2.1Range 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.

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,

DANGER 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 Equipment of Machines).

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.

Description of Functions

3.3Settings 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.

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

CAUTION 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
	ie-gprs-io-xxxxx.hex	Loader file
	xxxxx stands for the version number

It is not necessary that both files are in the same directory.

•Connect the RS232 of your IE-GPRS-I/O to COM1 or COM2 of your PC.

•Turn off the IE-GPRS-I/O.

3.4Communication between PC and IE-GPRS-I/O

The communication is realised via a serial connection. To display the HTML user interface of the IE-GPRS-I/O, Microsoft Internet Explorer, version 5.5 or higher is required. For the relevant

NOTE information required to configure the IE-GPRS-I/O via the serial interface, please refer to Section 4.1.

To configure the IE-GPRS-I/O using the HTML user interface, it is imperative to know the current Ethernet address of your IE-GPRS-I/O. The factory setting is 192.168.1.120.

•In the Windows operating system, set up the IE-GPRS-I/O as a long-distance data transmission connection ("Dial-Up Networking", see Section 4.1.1 Setting up the virtual modem and the longdistance data transmission connection under Windows XP).

•Configure a serial COM interface of your PC for the IE-GPRS-I/O

(see Section 4.1 Configuring the 218HIE-GPRS-I/O via the RS 232 interface).

•Establish the connection either by clicking on the previously created shortcut on the desktop or use Start – Settings - Dial-Up Networking - IE-GPRS-I/O ;

IE-GPRS-I/O stands for the name of the connection.

•In the Internet explorer, call the start page 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.

3.4.2 Remote servicing

NOTE

NOTE

It is possible to make all settings for the IE-GPRS-I/O from a remote 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!

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.

3-24

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.
