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

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)

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.

Table 1.1 IntesisTM capacity

* There are two different models of IntesisTM 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:

▪INMBSMHI048O000:

▪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

▪INMBSMHI128O000:

▪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 IntesisTM

Description

IntesisTM 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 supported

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 RTU

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 TCP

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 IntesisTM can be also

configured.

Address Map

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.
