Range of application
The Alarm Modem IE-GPRS-I/O is designed to collect messages in
industrial plants and building installations. The messages are detected
as activated switching contacts and analog limit values. Via a serial
protocol, the higher-level plant or system may either receive data or
control the data traffic itself.
The communication with the server is performed over a virtual
dedicated line via GPRS as a point-to-point, multipoint or multi-drop
connection. An Internet exchange server may log the states of the
inputs and outputs permanently on the basis of event or time control.
The server constitutes a relational database, i.e. external access is
possible via SQL queries.
The exchange server is a service provided by Weidmüller.
The configurable alarms are issued via SMS, e-mail, voice messaging
and/or fax.
The IE-GPRS-I/O implements telecontrol by remote-switching of the
outputs via telephone/mobile telephone.
The IE-GPRS-I/O can be teleserviced and remote-configured.
DANGER
Any errors in configuration, in the execution of any work or
operations, as well as inadvertent false operation may impair the
proper functioning of the IE-GPRS-I/O, resulting in personal injury,

Description of Functions
3.2.6 GSM modem
The GPRS module realises a virtual dedicated line. With an M2M
GPRS tariff of a mobile telephone provider, the only costs in addition to
a low fixed monthly charge are the costs for the actual data transfer. No
permanently installed fixed-network telephone connection is required.
Each IE-GPRS-I/O can be accessed online at any time in the same way
as a mobile telephone.
The data transfer is not provided via the exchange of telephone
numbers, but via an Internet-based protocol. The data are collected on
an exchange server and can be requested there at any time, without the
need to establish a direct connection to the IE-GPRS-I/O. The router of
the mobile telephone provider need not be configured.
Thanks to the use of non-public IP addresses of the provider, the
IE-GPRS-I/O is invisible to the Internet.
Additionally, software is supplied for an exchange server, which, for
example, can also be operated after a router.
3.2.7 SIM card
A SIM card is used to set the selected tariff and the possible
communication services for the IE-GPRS-I/O. The availability of the
services fax, e-mail and voice depends on the chosen tariff and on the
enabling of the SIM card used, see SIM card agreement.
Before you insert the SIM card, first turn off the device!
CAUTION
Inserting the SIM card
Use a pointed object to press gently into the hole beneath the SIM card
compartment and open the SIM card compartment. Insert the SIM card
into the card compartment such that the contact faces are visible.
3.2.8 GSM services
For the case that the virtual GPRS line is interrupted, alarms can be
issued additionally via the GSM network using the configurable services
SMS, e-mail, fax and voice messaging.

Description of Functions
3.3
Settings of the operating system
3.3.1 (Firmware) update for the operating system
The operating system of the IE-GPRS-I/O is subject to continuous
further development to adapt it to the technical requirements and
customer wishes. Devices which are already in use may thus also
require a new operating system. The version of operating system
currently installed on your IE-GPRS-I/O can be displayed on the About
page of your web browser (see Section 4.16 About) or read out using a
terminal program (see Section 3.4.1).
When loading a new operating system, it may be necessary to reset all
settings to the factory defaults.
CAUTION
If the IE-GPRS-I/O is reset manually to its factory default settings
after installing the operating system, all settings already made are
lost; the user name and the password are also reset to the factory
defaults. Therefore, you should always document the current
settings before you make an update!
After the update, check both all settings and the access
protection.
To load the operating system, use a loader.

http://192.168.1.120/index.htm.
•
After a few seconds, the start page of the parameterisation user
interface is displayed.
The IE-GPRS-I/O is addressed directly via the long-distance data
transmission connection and cannot itself communicate with a network
connected to the PC. The IP address of the IE-GPRS-I/O is not visible
in the network of the PC. Thus, no attacks are possible against the
IE-GPRS-I/O from the network. Furthermore, no address conflicts result
with devices with the same network address in the network.

PC. To do so, you will need an analog modem.
The connection to the IE-GPRS-I/O is again established via "Dial-Up
Networking".
In "Properties" of "Dial-Up Networking", set the analog modem as the
transfer device.
Enter the number of your IE-GPRS-I/O as the dialling number; the
dialling number is indicated in your SIM-card agreement.
After establishing the connection, you can configure your IE-GPRS-I/O
as described in Section 4 Configuring the .
Reloading of the operating system is not possible via teleservice!
NOTE
NOTE
If no communication to the IE-GPRS-I/O can be established within
5 min., the connection is cancelled. The connection is also
cancelled, if no data have been transferred for 5 min. when the
connection is active. Subsequently, the IE-GPRS-I/O must be
reselected. Thus, unnecessary connection costs are avoided, as
would otherwise result if the connection was not cancelled
manually.

Description of Functions
3.4.3 The "Passive" mode
The "Passive" mode provides a data connection from a remote PC, via
a modem and the IE-GPRS-I/O to a device connected to the serial
interface of your IE-GPRS-I/O.
Procedure
•
The PC calls the IE-GPRS-I/O via a modem.
•
The IE-GPRS-I/O accepts the call and establishes a connection.
•
On the basis of the first data sent by the PC, the IE-GPRS-I/O
decides whether the data are part of a remote configuration for the
IE-GPRS-I/O or whether the data are intended for a downstream
device.
•
If the data are intended for a downstream device, they are passed
to the serial interface. All data sent by the downstream device to
the serial interface are sent without changes to the remote
computer via the modem connection.
3.4.4 The "Transparent" mode
In the "Transparent" mode, it is possible for the internal GSM/GPRS
modem to be controlled by a downstream device.
•
In this case, the establishing, cancellation and monitoring of the
connection must be controlled by the downstream device.

Measured value
•
This field displays the measured value of the inputs.
•
Clicking on the field refreshes the measured values of the two
analog inputs.
Factor
•
It is possible to scale the measured value with a factor.
In this case, the calculation is performed as follows: (Factor ∗
measured value) + offset, i.e. the slope of the measurement
characteristic is not changed so that the displayed measured value
can be matched to the physical measurement quantity.
Example: Assumed 0 … 10 V is to correspond to a water level of
0 … 100 cm, the factor to be set is 10.
Offset
•
It is possible to shift the measured value using an offset.
In this case, the calculation is performed as follows: (Factor ∗
measured value) + offset, i.e. the zero of the measurement
characteristic is offset.
Debouncing time
•
The measured value must have been either higher or lower than
the appropriate limit value for at least the set debouncing time for a
message to be triggered.
Display unit
•
A unit, e.g. "V", which is inserted into the text block #AI1#, #AI2#,
together with the measured value.
•
Max. 3 characters.
Upper limit value
•
If the measured value exceeds the upper limit value, a message
can be triggered.
•
Further messages can only be triggered if the measured value has
fallen below the lower limit value and has then again risen above
the upper limit value.
Text for upper limit value

Report
•
If this field is checked, a message is triggered when the upper limit
value is exceeded.
Lower limit value
•
If the measured value is lower than the lower limit value, a
message can be triggered.
•
Further messages can only be triggered if the measured value has
risen above the upper limit value and has then again fallen below
the lower limit value.
Text for lower limit value
•
A text that can be inserted into the message text using the text
block #VAL#; thus, it is possible to modify the message text
dynamically, depending on the particular event;
•
Max. 16 characters.
Report
•
If this field is checked, a message is triggered when the measured
value falls below the lower limit value.
Signalling when the measured value is lower/greater than a limit
value
•
If the measured value falls below the lower limit value or exceeds
the upper limit value, a message is triggered.
•
Further messages can only be triggered after the measured value
has fallen below or exceeded the corresponding other limit value.
Change
Signals when a measured value changes.
•
A message can be triggered if a measured value changes by a
certain amount.
•
The appropriate change is specified as a percentage and refers to
the measuring range of the input, e.g. voltage 0 ... 10 V; 10 %
corresponds to a change of 1 V.
If a measured value is monitored for changes, the debouncing time
is not considered, meaning that a message is triggered
immediately if the measured value changes accordingly.

this makes sense, for example, with graduated standby services.
Enter the appropriate target mobile telephone number for short
messages (SMS).
Enter the appropriate target e-mail address for e-mails, etc.
Service
•
Select the appropriate transmission method,
e.g. D1 SMS = Send SMS via the D1 network / E-mail = Send email to the specified address, etc. ...
The messaging service must correspond to the target! For
example, you cannot sent an SMS to an e-mail address.

Configuration
▫ The message targets form a message sequence.
The message sequence is interrupted if a target of this sequence
was informed successfully, including acknowledgement.
▫ If a message target is to be informed in any case, irrespective of
its position in the message sequence, the message targets must
be marked additionally with "ALW".
- Example: Shift schedule in a sequence of 3 and additionally a
fax to the exchange centre, which is always to be sent. ▫ Message targets that are marked with an "I" have no influence on
the message sequence, i.e. even if such a message target was
informed successfully, the message sequence is not quit.
Weekday
•
The relevant message is only sent on the marked days of the week;
thus, a simple shift schedule can be realised.
from - to
•
The message is sent during the time "from - to".
•
If the time period passes midnight, the message is still sent even if
the second day of the week is not marked,
for example, from = 07:00 p.m. to = 08:00 a.m. Mon
Tue is marked.
If the input is now triggered on Wednesday at 07:50 a.m., the
message is sent even though Wed is not marked.

Authentication
• Most e-mail providers require an authentication to send e-mails via
an SMTP server.
•
Selection:
▫ none
No authentication is required, or the authentication is provided
via the senders and often via the recipient's e-mail address (see
Section 4.6 Alarm Message).
In other words: Only e-mails with certain addresses can be sent.
▫ SMTP after POP
An authentication procedure which is supported by many e-mail
providers.
Before sending an e-mail, the user must access his e-mail inbox
(see below) using his password and his user name.
Subsequently, he is left a defined time window of, for example,
15 minutes, within which he may send e-mails via SMTP. Thus,
the successful POP authentication serves as an authentication

DNS1
•
Optional DNS (Domain Name Server)
Syntax: e.g. 217.237.151.97
•
Normally, no entry is necessary, since the settings are transferred
by the ISP.
•
Even if a DNS is received by the ISP, it is not this entry which is
used, but that of the ISP.
DNS2
•
Optional DNS (Domain Name Server)
Notification: e.g. 217.237.151.97
•
Normally, no entry is necessary, since the settings are transferred
by the ISP.
•
Even if a DNS is received by the ISP, it is not this entry which is
used, but that of the ISP.

Two ISPs can be configured, e.g. one for GPRS and one for GSM.
Thus, if GRPS is not available, it is nevertheless possible to send
an e-mail as an error message.
ISP2
ISP2 is the backup connection for ISP1. Status messages via e-mail are
sent via IPS1 and GPRS by default. In case of failure of this connection,
an error message, e.g. via e-mail, is sent via the connection configured
under ISP2. Thus, alternative sending is possible via GSM.

4.10 Server
The Internet exchange server is operated with further partners on behalf
of Weidmüller. The server is a relational database which can be
accessed externally via SQL queries. The server itself need not be
configured externally by the customer. To be able to use the server,
only the following settings are required:
Interconnection between two or several IE-GPRS-I/Os to one another
can only be provided via the exchange server. The exchange server
performs the data transfer from one IE-GPRS-I/O to the other
IE-GPRS-I/O or within a group of several IE-GPRS-I/Os.
All IE-GPRS-I/Os log into the exchange server with a password, a code
and a group. Several IE-GPRS-I/Os of a group can communicate with
each other; the IE-GPRS-I/Os of different groups, however, cannot
communicate with each other.
IE-GPRS-I/Os may be master, slave or master/slave.
A master sends data to all slaves and master/slaves of a group, not to
other masters. The master receives data from all slaves and
master/slaves of a group, but not from other masters.
A slave sends data to all masters and master/slaves of a group, not to
other slaves. The master receives data from all masters and
master/slaves of a group, but not from other slaves.

The IE-GPRS-I/O monitors the data volume for GPRS connections and
the online time for GSM connections.
To this end, you must enter the specifications from your mobile
subscriber agreement in the menu Cost control.
Rounding error
•
Each time a connection is established to the GPRS network, the
provider debits a certain data volume from you at a flat rate. The
amount of this value depends on the appropriate mobile subscriber
agreement. It is recommended to use ALWAYS a tariff model with a
rounding error as low as possible.

Byte counter
The following limit values can be set for two graduated report
messages.
Example:
•
▫ If a volume tariff of 10 MB/month was agreed with the mobile
service provider, with byte counter1 = 5 MB, a report message is
issued when half of this volume has been used, and with byte
counter2 = 8 MB again at 80 %. The setting is made in the menu
"Messages", see Section 4.6 Alarm Message.
Online time
Due to technical reasons, the counter can only provide a rough
overview (guide value) of the actually used volume.
Example:
▫ Necessary repetitions when sending data which cannot be
protocolled by the IE-GPRS-I/O
▫ Different protocol overheads when sending

Glossary
This chapter provides a list of all abbreviations and special terms used
in this Manual with their meanings.
A
•
AT commands
The term 'AT commands' is used for the commands that were
originally used by the company Hayes and thus have become
quasi-standard for configuring and parameterising modems.
•
DNS
The Domain Name System (DNS) is one of the most important
services on the Internet. The DNS is a distributed database that
manages the name space on the Internet. Generally, the DNS is
used to convert names to addresses (forward lookup). This is
comparable with a telephone book that resolves the names of the
subscribers into their telephone numbers. For example, you can

DHCP
Dynamic Host Configuration Protocol. An IEFT (Internet
Engineering Task Force) protocol. The Dynamic Host Configuration
Protocol is the function used by the DHCP client to fetch a TCP/IP
address from a central computer (DHCP server). The DHCP server
assigns the client this IP address from a defined address range
dynamically. In other words: The client is always assigned a new,
but unambiguous IP address so that DHCP can supply, for
example, mobile PCs, with IP addresses.

Download
Download is a technical term from the field of IT. During a
download, the data are requested from a remote station (e.g.
network computer, Internet) and transferred to the computer. The
download is thus the opposite to the upload.

Dynamic IP
IP address, is assigned to the client from a defined address range
dynamically, e.g. via a DHCP server.
•
Fixed IP
Fixed IP addresses are assigned statically to the client by the
appropriate Internet provider.
•
GSM
The Global System for Mobile Communications (GSM) is a fully
digital mobile communication network standard that is used mainly
for telephony, but also for line-switched and packet-switched data
transfer and for short messages (SMS).
•
GPRS
GRPS is an extension of the GSM mobile telecommunication
standard - a packet-oriented data transfer which - at least for
advertising purposes - is often also called 2.5G (two point fifth
generation). This naming is effectively a reference to UMTS (3G).
Unlike than the line-switched data service HSCSD, GPRS is
packet-oriented. In other words: While still at the sender, the data
are converted into individual packets, transferred as such and
recompiled with the recipient.
•
IPCP
IP Control Protocol. A network control protocol that - among other
services - serves for negotiating of a compression algorithm and for
transfer of a dynamic IP address (RFC1332).

IP
The Internet Protocol (IP) (also called Internet protocol) is a
network protocol widely used in computer networks. It is an (or
indeed the) implementation of the Internet layer of the CP/IP model.

Private IP
Private IP addresses or private networks are IP addresses/subnets
that can be used for any purpose and by everybody. However, they
are not routed on the Internet.

PPP
Point to Point Protocol. Universal point-to-point protocol that
includes various forms of connection, a dynamic understanding on
options, authentication functions and also functions for establishing
and cancelling connections and their monitoring.

SMS
Short Message Service (SMS) is a telecommunication service for
the transferring of text messages which was originally developed
for GSM mobile communication and is now also available in the
wireline network. Further developments of SMS exist under the
names Enhanced Message Service (EMS) and Multimedia
Messaging Service (MMS).

TCP
The Transmission Control Protocol (TCP) is a reliable, connectionoriented transfer protocol in computer networks. It is part of the
TCP/IP protocol family. TCP provides a virtual channel between
two computers (more exactly: the end points (sockets) of two
applications on these computers). Data can be transferred on this
channel in both directions. In the most cases, TCP is based on the
IP protocol.
•
UDP
The User Datagram Protocol (UDP) is a minimum network protocol
without connection. It is part of the transport layer of the TCP/IP
protocol family and is - in contrast to TCP - not designed for
reliability. UDP has the main objective to extend the connection to
the end system established by the IP layer by a user interface
(ports). The quality of the underlying services, in particular, the
reliability of the transfer, however, is not increased by the UDP.
•
Upload
Upload is a technical term from the field of IT. During an upload,
data are transferred from a computer to a remote station (e.g.
network computer, Internet). The upload is thus the opposite to the
download.
•
VPN
A Virtual Private Network (VPN) is a computer network that uses a
public network (for example, the Internet) to transfer private data.
Subscribers to a VPN can exchange data in the same way as in an
internal LAN. The connection of the networks is provided by a
tunnel between VPN client and VPN server. In the most cases, the
tunnel is secured, but an unsecured clear-text tunnel is also a VPN.
IP VPNs use the Internet for transferring IP packets independently
of the transmission network, which - in contrast to direct remote
access to an internal network (direct dialling, for example, via ISDN,
GSM...) - provides significantly more flexibility and is more costeffective.
