standard Web client
and customer-specific or plant-specific overviews. These graphics-based overviews can also be easily created or customized by the operator.

Monitoring the plant with trend functions
To check the dynamic response of the building services plant, trend functions are
provided which the user can set up as required, to monitor critical equipment or to
log relevant data for further processing.
To do this, the user simply defines which data points are to be monitored and how
frequently. The trend functions can also be combined with other system functions.
Trend logging can be stopped, for example, at a predefined time or when an alarm
event occurs. The logged data is available for analysis at a later date.
With the PXM20, the user has a simple means of logging up to five data series and
displaying them, two at a time, in graph form.
Trend data can be transferred to Desigo Insight.
Checking the dynamic response of the plant using the PXM20
Global data
Every automation station contains all the data necessary for stand-alone operation.
The same applies to shared data such as date/time or calendar information which
is identical for several or all automation stations.
To avoid having to update changes in parameter settings separately in each
automation station, the shared data is treated as "global data" and handled
centrally.
Scheduler/Calendar
The time control of procedures and processes is one of the daily basic functions of
a building automation and control system. Ventilation, heating, air conditioning,
lighting, door locks etc, are controlled on the basis of opening times and working
hours in buildings such as offices, banks, restaurants, department stores and
schools.
Scheduler programs ensure that lights are switched off automatically at the end of
the working day, and that the temperature setpoint in the building is reduced at
night. These schedulers can also be used to ensure that offices are not airconditioned during public and works holidays, and that plant is not kept running for
longer than necessary.
All scheduler programs are directly saved and processed locally at the automation
level. Thus full synchronization of individual processes is ensured at all times.

Optimum scheduling helps save energy and extend the life of the plant.
In practice, building operators do not exploit this potential to the full, because the
time scheduling in their systems is too complex and lacking in clarity. The Desigo
operator units display ergonomically designed time schedules which are easy to
use.

Data access rights
Access rights provide the convenience of filtering information according to the
individual user requirements. This means, for example, that the resident engineer
or service engineer only has access to the information actually needed to do the
job. A distinction can also be made between read access and write access. Certain
users may be able to read a value but not modify it, while other users may have
extended access rights, enabling them both to read and to modify values.
Information to which a user has no access is not displayed to that user on the
PXM20 operator unit.
Access levels
Within the system there are four basic categories of access, ideally matched to
individual user groups. The more experienced the users, the greater the amount of
information to which they have read and write access. These access rights can,
however, be modified at any time to suit a specific project. Up to seven access
levels can be defined.
The basic rule is that users with a given access level have access to all values at
their own level and at all access levels below their own.
Remote management
The Desigo system allows the remote management of building services plant, both
from a Web client and with the Desigo Insight management station.
The following functions are supported:

of all Desigo PX automation stations connected to a BACnet network. As a BACnet
client, the PXM20/20-E automatically reads the data from the Desigo PX
automation stations. It is therefore always up to date and can be replaced while the
system is in operation.
The operator unit has a high-resolution illuminated display for graphics and text,
keys for operation, and a common alarm indicator with an audible signal.
The operator unit can be mounted remotely for compact and modular automation

Programming with D-MAP
The D-MAP programming language (Desigo Modular Application Programming) for
Desigo PX ensures efficient programming and parameter setting for building
services plant. D-MAP is optimized for building services applications. The control
strategies required for and best suited to efficient operation are implemented using
graphics-based data flow programming.
Efficient engineering with blocks and compounds
The project-specific HVAC applications are configured, programmed, commissioned and maintained using the CFC Editor. The CFC Editor is a graphics editor
based on block and data flow techniques. Predefined and tested application
programs are assembled to create compound structures (referred to simply as
“compounds”), and these are then made available in the libraries.
Creating the CFC chart with the CFC Editor
DMAP programming
features
• The basic elements of D-MAP programming are blocks and "compounds"
(compound functional units). These are stored in libraries.
• To create a D-MAP program, the blocks and compounds for the required
functions are put together in the CFC Editor. This process involves creating
instances (of blocks) or copies (of compounds) from the libraries
• The flow of data between blocks is programmed by interconnecting the "pins"
(inputs and outputs) of various blocks
