Gateway M-Bus - KNX
GATEWAYS
Description
The Ekinex® M-Bus - KNX Gateway performs a protocol conversion between an M-Bus
and a KNX TP network. The device acts as M-Bus master. Versions for networks
with a maximum number of 20, 40, 80 and 160 connected M-Bus slave devices are
available. The device integrates a KNX bus communication module and it is suitable
for mounting on a 35 mm DIN rail; it requires an auxiliary power supply.
Main features
• Plastic casing
• Connection to bus line with KNX terminal block
• Installation on 35 mm rail (according to EN 60715)
• 4 modular units (1 MU = 18 mm)
• IP20 protection degree (installed device)
• Weight 145 g
Technical data
• Power supply: from M-Bus network
• Absorption at 24 Vdc: 3,5 VA (without load);
4, 5, 8 or 14 VA (resp. with 20, 40, 80 or 160 M-Bus devices)
Communication
KNX side
• KNX TP (Twisted Pair) communication port electrically isolated from power supply
• Baud rate 9600 baud
• 1440-byte volatile support “KNX image” memory buffer
M-Bus side
• M-Bus communication port (wired version, two-pole cable)
• Selectable baud rate from 300 to 9600 baud
• Device addressing from 1 to 250
• Variable reading through M-Bus slave device mapping
• 1440-byte volatile support “M-Bus image” memory buffer
Configuration
• Ethernet communication port (IEEE 802.3), RJ45 connector, minimum cable
category: 5E
Delivery
The delivery includes the device and terminal blocks to connect to the KNX bus.
Other information
M-Bus (Meter-Bus) is a standard protocol for remote reading of data acquired from
thermal energy, electricity, gas and water meters. M-Bus is fully compliant with EN
13757: Communication Systems for remote meter reading, parts 2 (Physical and
connection layer) and 3 (Application layer).
