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 Equipment of Machines).

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.
