HRW HPE-BNMBUS Manual

HPE-BNMBUS –
FW 4.01, from March, 2018
250 point integration of M-Bus (EN1434-3) conforming devices in to BACnet MS/TP networks. Up to 40
M-Bus devices may be connected to the gateway for read access of up to 250 M-Bus data-points
Typical Applications
BACnet MS/TP network integration of M-Bus devices:

Hot water or chilled water energy meters (BTU meters)

Water meters

Electricity meters

Pulse converters
Feature Summary

Integrated M-Bus network driver, up to 40 M-Bus devices

Primary or Secondary addressing

Diagnostic function for M-Bus point DIF/VIF identification

With or without common 'DVIF' data point assigned to each device address configuration point

Beyond the device address point DVIF assignment, independent point configuration per-device

M-Bus point DIF-only scan option possible (independent of point VIF value)

Settable network scan period (for suitable battery powered meters, battery conservation)
Default M-Bus Settings
The gateway may be configured for any M-Bus device. As an initial guide (example) the factory settings
include meter and point addressing for the Sontex SuperCal 531 energy integrator. Ultimately the user
must configure the meter and point data base to suit the specific devices connected in the M-Bus
network.
Sontex SC531 example points:

Primary address 0

Common DVIF for Energy (kWh, assigned to the Primary address point, point 4 / AV4)

Volume at point 5 (AV5)

Flow temperature at point 6 (AV6)

Return temperature at point 7 (AV7)

Power (kW) at point 8 (AV8)

Flow rate (m 3 /h) at point 9 (AV9)
