2 TECHNICAL DESCRIPTION
The ACCON-MPI-Modem ISDN enables the remote maintenance of a PC
via the MPI interface of a S7 controller. The connection is done via a
telephone connection. The ACCON-MPI-Modem ISDN is an ACCON-
MPI/TS-Adapter with an integrated modem. Due to the integrated
modem, the remote maintenance adapter is a compact device which can
be placed in every control cabinet. The ACCON-MPI-Modem ISDN 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 socket to connect a further station e. g. a control panel, to
the bus plug of the ACCON-MPI-Modem ISDN. To use the ACCON-MPI-
Modem ISDN 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 ISDN. So sources of error can be
detected very quickly.
When the ACCON-MPI-Modem ISDN 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,
BLINKING

5 REQUIREMENTS FOR OPERATING
Hardware requirements
If possible, put the ACCON-MPI-Modem ISDN directly on the MPI
interface of the SIMATIC S7-300 or S7-400 controller. If not possible
you have to use an external power supply for the ACCON-MPI-Modem
ISDN.
Please keep in mind that the ACCON-MPI-Modem ISDN cannot be used
with PROFIBUS!
Software requirements
To use the ACCON-MPI-Modem ISDN 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 ISDN 10

Minimum clearance
The following minimum clearance has to be kept that
• you can assemble and disassemble the ACCON-MPI-Modem ISDN
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
Connection to the automation system
Connect the 9-pin SUB-D plug to the MPI interface of your S7 controller.
When the ACCON-MPI-Modem ISDN is connected to the PLC, the
connection to the MPI bus will be established when the initialization of
the internal modem has been successful. The Active LED should light
after a short period.
If the Power LED does not light, either the modem did not answer to the
initialization with »OK« or the ACCON-MPI-Modem ISDN 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 ISDN will be connected to the PC's RS232
interface via the supplied null modem cable. So the ACCON-MPI-Modem
ISDN 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
ISDN 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
ISDN works with a locally connected PC Adapter or TS Adapter. The
RS232 LED is green.
Modem: Modem operating (microswitch position: »Mdm.«)
When the microswitch is in the »Mdm.« position, the ACCON-MPI-
Modem ISDN works as an external analog modem. The RS232 LED is
red.
ACCON-MPI-Modem ISDN 12

Figure 3: Build-up
Local modem
If you have already installed an ISDN modem or ISDN card under
Windows, you can mostly use it for the remote maintenance. Please you
use the data transmission protocol X.75.
Example: Setting the local modem
Figure 1: Phone and Modem Options
ACCON-MPI-Modem ISDN 13

For call-back function of the TS adapter you have to define at the local
modem a MSN(multiple subscribe number)for the data port. For this
special AT command please look for your modem documentation.
Installation of the ACCON-MPI-Modem ISDN at the plan
Assemble the ACCON-MPI-Modem ISDN in the switch cabinet
remembering the minimum clearance.
If necessary energize 24 VDC to the power supply socket. Please keep
the polarity in mind. Connect the ACCON-MPI-Modem ISDN to the
telephone network via the ISDN connection cable. 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 ISDN 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 ISDN 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.
Parametrization with TeleService
Adjust the connection in the dialog Set PG/PC Interface as follows:
Figure 4: Set PG/PC Interface
ACCON-MPI-Modem ISDN 14

Choose the PC's COM port to which the ACCON-MPI-Modem ISDN is
connected to.
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 5: Serial parameters
Modem settings / initialization string
Setting the MSN with TeleService
When operating the ACCON-MPI-Modem ISDN with an ISDN connection
for multiple devices with several terminal equipments, you have to
assign the MSN (multiple subscribe number) to the internal modem
module.
ACCON-MPI-Modem ISDN 15

For that purpose you have to send the command »AT#Z=xxx« (replace
xxx by the desired MSN) to the internal modem. The modem stores the
MSN permanently but can be overwritten by a new MSN.
Figure 6: Set initialization string
The complete initialization string could look like the following:
AT&FE1L1M1Q0V1&C1S0=1;AT#Z=112
AT Initiate modem commands
&F Load modem factory defaults
E1 Echo of commands ON
L1 Sound volume level 1
M1 Speaker ON
Q0 Modem response ON
V1 Response in plain text
ACCON-MPI-Modem ISDN 16

&C1 DCD signal shows available carrier
S0=1 Automatic call acceptance. The number 1 stands
for rings until call acceptance e.g. S0=3 the
modem accepts the call after 3 rings.
#Z=112 Adjust MSN
Password protection and call-back
Go to the tab »Access Protection«.
Figure 7: Access Protection
There you can create three different users including call-back number
and password. The user »ADMIN« is the only one who has the right to
change all settings in the adapter including the settings of the other
users. The other two users can only change their own password and call-
back number. If a call-back number is set, the ACCON-MPI-Modem ISDN
always uses this number to call back if the respective user logs in.
ACCON-MPI-Modem ISDN 17

If you enter a wrong call-back number for the user »ADMIN« the ACCON-
MPI-Modem ISDN cannot be parametrized via a remote connection any
more. In this case you can only change the call-back number directly at
the device (microswitch position »Ext.«)!
Save the settings with »OK« in the adapter and answer the eventually
appearing warning:
Figure 8: Parametrizing adapter, set access protection
»The administrator is neither protected by a password nor by a
call-back number. Do you want to set a protection function?«
By clicking on »No« all settings will be stored in the adapter despite the
warning. By clicking on »Yes« you get back to the settings.
Now the ACCON-MPI-Modem ISDN is parametrized. Change the
microswitch to »Int.« and wait until the Active LED lights. If not the
settings of the ACCON-MPI-Modem ISDN are incorrect (normally, wrong
bus settings or init string) and remote maintenance is not possible.
The parametrization can be done locally via the TeleService software
( microswitch position »Ext.« ) as well as via a telephone connection
(
microswitch position »Int.« ).
The ACCON-MPI-Modem ISDN is ready to operate when the Power LED as
well as the Active LED is on.
ACCON-MPI-Modem ISDN 18

7 PARAMETRIZATION WITH ACCONFIGURATOR
Using ACCONfigurator it is possible to parametrize or update the
ACCON-MPI-Modem ISDN at any PC without additional software e.g.
TeleService. The program can be found on the DELTALOGIC
Automatisierungstechnik-CD and on www.deltalogic.de.
