2.1 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.

DANGER

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.

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,
or material or environmental damage. Therefore, only sufficiently
qualified personnel are allowed to operate the IE-GPRS-I/O.

Always observe the safety notes!

The IE-GPRS-I/O is intended exclusively for use in machines complying
with the scope of application of DIN EN 60204-1:1998-11 (Electrical

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.

CAUTION

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!

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.

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.

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.

Files required: gprs-flash.exe Loader

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.

To start up your IE-GPRS-I/O, it must be configured first. The individual
steps for starting up will be explained in the present chapter.

4.1 Configuring the IE-GPRS-I/O via the RS 232

interface

The IE-GPRS-I/O is connected to a PC via the RS 232 interface
"RS232" using a modem cable. The RS232 protocol is used directly.
The IE-GPRS-I/O is addressed using Internet Explorer 5.5 or higher.

In the MS Windows operating system, install your IE-GPRS-I/O as a
modem for a long-distance data transmission connection.

4.1.1 Setting up the virtual modem and the long-

distance data transmission connection under
Windows XP/2000

already set up, proceed as described in Section 4.1.2.

• Installing a new modem:

Select Start – Settings – Control Panel - Phone and
Modem Options and there

is probably currently occupied by another interface driver, e.g. a
CAPI driver.
