What is HWg-PWR
HWg-PWR is an Ethernet-enabled device for remote monitoring and metering of
electricity, heat, water or gas consumption using electricity, water, gas, heat, or other
meters equipped with the M-Bus interface. In addition to metering, the device also
supports alarming through e-mail or SNMP traps whenever allowed values are exceeded.
HWg-PWR is designed for remote reading of values from meters equipped with the M-Bus
interface. Each meter can provide multiple variables, depending on the meter type and
model. Typically, electricity meters provide the total electricity consumption and also the
immediate value at the time of reading, line voltage and/or line current; water meters
indicate total water consumption as well as immediate consumption or liquid flow rate;
and so on.
Note: HWg-PWR is designed to be universal; hence, all discovered values are read out
from every connected meter, until a specified limit is reached. To improve user comfort, it
is possible to enable or disable each discovered value (disabled value is hidden from view),
and to turn on or off the recording of measured readings for each enabled value (in order
to increase the available recording time for the remaining values).
The M-Bus protocol allows to read value names, units, or tariff information from the
meters. The user can customize all of these data (e.g. change the unit of measurement or
its multiplier).
Usage examples
Remote monitoring of electricity meters in small server rooms and BTS
Monitoring of energy consumption in rented premises
Reading out energy consumption in remote or inaccessible areas
Control over energy costs
Checking for individual line overloads in three-phase wirings
Checking for undervoltage in electric wirings
Monitoring the flow of liquids

Description of connectors and connections
LED indicators
Power (green) – lights up when the device is powered.
Alarm (red) – lights up whenever a monitored variable is in alarm.
M-Bus (blue) – flashes whenever M-Bus communication takes place.
Status (green) – HWg-PWR status
o Solid on – HWg-PWR is in regular operation
o Slowly flashing – HWg-PWR is starting up
o Rapid flashing – firmware is being uploaded
Link (amber) – flashing indicates activity on the Ethernet interface.
Restoring factory defaults
Press and hold the Default Switch button, connect power, and hold the button pressed for
10 more seconds. HWg-PWR resets itself to factory defaults. Be careful when working
with HWg-PWR in a distribution box.

First steps
1) Connecting the cables
HWg-PWR connects directly to a 230VAC supply; therefore, it should be installed by
qualified personnel only!
Connect the unit to the Ethernet (a patch cable to a switch, or a cross-over
cable to a PC).
Connect the M-Bus with meters. Pay attention to the polarity!
Connect HWg-PWR to the electrical network.
The green Power LED lights up.
If the Ethernet connection works properly, the LINK (amber) LED lights up after
a short while, and then flashes whenever data transfer takes place (activity
indication).
After power up, the amber LINK LED flashes rapidly to indicate IP address
negotiation over DHCP.
The green M-Bus LED indicates communication over the M-Bus.
2) Configuring the IP address – UDP
Config
UDP Config utility – root directory of the
supplied CD (Windows and Linux versions).
Available for download at www.HW-
group.com, Software > UDP Config.
Click the icon to launch UDP
Config. The program
automatically looks for connected
devices.
To search for devices, click the
Find Devices icon.
The program searches for devices on your local
network. Double-click a MAC address to open a
basic device configuration dialog.
Configure the network parameters
IP address / HTTP port (80 by default)
Network mask
Gateway IP address for your network
Device name (optional)
Click the Apply Changes button to save the
settings.

Restoring factory defaults
Right-click a device MAC address. Within 60 seconds after powering up the unit,
factory defaults can be restored using UDP Config.
Disconnect the power jack, connect the jumper near the RJ11 sockets, power up
the device and wait for 15 seconds. Then, disconnect the power and disconnect
the jumper. The device is ready in its factory default configuration.
3) WWW interface of the device
