1 Description

Introduction

This document describes the integration of M-Bus meters with KNX home automation systems using the gateway
IntesisBox KNX - M-Bus.

The aim of this integration is to make accessible M-Bus devices signals and resources from a KNX network, as if it
was a part of the own KNX system and vice-versa. To do it so, IntesisBox performs as a one more KNX device,
sending and receiving telegrams to group addresses in the KNX network.

IntesisBox incorporates and embeded M-Bus level converter, so no extra hardware is required.
Configuration is carried out using the configuration software IntesisBox® MAPS.
This document assumes that the user is familiar with KNX and M-Bus technologies and their technical terms.

Functionality

IntesisBox polls, either continuously or only when ordered from the KNX, the M-Bus devices to obtain updated
readings for the points configured in it (the points corresponding to measures and states of the meters in the
integration points list explained later in this document). With every read, the new values received are updated in the
Intesisbox's memory and become updated in the KNX side. When a change in any point configured as write-enabled
in IntesisBox is detected (this is written from the KNX side), the corresponding action in the M-Bus device will be
performed. These actions can be: force a polling of a specific M-Bus device or force a polling of all M-Bus devices.

The polling of a specific M-Bus device, or of all M-Bus devices, can be forced in any moment from KNX side by
writing a 1 in the corresponding KNX object specially enabled for this purpose in the IntesisBox.

The automatic continuous polling of all M-Bus devices can be activated/deactivated writing from KNX in a specific
KNX object specially enabled for this purpose in the IntesisBox.

Other M-Bus information accessible from KNX, using specific KNX objects of the IntesisBox, is:

• Bus activity (indicates if meters are currently being polled or if polling is in stand-by).

• M-Bus status of every meter (this M-Bus status is sent by the own meter with every poll and indicates the

internal status, manufacturer specific in every case).

These are the main features of the M-Bus interface of IntesisBox:

• Embedded level converter. Direct connection to M-Bus devices with no extra hardware required.

• Scan option to automatically detect M-Bus devices and its available registers.

• Import/Export of M-Bus device templates.

• MBUS-/+ two wires (plug-in terminal bloc with screws) connection.

• Baud rate configurable from 300 to 9600 bps (allowed baud rates in M-Bus. The devices are normally

configured at 2400 bps at the factory).

• Primary or secondary addressing allowed.

• Useful timeouts and specific parameters to make the interface widely compatible with many meter's

peculiarities found usually between different manufacturers.

• Polling of the meters can be continuously, either configured in the own IntesisBox or you can
activate/deactivate continuous polling of the meters from KNX side using a special datapoint.

• You can force a polling of the meters (refresh of readings) in any moment from KNX side using special
datapoints: one datapoint to force a polling of all the meters, and one specific datapoint per meter to force
the polling of the individual meter.

• IntesisBox can also be configured to make a single polling of the meters (refresh of readings) at start up.

• For each meter, a datapoint is available in KNX indicating communication error with the meter, also a general

communication error datapoint is available (that will be active whenever the communication with one or
more meters has failed).

• Fully flexible configuration of the registers to poll in the meter, to adapt to any meter.

Every meter, depending on manufacturer and model, offers different type of signals from the mentioned before. To
know what signals offers the meter and of what type, to be able to integrate those wanted, refer to the device technical
documentation. Anyway, and to ease and speed up the identification of the signals offered by any device (and of
what type), the scan option is highly recommended or the import of templates too.

2 KNX System

In this section, a common description for all IntesisBox KNX series gateways is given, from the point of view of KNX
system which is called from now on internal system. Connection with the MBUS system is also called from now on
external system.

Description

IntesisBox KNX connects directly to the KNX TP-1 bus and performs as one more device into the KNX system, with
the same configuration and operational characteristics as other KNX devices.

Internally, the circuit part connected to the KNX bus is opto-isolated from the rest of the electronics.
IntesisBox KNX receives, manages and sends all the telegrams related to its configuration to the KNX bus.
When a change in a signal of the external system is detected, a WRITE telegram is sent to the KNX bus (addressed

with the group address associated to the corresponding group object), in order to maintain both systems synchronised
in every moment.

The status of the KNX bus is checked continuously and, if a bus drop-down is detected, for example due to failure in
the bus power supply, after the KNX bus is restored again, IntesisBox will send READ telegrams to group addresses
of all communication objects marked with flag ‘Ri’. The behaviour of each individual point into IntesisBox is
determined by the flags configured for the communication object. See details below.

Points definition

Every KNX object in configuration has following KNX properties:

Property

Description

Description

Descriptive information about the communication object or signal.

Object
function

Information on range of values for the group object.

DPT

Datapoint type. It is the KNX data type used to encode the signal's value. It will depend
on the type of signal associated in the external system in every case.

Group

It is the KNX group to which the point is associated. It is also the group to which the
read (R), write (W), transmit (T), update (U) and read on init (Ri) flags are applied. It is
the sending group.

Listening
addresses

They are the addresses that can write on the group object, apart of the main group
address.

R

Read. If this flag is activated, READ telegrams of this group address will be accepted.

Ri

Read on Init. If this flag is activated, the object will trigger corresponding READ request
(on associated group address) on initialization.

W

Write. If this flag is activated, WRITE telegrams on this group object will be accepted.

T

Transmit. If this flag is activated, when the group object value changes, due to a change
in the external system, a WRITE telegram of the associated group address will be sent
to the KNX bus.

U

Update. If this flag is activated, UPDATE telegrams (response to READ telegrams) on
this group object will be accepted.

Active

If activated, the point will be active in IntesisBox, if not, the behaviour will be as if the
point is not defined. This allows deactivating points without the need of delete them for
possible future use.

These properties are common for all IntesisBox KNX series gateways. Although each integration may have specific
properties according to the type of signals of the external system.

3 Connections

Find below information regarding the IntesisBox connections available.

Power Supply

Must use NEC Class 2 or Limited Power Source (LPS) and
SELV rated power supply.

Respect polarity applied of terminals (+) and (-). Be sure the
voltage applied is within the range admitted (check table
below). The power supply can be connected to earth but only
through the negative terminal, never through the positive
terminal.

Ethernet / Console (UDP & TCP)

Connect the cable coming from the IP network to the
connector ETH of the gateway. Use an Ethernet CAT5 cable.
If communicating through the LAN of the building, contact the
network administrator and make sure traffic on the port used
is allowed through all the LAN path (check the gateway user
manual for more information). Default IP is 192.168.100.246.
DHCP is enabled by default.

PortA / KNX

Connect the KNX TP-1 bus to connectors A3 (+), A4 (-) of
gateway’s PortA. Respect the polarity.

PortB / M-Bus

Connect the MBUS to connectors B1 (M-), B2 (M+) of
gateway’s PortB. Respect the polarity.

Console Port
Connect a mini-type B USB cable from your computer to the gateway to allow communication between the
Configuration Software and the gateway. Remember that Ethernet connection is also allowed. Check the user manual
for more information.

USB

Connect a USB storage device (not a HDD) if required. Check the user manual for more information.

Ensure proper space for all connectors when mounted (see section 6).

Powering the device

A power supply working with any of the voltage range allowed is needed (check section 5). Once connected the RUN
led (Figure above) will turn on.

WARNING! In order to avoid earth loops that can damage the gateway and/or any other equipment connected to it,
we strongly recommend the use of DC power supplies, floating or with the negative terminal connected to earth.

Never use a DC power supply with the positive terminal connected to earth.

Connection to KNX

Connect the KNX TP1 bus to connectors A3 (+) and A4 (-) of gateway’s PortA. Respect the polarity.

Connection to M-Bus

The gateway connects to the M-Bus system directly without requiring any external RS232 or RS485 to M-Bus level
converter.

Connect the M-Bus bus to connectors B1 (M-) and A2 (M+) of gateway’s PortB.
Remember that the IntesisBox provides 36VDC M-Bus voltage to the bus, acting as a M-Bus level converter as well.
In case there is no response from the M-Bus device(s) to the frames sent by IntesisBox, check that they are operative

and reachable from the network connection used by IntesisBox. You can use an EIA-485-to-USB converter and a M­Bus Master software (such as MBSheet or similar) to double check the M-Bus installation.

Connection to the configuration tool

This action allows the user to have access to configuration and monitoring of the device (more information can be
found in the configuration tool User Manual). Two methods to connect to the PC can be used:

• Ethernet: Using the Ethernet port of IntesisBox.

• USB: Using the console port of IntesisBox, connect a USB cable from the console port to the PC.
