Description
Introduction
IntesisTM Modbus Server –Mitsubishi Heavy Industries AC is a communication gateway for
Mitsubishi Heavy Industries air conditioning (AC) systems to Modbus slave (RTU and TCP).
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 Modbus mastering (TCP or RTU) 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 Modbus system. Therefore, the IntesisTM Modbus Server acts as a Modbus slave in the
Modbus interface, allowing the Modbus master read and write in the Modbus registers.
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)
oRemote Controller 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)
oRemote Controller 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)
oRemote Controller Lock/Unlock (write-only)
1
These signals work as master signals controlling all connected units at the same time

Functionality
Each of the mentioned signals in section 1.2 is associated to a predefined and fixed Modbus
address. Therefore, all the system is seen as a single Modbus slave unit with a fixed Modbus
address map from the Modbus system point of view.
Two Modbus mode connection types can be active in IntesisTM: Modbus RTU or Modbus TCP,
or both simultaneously.
IntesisTM continuously polls all signals provided by each indoor unit and maintains the
updated values to be served in Modbus.
In the continuous polling of each indoor unit, if no response of a certain device is detected,
the corresponding virtual signal inside the gateway will be activated indicating
communication error between the gateway and that precise device (see 0).
When a write order is done from Modbus in a gateway's write-enabled Modbus address, the
corresponding order is sent to the associated Mitsubishi Heavy Industries signal (Superlink).
Each Mitsubishi Heavy Industries Indoor Unit has a unique address (0 to 127). These
addresses need to be configured inside IntesisTM using the LinkBoxMB tool (see 4.2.2).
IntesisTM is capable of managing up to two simultaneous Modbus master connections.
IntesisTM includes all hardware needed to connect directly with the Mitsubishi Heavy
Industries indoor units connecting with Superlink network.

Figure 4.4 Mitsubishi Heavy Industries interface configuration
1. Devices: In this list, you can individually enable each of the 128 indoor units
available on the system. The index in the column “Indoor unit” (i.e. the number 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 name of the indoor Unit to
facilitate integration tasks.
2. Gateway version: Selection of the Intesis Modbus Server –Mitsubishi Heavy
Industries gateway you are setting up. (128AC for INMBSMHI128O000, 48AC for
INMBSMHI048O000)
3. 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.
4. 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.
5. Monitoring cadence: Cadence of monitoring and subscription. It is expressed in
seconds (s) and ranges can vary from 60 s to 600 s.
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 Modbus map tab
In order to know the Modbus map that is going to be used by the interface, the Modbus
map tab can be consulted.

Figure 4.5 Modbus signal list
1. Address Formula: Formula used by IntesisTM to define the Modbus address for
the point. Use this address (obtained with this formula) to access the point from
your Modbus master device.
2. R/W:Indicates if the signal is read-only, or if it can be read and written (from the
Modbus system point of view).
3. Signal: Signal description.
4. Values: Possible values for the signal.
See section 2.5 for further detail on address mapping and the possible values on each
signal.
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 LinkBoxMB 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. Intesis 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 4.6).
This window shows all signals active within the gateway with its main configuration
parameters and its real time value
1
in the Value column.
Figure 4.6 LinkBoxMB Signals Viewer
The signals viewer can be used even though only one system is connected to the IntesisTM,
Modbus 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 4.7). Changing its
value in this way, will make:
•The content of the corresponding Modbus 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.

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.

Files
LinkBoxMB saves the integration configuration in the following files inside the project folder:
PROJECT.INI
INI file containing general information related to the project
MHI.INI
INI file containing information related with the values configured
through the “Connection” tab in IntesisTM configuration
MHI.LBOX
Binary file created from the information in the files described
above. This is the file downloaded to the IntesisTM.
Table 4.1 LinkBoxMB generated files during Project creation
It is strongly recommended to back up the project folder containing these files in external
media, once the installation process is finished. This way you will be able to do future
configuration changes in case of reinstallation of LinkBoxMB due, for example, to a failure of
the hard disk in the PC where LinkBoxMB was installed.
The configuration cannot be uploaded from the gateway to LinkBoxMB, it can only
be downloaded.
