1Alarm Modems At A Glance
Tixi Alarm Modems are new automatic modems with a large data memory, several functions and
integrated Internet technology. They are designed as intelligent communication computers with a 32-
bit power CPU and a 2 MB non-volatile Flash memory. This can be expanded by up to 64 MB, thus
providing enough space for your data requirements now and in the future.
Tixi Alarm Modems are fully automatic and can
• send alarm and status messages via SMS, Express E-Mail, E-mail or fax
• receive switch commands via SMS or Express E-Mail and forward them to a PLC,
• send the data of a connected PLC/system,
• exchange data between PLC/systems
What's more:
• You can use them as "normal" modems for the remote access of PLCs or systems, and the
programming software of the PLC can generally be used for this.
1.1 State-Of-The-Art Communication
The Tixi Alarm Modem can communicate directly with the PLCs of several manufacturers using the
relevant PLC protocol. Different bus systems are also supported. User-friendly XML-based software
programs enable the required functions to be configured easily. The over twenty-year-old history of
modems being controlled by primitive AT commands can now be forgotten at last.
The wide range of features available on the Tixi Alarm Modems provide solutions for a number of
applications such as the monitoring of temperature, pressures, levels, or the activation of motors,
fans, pumps, slide valves and flaps.
1.2 Easy to retrofit
Tixi Alarm Modems can be integrated in existing systems with a minimum of effort. The
communication protocols of commonly used PLCs are already implemented and so modifications to
the PLC program are normally not required.
6

2Function Overview
2.1 Integrated PLC Protocols
Tixi Alarm Modems can communicate directly with the PLCs of leading manufacturers using the
relevant PLC protocol, and access PLC variables, markers and ports via the PLC programming
interface. This can be achieved without having to adapt the PLC program or load a special function
block for communication.
These protocols are supported:
• ABB
• Allen Bradley
• Berthel
• Carel
• Tixi
• Modbus
• Moeller
• SAIA
• Siemens
• Tixibus
• VIPA
OEM Protocols
Manufacturers (OEM) and customers with special PLCs may take advantage of one of these options:
• Common access to Modbus industrial standard or to the TixiBus protocol
• Tixi.Com implements the appropriate protocol into the Tixi Alarm Modems.
2.2 Alarm Notification with Confirmation
Tixi Alarm Modems are fully automatic and can send status and fault messages to any recipient via
SMS, fax, E-mail or Express E-Mail. Messages can be triggered by PLC variables.
Address book:
The SMS, fax and E-mail addresses (max. 100) are managed in an address book.
Messages:
The message texts (max. 100) can contain up to 100 actual values from the PLC and can be of
any required length when used with faxes and E-mails.
Alarms:
Up to 100 alarms and actions such as switching commands can be defined.
Alarm cascade and acknowledgments:
Any number of freely definable alarm levels can be set up if message acknowledgment is
required. If a message is not acknowledged within a specified time, other recipients can be
notified. This can be cascaded as required.
2.3 Remote switching via SMS and Express-E-Mail
A short command via SMS or Express E-Mail can switch the optional outputs of the Tixi Alarm Modem
and those of a connected PLC. PLC variables can also be set in this way.
The execution of the command can also be acknowledged. 100 SMS switch commands with up to 10
parameters each can be defined as required. PLC variables can be queried simply and quickly by
SMS command without the need for a PC.

2.4 PLC Data Logging
Tixi Alarm Modems may record any PLC data (variables, ports) and system data with timestamp
inside the non-volatile Flash memory (2 MB - 66 MB). The poll cycle may be adjusted at will, as well
as the extent of data being logged.
The logged data is sent as XML text file or as Excel-compliant CSV via E-mail, Express E-Mail or Fax.
This may be triggered periodically via scheduler, or by a specific event occuring. There may be
several logfiles in use at the same time. The memory acts as a ring buffer.
2.5 Teleservice via PC
A Tixi Alarm Modem can be used to handle the remote maintenance of several controllers via a
telephone line. This is usually possible with the programming software in use. The variables and I/O
ports of the PLC can also be read or written remotely with the Tixi Alarm Editor (TILA). The entire
configuration of the Tixi Alarm Modem can be carried out by remote dial-in and the logged data can
be read “manually".
Secure Login
Optimum security is ensured since unauthorized dial-in attempts are prevented by means of a
login procedure with user name and password. All dial-in attempts are recorded.
2.6 Web Server inside the Tixi Alarm Modem
Web server functionality is implemented inside the Tixi Alarm Modem, so any web browser may be
used to visualize facility status, PLC data and logfiles respective alter these by mouse click.
For that purpose, merely some HTML pages need to lodge inside the modem. Access is done via
telephone network. Static IP addresses are not necessary.
2.7 Web Portal with Database and Facility Record
A variety of PLC systems and Tixi Alarm Modems may me administered by means of a SQL
database. Logged data may be stored, analyzed and visualized here.
Authorized users only are granted access to these data. The database may be adapted to custom
needs with ease and is open to other systems as well.

2.8 Pump alarm application example
The following example shows how you can use the wide range of functions of the Tixi Alarm Modem
to handle complex tasks automatically:
Pump alarm:
• Send an E-mail, a fax and an SMS to three different destinations
if input 312 on the PLC closes.
• Wait 10 minutes for a confirmation via SMS.
Service technicians can query status values by SMS (or dial-in and PC).
• Wait for a switching command for pump 2.
• If the SMS confirmation does not come in 10 minutes,
start a new alarm message cascade to other recipients.
• If the switch command for switching on the reserve pump has been received,
switch on the PLC output 17 (or a relay).
• After 5 minutes, send a status message via SMS and E-mail if pump 2 is running or not.
• If not so, send SMS, fax and E-mail to fire brigade and others. Send an alarm notification to a
web-based SQL database.
• Send the last 72 hours logged data as Excel-compliant CSV file to two E-mail recipients or to a
web-based SQL database.

4Sending SMS in a land-line network
The land-line SMS network makes it possible to also send an alarm message as an SMS message
from an analog modem to mobile and land-line numbers. It is only necessary to select SMS providers
that offer special service centres for this feature.
4.1 Sending SMS to the land-line network
The option of sending SMS messages to the land-line network has up to now only been available
from Deutsche Telekom and the SMS provider Anny Way.
The phone numbers for these SMSCs are as follows:
• Deutsche Telekom: [phone]
• AnnyWay: [phone]
The following requirements must be fulfilled in order to send an SMS to a land-line network:
• The call number identification (CLIP) function for incoming calls must be activated. (Telekom
service feature CLIP activated.)
• For Deutsche Telekom lines: The land-line connection of the Tixi Alarm Modem must be
registered daily at the SMS service centre as SMS-compatible.
• The terminal device must be SMS compatible.
• The telephone provider must offer the "Land-line SMS" feature.
The sender and the recipient must use the same SMSC (such as Deutsche Telekom or Anny Way) so
that the SMS can be received as a text message. Otherwise it will be converted to a voice mail.
Messages can be sent via the land-line network using both SMSCs.
NOTE:
• As land-line SMS is a relatively new service of the Deutsche Telekom, it may be subject to
modifications and additions. The latest information on the subject can be found at
http://www.sms-im-festnetz.de.
• If you are using a different telephone supplier than Deutsche Telekom AG, you should ask
your supplier which land-line SMS features are supported on your line. The full range of SMS
features provided by the Tixi Alarm modem is currently only supported by lines switched by
Deutsche Telekom AG in the local network.
• In case the requirements for SMS operation in the fixed network aren't met, mobile phone
gateways may be utilized, too. This procedure is described within the next chapter.

12
4.2 Sending SMS to the mobile network
Land-line SMS messages can be sent via the Tixi Alarm Modem to a mobile device (such as mobile
phone or GSM modem) using the SMS service centre of the mobile network supplier. The use of this
SMS service is activated by dialling the appropriate phone number of the SMS service centre. The
phone numbers of different SMS service centres are already stored in the Tixi Alarm Modem. You
simply assign the required supplier to the address entry of the recipient.
The following phone numbers of SMS service centres are used in Germany:
• D1: [phone]
• D2: [phone]
• Eplus: [phone]
In Austria, this SMS service centre is to be used:
• Mobilcom Austria: [phone]
The selection list can be expanded at any time. Refer to the TILA and TICO manuals for further
information, as well as to the service section of our website.
NOTE:
• The above list of suppliers is not complete and some phone numbers may be subject to
change. Binding information can be obtained by the mobile network supplier concerned.
• Your selection of SMS service centre should take into account the costs involved (such as for
roaming) in addition to the range of supported mobile networks.
• The SMS service centres noted above may be used by all fixed network connections in
Germany. Hence, they can be used even by those who got a fixed network connection that
supports fixed-network-SMS, according to chapter Fehler! Verweisquelle konnte nicht
gefunden werden. of this manual.

DANGER:
• The device must only be used in rooms that are dry and clean. Protect the device
from humidity, water splashes or heat.
• The device must not be used in environments containing flammable gases, fumes or
dust.
• Do not subject the device to shock or severe vibration.
15

5.5 Connecting to the Telephone Network
16
elephone
Connection to the telephone network is established by means of the (provided) t
cable and the jack labeled "Line".
The Tixi Alarm Modem utilizes the a/b lines (as shown in adjoining figure). In case that
futher extensions are connected parallely to the same TAE jack, these will become
deactivated.
5.5.1 Testing the Telephone Connection
In order to check the telephone number of the telephone connection used, initially connect a
telephone set (A) to this connection. Now, use another telephone set (B) and dial the telephone
number of connection (A). If the telephone set (A) rings, the number used is correct. Alternatively, the
number of connection (A) may be identified by dialing the number of telephone set (B) from the
connection (A). In case that connection (A) supports calling line recognition (CLIR), telephone set (B)
will ring and display the number of connection (A).
If caölls in both direction are successful, connect the Tixi Alarm Modem to the appropriate telephone
connection. Now, the Tixi Alarm Modem may accept calls, receive messages and may trigger certain
actions by identifying the calling telephone number.
5.5.2 Calling Line Identification: CLIP
In order to trigger actions by means of the number of an incoming call, the telephone connection used
must be able to recognize these numbers. This is done via the CLIP feature, which you can apply for
at your telephone provider.
5.5.3 Connection to a PABX
When connectiong the Tixi Alarm Modem to a PABX, watch the dial prefixes if need be. Additionally,
make sure the PABX supports the CLIP feature if you want to use the related Tixi features.
In case that SMS shall be received via the PABX, it must support the "fixed-network-SMS" feature.

The 9-pole RS232 interface COM2 (plug) can be used for
connecting a PLC directly and has the same assignment as
the standard RS232 interface of a PC.
Tixi.Com offers several adapters to use with the RS232 interface. Detailed information on these
adapters can be found in chapter Fehler! Verweisquelle konnte nicht gefunden werden. of this
manual.
NOTE:
• As most PLCs require the use of a special serial programming cable, the programming cable
of the PLC manufacturer should be used in all cases.
• Details on how to connect each PLC can be found in chapter Fehler! Verweisquelle konnte
nicht gefunden werden. of this manual.
6.3 COM2 - RS485 / RS422
The HM4x series of Tixi Alarm Modems is equipped with a RS485/422 inteface in order to connect 2-
and 4-wire bus systems. This interface is implemented as a 5 pin screw terminal, which is not
galvanically insulated.
Assignment of the RS485/422, viewed from above.
NOTE:
• We recommend using "Twisted-Pair" cables. For RS422 and 4-wire RS485, two twisted pair
cables are to be used.
17

RS422 Connection
The Receiving Lines are to be connected to
R+ (remote: T+) and
R- (remote: T-),
the Sending Lines to
T+ (remote: R+) and
T- (remote: R-)
according to adjacent figure.
6.3.1 Accessing the DIP Switches
In order to set the operating mode of the RS485/422 interface, DIP switches are to be used. These
are located right beneath the COM2 interface and may be accessed after removing the terminal
cover:
Put a srew driver (with 3 mm blade) into the slit between case and terminal
cover and rotate the screw driver a little bit.
With an audible click, the terminal cover snaps out of the case and may be
removed now.
Below this cover, you will find the DIP switches. Their
exact meaning is described in the following table.
18

19
6.3.2 Setting operating mode via the DIP switches
Operating mode Switch 1 Switch 2 Switch 3 Switch 4 DIP
2-wire RS485 with termination 1 1 1 1 1111
2-wire RS485 w/o termination 0 0 1 1 0011
4-wire RS485 w/o termination 0 0 0 0 0000
4-wire RS485 with termination 1 1 0 0 1100
RS422 0 0 0 0 0000
NOTE:
• RS485 stipulates that the cables should be terminated at both ends of the transmission
section. The termination prevents signal reflections in the cables and in times of no data
transmission enforces a defined idle state on the bus.
• This termination can be implemented using, for example, specific resistors at the screw
terminal. This can also be implemented via the DIP switches on theTixi Alarm Modem.

6.3.3 RS485 2-wire connection
In this operating mode, transmit cables and receive cables are interconnected. If the Tixi Alarm
Modem is installed at the beginning (first station) or end (last station) of the bus system, the bus
system must be terminated by setting the DIP switches accordingly.
The twisted pair cable is to be connected to
T+ to T+ or R+ and for
T- to T- or R-
according to the adjacent figure.
6.3.4 RS485 4-wire connection
The terminals of the 2 twisted-pair cables are wired in the same way as for the RS422 connection.
Both twisted-pair cables must be terminated if the Tixi Alarm Modem is installed at the start or end of
the bus cables. The termination of the receive cables is activated via the DIP switches. The transmit
cables must be terminated externally (see figure, arrow).
The twisted pair cables are to be connected
according to the adjacent figure.
For termination of the sending line, put a
resistor (120 Ohm/0,5 W) between the T+ and
T- terminals.
ATTENTION:
Always ensure that the end devices are terminated correctly.
Incorrect or missing termination may give rise to communication faults.
