- With a Range of User Configured Settings, the New Plogg With ZigBee
PRO Provides for Faster Network Speeds and Larger Wireless Sensor Networks

Energy Optimizers Limited (EOL) has upgraded the wireless protocol for
their plogg wireless electricity meters to ZigBee PRO. The upgrade means that
interoperability with other manufacturers' wireless sensors is now more
easily achieved, thereby extending the possibilities for systems integration,
as well as reducing network response times.

Plogg is designed for use in Smart Grid, load analysis and appliance
testing trials, where accuracy and data resolution are paramount. The Plogg
Manager PC ( interface
allows the operator to install the plogg with up to thirteen different
logging parameters for time and electrical performance, to monitor maximum
values for consumption, current and voltage, and to set the logging interval
from 1 minute to 1 month. Plogg devices operate with single phase, split
2-phase and balanced 3-phase loads, with the option of an external CT version
for either whole house or large load measurement of up to 100A. A mesh
network of plogg devices can meter and control appliance loads through
wireless communications either with a local PC coordinator or remotely,
through an Ethernet access point or Plogg Network gateway.

Plogg instruments offer accuracy and configurability, with
self-calibration and interval logging set by the user in customised terminal
based software, all part of the Plogg Manager package. A download event
scheduler is pre-set at 15 minutes and transfers data from designated Ploggs
automatically to a PC.

The comprehensive Software Development Kit (, including the Plogg
Manager DLL, provides software engineers with the capability to integrate the
Plogg and data retrieval functions seamlessly into larger Wireless Sensor

"A number of customers throughout Europe and North America have requested
that we upgrade the Plogg to provide better integration options," said Shaun
, General Manager, "The ZigBee PRO version now offers this advantage
and is compatible with previous ZigBee versions."
