Description1.
Introduction1.1
IntesisBox®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 IntesisBox®Modbus Server acts as a Modbus slave in the
Modbus interface, allowing the Modbus master read and write in the Modbus registers.
Moreover, IntesisBox®includes all hardware required to manage/control Mitsubishi Heavy
Industries indoor units without extra components needed.
Integration signals1.2
Following is the list of parameters that can be monitored/controlled on the indoor units
using IntesisBox®:
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 IntesisBox®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

Functionality1.3
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 IntesisBox®: Modbus RTU or Modbus
TCP, or both simultaneously.
IntesisBox®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 IntesisBox®using the LinkBoxMB tool (see 4.2.2).
IntesisBox®is capable of managing up to two simultaneous Modbus master connections.
IntesisBox®includes all hardware needed to connect directly with the Mitsubishi Heavy
Industries indoor units connecting with Superlink network.

Table 1.1 IntesisBox®capacity
* There are two different models of IntesisBox®Modbus Server –Mitsubishi Heavy
Industries AC each one with different capacity. The table above shows the capacity for the
top model (with maximum capacity).
Their order codes are:
MH-AC-MBS-48:
Model supporting up to 48 indoor units
For Superlink-I (Previous Superlink) or Superlink-II (New Superlink).
Indoor Unit actual address range is 00 to 47
MH-AC-MBS-128:
Model supporting up to 128 indoor units
For Superlink-II (New Superlink)
Indoor Unit actual address range is 000 to 127
Check available combination of Mitsubishi Heavy Industries Central Control and BMS
interface units in the next tables.
In the case of SL2NA or SL3NA, it is necessary to erase registration of non-connected indoor
unit. For SL2NA and SL3NA, change is required for the setup deprived of the rights of
instruction of Remocon control Lock/Unlock.

Modbus interface of IntesisBox®2.
Description
2.1
IntesisBox®acts as a slave device in the Modbus interface. The physical interface can be
either Ethernet, if using Modbus TCP, or the EIA485 (or EIA232), if using Modbus RTU.
Functions supported2.2
This part is common for Modbus RTU and TCP:
Modbus functions 03 and 04 (read holding registers and read input registers) can
be used to read Modbus registers.
Modbus function 06 (Single Multiple Holding Registers) must be used to write
Modbus registers.
As per Modbus standard specification, register contents are always expressed in
MSB..LSB (Bid Endian).
Modbus error codes are fully supported, they will be sent whenever a non-valid
Modbus action or address is required (see section 9).
Modbus RTU2.3
Baud rate can be selected from 1200, 2400, 4800, 9600, 19200 and 38400.
Information structure:
Data Bits: 8
Parity Bit: Selectable from non, even, odd or second stop bit (2stop).
Stop Bit: 1
Modbus slave number can be configured.
Physical connection (EIA232 or EIA485) can also be selected.
Only the lines RX, TX and GND of the EIA232 connector are used (TX and RX for EIA485).
Modbus TCP2.4
The TCP port to use can be configured (by default 502 is used).
The IP address, subnet mask and default gateway address to use by IntesisBox®can be
also configured.
Address Map2.5
Address map is fixed for each indoor unit and can be consulted as explained in the following
tables. Please, remember that in the tables R/W stands for Read and Write, Rstands for
Read Only and Wstands for Write Only.
