HWg-PWR: M-Bus IP energy meter (SNMP, WEB) HW group
www.HW-group.com page 24
Secondary Address – Secondary address on the M-Bus. This address is used to
identify a meter if there are more meters with the same primary address ( Address
field) on the bus. Secondary Address is non-editable and consists of a
manufacturer-defined part and the Address field (last 2 characters).
Medium – Type of the meter (electricity, gas …). The medium is not editable.
Enable – Enables or disables the meter within HWg-PWR. When a meter is
disabled, values are not detected or read but the configured parameters remain
stored. This can be used to temporarily turn off the reading and recording for a
meter (during maintenance etc.)
Address – Primary address on the M-Bus. The address is entered as one byte
(0-255).
Serial Baudrate – M-Bus communication speed for the particular meter. By
default, 2400 Baud is configured. Meters with different communication speeds
can coexist on a single bus; this parameter sets the speed for a particular meter.
Serial Parity – M-Bus communication parity. As with the baudrate, parity can be
specified individually for each meter.
Name – Meter name. Identifies the meter within HWg-PWR – in graphs, XML and
SNMP.
Scan Value – Reads out the values and their parameters from the meter. See First
Steps .
Parameter Table section
The Parameter Table section displays information about discovered values from a
particular meter – their names ( Name ), units of measurement ( Unit ) and current readings
( Value ). Each value is assigned a unique ID within HWG-PWR for use in XML and SNMP
communication. To edit a value, its parameters and properties, click “ Edit ” on the
corresponding line.
