What is HWg-PWR 3 / 12 / 25
The 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 also allows reading value names, units of measurement, or tariff
information from the meters. The user can customize all of these data (e.g. change the unit of
measurement or its exponent).
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

HWg-PWR connects directly to a 110/230VAC 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 blue M-Bus LED indicates communication over the M-Bus.
2) Configuring the IP address –UDP
