1Mitsubishi Alarm Modems at a Glance
Mitsubishi Alarm Modems are new automatic modems with a large data memory, several func
tions and integrated Internet technology. They are designed as intelligent communication com
puters with a 32-bit power CPU and a 2 MB non-volatile Flash memory. This can now be
expanded by up to 64 MB, thus providing enough space for your data requirements now and in
the future.
Mitsubishi Alarm Modems are fully automatic and can
send alarm and status messages via SMS or Express E-Mail,
쎲
receive switch commands via SMS or Express E-Mail and forward them to a PLC,
쎲
send the data of a connected PLC/system,
쎲
transfer data between PLCs
쎲
What´s more:
You can use them as “normal” modems for the remote access of PLCs or systems, and the
쎲
programming software of the PLC can generally be used for this.
1.1State-Of-The-Art Communication
The Mitsubishi Alarm Modem can communicate directly with the Mitsubishi PLCs using the relevant
PLC protocol. Modbus RTU and Modbus ASCII are also supported. User-friendly XML-based software programs enable the required functions to be configured easily. The over twenty year history of
modems being controlled by primitive AT commands can now be forgotten at last.
The wide range of functions available on the Mitsubishi 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.

Mitsubishi Alarm Modem1-1
Integrated PLC protocolsFunction overview
2Function overview
2.1Integrated PLC protocols
Mitsubishi 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 pro
gramming interface. This can be achieved without having to adapt the PLC program or load a
special function block for communication.
These protocols are supported:
Mitsubishi Alpha XL
쎲
Mitsubishi MELSEC FX1S/FX1N and FX2N/FX2NC
쎲
Mitsubishi System Q (in preperation)
쎲
-
2.2Alarming with acknowledgment
Mitsubishi Alarm Modems are fully automatic and can send status and fault mes
sages 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) cancontain up to100 actual
values from the PLC and can be of any required length
when used with faxes and e-mails.
Alarms:Up to 100alarms and actionssuch 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, one or several
recipients can be notified. This can be cascaded
as required.
-
2.3Remote switching via SMS and Express-E-Mail
A short command via SMS or Express E-Mail can switch the optional outputs of
the Mitsubishi 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.
2-1MITSUBISHI ELECTRIC
Function overviewTeleservice via PC
2.4Teleservice via PC
A Mitsubishi Alarm Modem can be used to handle the remote maintenance of
several controllers via a telephone line. Thisis usually possible with the program
ming software in use. The variables and I/O ports of the PLC can also be read or
written remotely online with the Mitsubishi Alarm Editor (MX-AME). The entire
configuration of the Mitsubishi 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 and dial-in attempts are recorded.
2.5Pump alarm application example
The following example shows how you can use the wide range of functions of the Mitsubishi
Alarm Modem to handle complex tasks automatically:
Pump alarm:
햲
Send an e-mail, a fax and an SMS to three different destinations
if input X0 on the PLC closes.
햳
Wait ten minutes for a confirmation via SMS.
Service technicians can query status values by SMS (or dial-in and PC).
햴
Wait for a switch command for reserve pump 2.
햵
If the SMS confirmation does not come within 10 minutes,
start a new alarm message cascade to other recipients.
햶
If the switch command for switching on the reserve pump has been received,
switch on the PLC output Y10 (or a relay).
2.6Model And Equipment Versions
The Mitsubishi Alarm Modems were offered in two equipment versions: GM series (Alarm
Modem GSM) and AM series (Alarm Modem 56k ). The basic functions within these series are
identical.

tion. Both twisted-pair cables must be terminated if the Mitsubishi 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).

6Operation
Once all installation steps have been completed, you can start operating the Mitsubishi Alarm
Modem.
Self-test after power up
The Mitsubishi Alarm Modem carries out an extensive self-test after the power supply is
switched on. All the LEDs will switch on for test purposes and all three types of memory are
checked. The memory test is also carried out automatically with every power up.
Memory test
This tests the internal memory with RAM, program memory (Flash ROM) and the file system in
the user memory (Flash). On basic models (2 MB for the user memory) this test lasts approx. 12
seconds. If memory expansions have been fitted, the time can be considerably longer depend
ing on the size of memory in use.

NOTE
If the Mitsubishi Alarm Modem is being commissioned for the first time or after a complete
delete operation (Factory Reset, section 10.2.3), a project must be loaded with the correct
PIN for the SIM card. Note the following instructions in section 7.1 (Initial configuration).
6-2MITSUBISHI ELECTRIC
Configuration and projectsInitial configuration
7Configuration and projects
7.1Initial configuration
You can regard a Mitsubishi Alarm Modem (MAM) in the same way as you would consider a PC
with an operating system and many communication programs. After the initialpower up, the task
memory is empty and the MAM “doesn’t know” what it is meant to do. It has to be configured first
of all and assigned a task. The task definition for the MAM with all the relevant data is called a
project and is saved in a TiXML project file. These points are explained in the following para
graphs.
7.2Loading projects in the MAM
You can create projects with a number of different user programs available, e.g. MX-Mitsubishi
Alarm Editor MX-MAE (see chapter 8.1). The required parameters can be entered easily on the
PC and then saved on the hard disk of the PC as a TiXML project file. The PIN of the SIM card is
also entered in the software and in the project file (only GM series). The project must then be
loaded onto the Mitsubishi Alarm Modem via a serial interface.
-
The device is now functional as a stand-alone device (i.e. without a PC) and can be used, for
example, to monitor PLCs.
7.3Loading projects remotely on the MAM
Once a functional configuration has been loaded on the MAM, this can also be modified or transferred by remote dial-in. Every reconfiguration (remotely or locally) can be protected from unauthorized access by means of a password and user name. Refer to section 8.2, Secure Login, for
further information.
NOTEThe contents of chapter 7.4 applies only to the GM series.
7.4Operating the GSM Modem
As with a mobile phone, the PIN of the SIM card has to be entered in order to correctly configure
the Mitsubishi Alarm Modem for GSM operation. The MAM can only log in automatically and
become functional if the correct PIN has been entered. Refer to the documentation of your
mobile network supplier for thePIN. Once the SIM card has been inserted in amobile phone, the
PIN can also be modified there.
7.4.1PIN entry with MX-MAE software
When using MX-MAE software, the PIN can be entered when you are creating the project.
7.4.2PIN OK, network available, MAM logged in
The MAM logs in like a normal mobile phone if the PIN that is entered in the project for the SIM
card inserted is correct, and network reception for the respective provider is available. The Line
LED will then flash at regular intervals.
Mitsubishi Alarm Modem7-1
Operating the GSM ModemConfiguration and projects
7.4.3PIN OK, no network, MAM not logged in
The MAM cannot be logged in if there is no network reception available for the provider con
cerned, even if the PIN that has been entered in the project for the inserted SIM card is correct.
The Line LED will not flash and will remain off.
The Line LED will flash again, if the reception quality is sufficient, by using a stronger antenna for
example.
7.4.4PIN incorrect, MAM not logged in
If the PIN that has been entered in the project for the inserted SIM is incorrect, the MAM will not
be able tolog in, and will indicate thisby causing theProcess, Line andMail-out LEDs toflash.
The same will happen if after initial commissioning or after a factory reset no project and there
fore no PIN is loaded onto the MAM.
Ensure that avalid SIM card was inserted, thatit is seatedcorrectly and thePIN used iscorrect.
7.4.5SIM card disabled, entry of the SUPER PIN
If the PIN was entered incorrectly 3x,the SIM card will be disabled. The card can be unlocked
again by entering the SUPER PIN. To do this, insert the disabled SIM card into a mobile phone
and enter the SUPER PIN and PIN as described in the operating instructions. Once the mobile
phone has logged in properly with the SIM card, the unlocked SIM card can then be reinserted in
the Mitsubishi Alarm Modem.
-
-
7.4.6SIM Card Service Center
Additionally, use a mobile phone to check if the SMSC (Short Message Service Center) number
ist stored on the SIM card. If not so, sending SMS from the Mitsubishi Alarm Modem will not be
possible. In that case, contact your mobile service provider for details on how to store this number on the SIM card.
7.4.7Caution in border regions: Logging in abroad
Like a mobile phone, the MAM also searches for the strongest mobile network provider in the
area. In areas up to 10 kilometers from international borders, thismay be a foreign mobile phone
provider. Considerably higher costs may be incurred if the MAM logs into one of these (roam
ing). Moreover, problems may also occur with the sending of SMS messages and e-mails. You
can prevent thelogging into “foreign”networks by allocating a “home network” to the SIMcard.
-
7-2MITSUBISHI ELECTRIC
Configuration and projectsOperating modes: Modem Mode and TiXML Mode
7.5Operating modes: Modem Mode and TiXML Mode
TiXML Modus
Mitsubishi Alarm Modems (MAM) can handle a wide range of tasks automatically. These tasks
are written and configured in TiXML, a variant of the XML standard. This operating mode is
called TiXML Mode.
7.5.1Alarm Editor MX-MAE activates the correct mode
If you always configure the Mitsubishi Alarm Modem with the MX-MAE software, you do not
have to worry about the two modes, as this tool will automatically activate the correct mode
(TiXML Mode). You can skip the rest of this section and continue reading at the chapter 8
"Software".
7.5.2Using MAM without MX-MAE
Only if you are using the MAM without MX-MAE, for example:
because you wish to use the MAM for other programs just as a simple modem,
쎲
or
because you wish to work with a terminal program such as Windows Hyperterminal,
쎲
or
쎲 because you are programming a PLC that is required to send commands to the MAM,
you will have to take the difference between TiXML Mode andModem Mode into account.
7.5.3TiXML Mode
The task definition for TiXML Mode is loaded on the MAM by means of a project file (the configuration file). These kinds of projects can be created with different software tools (e.g. MX-MAE).
MX-MAE will automatically switch a MAM to the correct mode, i.e. TiXML Mode. The user does
not have to worry about this.
After power on a MAM will always be in the last activated mode (TiXML Mode or Modem Mode).
The device can be set to the TiXML Mode with a factory reset (refer to section 10.2.3) so that it
can immediately start with the automatic tasks, e.g. send alarms in the event of faults.
7.5.4Modem Mode (also AT mode)
Normal modems (AT modems) can do nothing “on their own” and are controlled by means of
simple communication commands, e.g.:
쎲
“Dial a telephone number and connect me” and
쎲
“Terminate the connection and hang up.”
These modems always require a PC or a communication controller that executes the tasks
since they have no “intelligence” of their own and do not recognize any Internet protocols.
For greater compatibility, however, Mitsubishi Alarm Modems can also be switched to operating
like a normal AT modem. This is called Modem Mode, in which the red Mode LED will be lit.
PIN entry without MX-MAE (only GM series)
If you are not using MX-MAE, you must enter the PIN or SUPER PIN with TiXML or AT com
mands by means of a terminal program. Therefore refer to the TiXML manual.

Operating modes: Modem Mode and TiXML ModeConfiguration and projects
7.5.5Activating/deactivating Modem Mode
In Modem Mode, a MAM operates like a normal modem and establishes connections with the
conventional AT command: “ATDT 0123456789”.
The MAM must, however, be switched beforehand from TiXML Mode to Modem Mode.
Activating Modem Mode
The following TiXML command can be used to switch the device to Modem Mode via COM1:
AT+TMode="ModemMode"
The device will send back the following acknowledgment:
OK
Once this command has been sent, the MAMwill only recognize AT commands and will respond
to these, for example, with OK.
Deactivating Modem Mode, activating TiXML Mode
If the device is in Modem Mode, it can be switched back to TiXML Mode using the following
AT command:
AT+T Mode="TiXMLMode"
Response from MAM:
OK
Once this command has been sent, the MAM will only recognize TiXML commands and no
AT commands.
ATTENTION:
The MAM cannot send or receive messages if the red Modem Mode LED is lit. Alt-
E
NOTEAT commands are only processed by Mitsubishi Alarm Modems in Modem Mode.
hough the MAM will continue processing the tasks, message jobs cannot be execu
ted until the modem is free again and the Modem Mode LED is off.
TiXML commands are only recognized in TiXML Mode.
7.5.6Sending commands to the MAM
Any terminal program, such as Windows Hyperterminal, can normally be used for entering and
transferring TiXML and AT commands.

8.1MX Mitsubishi Alarm Editor MX-MAE
MX-MAE is auser-friendly Windows software for configuring MAM functions such as alarms and
messages, as well as the reception/sending of messages and the reading of logged data.
You use the mouse to configure the recipients, messages and PLC variables for alarm mes
sages. MX-MAE also allows you to dial into a remote MAM from a PC via a modem, fixed net
work or mobile phone connection and to configure it remotely.
In this way, MX-MAE allows you to access aremote device exactly as if it was a local device, and
with the same range of functions.

8.2Secure Login: Access Protection
Mitsubishi Alarm Modems can be protected against unauthorized access. To do this, the names
and passwords of authorized users are defined in the software tool(MX-MAE) during the config
uration. In this way, only authorized users are able to modify or read the MAM configuration or
access the Mitsubishi Alarm Modem locally or remotely.
If the SecureLogin data is“forgotten”, the device must undergo a factory reset and restored toits
original default settings. This is the only way to delete the entire configuration that also contains
the Login-Data (see section 10.2.3). The MAM must then be reconfigured with a project and a
Secure Login.

Remote AccessSoftware
8.3Remote Access
If you are using a PLC programming software to configure and control your PLC, you can also
make use of its functions remotely by software MX-MAE. To do this, the PLC must be connected
to a serial interface on the MAM.
MX-MAE establishes a connection to the remote Mitsubishi Alarm Modem and uses its RS232
interface to the PLC as a virtual local COM interface for your PC. This transparent modem con
nection allows you to access your PLC using your standard software as if it was connected
directly to your PC. You can then carry out any required task remotely.

Communication with a PLCPLC driver in the Mitsubishi Alarm Modem
9Communication with a PLC
Mitsubishi Alarm Modems can communicate with a PLC in two different ways:
The Mitsubishi Alarm Modem can speak the language of your PLC.
쎲
Technical feature:The required PLC driver isintegrated in the Mitsubishi Alarm Modem.
The Mitsubishi Alarm Modem and the PLC can speak a joint language.
쎲
Technical feature: Mitsubishi Alarm Modem and PLC use the same protocol,
e.g. Modbus.
9.1PLC driver in the Mitsubishi Alarm Modem
Mitsubishi Alarm Modems can communicate with the relevant PLCs using their protocols with
out having to load a program, driver or function block into the PLC concerned. They then have
direct access to all variables, markers and I/O on the PLCs.
The Alarm Modem can easily be set with parameters using the software MX-Mitsubishi Alarm
Editor.
These PLCs are supported:
Alpha XL and MELSEC FX1S/1N, FX2N/2NC
For MAM-PLC communication, the internationally standardized fieldbus system Modbus
(ASCII and RTU) may also be utilized.
