ZDUE-GPRS-PLUS-VI
Attention
A precondition for use of the GPRS/IP server functionality of the ZDUE-
GPRS-PLUS-VI is that the GPRS mode is activated in class 82.
The GPRS mode is deactivated by default!
The ZDUE-GPRS-PLUS-VI can be operated as an IP server. In this GPRS
mode a client (e.g. a control centre) establishes a bidirectional data
connection via the GPRS (General Packet Radio Service) of a GSM network
(Global System for Mobile Communication).
The communication via TCP/IP protocol that is necessary for this is provided
by the ZDUE-GPRS-PLUS-VI. It transmits data from electricity meters as well
as meters for other media which can be connected to the ZDUE-GPRS-
PLUS-VI's interfaces and that are not TCP/IP capable themselves.
The ZDUE-GPRS-PLUS-VI in GPRS mode functions largely in the same way
as the CSD mode described above. Special features are described in the
following sections.

Meter data and configuration via TCP/IP
Attention
In order to establish in GPRS mode an IP connection to the ZDUE-GPRS-
PLUS-VI from a client, the IP address of the ZDUE-GPRS-PLUS-VI must be
known to the client. For this reason it is advisable to use a SIM card with an
assigned fixed IP address.
