Attention
To use the GPRS-/IP-Telemetry funktion of ZDUE-GPRS-PLUS-VI it is
required, that the GPRS mode in parameter class 70 is activated. This
setting takes priority over the GPRS-/IP server mode (parameter class 82)
By default the GPRS-IP-Telemetry mode is NOT activated.
In GPRS-IP-Telemetry mode, as soon as a connection to internet or intranet
via GPRS is available, the ZDUE-GPRS-PLUS-VI establishes an IP
telemetry connection in accordance to E DIN 43863-4 to a selected IP-T
master. Therefore a corresponding account must be configured at the IP-T
master (e.g. Dr. Neuhaus TAINY SwitchingCenter V3). The login is made by
using login name and password.

The control station is also connected to the IP-Telemetry master. All the
communication between control station and ZDUE-GPRS-PLUS-VI is
transferred via the IP-Telemetry master.
The ZDUE-GPRS-PLUS-VI provides the opportunity to define a secondary
IP-Telemetry master. If the connection to an IP-Telemetry master cannot be
established (e.g. master not reachable) or is refused by the master (e.g.
invalid user name/password combination), the other master can be used as
an alternative by the ZDUE-GPRS-PLUS-VI.
The primary and secondary IP-Telemetry master may also reject a login
attempt for load balancing reasons, provided this service is activated within
the respective TAINY SwitchingCenter. In this case the rejecting IP-
Telemetry master reroutes the ZDUE-GPRS-PLUS-VI by sending the IP
address of an alternative IP-Telemetry master to the device. This IP address
is independent from the server settings of the ZDUE-GPRS-PLUS-VI.
In the GPRS-IP-Telemetry mode, the function indicators behave the same
as in the CSD mode; An existing IP-Telemetry connection is not indicated.
