3.5 Automatic call-back and SMS mes-
sages (G100 Radio/Modem/PLC only)
A G100 with a modem connection can be configured
for automatic call-back to one or more phone num-
bers (central management system) when one of the
connected GENIbus units goes into alarm condition,
e.g. blocked pump. The advantage of this function is
that regular dial-ups, or a fixed online connection, to
the system to be monitored are unnecessary.
The G100 can also be configured to send SMS mes-
sages via a GSM data modem (or via a UCP server
when a fixed-line modem is used) in case of an
alarm condition or other selectable events.
SMS messages can be combined with automatic
call-back so that both functions are carried out or
one is carried out only if the other fails. It is possible
to call back to five different phone numbers and the
call-backs can be controlled by other events than
faults:
• A GENIbus unit goes into alarm condition.
• A GENIbus unit comes out of alarm condition.
• A GENIbus unit goes into warning condition.
• A GENIbus unit comes out of warning condition.
• The G100 loses connection with a GENIbus unit
or gets into contact with a new GENIbus unit.
• Change of digital input.
These events can be selected or deselected as
desired. In addition, the "heartbeat" SMS function
can be set to send a message at fixed intervals, indi-
cating that the telephone modem connection is oper-
ational.

3.6 Other functions

The G100 is capable of monitoring the communica-
tion via the service port as well as the communica-
tion port to the main network. If the communication is
disconnected within a given configurable period, the
G100 will stop all connected GENIbus units using
bus commands. This function can be enabled or dis-
abled for each of the two communication ports.
In a given application, this function can be used to
stop all pumps in case of failing communication with
the central management system.
The G100 has an access code option for modem
communication. If the access code is not written cor-
rectly, the transmission of data to the G100 and the
GENIbus units will not be allowed. In this way, unau-
thorized persons are prevented from causing dam-
age to the system.
The G100 will log the last 10 alarms with address,
time stamp and cause. The alarm log can be useful
in connection with fault finding. The log can be
deleted by giving a command to the G100.

4. Profibus-DP

Description
The Profibus-DP builds upon a master-slave-princi-
ple, where the bus master (PC or PLC) also func-
tions as the link to an overlying management system
(SCADA system).
The G100 functions as a slave on the Profibus-DP
network.
G100 Profibus-DP address
When installing the G100, the G100 Profibus-DP
address must be set manually by the use of DIP
switches on the Profibus-DP expansion board.
See section 4.1 Profibus-DP settings.

4.1 Profibus-DP settings

The physical Profibus-DP address must be set on
the Profibus-DP expansion board, fig. 2. This should
be done before connecting the G100 to the Profibus-
DP.
Address

The G100 must be assigned a Profibus-DP address
which is not already being used on the Profibus-DP
network.
Example: The Profibus-DP address is set to No. 3
on the DIP switches in fig. 3.
