2 TECHNICAL DESCRIPTION
The ACCON-MPI-Modem GSM enables the remote maintenance of a S7
controller via the GSM network. The connection is done via GSM or
locally via RS232. The ACCON-MPI-Modem GSM is a compact device. It
contains an ACCON-MPI/TS-Adapter and a GSM modem. The ACCON-
MPI-Modem GSM uses the same communication protocol as the TS
Adapter. Thus the device can be used with all software which supports
this adapter. There is also an additional bushing to connect a further
station e. g. a control panel, to the bus plug of the ACCON-MPI-Modem
GSM. To use the ACCON-MPI-Modem GSM with STEP 7 via a modem
connection, you need the TeleService option package from Siemens.

LED display
The six LEDs on the front side of the device inform about the operating
state of the ACCON-MPI-Modem GSM. So sources of error can be
detected very quickly.
When the ACCON-MPI-Modem GSM is connected to the PLC a
connection with the MPI bus will be established if the initialization of the
internal modem was successful. Then the Active LED lights. If not the
initialization of the modem or the log in on the MPI bus does not work.
The device can only accept incoming connections when the Active LED
lights.
The LEDs can change to one of three possible states: ON, OFF,

5 REQUIREMENTS FOR OPERATING
Hardware requirements
If possible put the ACCON-MPI-Modem GSM directly on the MPI
interface of the SIMATIC S7-300 or S7-400 controller. You always have
to use the 24 VDC external power supply for the ACCON-MPI-Modem
GSM.
Please keep in mind that the ACCON-MPI-Modem GSM cannot be used
with PROFIBUS!
When using the device abroad, it is recommended to get information
about the local radio networks and its frequencies. Contact the network
operators in the respective country. Please remember to use a suitable
antenna for the used frequency band.
Software requirements
To use the ACCON-MPI-Modem GSM as programming adapter you need
SIMATIC STEP 7 from version 5.1. And for an access via a modem
connection you need the TeleService options package from Siemens.
ACCON-MPI-Modem GSM 10

Minimum clearance
The following minimum clearance has to be kept that
• you can assemble and disassemble the ACCON-MPI-Modem GSM
without disassembling other parts of the facility.
• there is sufficient space to connect all interfaces and connections
to standard accessories.
• there is enough room for cable routings.
Figure 2: Minimum clearance
Module assembly
A top hat rail holder is supplied.

6 COMMISSIONING
Connecting the antenna
On the front side of the ACCON-MPI-Modem GSM there is an antenna
connection (FME plug). The antenna (FME bushing) is screwed in there
and installed at a place with the best radio network quality.
Example: Assembly of the magnetic base antenna
Figure 3: Connecting the antenna
Inserting the SIM card
To access a GSM network you need a SIM card from a provider. Please
see that the SIM card has a special call number for incoming data calls
(CSD connections). Without this data call number you cannot use the
SIM card with the ACCON-MPI-Modem GSM.
Before inserting or changing the SIM card you have to interrupt the
device’s supply voltage!
ACCON-MPI-Modem GSM 12

Figure 1: Release button and SIM card holder
The holder for the SIM card is located sideways. By pushing the
countersunk yellow button (e.g. with a biro) the card slot will be ejected
that the SIM card can be inserted or removed.
The SIM card must be inserted with the contacts upside into the card
holder. After that push the card holder with contacts on the left into the
card reader until it snaps in.
Figure 4: Inserted SIM card and ready-to-operate system
You can use 1,8 V as well as 3 V SIM cards.
Only insert and change the SIM card when the device is off!
ACCON-MPI-Modem GSM 13

Data transfer
For the SIM card the GSM provider has to activate a separate call
number (incoming data calls CSD). A SIM card can be unlocked for
incoming voice and data services at the same time. Then the SIM card
has its own call number for each connection type. Normally, the
following contracts are possible:
Function Prepaid
card
Contract for
voice
transmission
Contract for
data

Data
connection
outgoing
999
Data

incoming
- - 9
SMS 999
Voice

99-
Table 1: Services for the SIM card
Different call numbers for incoming calls are assigned to the different
services. The GSM network does not redirect e.g. a data call to the call
number for voice connections. Please attend to dial the correct call
number.
You can establish a data connection between the following:
analog ISDN GSM
analog Yes No Yes
ISDN No Yes No
GSM Yes No Yes
Table 2: Connection types
ACCON-MPI-Modem GSM 14

Connecting to the automation system
Connect the 9-pin SUB-D plug to the MPI interface of your S7 controller.
When the ACCON-MPI-Modem GSM is connected to the PLC at the plant
a connection to the MPI bus will be established if the initialization of the
internal modem was successful.
If the Power LED does not light, either the modem did not answer to the
initialization with »OK« or the ACCON-MPI-Modem GSM was not able to
log in on the MPI bus (perhaps wrong MPI address). At this time remote
maintenance is not possible.
Connection to the PC
The ACCON-MPI-Modem GSM will be connected to the PC's RS232
interface via the supplied null modem cable. So the ACCON-MPI-Modem
GSM can be parametrized or used for the communication as a PC
Adapter. You can change between the different modes via the
microswitch.
Internal: Modem operating in a telephone network (microswitch
position: »Int.«)
When the micro switch is in the »Int.« position, the ACCON-MPI-Modem
GSM works directly with the integrated modem. The RS232 LED is off
and the RS232 interface has no function. The access on the connected
PLC via TeleService is active.
External: RS232 direct operating at a PG/PC (microswitch position:
»Ext.«)
When the micro switch is in the »Ext.« position, the ACCON-MPI-modem
GSM works with a locally connected PC Adapter or TS Adapter. The
RS232 LED is green.
Modem: Modem operating (microswitch position: »Modem.«)
When the microswitch is in the »Mdm.« position, the ACCON-MPI-
Modem GSM works as an external GSM modem. The RS2323 LED is red.

Installation of the local modem
If you have already installed a modem under Windows, you can mostly
use it for the remote maintenance. In this case you can skip this step
and use the already installed modem. Plug&Play modems will be
detected automatically after they have been connected to the PC. But
you need the driver supplied with the modem. None Plug&Play modems
can be installed manually via Control Panel > Phone and Modem
Options > Modems. The supplied driver is needed here, too.
Alternatively, you can use one of the standard drivers supplied with
Windows (e.g. Standard 28800 bps Modem). You can choose the
installed Modem in the programming software's settings. You choose
the installed modem in the programming software during connection
establishment.

Figure 6: Setting the local modem
For analog connections to the GSM network you have to set the
transmission service V.32.
ACCON-MPI-Modem GSM 17

7 INSTALLATION OF THE ACCON-MPI-MODEM GSM
AT THE PLANT
Assemble the ACCON-MPI-Modem GSM in the control cabinet
remembering the minimum clearance.
Energize 24 VDC to the power supply bushing and assemble the
antenna. Please keep the polarity in mind. If the device is fed with
voltage only the Power and RS232 LED should light green. If the RS232
LED is of or lights red then change the microswitch to »Ext.«.
Connect the ACCON-MPI-Modem GSM to the RS232 interface of your
PC or PG via the supplied null modem cable.
Parametrization with TeleService
The settings of the ACCON-MPI-Modem GSM are defined by the
software with which the communication to the automation device is
done.
In addition to the programming software STEP 7 you need TeleService
from Siemens (from version 3.0) to administrate the connections (phone
book) and establish a dual-up connection to the controller.
Adjust the connection in the dialog Set PG/PC Interface as follows:
Figure 7: Set PG/PC Interface
Choose the PC's COM port to which the ACCON-MPI-Modem GSM is
connected to.
ACCON-MPI-Modem GSM 18

Via the menu Options > Assign TS Adapter I/II parameters in the
TeleService software, you can define the following settings for the
internal adapter and the internal analog modem.
Transmission rate from internal adapter to the modem:
Figure 8: Serial parameters
Modem settings / Initialization string
To log in on the GSM network the personal identification number (PIN) is
needed. It is stored in the initialization string (Init string) of the ACCON-
MPI-Modem GSM. The Init string is set with the TeleService software or
ACCONfigurator.
Setting the PIN with TeleService
Go to the tab »Modem«.
You have to add »AT+CPIN="PIN"« in the Init string.
ACCON-MPI-Modem GSM 19

Figure 9: Setting initialization string
The PIN 9135 is just an example. Please enter
your
4-digit PIN!
The complete initialization string could look like the following:
AT+CPIN="9135";AT&FE1L1M1Q0V1&C1S0=1
It consists of two command sequences which are separated by a
semicolon. The first one is only sent when activating the ACCON-MPI-
Modem GSM, the second after a connection loss. Only change the
settings when you are sure that the AT control sequence is correct!
The second part contains the basic settings which normally need not to
be changed.
