Components
3.4 Wireless Remote Access
Wireless remote access is realized by an internal GRPS / GSM access
modem that is permanently connected to the Internet.
Depending on the modem the Energy Manager is delivered in the
following variants:
• Energy_Manager 2.0 with 3G Modem US
• Energy_Manager 2.0 with 3G Modem EU
• Energy_Manager 2.0 with 2G Modem
Energy_Manager 2.0 without Modem
The wireless remote access module is used for:
•
Connecting the Energy Manager to the Remote Management
Server. Life signals containing site data are sent at regular
intervals from the Energy Manager to a Remote Management
Server and stored there. See also Remote Management Server
(RMS) on page 21 and Live Access Application (LAA) on page 21.
•
Sending event triggered life signals in real time.
•
Sending events, such as diesel fill level, and changes in the status
of the components, as an SMS message from the Energy Manager
to an administrated telephone number.
Each customer and partner is given a separate login and password that
allows remote access to the Energy Manager on authorized sites and
systems.
During the transmission of an SMS, remote access is interrupted. After the
successful transmission of an SMS, a new connection to the server is
automatically established by the wireless access module.
Several types of SIM cards from different providers can be used for calling
a party address and charging the data transfer.

The SIM card is globally Internet-capable through its APN
TIP
Heliocentris recommends a flat-rate data plan or a volume-based rate plan
with a very high minimum volume. Prepaid cards should not be used.
