21.2 Desigo TRA (Total Room Automation) New guidelines to save energy, lower operating costs as well as greater requirements for comfort and design require more sophisticated interaction of the various technical installations in buildings. The PXC3 modular room automation stations combine lighting, shading, and HVAC in one total solution and provide a direct connection to the PX automation stations via BACnet/IP.

PL-Link allows for integrating field devices such as room operator units, buttons, motion detectors without engineering. Desigo TRA is the perfect room solution by supporting also KNX, DALI, and EnOcean devices.

21.2.1 Technical principles - Definitions

PXC3 room automation stations: • PXC3 assume control functions for one or multiple rooms. • PXC3 communicate with each other or other system components via BACnet/IP.

Scope and functionality of supported BACnet objects are matched to the requirements of room automation.

• PXC3 provide a 2-port Ethernet interface for cost-effective cabling via line topology. • PXC3 contain bus supplies for island bus, PL-Link, and DALI. Internal bus supplies can

be extended for island bus and PL-Link as needed. TX-I/O modules connect field devices directly to the PXC3 room automation station, supporting flexible and fast installation and commissioning. PL-Link (PeripheraL Link) connects communicating room and field devices (room devices, sensors, actors) with the PXC3 room automation station.

Plug&play allows for connecting selected Siemens field devices to the PL-Link using plug and play.

PL-Link allows for integrating third-party devices (via ETS4 engineering for KNX S-mode). PL-Link is not suitable for KNX subsystem integration, as communication is not directly between field devices but field devices and room automation station.

PL-Link has bus-internal supply allowing for cost-effective installation without requiring additional wiring. The 2-wire bus allows for connecting up to 64 devices.

A comprehensive library with preconfigured devices supports simple engineering.

PL-Link provides extended functionality and additional diagnostic functions compared to direct connected field devices.

DALI (Digital Addressable Lighting Interface) helps control lighting.

Commercially available DALI EBs (electronic ballast) and dimmers can be connected to the PXC3..A room automation station via DALI. See also DALI homepage: http://www.dali-ag.org/

Compared to DC 0...10 V control, DALI offers additional functionality by means of bidirectional data exchange (status query, set state, etc.).

DALI allows for creating any type of topology (except ring) at up to 300 m and 64 devices.

DALI uses a 2-wire bus protected against polarity reversal. No terminating resistances required.

EnOcean is a radio technology for sensors, actors, and room units that is normally operated on integrated solar cells without need for maintenance (no battery exchange).

PL-Link, its KNX S-mode gateway, and ETS4 engineering allow for easily integrating EnOcean radio room units in TRA without requiring maintenance.

In TRA, numerous system elements and system data are grouped by means of grouping functions. • Groups allow structuring and central control of system elements and data. • Groups support data exchange between central control functions and individual system

elements. System elements and data can be grouped by either geographical, functional, or discipline-specific criteria. Typical reasons for exchanging data within a group: • Distributing common group data by central function. • Collecting data from individual group elements. • Calculating resulting group data via central function.

The flush-mounted room unit QMX3.. in rooms featuring individual room control is used to operate HVAC, lighting, and blinds functions. The room unit uses PL-Link to communicate with the PXC3 room automation station. Commissioning is fast and easy on the device (plug&play).

The device is operated via 4 operating lines with one display and 2 operating buttons each. The top operating line shows the currently selected menu, the lowest is used to navigate within the menu. The 2 middle lines are used to display or operate values (temperature, setpoints, air quality, fan, scenes, etc.).

The leaf symbol of the Green Leaf function tells the room user if the room is operated efficiently. • Leaf is green = Energy-optimized operation • Leaf is red = Excessive energy consumption Pressing the leaf symbol returns room control to energy-optimized operation.

Separate lighting and blinds switches are needed to operate lighting and blinds. Existing scenes comprising HVAC, lighting, and blinds functions can be adapted to user requirements directly on the room unit.

21.2.3 Integration in automation level

In Desigo TRA, the following central functions generally are best implemented on a PXC00-E.D (or another PXC…-E.D): • Alarming: Alarm notification occurs via event enrollment object stored on the PXC00-

E.D. • Scheduler: Central TRA functions are controlled by scheduler objects stored on the

PXC00-E.D.

ABT (see 21.2.8) offers the following functions to engineer alarms and schedules: • Event enrollment objects in the PXC00-E.D are generated automatically based on the

project data from the linked PXC3. • When engineering the PXC00-E.D, the BACnet reference browser supports

engineering and management of BACnet objects in the PXC3.

Project data from all PXC and PXC3 of a project are integrated in XWP project storage. This allows, e.g., for cross-project checks, network checks, and use of the BOS (branch office server).

21–13


21.2.4 Integration in management level

Desigo TRA is best integrated in the management level using automation station PXC00-E.D.

The PXC00-E.D has two main tasks:

• Exchange TRA data with the primary plant and upload alarms to management station. • Execute higher functions (alarms, trend, grouping, schedules etc.).

Figure 21–1 Integrating Desigo TRA in the management station

21–14


21.2.5 TRA application functions

The PXC3 room automation station is programmable based on proven application functions. A comprehensive application functions library for room automation is provided as part the scope of delivery of Desigo V5. The library contains predefined application functions for room climate, lighting, shading, and higher room functions. They can be combined to form individual solutions together with operating and display functions. The individual application functions can be adapted to customer needs or freely programmed. Room climate • Temperature control (heating, cooling) with radiators, chilled

ceilings, fan coils, VAV systems. • Operating modes (Comfort, PreComfort, Economy,

Protection). • Start/stop optimization or boost heating. • Night cooling, downdraft compensation. • etc.

Room functions • Scene control. • Occupancy evaluation. • Energy optimization together with HVAC and blinds. • Green leaf function

Lighting • Switching, dimming. • Constant light control. • Automatic lighting based on daylight switching. • Dusk/dawn switching. • Stairwell lighting.

Shading • Anti-glare protection with automatic solar protection or slat adjustment.

• Automatic thermal function for day and night. • Automatic dusk/dawn adjustment. • Weather protection (rain, wind, frost).

Sensor functions

• Presence detection • Window monitoring • Dewpoint monitoring • Temperature measurement

• Brightness measurement • Air quality measurement • Wind speed measurement

(central) • Precipitation detection (central)

Actor functions

• Actuator • Lighting actor • Blinds actor

Local operating /display functions

• Set temperature setpoint • Select room occupancy • Operate fan coil • Green leaf function

• Call up / memorize scene • Switch/dim lighting • Set solar protection

Many application functions are preconfigured and available in the library. Retroactive configuration during engineering or commissioning is possible. Own configured application functions and entire rooms can be stored in a project library. The application architecture does not depend on the field device interface. Field devices can be connected directly to the PXC3 room automation station (via TX-I/O modules) or via bus (PL-Link, KNX, or DALI). Many field devices are preconfigured and available in the library. Retroactive configuration during engineering or commissioning is possible. Project-specific field devices configured accordingly can be saved in a project library.

21.2.6 Rooms and room segments

Desigo TRA basically offers two methods to structure a building: • Rooms (with fixed walls) • Room segments (typically based on movable walls) One of the two methods or a mixture thereof is possible depending on the building structure or required flexibility (e.g. during use phase).

Figure 21–2: Rooms and room segments

A room segment is the smallest indivisible element. A room comprises at least one or several adjacent room segments. A room segment is defined and created only once. Room segments typically are combined several times to rooms over the course of a building's lifecycle.

21.2.7 Central control functions and grouping

21.2.7.1 Central control functions

Central control functions allow for and support central control and coordination of any elements. Typical central control functions: • Central occupancy definition. • Central setpoints. • Central hot water/chilled water coordination (optimization of primary plants, supply

chain optimization). • Central lighting control. • Central blinds control.

Different sources serve as input for a central control function:

• Signals from external system. • Signals from system user. • Signals from building user. • Signals from third-party devices. • Commands from scheduler program. • Commands from a higher, central control. The signals and commands are evaluated by the central control function. The central control function sends the result to the subordinate control functions via group master and group members.

21–17


21.2.7.2 Grouping

Groups allow central control functions to distribute and collect values. The grouping concepts comprises two interrelated aspects:

• Group display: Display of groups as standardized information in the building automation and control model to organize central control functions.

• Group communications: Typical reasons for exchanging data within a group: – Distributing common group data by central function. – Collecting data from individual group elements. – Calculating resulting group data via central function.

Grouping functions help structure and centrally control large numbers of different system elements and data. Grouping can follow either geographical, functional, or discipline-specific criteria. Group cooperation supports data exchange between central control functions and individual system elements.

21.2.7.3 Group categories

Groups are divided into categories to differentiate between different scopes of application such as: • Setpoint groups • Occupancy groups • Supply groups • Lighting groups • Blinds groups

– Wind protection – Anti-icing protection – Scheduler – Window cleaning

21.2.7.4 Hierarchical grouping

Central control functions can be organized hierarchically, e.g. by:

• Room • Zone (multiple rooms) • Floor • Section (e.g. for facade cleaning) • Facade • Building • Technology (wind, protection of blinds against rain) • User (system operator, building user) • Emergency criteria (escape routes, fire zones, sections) Hierarchical grouping allows for selective as well as cross-building central control.

21.2.8 Engineering workflow for TRA

Desigo V5 offers the tools ABT (Automation Building Tool) and SSA (Setup & Service Assistant) for TRA.

The ABT tool allows for creating TRA solutions in a project from predefined, flexible application functions and distributing them across the PXC3 room automation stations in the rooms. ABT supports mass operations in a building e.g. to group objects for central functions or to parameterize rooms in a building. The SSA tool allows for configuring the PXC3 room automation stations for a BACnet/IP network, load I/O configurations, and test the wiring. In addition it allows for updating the firmware. SSA primarily is intended for wiring tests. To do this, the electrical engineer connects the laptop (via USB or LAN) to the PXC3 and carries out all work online via a web interface on the laptop. The TRA tool components are integrated in XWP from Desigo V5. The data is also managed on the BOS. Several engineers can work simultaneously on the same TRA portal (satellites) during commissioning. There are different workflows for the different roles: • Project creation (design engineer) • Installation (electrical installer) • Commissioning (commissioning engineer) • Library creation (application engineer) The design engineer creates a project primarily by using library elements. The electrical installer installs and configures the network and the devices. The installer also carries out a function test (wiring test).

The commissioning engineer commissions the plant based on the project data.

The application engineer creates new CFC charts or application functions for a specific project or for the country library.

Working with satellites in the project Satellite projects in ABT are created for two reasons: • Satellite projects allow for concurrent work by different project members. • Satellite projects allow for dividing up projects in partial projects within system limits

(e.g. max. number of rooms per ABT project).

If an ABT project is divided up into satellite projects, both the building structure as well as distribution of central functions on one or several PXC00 must be considered. The building topology, grouping within the building, and central functions in the building as well as library creation must be carried out in the base project.

21.2.8.2 Library creation

This is an expert task to be considered for the following aspects: • Creating applications as per the application concept. • Standardization of interfaces for efficient work (e.g. autoconnect). • Standardization of texts. • Testing application functions. • Documenting application functions.

Siemens From Desigo V5 – Technical principles CM110664en21_06 Building Technologies Room automation – Desigo RXC 30.03.2012

21.3 Desigo RXC The Desigo RXC room automation system controls and monitors comfort conditions in individual rooms. It provides predefined solutions for HVAC, lighting and blinds.

The range consists of a number of room controllers, plus operator units and predefined applications. The applications are configured and downloaded into the room controllers with the RXT10 commissioning and service tool or a standard LNS tool.

21.3.1 Technical principles, terms The Desigo RXC room automation system is based on LONWORKS technology. To integrate Desigo RXC into the automation level, the RXC data is mapped to BACnet. For this reason, the terminology used is derived from the "LONWORKS" and BACnet" worlds.

Figure 21–6: RXC room automation

Refers to the connection of network variables of the same type between different nodes. When a LONWORKS network is designed, these bindings are created with a LONWORKS tool (in the case of the RXC system, this tool is the RXT10 commissioning and service tool or a standard LNS tool).

Network variables connected in this way communicate implicitly. In other words, if a value changes, the new value is transmitted automatically. Transmit and receive times are also monitored, making it possible to react to communications errors.

A binding template contains a number of connections between nodes, or connections to the LONWORKS system controller. A master binding template and a slave binding template are available for each RXC application. The master binding template contains the main data points required for integration.

21.3.2 Desigo RXC range overview Desigo RXC is an innovative product range comprising room controllers, extension modules, and room units. Data communication is based on LonWorks.

The range comprises compact and modular room controllers, easy-to-operate room units and controllers in room-style housings.

The input and output configurations of the room controllers, and the style of housing are fully optimized to suit their field of application.

The modular room controllers include basic modules for HVAC control, which can be combined with extension modules for control of lighting and blinds.

The HVAC functions are operated with standard room units or controllers in a room-style housing. A configurable flexible room unit is available for combined operation (HVAC, lighting, blinds).

Figure 21–7 Hardware Desigo RXC

All the room controllers, and the flexible room unit, are loaded with application software (referred to here simply as the "application") which contains the control program for the associated room or area.

Siemens Building Automation maintains a comprehensive library of applications covering a wide range of HVAC and electrical applications [25].

The RXT10 commissioning and service tool or a standard LNS tool is used for the engineering and commissioning of a network incorporating the Desigo RXC range. This tool also supports the creation of communications bindings between LONMARK-compatible devices (Desigo RXC or third-party devices).

For operation in Object Viewer, no additional engineering is required in Desigo Insight. For operation in Object Viewer, no additional engineering is required in Desigo Insight.

Operation may be either via groups and rooms or directly via the Discipline I/Os.

21–26


A typical requirement in the case of room integration is a graphical representation of the building, showing the different floors and rooms.

Desigo Insight provides highly efficient support for the generation of graphics and the integration of RXC.

For each RXC application, there is a predefined graphic (super genie) in the Desigo Insight graphics library, containing the main data points. The information contained in the super genies is the same as the information in the binding templates in the RXT10 tool.

The super genies are easy to allocate to a specific room:

21.3.4 Integration in the automation level Desigo RXC is integrated into the automation level (PX) by means of the LonWorks system controller.

This system controller has two main tasks:

• to map the RXC data to BACnet objects, and • to implement higher-level functions (grouping, time schedules etc.). On the "BACnet side" of the LonWorks system controller, the RXC room controllers can be operated and monitored from a client (PXM20 or Desigo Insight). Further, data can be exchanged with the primary plant.

Figure 21–11: RXC system overview

21–28


21.3.5 RXC applications Desigo RXC applications are standard applications developed at HQ. They cannot be modified for a specific project by the user. These applications is loaded to the room controller using the RXT10 commissioning and servicing tool or using a standard LNS tool (commissioning).

Applications of the same type are grouped into "application groups". The complete range of RXC applications is held in a library which is added to continuously.

Figure 21-12 Hierarchical structure of the applications library

21.3.5.1 RXC application library

The RXC applications library contains application groups, each of which contains applications of the same type (see Section 21.3.5.2).

The RXC applications library has a version number which is defined in the RXC Valid Version Set. This Valid Version Set also defines the version of each individual RXC application.

The structure described above can be seen in the documentation and in the implementation of the RXT10 commissioning and service tool.

21.3.5.2 Application groups

Similar types of application are grouped into "application groups".

These differ from each other in terms of how the functions are implemented. Thus "Chilled ceiling with radiator" (CLC02) and "Chilled ceiling and electric radiator" (CLC03) are two different applications within the CLC group. The first of these two applications uses water for heating, while the second uses electrical energy. The difference between applications in the other groups follows a similar pattern.

21–29


Currently, the application groups are as follows:

000 Basic application (allows the RXC room controllers to be used as I/O modules) RAD Radiator applications CLC Chilled ceiling applications. FNC Fancoil applications. VAV Variable air volume applications. FPB Fan-powered box applications (fan-assisted VAV) INT Integrated applications (combined applications including lighting and/or blinds) IRO Integrated room operation (applications for the QAX50/51 flexible room units)

21.3.5.3 Individual applications

The individual application is designed for typical HVAC systems as commonly used in practice in individual rooms.

Examples:

FNC10 2-pipe system with changeover and outside air damper

VAV06 Single duct supply and extract air system with electric re-heater

Applications are modular in structure, and cover a specific combination of functions which are always implemented in the same way.

So, for example, operating modes and setpoint derivation are identical in all applications (including those in different application groups). Similarly, fan speed control is identical in all FNC applications.

21.3.5.4 Application configuration

Each application has a defined number of configuration parameters with which the application can be programmed for a specific project. These parameters consist both of general values (such as temperature setpoints etc.) and of specific values for the application concerned (e.g. changeover configuration, electric reheater etc.).

21.3.6 Map LONWORKS in the LONWORKS system controller RXC data in the LONWORKS system controller is mapped by use of objects which gather together the main functions of the RXC applications. The LONWORKS system controller thus operates as a data concentrator (the data points are not mapped individually).

These objects are referred to as Discipline I/Os and are components of the block library.

The following types of Discipline I/Os exist:

• HVAC: Comprises all the HVAC information

• Light: Comprises all the information relating to a lighting group

• Sunblind: Comprises all the information relating to a group of blinds

• Shared Contains shared data points (e.g. time schedules, occupancy status etc.)

The Discipline I/Os are defined in accordance with the "Maximum" principle, i.e. one HVAC Discipline I/O contains all the information found in the HVAC part of the RXC application.

When mapping an application, however, only the specific data points for that particular application are mapped to BACnet.

21.3.7 Groups in the LONWORKS system controller The RXC room controller data is grouped in the LonWorks system controller. The Discipline I/O itself can be viewed as a preliminary form of grouping: it groups the data for the different sections (HVAC, lighting and blinds) of the RXC applications into the associated objects (see Section 21.3.6).

With the LONWORKS system controller, a distinction is made between the following groups:

• Room-based groups (grouping of Discipline I/Os into a room) Compounds • Cross-room groupings (groups of rooms) firmware

21.3.7.1 Room-based groups

Essentially, a room-based group is a structuring element. If more than one RXC room controller is installed in a room, only the Discipline I/Os of the master controller will be integrated. In such cases, master and slave are connected at the field level.

A room-based group accommodates all the Discipline I/Os of one physical room. This leads to a room-based view.

The second function of the room-based group is the mapping of application-specific data to BACnet – i.e. the selection of those points of the Discipline I/Os which are needed for the RXC application concerned. Room-based groups are implemented in the form of "Compounds" and contained in the PXR Compounds library. There is a room-compound for every RXC application.

21.3.7.2 Grouping across rooms

A cross-room group contains all the control variables common to a given group of users (e.g. North façade, Tenant A, West zone etc.), and distributes these control variables to the associated room or group members.

For this reason, a cross-room group contains two "member lists", one for the referenced room and one for the referenced group.

Cross-room groups take the form of blocks and are contained in the block library.

Referenced rooms are referenced via the Discipline I/O of the room-based groups (see Section 21.3.7.1.

Only rooms connected to the same LONWORKS system controller can be referenced.

The addressed rooms cannot be modified online.

A cross-room group can also transmit values to another group. This may be connected to the same or another LONWORKS system controller.

Up to 5 more groups can be addressed. These references can be modified online.

A group can only distribute information. It is not capable of gathering data.

21.3.7.3 Types of groups

The following types of group are available:

• Changeover: Transmission of the changeover signal (LTHW or CHW in pipe work).

• Setpoints: Basic setpoint correction and setpoint adjustments.

• Emergency: Override of supply/extract air dampers in the event of fire/smoke.

• Outdoor temperature

Distribution of outside air temperature.

• Lighting: Transfer of lighting control and forced control of lighting

21.3.8 System functions System functions are higher-level functions which are typically applied to groups. They are thus stored "upstream" of the groups and connected to them as part of the data flow. System functions are implemented in the form of Compounds and are part of the compounds library.

The system functions are as follows: • Summer/winter compensation

This function adjusts the setpoints as a function of the outdoor temperature. So, for example, the heating setpoint is raised in winter as the outdoor temperature falls.

• Changeover

This function is used when both heating and cooling are required in a room, but only one water pipe is installed. The changeover information is mapped in the LONWORKS system controller and transmitted to the RXC room controllers via the groups. These switch between heating and cooling accordingly.

• Emergency override This function is used in emergencies (e.g. fire) to force a specific and immediate reaction from the ventilation system in the individual room.

Possible reactions: Close damper, generate positive or negative pressure etc.
