IntesisTM Modbus Server Mitsubishi Heavy Industries AC

User's Manual r1.0 eng

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: o Communication Status (read-only) o On/Off (R/W) o Operation Mode (R/W) o SetPoint Temperature (R/W) o Fan Speed (R/W) o Remote Controller Lock/Unlock (R/W) o Louver Control (R/W) o Room Temperature (read-only) o Filter Sign Status (read-only) o Error Code (read-only) o Compressor Status (read-only) o Filter Sign Reset (write-only) o Remote Controller Error Reset (write-only) o Thermo On/Off Status (read-only)
Apart from these, the IntesisTM also implements some extra signals (functions):
For all indoor units1 in the system: o HW Communication Status (read-only) o On/Off (write-only) o Operation Mode (write-only) o SetPoint Temperature (write-only) o Fan Speed (write-only) o Remote Controller Lock/Unlock (write-only)

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

Figure 1.1 Integration of Mitsubishi Heavy Industries AC into Modbus system using IntesisTM
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.

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 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 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.

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.

Files

Figure 4.7 Signal value change window

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

PROJECT.INI MHI.INI MHI.LBOX

INI file containing general information related to the project
INI file containing information related with the values configured through the "Connection" tab in IntesisTM configuration 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.
