UGW//micro Gateway
1. Preface
Thank you for using an UGW//micro gateway. A gateway is used to enable communication
between devices that use different communications protocols. It’s typical area of application is
for technical building service equipment. Communication partners are, for example, control
systems, DDC systems, control systems for refrigeration and heat power stations, room
control, safety equipment such as fire or burglar alarm systems, lighting control and others.
For various reasons, these systems use different communication protocols. The protocols
used are variably well suited for different purposes. They differ in speed, complexity, number
of connectable devices, range, and the type of information transmitted.
The UGW//micro Gateway comes in two versions:
• RS-485 bus interface version
• RS 232 serial interface version
This manual is for both versions of the interface. Please take notice about the differences in
handling at the appropriate places

2.8.2 Connection to web server
Overview
An IP connection between the notebook and the UGW//micro must be established in order to
access the internal web server.
The web server provides the configuration settings in the form of websites.
Crossover-cable
If your notebook PC is set up as a DHCP client (the default), you can use the gateway to
provide an IP address. Connect the crossover network cable to your notebook PC, the IP
address is assigned automatically.
Activating the DHCP server (optional)
On request the DHCP = Dynamic Host Configuration Protocol, automatically provides IP
addresses to clients. If your notebook PC is set as a DHCP client (the default), you can use
the DHCP server of the gateway to provide an IP address. Press and hold the gateway reset
switch for at least 10 but not more than 15 seconds. When the status LED flashes green/red
alternately, the DHCP server is enabled.
Then connect the crossover network cable to your notebook PC, the IP address will be
assigned automatically.
Using a manual IP address
If you plan to use an IP-address manually, please set your PC to the following settings:
IP address:
169.254.0.2 (or higher)
Subnet mask:
255.255.0.0

Show search rules
The web gateway search uses "regular expressions" to make even complex searches simple.
A regular expression forms a search pattern by which matching patterns can be searched for
in the text. This type of search varies a lot, which is why a full description cannot be given
here.
A brief description of special characters in a term is given below. For more information, please
see the POSIX 1003.2 standard or – on UNIX systems – in the egrep (1) or regex (7)
documentation.
The most important rules for a search of data points on a gateway:
•
The main element of a regular term is an element that matches a character. Almost
all the characters, e.g. letters and numbers, are such elements. Also, all special
characters can lose their special meaning when a "\" character is prefixed.
•
There is no distinction between upper and lower case letters.
•
A dot (.) always represents any character.
•
A group of characters can be defined with the [and] character. A match between the
search pattern and the text to be searched in this case is successful if one of the
characters in the search group is found in the text which is being searched.
•
. If the first character in the search group is a circumflex ^, the search is reversed.
Example: The term [0123456789] represents a digit, and [^.] means everything
except one point.
•
The same expression can be written more briefly if it is defined as a range: [0-9]. If
the minus sign should appear in the text, it must be placed in front or behind the term:
[-0-9].
•
Outside a search group the sign ^ circumflex and dollar $ are operators representing
a beginning or ending of a line. Example: "^11" is any line that begins with "11", and
"22$" every line ending with "22".
•
An element can follow one of the following repeated operations:
? - The upcoming element is optional.
* - The upcoming element can occur 0 or more times.
+ - The upcoming element can occur one or more times.

•
Two expressions can be composed by one |-operator. The entire term finds the line
that corresponds to one of the sub-terms.
•
The parentheses (and) are used for grouping. Example: x (cd|ab)y finds "xabyba" and
"xcdyef".

4. Protocol properties and data points
This is a general description only, and independent of the existing gateway.
With a gateway, different systems (e.g. Ethernet, RS485, ...) are connected to the building
automation system for data exchange. Since each bus system works with its own data
formats (protocols) (e.g. BACnet, EIB, MS/TP ...) data conversion is performed within the
gateway. In order to convert the input format to the output format, an internal intermediate
format is used. This makes it possible to convert between any two or more formats.
The internal intermediate format consists of individual data points that are to be regarded as
the smallest amount of information. A data point classically consists of an address and a
value.
Example: Analog actual value (measured value) and an address which makes measured
value selectable.
940.Y bac 34.AV 55
Routing address 940
Data point type Y
Analog value
Address type bac
BACnet address 34.AV 55
In addition, there may be other properties, such as plain text or special identifiers, which can
for example report that the measuring sensor is out of order. To facilitate data exchanges
between different protocols various data point types are provided in the gateway. These data
point types meet the specific requirements of each protocol.
4.1 Control via configuration data
The configuration of the gateway occurs via text files. There is one file per driver with protocol
information (e.g. baud rate) with the extension .cfg and a file containing the definition of data
points with the extension .txt. The file named dispatch.txt contains the mappings of the data
points of the protocols to each other.

Examples of configuration files
The files all have the same basic structure: there are so-called sections (areas) that begin
with a line containing a name in square brackets. The lines following belong to such a section
up to the next section or to the end of the file. The lines following section names have the
structure Keyword = value
The files can also include blank and comment lines at any point – introduced by the #
character. Upper and lower case are distinguished.

4.2 Classification of protocols
Protocols can be classified according to several criteria. These properties must be considered
part of using the gateway.
Protocol properties table
Topology
Point to point
connection
With point to point connections the
connection is between two
communication partners. Compared to a
connection with several participants, the
protocol can be simple, since
addressing different participants is not
necessary.
Bus
Bus systems allow multiple users to
share access to one transmission
medium. The ability to specifically
differentiate, connect and coordinate
access of many devices to the common
transmission medium is more complex.
Communication control
MasterSlave
PeerToPeer
Transmission control
Event-controlled
Poll end
Transmission medium
4.3 Property and data point definitions
Data points are differentiated according to different categories. The data points behave
differently depending on their classification and must be treated differently according to the
gateway configuration.

UGW//micro Gateway
4.3.1 Client-server relationship, data points
In a client-server relationship a server is available to connected clients. The server accepts
requests from clients and then sends the requested data to the client. This is similar with
regards to the relation of data points to each other.
Example: A field device controls an actuator with feedback.
An automation station is intended to set the control variable and evaluate the feedback. The
data points’ control values and feedback are within the field device, which is then the server.
Through reading and writing the automation station accesses these data points and is thus
the client in this communication. Normally, all data points of a device are client as well as
server data points.
For some protocols, it can also happen that both client and server data points are in one
device.
4.3.2 Actual values — set values data points
Actual values are values that are measured or calculated by the server and the results are
transferred to the client.
Set values are values that are meant to affect the behavior of the server through the client.
In set values, another important distinction is whether the value is transferred only by the
client to the server, or whether the actual value of the set value must also be reported back to
the client.
Example: A typical example of an actual value is the mapping of a temperature sensor.
A typical set value would be a nominal room temperature set value in a room controller.
4.3.3 Analog – binary – multi-level – more complex types, data points
Data points also differ as to which values are allowed.
We distinguish:
•
•
•
Analog values (e.g. temperature reading sensor)
Binary values (e.g. relay output)
Multi-stage values (e.g. status data point with the operating conditions: Normal
operation, Off, Economy mode, Failure).
In some protocols there are more, sometimes complex data points.
Example: An example of this is utilization times. At times such values cannot or only
indirectly can be shown in the gateway. These include attributes that can detect whether data
points contain a valid value. With set values there is an automatic value, which causes the
server to take over control of the data point itself.
4.3.4 Abstract data point in data point system
For the processing and forwarding of data points within the gateway, information that is
exchanged by a protocol within the gateway is shown in a generalized internal data point.
The properties of these internal data points allow the mapping of the most commonly used
data points in building automation. The linkage between different data points occurs via these
internal data points. Due to the decoupled internal data points, it is possible to simply add
more protocols to the gateway without needing to change the complete configuration. Thus,

Fax: +49 2151 7294-50
Seite 38 von 50
UGW//micro Gateway
the extension of the gateway system by adding another communication protocol in
combination with all previously available protocols becomes possible.
4.3.5 Structuring technical addresses
Within the gateway, data points are identified on the basis of the unique technical addresses.
A complete data point address consists of a routing address, a data point type character, an
address type character and a protocol-specific address.
Example:
940.Y bac 34.AV 55
Routing address 940
Data point type Y analog
value
Address type bac
BACnet addresss 34.AV 55
4.3.6 Routing address
With the routing address, called unit, the communication port of the gateway is selected and
the routing address is defined for each communication port in the fabrication of the gateway. If
a gateway has multiple connections of the same type, the unit typically increases by one.
Example: If a gateway has FMS Profibus twice, the routing addresses are 250 and 251.
4.3.7 Data point type as part of address
In order to be able to use the address to derive specified information concerning possible
uses, the address may contain a code letter. With this the direction of data flow and the type
of values is determined. The four main types are briefly presented here. For special purposes,
other types come into consideration, which will be explained when used.
4.3.8 Data point types
X analog value that is transmitted from the communication partner to the gateway.
Y analog value that can be transmitted in both directions.
M binary or multi-level value that is transmitted from the communication partner to the
gateway.
S binary or multi-level value that can be transmitted in both directions.
! Attention !
There may be several meaningful ways to assign a data point type to a data point. The
selected data point type must be used consistently. A frequent source of error in the
configuration is to use the same data point for different data point types.
4.3.9 Address identification as part of address
In order to be able to correctly interpret the protocol-specific part of the address an
abbreviation of the communication protocol is used.

4.3.11 Mapping possibilities
A mapping basically consists of a source data point and a destination data point. Changes in
the value of the source data point are transmitted to the destination data point. This transfer
can additionally be modified by configuration entries. The address of the source data point is
entered as a section in the dispatch file. The address of the destination point is registered on
another line under the keyword target =.
Example of a dispatch.txt
# mapping of 1 bit value from Profibus FMS on MODbus
[250.M fms 22.2.4]
target = 60.S mod 3 coil 4
# mapping of an analog value from Profibus FMS on MODbus
[250.X fms 4.23]
target = 60.Y mod 7 holding 30

5. Configuration
5.1 Data point files
Which data points are to be used and which properties these data points should have is
determined in the data point file of each protocol.
The file name is derived from a protocol-specific part of the name, a serial number, which is
numbered in the event of multiple connections for the same protocol and the extension.txt.
Example of a gateway with two EIB connections:
eib1.txt and eib2.txt.
The name of the protocol-specific part is mentioned in the description of the designated
protocol.
The address of the data point serves as the section’s name. An abbreviation of the address is
used. Since the routing address and the data point type have already been determined by the
file and they are not indicated again. This means that the full address 60.X eib 2/3/5 is written
in the list data point as X 2/3/5.
The use of the following key words is standard:
name
Optionally, you can specify a plain text for the data point here. The text is
usually only used for commentary purposed within the gateway. In some
protocols, e.g. BACnet, the text is used in the protocol. This is especially
mentioned separately each time in the protocol description.
format
Optionally, here protocol-related properties of the data point are described
which cannot be derived solely from the address. For example, it is
common to transfer analog values of many protocols using a scaling factor.
This scaling factor must be specified in the configuration, so the gateway
can interpret this value correctly. The available data are protocol-dependent
and are described in the respective chapters.
write cache
Optionally, possible values YES or NO (default). This parameter only has
meaning for those parameters whose value is described by the gateway. If
the option has the value YES, the gateway remembers a value during a
failed entry and repeats its entry attempt, when for example the connection
to the device has been restored. If this option is missing, or your value is
NO, the value is discarded after a failed entry.
A scenario for a meaningful application of this option would be to make a
binary fault visual via EIB. If the EIB bus is not connected to the gateway at
the time of occurrence of the failure, the gateway naturally cannot report the
failure. When the connection has been restored the fault condition should
generally at least be is transmitted afterwards.
A scenario where this behavior is not desired would be the switching of
room lighting. If at the time of the switching the EIB does not work, it is
generally not desired that the switching takes place after the event (e.g.
after several days).

query
Specifies how the data point should be picked up via the corresponding
protocol. Each of which, with a few exceptions, is described separately and
uses the value permanent abbreviated as pe here. This value is standard.
further
options
For some protocols, there are other options that need to be projected at this
point. The description can be found in each of the protocol chapters.
5.2 Configuration files
The file name is derived from a protocol-specific name part, a serial number, which may
number several links of the same protocol and the extension .cfg.
Example of a gateway with two EIB connections:
eib1.cfg and eib2.cfg.
The name of the protocol-specific part is specified in the description of the corresponding
protocol.
General parameters for each connection are established in the configuration file for each
connection. Typically, information such as baud rate, individual addresses or poll rates should
be indicated. The content consists of a section with a protocol-specific description and
configuration entries.
Example 5.1. Modbus sample configuration file modslave1.cfg
# Modbusconfiguration
[MOD]
baudrate = 9600
mode = 485
# individual slave address
address = 12
5.3 Schematic file
In this file the allocations between the data points are defined.
With the keyword value a value can be specified to represent the source data point value,
which is to be transmitted to the target data point.

UGW//micro Gateway
The keyword threshold depending on the data point type of the source data point has two
different meanings.
If the source data point is an analog value (data point type X or Y), then the specified value
has the effect of a threshold, which means that only changes in value where the change is
greater than the specified threshold are transferred.
If the source data point is an integer value (M or S) the target data point is changed only when
the value of the source data point is equal to the specified value.
5.4 Status LED
The gateway provides quick orientation of the current operational state via a three-color
status LED. The LED has the colors green and red and as a mixed color orange. During
system initialization, the LED lights up orange. After the initialization, the status LED flashes
green.
Table: status LED during normal operation

The data points determine the LED color code with ascending priority. The warning and error
parameters are set automatically by the gateway in accordance with the failure parameters.
The info parameter is available for the normal dispatch mechanism and may be used for
optical signalling of a collective defect, for example.

UGW//micro Gateway
7. FAQ
Problem: You want to access UGW//micro and do not know the IP address.
Solution 1
If your notebook PC is set as a DHCP client (the default), you can use the DHCP server of the
UGW//micro for providing an IP address. Press and hold the rest button of the UGW//micro
for at least 10 but not more than 15 seconds. If the status LED flashes green/red alternately,
the DHCP server is enabled.
Then connect the crossover network cable to your notebook PC and the IP address is
assigned automatically.
Crossover-cable
To access the configuration pages of the UGW//micro web server, launch your preferred web
browser and type the IP address 169.254.0.1 in the address field. Then enter your username
and password.
The default setting on delivery:
Username: gw
Password: GATEWAY
The password can be changed in the setup menu.
The home page of the UGW//micro is called up and displayed.

UGW//micro Gateway
Solution 2: (computer skills required and an installed BACnet protocol)
When BACnet is installed on the gateway (see sticker on the casing of the device) it can be
combined with the Wireshark (freeware, available at: http:// www.wireshark.org) to sniff the
network traffic and to read out on the basis of the reports.
Start by selecting the Wireshark program and choose Capture Options. Check the settings
in the next window and press the
Start button.
The capture – window will appear. Set the filter to bacnet. Then you start the UGW//micro
and wait for the output shown in the picture.
The IP address is shown below:
Source: 169.254.0.1 (in this example)
Network protocol: BACnet
Info: I-Am-Router-To-Network
Problem: You do not know the password to log on to the web console.
Solution: In this case, you can only revert the UGW//micro back to the factory settings.
!Attention!
In this case you will lose all settings and parameterizations of the UGW//micro

UGW//micro Gateway
To set the UGW//micro back to the default setting, press and hold the reset button for longer
than 15 seconds. The status LED flashes orange and after copying the factory configuration a
restart will be made.
Then the gateway should be reset to the default settings:
IP address 169.254.0.1
Username: gw
Password: GATEWAY
Problem: RS-485 connection problems
Solution: For RS485 connections if possible do not connect the GND, especially not between
switching cabinets with different GND - potentials.
Problem: A B RS485 cables reversed.
Solution: With swapped A B data lines a connection does not take place. The yellow LED
lights up constantly.
