Since complying with Prime PLC specification, electricity meter G1B with PLC modem can
communicate to any Data Concentrator, supporting Prime PLC. Manufacturer recommends Data
Concentrator DMDC, produced by Elgama Sistemos Ltd.
Prime PLC modems support Plug&Play functionality. It enables automatic registering on network,
therefore additional configuration of communication devices is not needed during the installation
process. Furthermore, meter can send alarm messages in case of special events (e.g. tampering).
For more information about Plug&Play functionality see section 6.7.
6.4.1 Internal PLC modem
GAMA 100 meters may be equipped with internal PLC modem, installed under the main cover of
meter. This feature is available in modification, marked by code “H2” or “H3” (see section 4.9).
Internal PLC modem support functionality, described in section 6.4. Maximum self-consumption of
PLC modem is presented in
Table 6-1
. Internal PLC modem can be disabled (switched-off) by
special configuration command. This is usually carried out, when meter is connected to AMI
system by means of another modem (e.g. GSM/GPRS modem).

Status of internal PLC modem can be monitored on the LCD display of meter. Object “PLC status”
(OBIS = C.62.5) should be included in the display sequence, during parameterization of meter.
PLC status can be in one of the following states:
•
“PLC ---“ – meter is not connected to PLC network (see
Figure 6-4
);
•
“PLC On” – meter is connected to PLC network (see
Figure 6-5
);
•
“PLC Off” – internal PLC modem is switched off (see
Figure 6-6
).

6.5 Wired M-Bus module
GAMA 100 meters may be equipped with wired M-Bus Master interface for automated remote data
reading from gas and water meters. M-Bus interface is implemented according to EN-137757-2
and EN13757-3 standards. Hourly consumption data of water and gas meters is stored in M-Bus
load profile (see chapter 8.4).
