Description
Introduction
IntesisTM KNX –Mitsubishi Heavy Industries AC is a communication gateway for the
integration of Mitsubishi Heavy Industries air conditioning (AC) systems into KNX TP-1
(EIB).
This gateway allows integrating a Mitsubishi Heavy Industries AC system inside a
supervision/control/automation system through PLC, SCADA and, in general, through any
device or system with a KNX TP-1 (EIB) interface.
The aim of this integration is to make accessible several Mitsubishi Heavy Industries air
conditioning indoor units communicating with the Superlink protocol as if they were part of
a KNX TP-1 (EIB) system. Therefore, the IntesisTM KNX acts as a KNX device in the KNX TP-
1 (EIB) interface, allowing the KNX system read and write in the communication objects.
Moreover, IntesisTM includes all hardware required to manage/control Mitsubishi Heavy
Industries indoor units without extra components needed.
Integration signals
Following is the list of parameters that can be monitored/controlled on the indoor units
using IntesisTM:
▪For each indoor unit in the system:
oCommunication Status (read-only)
oOn/Off (R/W)
oOperation Mode (R/W)
oSetPoint Temperature (R/W)
oFan Speed (R/W)
oRemocon Lock/Unlock (R/W)
oLouver Control (R/W)
oRoom Temperature (read-only)
oFilter Sign Status (read-only)
oError Code (read-only)
oCompressor Status (read-only)
oFilter Sign Reset (write-only)
oRemocon Error Reset (write-only)
oThermo On/Off Status (read-only)
Apart from these, the IntesisTM also implements some extra signals (functions):
▪For all indoor units
1
in the system:
oHW Communication Status (read-only)
oOn/Off (write-only)
oOperation Mode (write-only)
oSetPoint Temperature (write-only)
oFan Speed (write-only)
oRemocon Lock/Unlock (write-only)
1
These signals work as master signals controlling all connected units at the same time

Functionality
IntesisTM continuously polls (reads) the Superlink network for all configured signals and
keeps the updated status of all of them in its memory ready to be served when requested
from KNX.
When a change of status is detected in a MHI’s AC signal, a write telegram is sent to the
KNX bus, of the associated KNX Group.
When it is received a telegram from the KNX bus, and if its KNX Group address is associated
to an MHI’s AC signal, a message is sent immediately to the Superlink network to perform
the corresponding action in the MHI’s AC system.
In the continuous polling if no response is detected, the corresponding virtual signal inside
the gateway will be activated indicating communication error. There is a virtual signal for
each AC indoor unit indicating communication error with the indoor unit –this signal will be
normally activated if the indoor unit is not properly setup.
Each of the mentioned signals in section 1.2 has to be associated to a KNX group address,
with this, all the system is seen as another KNX device, with the same configuration and
functioning characteristics. These addresses are not fixed and can be configured using the
LinkBoxEIB tool (see 4.2.2)
IntesisTM includes all hardware needed to connect directly with the Mitsubishi Heavy
Industries indoor units connecting with Superlink network.

KNX interface of IntesisTM
Description
IntesisTM KNX - Mitsubishi Heavy Industries supports the KNX TP-1 (EIB) physical layer, as
defined in the KNX standard. It behaves as another device of the KNX system, with the
same configuration and functional characteristics as other KNX devices.
KNX TP-1 (EIB) bus provides a 30V DC current, which can even directly power certain low-
consumption KNX devices. IntesisTM does not drain any significant current from the KNX bus
- it has a separate own power supply. Another important electrical aspect is that the KNX
TP-1 (EIB) port of IntesisTM is optically isolated (~2500Vrms AC) from all its other ports
(EIA232, EIA485, Ethernet) and power supply.
At a logical level, all KNX devices feature an interface of communication objects, by which
their functionality is abstracted. As a basic example, a KNX interface of an AC indoor unit
would typically consist of an interface of datapoints such as “On/Off”, “Setpoint
temperature”, “Operating mode”, etc.
Associations between communication objects from different KNX devices are actually done
by means of so-called group addresses.
KNX telegrams within a working KNX installation are always addressed to a certain KNX
group address. Typically, whenever a communication object on a KNX device changes its
value, the new value is updated to the bus, by sending a “write” telegram addressed to its
associated group address. The rest of KNX devices in the installation that have a
communication object associated to this group address will act accordingly on reception of
the new value.
Other operations are possible. KNX devices can also decide to read the current value of the
communication objects, by sending a “read” telegram to a certain group address (previously
known to be associated to the targeted comm. object). This operation is performed by many
devices on bus start-up or recovery –in this way, the device gets the latest value of the
group addresses it has associated right from its start-up.
Each datapoint defined in IntesisTM KNX configuration needs at least a single KNX group
address associated with it. This group address will be used either for sending updates to
KNX of the datapoint value (that have been generated on the other MHI interface of the
IntesisTM), or receiving updates from KNX of the datapoint value (that will be propagated to
the MHI side in this case)
From the point of view of KNX functionality, each datapoint of IntesisTM can hold following
group address associations:
•A single KNX group address with which update/write telegrams will be sent,
whenever the datapoint changes (as a result of a change coming from the other
interface of IntesisTM, MHI in this case).
•One or more KNX group addresses from which this datapoint of IntesisTM will be
updated/written from the KNX installation (resulting in a change to the other side of
IntesisTM, MHI in this case).
A single KNX group address from which IntesisTM will read the object value on KNX bus
recovery / IntesisTM start-up.

Behavior of IntesisTM datapoints with regard to their associated group addresses is defined
by means of flags (R, W, T, U and U2), explained in section 4.2.2.
Additional to the binding aspect commented above, it is also important to notice that each
KNX communication object has a defined EIS type. The EIS type of a communication object
defines the bit length and coding of the data it represents. Communication objects
associated by means of a group address need to match the same EIS type, in order to
communicate consistently.
So, at configuration time it is required that for each datapoint configured on IntesisTM an EIS
type is defined. Datapoints on IntesisTM KNX support the following EIS-types:
•EIS1 - Switching (1bit raw)
•EIS2 - Dimming (4bit raw)
•EIS5 –Value (16bit –floating type)
•EIS6 –Scaling (8bit –scaled 0%-100% in values 0-255)
•EIS7 –Drive Control (1bit raw)
•EIS8 –Priority (2bit raw)
•EIS9 –IEEE 754 float (32bit –floating type)
•EIS10 –16bit Counter (16bit raw)
•EIS11 –32bit Counter (32bit raw)
•EIS13 –ASCII char (8bit raw)
•EIS14 –8bit Counter (8bit raw)
ETS3 or ETS4 software tools are not used to configure IntesisTM. Though, it’s typical that the
choice of which KNX group addresses to use is restricted or defined by an ETS-based
project. If that’s the case, the KNX installer/integrator needs to provide the set of group
addresses prior to doing the configuration of datapoints in LinkBoxEIB.
Also, a dummy ETS application is provided by HMS Networks (section 5), which can be
imported into ETS. This application is nor downloadable into IntesisTM KNX neither usable for
IntesisTM configuration. Rather, it poses as a means of having a device in the ETS project
representing the IntesisTM KNX and its own datapoints/communication objects, and to which
group addresses are associated.
Communication objects available
Address map is configurable for each indoor unit and can be modified through the supplied
software LinkBoxEIB. Next, there are two tables showing different
datapoints/communication objects available either for each indoor unit control or all indoor
units control at a time. Please, remember that in the tables R/W stands for Read and Write,
Rstands for Read Only and Wstands for Write Only.

LinkBoxEIB. Configuration & monitoring tool for IntesisTM KNX series
Introduction
LinkBoxEIB is a Windows®compatible software developed specifically to monitor and
configure IntesisTM KNX series.
The installation procedure and main functions are explained in the LinkBoxEIB User Manual.
This document can be found in the Doc folder or can be downloaded from the link indicated
in the installation sheet supplied with the IntesisTM device.
In this section, only the specific case of Mitsubishi Heavy Industries indoor unit’s integration
to KNX networks will be covered.
Connections configuration
To configure the IntesisTM connection parameters and to see the points list, press on the
Config button in the menu bar (see Figure 4.1). The Mitsubishi Heavy Industries
Configuration window will open (see Figure 4.2). For integrations with large number of
points, there is available an alternative CSV installation procedure explained in the
LinkBoxEIB User Manual.

x in “Indoor Unit xxx”) is the reference that will be used later on (in tab “Signals”)
to refer to this AC indoor unit. You can also change the description name of the
Indoor Unit and its address to facilitate integration tasks using Add and Name
text boxes.
2. Add: Enter here the desired Indoor Unit address.
3. Name: Enter here the desired descriptive Indoor Unit name (optional).
4. KNX Datapoint type for HVAC Mode communication object: Select the
desired codification so the Mode object matches your integration needs.
5. Gateway version: Selection of the IntesisTM KNX –Mitsubishi Heavy Industries
gateway you are setting up (128AC for INKNXMHI128O000, 48AC for
INKNXMHI048O000).
6. Timeout response: Maximum amount of time permitted before activating the
Communication Error signal. It is expressed in milliseconds (ms) and ranges can
vary from 2000 ms to 10000 ms.
7. Delay interframe: Maximum amount of time permitted between End Of
Transmission (EOT) and a new frame. It is expressed in milliseconds (ms) and
ranges can vary from 500 ms to 3000 ms.
8. Monitoring cadence: Cadence of monitoring and subscription. It is expressed in
seconds (s) and ranges can vary from 60 s to 600 s.
9. Virtual ambient temperature and setpoint: Meant to be enabled when you
want the temperature provided by a KNX sensor to be the reference ambient
temperature for the air conditioner. Then, the following formula applies for
calculation of real Control_ Setpoint Temperature sent to the AC unit:
As an example, consider the following situation:
User wants: 19ºC (“KNX Setp. Temp.”)
User sensor (a KNX sensor) reads: 21ºC (“KNX Amb Temp.”)
Ambient temp. read by MHI system is: 24ºC (“AC Ret. Temp”)
In this example, the final setpoint temperature that INKNXMHI048O000/128 will
send out to the indoor unit (shown in “Setp. Temp.”) will become 24ºC – (21ºC -
19ºC) = 22ºC. This is the setpoint that will actually be requested to MHI unit.
This formula will be applied as soon as the Control_ Setpoint Temperature and
Control_ Ambient Temperature objects are written at least once from the KNX
installation. After that, they are kept always consistent.
Note that this formula will always drive the AC indoor unit demand in the right
direction, regardless of the operation mode (Heat, Cool or Auto). Due to the use
of this functionality, temperature showed in the KNX device and in the MHI remote
controller (in case it exist) may differ.
“AC Setp. Temp” = “AC Ret. Temp” - (“KNX Amb. Temp.” - “KNX Setp. Temp”)
▪AC Setp. Temp: AC indoor unit setpoint temperature
▪AC Ret. Temp: AC indoor unit return temperature
▪KNX Amb. Temp.: Ambient temperature provided from KNX
▪KNX Setp. Temp: Setpoint temperature provided from KNX

Additional configuration parameters should generally be left to their default value. They only
might need to be tuned in some very specific cases (installations with large number of units,
scenarios with large bursts of commands sent at once …)
4.2.2 Signals
Select the Signals tab to configure the signals list (the IntesisTM internal points).
Figure 4.6 Signal list
1. IU:Indoor Unit identifier.
2. Property:Identifies the different signals available per every MHI group. An
identification code is given to every different signal into the MHI group, identifying
every signal with an individual code. In section 2.2, an explanation of every signal
is given. A contextual menu appears using mouse right button click over the
column showing all the possible signal codes.
3. Signal: Signal's descriptive name (optional). Useful to identify the signal. The
default descriptive name corresponds to the signal's code, but can be edited or
modified.
4. EIS: KNX data type (Data point) to encode the signal’s value. It will depend on
the MHI type of signal associated to it in every case. Edit using the mouse right-
button-click pop-up menu available on the column. Only the EIS defined in values
are allowed.
5. Group: Main KNX group address for the signal. Flags R,W,T,U explained below will
only apply for this main KNX group address, not for listening addresses. Formats
supported are P/I/S and P/S.
6. Listening addresses: KNX group addresses that will be listened by IntesisTM for
this signal. If IntesisTM receives a KNX telegram whose destination is one of these
listening addresses, the telegram will be taken into account and the corresponding
action will be performed on this signal (if W is active). Formats supported are
P/I/S and P/S, comma separated.
7. Communication object flags:
7.1 R: Indicates if this signal is allowed to be read from KNX system (“R” flag
activated, “blank” flag not activated).

7.2 W: Indicates if this signal is allowed to be written from KNX system (“W”
flag activated, “blank” flag not activated).
7.3 T: Indicates if this signal will generate a telegram sending to the KNX
system following a change of the signal’s value, that is to say, any change
of value of this signal in MHI side will be transmitted to the KNX system if
this flag is activated (“T” flag activated, “blank” flag not activated).
7.4 U: Indicates if this signal will be updated (sending read requests)
whenever IntesisTM starts up or after a KNX bus reset (“U” flag activated
for the main group address, “U2” activated for the listening group
address, “blank” flag not activated).

8. Active: Indicates if the signal is active or not for the current configuration (“1-
Yes” signal active, “0-No” signal not active).
See section 2.2 for further detail on available signals and the possible values on each one.
Sending the configuration to IntesisTM
When the configuration is finished, follow the next steps.
1.- Click on Save button to save the project to the project folder on your hard disk
(more information in LinkBoxEIB User Manual).
2.- You will be prompted to generate the configuration file to be sent to the gateway.
a.- If Yes is selected, the binary file (MHI.Lbox) containing the configuration
for the gateway will be generated and saved also into the project folder.
b.- If NO is selected, remember that the binary file with the project needs to
be generated before the IntesisTM starts to work as expected.
3.- Once in the configuration window again, click on exit. Configuration file is ready
to be sent to the IntesisTM device.
4.- Press the Send File button to send the binary file to the IntesisTM device. The
process of file transmission can be monitored in the IntesisTM Communication
Console window. IntesisTM will reboot automatically once the new configuration is
loaded.
After any configuration change, do not forget to send the configuration file
to the IntesisTM using button Send File.
Signals viewer
Once the gateway is running with the correct configuration, to supervise the status of the
configured signals, press the Signals button on the menu bar (see Figure 4.1). The Signals
Viewer window will open (see Figure 4.7).
This window shows all signals active within the gateway with its main configuration
parameters and its real time value
2
in the Value column.
1
DO NOT BE CONFUSED: Philosophy of IntesisTM point's U flag is not the same as KNX device's U flag. In KNX
devices, U flag means that the point's value will be updated whenever a write telegram for the group address is
received by the device.
2
In case you connect to the IntesisTM when it’s been running for a certain time, you should press the Refresh
button to get updated values. After pressing Refresh, all signal values will keep continuously updated until the
connection is closed.

Figure 4.7 LinkBoxEIB Signals Viewer
The signals viewer can be used even though only one system is connected to the IntesisTM,
KNX or Mitsubishi Heavy Industries AC. Therefore, it becomes convenient for supervision
and testing the system.
In order to force a specific value to a signal, double-click its row in the table. This will
display a dialog in which the desired value can be entered (see Figure 4.8). Changing its
value in this way, will make:
•The content of the corresponding KNX group address will be changed to this value.
•If the signal is write-enabled, it will trigger a suitable command to Mitsubishi Heavy
Industries AC system.
