Gateway for integration of Mitsubishi Heavy Industries air conditioning systems into Modbus (RTU and TCP) systems.

**Description

**

1.1 Introduction
Intesis™ 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 to 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.
1.2 Integration signals
***** Following is the list of parameters that can be monitored/controlled on the indoor units using Intesis™:

• For each indoor unit in the system:
• Communication Status (read-only)
• On/Off (R/W)
• Operation Mode (R/W)
• SetPoint Temperature (R/W)
• Fan Speed (R/W)
• Remote Controller Lock/Unlock (R/W)
• Louver Control (R/W)

|

• Room Temperature (read-only)
• Filter Sign Status (read-only)
• Error Code (read-only)
• Compressor Status (read-only)
• Filter Sign Reset (write-only)
• Remote Controller Error Reset (write-only)
• Thermo On/Off Status (read-only)

---|---

***** Apart from these, the Intesis™also implements some extra signals (functions):

• For all indoor units1 in the system:
• HW Communication Status (read-only)
• On/Off (write-only)
• Operation Mode (write-only)
• SetPoint Temperature (write-only)
• Fan Speed (write-only)
• Remote Controller Lock/Unlock (write-only)

1 These signals work as master signals controlling all connected units at the same time

1.3 Functionality
Each of the mentioned signals in section 1.2 is associated with 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.

Figure 1.1 Integration of Mitsubishi Heavy Industries AC into Modbus system using Intesis™
Two Modbus mode connection types can be active in Intesis™: Modbus RTU or Modbus TCP, or both simultaneously.
Intesis™ 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 a communication error between the gateway and that precise device (see 0).
When a written order is done from Modbus is 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 Intesis™using the LinkBoxMB tool (see 4.2.2).
Intesis™ is capable of managing up to two simultaneous Modbus master connections.
Intesis™ includes all hardware needed to connect directly with the Mitsubishi Heavy Industries indoor units connecting with the Superlink network.

• Mitsubishi Heavy Industries interface configuration parameters:
1 In the LinkboxMB this connection is labeled as RS232 and RS485 respectively.

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 a 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.
Content in this tab is just informative: no information has to be set up.

Figure 4.5 Modbus signal list

1. Address Formula: Formula used by Intesis™ 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.
4.3 Sending the configuration to Intesis™
When the configuration is finished, follow the next steps.

1. – Click on the 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 Intesis™starts to work as expected.

3. – Once in the configuration window again, click on exit. The configuration file is ready to be sent to the Intesis™ 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 the button Send File.

4.4 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 value1 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 Intesis™, 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.

1 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 Signal value change window

4.5 Files
LinkBoxMB saves the integration configuration in the following files inside the project folder:

through the “Connection” tab in IntesisTM configuration
MHI.XBOX| A binary file was 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.

The setup process and troubleshooting

5.1 Pre-requisites
