Strategic Cooperation between Mitsubishi Electric Europe and Tixi.Com
Having analysed several vendors of industrial modems, Mitsubishi Electric decided to go with the one
who could offer the most advanced modem architecture, the most future-oriented product design and
the most appropriate product range: The Berlin based modem manufacturer Tixi.Com GmbH.
Tixi.Com Telecommunication Systems has become famous in the industrial market for its unique high
level modem functionality, easy configuration and direct communication with many PLC systems. One
of the most outstanding features of these intelligent modems however is, that the PLC programs do
not need to be changed at all in order to use all these new remote functions.
Mitsubishi Electric is starting to market a basic range of intelligent functions for fault messaging,
remote switching and remote control. Higher level functions, like data logging, embedded web server
and direct access via the web and other options like ISDN-modems, intelligent routers or memory
extensions may be offered later. In case of an earlier need of these options, especially in conjunction
with high-volume projects, the local Mitsubishi Electric representative will contact the European
Product Managers (M. Ginty, H. Voigt) for more information.
Mitsubishi Electric branded Tixi modems are exclusively sold by Mitsubishi Electric Europe B.V..
Modem Overview

Alarm Modem Features
1. Teleservice
The main customer need for modems today is to be able remotely access a PLC for maintenance.
But how does a service engineer know that he needs to check a remote PLC ?
Today he usually waits for the customer to phone him and tell him of irregularities.
The Alarm Modems can monitor PLC variables and send out message with actual PLC values
automatically when certain criteria are met.

PLC display (e.g. Alpha XL or HMI)
Example:
SMS
Reaction
“Password SetTemp 5 23”
Sets temperature in room no. 5 to 23° C
Remote Switching at no cost
Mobile phones usually display the number of the calling party when a call is arriving.
This feature can be utilized by the Mitsubishi Alarm Modem as a switching command thus avoiding the
telephone charges of a connected call or an SMS. Caller-ID recognition or CLIP is the usual term for
this feature.
Attention: Use of this features implies that the user will have to change his Alarm Modem
configuration each time different mobile phones or SIM cards will be used.
Acknowledgment of the Switch Command
The execution of the remote command may be acknowledged by SMS, fax, e-mail or Express E-Mail,
so the sender of the command may know shortly if the command was executed successfully or not.
Example:
Case
Acknowledgment SMS
If successful
Temperature in room no. 5 set to 23° C.
Site: weekend house in Berlin-Wannsee,
Device: MEE A/C 1234567. S/N: 98765432
If not successful

Current Status Query via SMS
In many service situations a quick check of the current status of a remote system is desirable.
Mobile phones are everywhere nowadays. A PC or laptop equipped with a mobile phone modem
(GSM) or with an analogue modem and a land line telephone jack may not be within easy reach.
The current status can easily be queried within less than a minute by sending an SMS to the Alarm
Modem. All that needs to be done for such a case is to define one or more “Send Status” commands
in the Alarm Editor by entering the important variables in a message template.
Example:
SMS
Reaction
“Password status”
The current values of all variables defined in the
command “status” are put into the predefined text
message and are sent off via SMS, fax or e-mail.
Return SMS:
Outside temp: -21°C
temp in room 5 (bathroom): 4° C
GSM signal: good.
Site: weekend house in Berlin-Wannsee,
Device: MEE A/C 1234567. S/N: 98765432
Checking the current status of a remote system can be done without a PC – just by using a mobile
phone.

Mitsubishi Alarm Editor
The Mitsubishi Alarm Editor is a simple to use Windows software (XP, 2000) for configuring many
functions of the Alarm Modems. You can fill in the address book with the contact details of the
recipients of the messages and the message template book, and you can define alarm event
conditions and remote switch commands. You can also establish a remote connection to a remote site
and then run your PLC programming software and monitor or reconfigure remote PLCs.
USP:
No AT commands required. - Never. Nowhere.
Example:

Sales Arguments
1. The Difference:
“Old” Modems ./. Intelligent Modems
1.1 Modem Technology is 25 years old !
Standard modems have not really changed in the past 25 years. They are still controlled by the very
same, simple commands that were used about 25 years ago. Such modems cannot send e-mails or
faxes by themselves – they always need a PC with communication software or a special, expensive
communications controller device. In the industrial electronics world there are no PCs – hence there is
no easy, cost efficient remote communication for PLCs.
1.2 Tixi Intelligent Modem Technology
The telecommunications specialist Tixi.Com in Berlin, Germany, has solved this huge problem in a
very convenient way by integrating all Internet and telecommunication functions and software right into
the modem itself.
A Tixi Modem is an intelligent communications controller featuring a powerful 32 Bit CPU, large Flash
memory and state-of-the-art Internet technology using an XML data base architecture.
Main features
• send and receive e-mail, fax, SMS, Express E-Mail
• optional Data Logging
• optional Web Server and communication with new web services (see page 22)
• Flash memory 2 MB, expandable to 66 MB
• Open interfaces for hardware and software developers
Modular hardware and software system.
1.3 Missing Link for PLC-Systems
In addition to the complete set of remote communication functions Mitsubishi Alarm Modems could be
able to support more than 25 native PLC and Fieldbus protocols.
Mitsubishi Alarm Modems work as multi-lingual interpreters between PLCs and
“the outside” world of remote communication and the Internet.
A PLC does not need to “know” anything about Internet and remote communication.
Using Mitsubishi Alarm Modems there is no need to change any bit in your PLC program as the MAM
“understands” your PLC and can read and write PLC variables and I/O-ports like your programming
software can.
Intelligent functions can be configured with an easy to use Windows program, the Alarm Editor.
– Old cryptic AT-commands are not needed anymore (but do work with Mitsubishi Alarm Modems.)

2. New Business:
Teleservice for PLCs
700 million PCs worldwide use Internet and telecommunication.
But PLCs still have no connection to the “outside” world.
Mitsubishi Alarm Modems open remote communication to the PLC world
with the Tixi modem system that is not unlikely to become a new modem standard for PLCs.

Competitor Analysis
Main international competitors in the field of standard industry modems are
•
•
•
Westermo
industrial quality GSM and analogue modems
Siemens
GSM modems only
Sony-Ericsson GSM modems only
These modems have no special intelligence nor functions other than SMS sending and receiving in
GSM-modems using AT-commands.
Regional players with market shares mainly in Germany are:
•
Insys
similar to Westermo modems
10 SMSes can be stored and triggered via I/O ports.
One modem type supports some communication with Siemens Logo!
No other PLCs supported.
•
ICON AG
High level remote control system with a few 6 I/Os for building automation.
Supports EIB, a web cam, data logging etc.
No PLC protocols.
Is OEMed by some companies, i.e. ABB, Merten.
•
LUCOM
modem with data logger
A detailed comparison is attached as appendix:
• GSM modem comparison
Appendix B
• Analogue modem comparison Appendix C
Summary of the comparison
No other modem offers such an advanced set of automatic communication functions.
No other modem offers PLC and field bus protocols like the new Alarm Modems.
The ICON AG ic.1 Controller comes closest to Alarm Modems.
Customer says: “Modem Xyz has the same features as the Alarm Modem.”
Do ask the customer for details of features like: e-mail, fax, alarming, remote switching, memory type
and size, logging and – above all – pricing, model number and manufacturer. Mostly, the customer
will not know these data “exactly” and will “give up” if you insist there is no other modem on the market
(except Tixi.Com Alarm Modems).
Some standard modem makers, e.g. Insys, advertise their modems can send e-mails. This is not true.
Their modems can send an SMS to an SMS service center which can convert an SMS-text into a very
short e-mail of 160 characters less the e-mail address. Only ICON AG and Lucom controllers support
real e-mailing like Alarm Modems.
With the new Alarm Modem family Mitsubishi Electric will take the leadership in the PLC market for
remote communication.

Special Features
Networking PLCs
Alarm Modems with an RS485 interface are able to access networked PLC. They can address each
individual station and access data (variables, ports etc.) of each individual PLC via the Mitsubishi
Multi-Drop protocol (or Format1 protocol):
Example:
MAM-M24
1x RS 232
1x RS485/422
20 Alarms
RS485
Alarming Schedule - the Multi-Level Alarm Plan
Up to 3 freely definable alarm levels may be configured.
Example:
The Mitsubishi Alarm Modem monitors the variables and
ports in a PLC.
Alarm Level 1:
In the event of a fault being detected, MAM sends an
SMS to service technician A.
If this person acknowledges receipt within a predefined
time (e.g. 10 minutes), MAM resets the alarm.
Alarm Level 2
If MAM does not receive the acknowledgment within the
pre-defined time, it starts alarm level 2 and sends
several messages to other destinations:
•
An SMS to service technician B,
•
a fax to the service center,
•
an e-mail to the owner of the equipment and
one to the archive data base on the web.
Alarm Level 3
If technician B does not acknowledge receipt within a
defined time, MAM initiates the next alarm level.
Express E-Mail = E-mail via Phone Lines
Send an e-mail to a PLC ?
No delivery available.
Impossible. Internet e-mail is not delivered but must be retrieved from an Internet mail server.
The e-mail may never arrive since the Alarm Modem connected to the PLC does “know” if and when
to pickup e-mail. Thus the runtime of e-mails is completely uncertain – unless the recipient is
permanently connected to the Internet or connects at regular intervals.
Send an Express E-Mail to the PLC !
Direct, immediate delivery.
Express E-Mail is direct e-mail via phone lines without the Internet.

IP Systèmes, importateur/distributeur des solutions d'automation de MITSUBISHI ELECTRIC en France Tel : 0820 200 290 (15cts/min)
Although very similar to Internet e-mail, its destination address consists of a user name and an
international telephone number with country code, area code and local phone number.
Communicating via the telephone network has several advantages: fast, i.e. immediate transmission,
confidential and secure transmission, immediate confirmation of delivery (like faxing.)
Direct data link between PLCs using Express E-Mail
Express E-Mail can be used to transfer data from one PLC to another PLC and vice versa:
• regularly
(e.g. once every hour) or
• upon an event (e.g. triggered by PLC marker or input)
Any type of variables can be “mapped” (automatically updated) between:
• PLCs of the same type
• PLCs of different types, same manufacturer
• PLCs of different manufacturers (if protocol is supported by Alarm Modem).

Modems for remote maintenance and teleservices are a good choice especially for all those small and
de-centralised devices and stations, which are
mostly situated at locations without any telecommunications and network infrastructure, e.g.:
•
•
•
•
•
•
•
•
•
•
•
•
•
Heating systems
Air conditioning systems
Pumping stations
Tanks
Weather stations
Cooling systems
Containers
Drives/Frequency converters
Vehicles
Meters for
Gas, water, electricity, heat
Industrial controllers
PLCs
Measuring devices
(data loggers, sensors)
Zentrale
On-site services are cost-intensive
All these devices have to be installed, configured and maintained. These services are cost intensive.
Remote maintenance can help to reduce these costs dramatically, e.g. by saving travel time and
expenses.

Alarm Modem Technology
No More AT Commands – XML Modems for the Future
Today's “standard” modems are still controlled by the very same primitive AT commands that were
used 25 years ago! This has been a tremendous obstacle in to telecommunication and Internet
communication in industrial electronics.
The Alarm Modem Modem System is based on a powerful 32-bit RISC CPU and the TECom highlevel remote communication system, which is configured using state-of-the-art XML technology.
Example of address book entries:
<AddressBook>
<Meyer>
<EMail
_="Meyer@Firm.de"/>
<SMS_No _="+49-174-1234567"/>
<SMS_Provider
_="D2"/>
<Fax
_="+49-89-1234567"/>
<Express _="Meyer+49-89-1234580"/>
</Meyer>
<Schneider>
<SMS_No _="+49-171-9876541"/>
<SMS_Provider
_="D1"/>
</Schneider>
</AddressBook>
The message definition contains references for
the recipient in the address book, and to a
template in the text database (User Templates)
for the message text. This template in turn
contains a reference to particular site information. This example shows the highly flexible
and future-oriented approach that XML offers
for configuring the Alarm Modems. It can also
be used for the later configuration of alarm
devices via the Internet (just imagine what this
task would be like using AT commands!).
Message template with variable
installation and site information:
<UserTemplates>
<AlarmMsg30>
<L _="Room temperature too high."/>
<L _="Act. Temp.: {Temperature} °C"/>
<Include ="/D/UserTemplates/SiteInfo"/>
</AlarmMsg30>
<SiteInfo>
<L _="Installation: Super AC type 13"/>
<L _="Building: Reichstag,R.2001"/>
<L _="Site: Berlin, Germany"/>
</SiteInfo>
</UserTemplates>

TiXML Achitecture and Alarm Modem Job System
Core of the Alarm Modem system architecture is an Event Handling system processing all external
and internal event states. Events can be triggered by integrated variables (I/Os) and external variables
referring to PLC markers or variables. The scheme below shows the main function blocks of the
system architecture.

Internet Capabilities of the Alarm Modems
1. Embedded Web Server (option)
The embedded web server can be connected with any standard
web browser and can be used to
• visualize the status of PLC variables or I/O ports
• call-off log data (system or customised log)
• remotely switch variables or ports by mouse click (or to
assign values to variables)
To access the Alarm Modem’s web server a dial-up connection
to the Alarm Modem has to be established.
2. Smart Internet Service to access websites
held in an Alarm Modem
The Internet is designed for dial-up connections primarily.
But how to get out of the Internet to access devices?
Tixi operates a web service to get internet access to devices
in the field using dial-out facilities:
www.devicecontrolweb.com.
For details please refer to appendix D.
3. Dedicated web database for log data
collected from de-centralised devices
This portal
• can handle log data stored in an SQL database
• creates reports on selected variables for given
period
• hold machine data (location, set-up date, last
inspection…) for various types of devices and
locations
• has a built-in rule-based messaging function
Any number of devices and of users can be administered.
Only an Internet connection is required to access it.
For details please contact EBG, Mr. Voigt or Mr. Ginty.

Future Options of Alarm Modems
•
•
•
Data Logging for single or multiple stations over field bus network with up to 100 data points
Embedded web server
Direct Access over the Web from any PC with any Internet connection
Future modem models
• Alarm Modem GPRS
• Alarm Modem ISDN
• Alarm Modem Ethernet
• Analog and GSM Router Modems
Other PLCs and Fieldbuses
One of the Unique Selling Points (USPs) of Mitsubishi Alarm Modems is that they talk to PLCs in the
respective PLC-language. This way Alarm Modems understand various Mitsubishi controllers, but
many other ones as well (upon request):
•
•
•
•
•
•
Siemens Simatic S7-200
Moeller Easy 400 - 800, MFD-Titan, PS4
ABB AC010, AC31
VIPA 100, 200, 300V
Saia Burgess PCD1, PCD2
Allen Bradley PICO
Fieldbus
• Modbus RTU and ASCII
• M-Bus
• CAN Bus (2005 Q4)
Attention:
Non-Mitsubishi PLC protocols will not be supported by Mitsubishi.
Translator PLC1 to PLC2
Alarm Modems support two different PLC-protocols simultaneously and may thus work as a translator
between two totally different PLC systems for exchanging data locally via two serial ports or remotely
via SMS, Internet e-mail or Express E-Mail. This features needs special configuration in TiXML and
therefore should only be offered in important business cases.
