SMART-BUS Compendium
1. System Philosophy and Components
The SMART-BUS System is based on the standard RS485 for industrial-used serial bus. This was expanded of a
adjustment software which is easy to use and the intelligent hardware-based CSMA/CD Technology which guarantees that the bus provides an ideal performance of data transmission at any time. This happens regardless
of how long the bus is, or how many devices are plugged into it.
Both, star and in-line topology can be used in the SMART-BUS bus.Therefore the overall system can accommodate up to 255 individual strands, each with up to 255 devices. In theory up to 65 025 devices can be brought
together in a large bus network. The single strands are combined through gateways, which are additional a
vertical conjunction to the ethernet.
Because of standardized use of the bus and open data protocols from SMART-BUS it is easy to bring the
SMART-BUS devices or a created network or a on SMART-BUS based application with other systems like central
visualization systems, security systems, fire alarms, enlarged media technology, etc. without any loss together
and establish very special and very stable system solutions.

1.1 SMART-BUS bus protocol
SMART-BUS mainly uses TCP/IP and RS485 for data communication and offers in some devices also direct
applications and features in protocols like RS232, DMX512, DALI, OPC, KNX (former EIB) and other protocols,
witch can be also bidirectional according to device and application.

1.2 SMART-BUS system parameters
▪ The maximum number of subnetworks in the overall network is 255.
▪ The maximum number of devices per subnetwork is 255.
▪ Each RS485 device line holds up to 64 physical devices.
▪ Each subnetwork is connected via ethernet to the other with assistance of a gateway.
▪ The voltage in the bus is constantly 24V DC (24V/DC).
▪ The bus baud rate is 9600 bit/s, so he is a fast data bus.
▪ SMART-BUS is a so-called „distributed control system“.
▪ The bus has an automatic system recovery after a power outage.
▪ The bus devices can be inserted into the running bus (warm start technology).
1.3 SMART-BUS system components
A SMART-BUS system consists of three parts:
▪ System device.
▪ Output device.
▪ Input device.
The detailed description can be found in part III of this system manual.

2. System Properties and Applications
2.1 Benefits of the SMART-BUS System
The main benefits of SMART-BUS are a simple network design, easy system installation, easy
handling and installation as well as a very easy maintenance. Also the simple hardware structure, easy programmable flexibility via software and favorable pricing system are characterized
by the system further.
Because of many interfaces and command input or function selection by the user and the parallel far-reaching automation of the system make the use convenient and self-evident simple.
The data information of all devices are separately saved. So a failure of a individual components
would not cause a system crash and would not let the user in case of doubt alone. The settings
are always protected against total power failure and the system restore to basic status by its
own after it is put back into operation (e.g. after a power failure).
▪ Control and actuator channels (dimmers, switches) are separated entities and the connection of devices is implemented via 4-pin cables with low voltage.
▪ The relative openness of standards system offers easy integration to other building management system (BMS) and facility management software, security, fire detection or other
systems.
▪ Through bidirectional data communication the system provides constant status overview
and status report as well as links to external monitoring equipment.
▪ The system has an automatic error message output.
2.2 SMART-BUS control options
▪ lighting control
▪ media control and communication rooms
▪ housing and exclusive home
▪ building and automation technology
▪ show exhibition halls, museums and adventure areas environments
▪ SPA and wellness facilities
2.3 SMART-BUS control options
Infrared Remote Controls
The system is able to learn easy IR commands and put them out again (for example to integrate DVD players,
monitors, receivers) and can also be controlled via remote controls.
Ex factory preussen automation SMART-BUS supports all Logitech and Philips multifunction remote controls and
can be also scanned in other remotes.
This possibility is mainly used in home theaters, living rooms, hotel rooms and other home environment.
Similarly to the infrared remote control, radio remote control systems can be used. SMART-BUS has receiving
modules which support remote-controlled applications. Examples are garage doors, wireless outlets, etc. This
possibility is mainly take effect in home environments.

SMART-BUS Compendium
PDA / Touch Screen and PC Interface
Commands can be accessed directly from PC-based environment through the IP interface.
Examples are Touch Displays, PDAs or terminals like in conference environments, control rooms or in the superior private sector. Here, advanced IT applications make the automation almost limitless.
Switch
preussen automation SMART-BUS offers a series of intelligent switches with and without display functions. So
commands can be given from stationary positions to the system and retrieve any type of programming. Lighting scenes, entire shows, automated processes and any other commands from vertically integrated environments (e.g. TV On/Off) can be triggered with it.
The switches are used in all environments and because of small I/O modules also convention switch can be
quickly converted into the intelligent SMART-BUS input units.
Motion Detection
Motion sensors can activate or stop actions and settings, or call additional functions to within existing settings.
Especially in the area of energy, these components help to save power when no one is in the area. Of course,
these actions can be extended to include additional sensor conditions (e.g. light switches on only if it is dark
outside).
Brightness (lux meter)
Brightness sensors call light scenes or other programs automatically at preset thresholds, or hold on a particular dimmer brightness level in relation to ambient brightness. As with all other sensors in the SMART-BUS
system, these actions will be expanded to include additional sensor conditions.
External Control Signals
I/O modules make the inclusion of external control signals very easy. The simplest example of integration are
classical limit consumption or switch which can call the SMART-BUS system with simple contact entries (closed/
open/keyed).
Time Control
An available system clock makes all the actions also time-controlled possible. The change of seasons and local
variations in conditions can be deposited, and as well as additional sensors for comparison be in the automation
included.
Logic Control
The full integration of any logic brings intelligence into the system. Through full transfer of all relevant data
within the system like SMART-BUS timing, switching states, sensor data, external input status, etc., the system
can make dynamic logical additions without further user intervention.
In this way the system offers the ability to think for itself. We call it Smart-live technology.

3.2 Device Address Settings
Generally SMART-BUS products are addressed by module addresses.
The individual hardware address (MAC address) is set ex factory and provides the unique identification of each
instrument. Within the SMART-BUS bus, the devices are set through the software Officer as soon as the modules are connected to the bus via a gateway.
After this, they can be assigned to a subnetwork and within that subnetwork be fitted with a simple numerical device address, the so-called device ID (e.g. dimmer module is located in subnetwork 2 and has the bus
address 3). You can set the bus address as follow:
Open in the software „Address Management“ and then „Change Address“. Then you will be able to make the
appropriate changes. More information about automatic change of address can be found in the device instructions.

3.3 Device Programming
After the devices on the bus or concept has been arranged as needed, you can program them without extra
effort. To do this, make the desired settings and dependencies in each device menu.
Please take the function details from individual instruction manuals.

3.4 SMART-BUS Network Characteristics
SMART BUS is based on RS485 industry control protocol and the superior network is based on standard TCP/IP
ethernet protocol.
The RS485 topology (network configuration) is a serial bus system, in other words all devices are connected in
series. A star topology is not provided in the serial bus.
You have to connect all the individual serial lines to the superior ethernet to build a star network (star topology). Alternative to this all other ethernet topologies can be created.
Over the ethernet as a backbone medium fiber links can also be used for long distances between different subnetworks.
3.5 SMART-BUS Design Basics
For the planning of SMART-BUS applications, the following guidelines are taken into account:
▪ Each bus (subnetwork line) must contain no more than 64 devices.
▪ The total length of a bus train should not be more than 1000m.
▪ Longer distances up to 2000m can be achieved with gateways.
▪ Different subnetworks are connected via gateways.
▪ The maximum current load of the devices must be observed.
▪ The cross section must be complied in relation to the voltage drop.

SMART-BUS Compendium
3.6 Subnetwork Design Basics
SMART-BUS overall systems can be assembled from many different bus routes. Each subnetwork can contain
up to 255 devices (but the physical single strand a maximum of 64 devices).
In a overall system can up to 255 subnetworks be included, which are connected via gateways. To keep the
flow of data optimal, physically connected devices should be placed in the same subnetwork.

An Example:
On the ground floor of a two-storey house a subnetwork (subnetwork 1) is created, and in the 1st floor a second subnetwork (subnetwork 2).
Both networks are combined via a gateway to a comprehensive network. Now the two subnetwork lines run
independent to each other (the failure of subnetwork 1 does not lead to a failure of subnetwork 2) and the two
networks do not affect the performance, if they want to exchange data with each other via gateway.

3.7 LAN Design Basics
Individual subnetworks are connected via gateway to ethernet and can communicate via ethernet (TCP/IP) to
be combined into a LAN (Local Area Network).
Theoretically, this configuration can be realized (because of ethernet) also via a WAN (Wide Area Network), if it
is necessary.
In each LAN can be a maximum of 254 devices (gateway) which in turn manage the subnetworks (see Basic
Ethernet networks).
3.8 Gateway Basics
For initial programming and for a superior connection of subnetworks is at least one gateway needed to establish an initial connection with the adjustment software on a PC.
For a function of an already programmed subnetwork the gateway is not necessary!
There are two types of gateway devices in preussen automation.
preussen automation Gateway Individual Devices
▪ 1 Port Gateway (preussen automation SMART-BUS RS485/IP I)(Order Code: BD0100801)
▪ 4 Port Gateway (preussen automation SMART-BUS RS485/IP IV) (Order Code: BD0100805)
preussen automation devices with Gateway on board:
▪ Eve Event timer (preussen automation TimeME Plus)
▪ All scene controller
▪ All Bus Interfaces with the expansion: IP
Notes:
Inside a subnetwork a gateway must have the same subnetwork ID like the other devices to be detectable in
the ethernet. The devices have to form a subnetwork as „family“.

3.10 Configuration of the Scene Controller
Scenes are stored on corresponding scene controller. These controller summarize changes that will occur in the
system through input and control the flow of these scenes. They also save the bus assigned functions.
There are two types of scene controller for SMART-BUS
▪ Devices with integrated scene controller i.e. dimmer, relay etc. which already contain the
simple scene controller.

3.11 Rules for Power Supply:
Mainly the SMART-BUS bus uses for power supply the cabinet modules. In particular if they have active functions (dimmer, relays), have a connection to the mains (230V/50Hz) and provide the operating voltage for the
bus. These devices are called as the bus provider.
Devices in low voltage range (switches, sensors) are always supplied with 24V DC from these devices. These
devices are called as the bus consumer.
The exact connection details of devices can be found in the data sheets.
TIP:
Between two devices you only need two wires to the control signal, if they are already brought up to the mains
(230V/50Hz).
Calculate Power
Formula:
S=(P1+P2+Pn)-(C1+C2+Cn)
- 13 ©preussen automation GmbH 2010
SMART-BUS Compendium
In the given formula are:
S = bus power in amps
P = device connected to the mains (bus provider)
C = device without connection to the mains (bus consumer)
Note 1: It is important that the sum of devices which do not supply the bus (bus consumer) is not bigger than
the sum of devices which supply the bus (bus provider).
Note 2: The voltage drop must be taken into account for long distances. The input voltage at the screw terminal of the devices should not be less than 15V.
Note 3: The total current in the bus must not exceed 3 amperes (3A).
A small example:
In a project (e.g. multi-purpose hall) is a larger dimmer installed which supply the bus with 100mA/24V. For
that 15 wall switch type PicSwitch 25IR were combined to turn off the lighting from many different places. Each
preussen automation PicSwitch 25IR consume 15mA/DC24V.
The total consumption is: (15 × 15mA) = 225Ma = 0.225A/DC24V
It follows from the above formula: S = (P) 100mA - (C) 5x15 mA
So we note that S is negative: S = -125mA
Currently only 100mA were available and for this reason S is negative. So we need in this example an additional power supply. (Note: Most bus provider devices supply higher current into the bus. Thus, power supplies
can be abandoned usually.)

3.12 Cabling Plan
The best and cheapest way to connect the SMART-BUS system to each other is on Cat 5 cable. But all the other
cable types which are suitable with the specification for RS485 communication are also possible. In any case,
the line for longer routes should be screened and should have for new installations the length of the cable cores
appropriate cross-section.
It is recommended that the cables which lead main voltage (230V / 50Hz or more) keep at least 300 mm distance to each other in order to minimize the noise.
At best the devices should be connected in series (serial hand to hand principle). But the combined connection
terminals of the devices allow also other compounds (see charts).

3.13 Integration of SMART-BUS Systems
The best way to integrate the SMART-BUS system in fire alarms and security systems is over the contact modules.
This allows to set all lights in case of fire to 100%, all audio sources to off and so on. Practically every application can be created that will be guaranteed in event of failure of the control voltage by the default settings of
the devices.
Over the ethernet interface can be implemented various TCP/IP-based integrations in addition. preussen automation provides support for this project and many examples as well as references.
