IntesisBox® Modbus Server - Mitsubishi Electric G50
User’s manual r18 eng
1. Description
1.1
Introduction
IntesisBox® Modbus Server - Mitsubishi Electric G50 is a communication gateway for
Mitsubishi Electric City Multi air conditioning systems to Modbus slave (RTU and TCP).
This gateway allows integrating the Mitsubishi Electric City Multi AC inside a
supervision/control/automation system through PLC, SCADA, and in general through any
device or system with Modbus mastering (TCP or RTU) interface.
This integration requires the Mitsubishi Electric City Multi AC system be equipped with the
Mitsubishi Electric G-50A, GB-50A or AG-150A gateway. This gateway from Mitsubishi
Electric offers the signals of the City Multi AC system through XML protocol. Every G50 (G50A, GB-50A, or AG-150A) allows access to the signals of up to 50 City Multi indoor units
and 50 groups, no matter the number of outdoor units installed. In the G50, the group is
the control unit, every group can have from 1 to 16 associated indoor units. This integration
supervise and control groups, not indoor units, although if only one indoor unit is associated
to every group then you can supervise and control indoor units individually.
This G50 gateway is supplied by Mitsubishi Electric. The difference between the G-50A and
GB-50A is that the first incorporates display and keyboard and the second one just blind
cover. The new AG-150A is also compatible with IntesisBox (with or without Expansion
Controllers). At integration level, all of them allow the same functionality. Contact your
nearest Mitsubishi Electric distributor for more details about G-50A, GB-50A and AG-150A.
In this document we will refer to this three gateway models (G-50A, GB-50A and
AG-150A, without Expansion Controllers) as just G50. An AG-150 with 2 EC would
work as 2 G50.
!
NOTE: Please, remember that Mitsubishi Electric AG-150A requires a
software license, PC-Monitoring license (SW-Mon), that has to be
purchased together with the AG-150A gateway.

Only needed for configuration
It can only be one Modbus Mode active simultaneously in IntesisBox ®, Modbus RTU or
Modbus TCP.
IntesisBox® continuously polls (read) all the signals configured of the G50's and maintains
the updated values to be served in Modbus.
When a write is done from Modbus in a gateway's Modbus address (allowed to be written),
the corresponding order is sent to the City Multi signal associated.
In the continuous polling process of the G50, if there is no answer, it is indicated with a
virtual signal of communication error. The same way, there is a communication error virtual
signal per every City Multi group, which normally will be activated if this group is not
configured in the G50. Note that, although the City Multi indoor units are not physically
connected, the G50 responds as if they were.
The IP address and TCP port (will be always 80) of every G50 to connect to can be also
configured.
The signal's polling cadence (read) can also be configured.
IntesisBox® automatically detects the groups configured in every G50. Those groups not
found during the first poll are deactivated automatically in the polling process. This
behaviour can be disabled in IntesisBox®.

2. Modbus interface of IntesisBox
2.1
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 functions 06 and 16 (Single Multiple Holding Registers and Write Multiple Holding
Registers) can be used to write Modbus registers.
If poll records are used to read or write more than one register, it is necessary that the
range of addresses requested contains valid addresses, if not the corresponding Modbus
error code will be returned.
All the registers are of 2 bytes (although its possible values can only be 0..1) and its
content is expressed in MSB..LSB.
Modbus error codes are fully supported, they will be sent whenever a non valid Modbus
action or address is required.
2.2
Modbus RTU
Baud rate can be selected from 1200, 2400, 4800, 9600, 19200, 38400 and 56700 (Data
Bits: 8, parity: none, Stop Bits: 1).
Modbus slave number can be configured. Physical connection (RS232 or RS485) can also be
selected.
Only the lines RX, TX and GND of the RS232 connector are used (TX and RX for RS485).
2.3
Modbus TCP
The TCP port to use can be configured (by default 502 is used).
The IP address, subnet mask and default router address to use by IntesisBox ® can be also
configured.
2.4
Address Map
The are 18 signals per every City Multi group plus one more signal per every G50. The
address map is based in a base address for every one of these signals. The Modbus address
for every point is obtained adding an offset (according to the number of groups and number
of G50s) to this base address.
ModBus Address = ( ( (G50 NUMBER – 1) X 50 ) + GROUP NUMBER ) X 100 + SIGNAL NUMBER
Where:
G50 NUMBER:
GROUP NUMBER:
SIGNAL NUMBER:
1..2
1..50
1..18
For the G50's communication error addresses, the following formula is applied:
Modbus Address = G50 NUMBER

3. LinkBoxMB. Configuration & monitoring tool for IntesisBox
Modbus Server series
3.1
Introduction
LinkBoxMB is a Windows 98/NT/2000/XP compatible software developed specifically to
monitor and configure IntesisBox Modbus Server series. It is possible to configure all
external protocols available for IntesisBox Modbus Server and to maintain different
customer’s configurations based on a LinkBoxMB project for every different installation.
Maintaining always on hard disk a copy of the last configuration files for every external
protocol and customer, that is to say for every project.
From LinkBoxMB, as well as configure the integration signals list and connection parameters
for every external protocol, it is permitted to select the serial port to use to connect to
IntesisBox Modbus Server and the use of some tools for monitoring and debugging de
device. Some of these tools will be explained in this document but only some of them, the
rest of available debugging tools and commands will not be explained here because they are
for exclusive use under the recommendations of Intesis Software technical support.
LinkBoxMB allows configuring all IntesisBox Modbus Server series independently of the
external system used. For every external system, LinkBoxMB has a specific configuration
window. Periodically, new free versions of LinkBoxMB are released incorporating the latest
developed integrations for external systems.

Project definition
The first step to do in LinkBoxMB for a new installation is to create the installation’s project
giving a descriptive name to it. When you create a project, a new folder is created with the
name of the project containing the configuration files needed depending on the external
protocol selected for the project. It is strongly recommended that you create a new project
for every installation, if not, overwriting of configuration files of previous installations using
the same external protocol may occur, loosing the configuration data for those previous
installations. The projects folder is located in AppFolder\ProjectsMB, where AppFolder is the
installation folder of LinkBoxMB (by default C:\Program Files\Intesis\LinkBoxMB). Inside the
projects folder, a new folder will be created for every project defined in LinkBoxMB with the
files needed for the project.
When you open LinkBoxMB, the project selection window will appear inviting you to select a
project or create a new one. A demo project for every external protocol supported is
provided with the standard installation of LinkBoxMB. You can create a new project or select
a demo project based on the external protocol desired, and create a new one from the
demo one selected.
Project selection window
To create a new project, select a project using the same external protocol you want to use
in the new project and click on New button. You will be prompted to create a copy of the
selected project (useful for similar installations) or create a new one.
If you select Yes you will be prompted to specify a name and a description for the new
project that will be based on the same external protocol than the selected one. If you select

No you can specify a name, a description and an external protocol to use from the list of
available external protocols.
On Accept, a new folder will be created inside the projects folder with the name given to the
project, this folder will contain the template configuration files if the project is a brand new
one, or a copy of the configuration files if it is a copy of a selected one.
A description of the files created for a Mitsubishi Electric G50 protocol based project can be
found in section Files in this document.
From all the possibilities of LinkBoxMB, only changes in configuration for the integration and
configuration file generation can be performed while disconnected from IntesisBox (working
off-line), allowing you to do these tasks in the office more comfortably. Before any
monitoring or downloading action to IntesisBox can be performed, the connection between
IntesisBox and the PC running LinkBoxMB must be established (working on-line). To do so
follow these steps:
1. Make sure IntesisBox is powered-up a correctly connected to the Modbus system via the
Ethernet connection (Modbus TCP) or serial connection (Modbus RTU) and to Mitsubishi
Electric G50 devices via the Ethernet network (consult details for connection and pin
assignments in section Connections of this document).
2. Connect a free PC serial port to the IntesisBox serial port marked as PC Console. (Use
the standard serial cable supplied with the device or a customer’s cable following the pin
assignments specified in section Connections in this document).
3. Select in LinkBoxMB the PC serial port used for the connection to IntesisBox. Use menu
Configuration -> Connection.

4. Check the checkbox off-line under the menu bar (it will change automatically to on-line)
and LinkBoxMB will ask for INFO about the IntesisBox connected to it via the serial
connection, if the connection is ok then IntesisBox will respond with its identification
(this can be monitored in the IntesisBox Communication Console window, as showed
below).
Once connected to IntesisBox, all the options of LinkBoxMB are fully operative.
To monitor the communication between IntesisBox and the Modbus master device, select
the menu View -> Bus -> Modbus. The Modbus communication Viewer window will be
opened. This window show in real time all the communication frames between IntesisBox
and the Modbus master device as well as debugging messages referent to internal protocol
(Modbus) sent by IntesisBox.
To monitor the communication between IntesisBox and the external system (Mitsubishi
Electric G50 in this case), select the menu View -> Bus -> MitsubishiG50. The External
protocol communication viewer window will be opened. This window show in real time all
the communication frames between IntesisBox and G50 devices as well as debugging
messages referent to external protocol (Mitsubishi Electric G50) sent by IntesisBox.

Signals viewer
Once IntesisBox is running with the correct configuration, to supervise the status of the
configured signals, select menu View -> Signals. The Signals Viewer window will be opened.
This window shows all the active IntesisBox's signals with its main configuration parameters
and its real time value in the column Value. After a reset of IntesisBox or after sending a
configuration file to the IntesisBox, all the signal's values will be updated automatically in
the signals viewer, in case you connect to the IntesisBox when it is already running, you
should press the Update button to get updated values, press just once the button to update
all the signals values, since that moment the signal values will be maintained updated until
the connection is closed.
The signals viewer can be used although only one system is connected to the IntesisBox,
Modbus or Mitsubishi Electric G50, and is very useful for supervision and test.
It is possible to force a specific value to any signal for test purposes, to do so just double
click on the row and select the desired value and Accept in the Data Test window. If the
signal is of type R or RW, then the value entered will be available to be read from Modbus
master device, if the signal is of type W or RW, then the value entered will be sent to the
corresponding Mitsubishi Electric G50.
This tool is very useful to test any of the systems connected to IntesisBox, Modbus and
Mitsubishi Electric G50 without the need to actuate on the real signals.
The signals viewer window has a button to copy to the Windows Clipboard all the contents
of the window (in tab separated text format).

4. Setup process and troubleshooting
4.1
Pre-requisites
It is necessary to have the Modbus master device operative and well connected to the
Modbus port of IntesisBox, remember to respect the maximum of 15 meters cable distance
if using RS232 communication.
It is necessary to have an Ethernet 10BT network connection near IntesisBox (network hub
or switch port) with all Mitsubishi Electric G50 devices connected to this Ethernet network.
Connectors, connection cables, PC for LinkBoxMB, and other auxiliary material, if needed,
are not supplied by Intesis Software for this standard integration. The items supplied by
Intesis Software for this integration are:

IntesisBox Modbus Server device with Mitsubishi Electric G50 external protocol
firmware loaded.
LinkBoxMB software to configure IntesisBox.
Console cable needed to download the configuration to IntesisBox.
Product documentation.



If requested, Intesis Software also can supply:
 Standard plug-in power supply 220Vac 50Hz to power IntesisBox (European plug
type).
4.2
Setup procedure
1. Install LinkBoxMB on your laptop, use the setup program supplied for this and follow the
instructions given by the Installation wizard.
2. Install IntesisBox in the desired installation site. The mounting can be on DIN rail or on
a stable not vibrating surface (DIN rail mounted inside a metallic industrial cabinet
connected to ground is recommended).
3. Connect the communication cable coming from the Modbus master device to the port
marked as Modbus of IntesisBox (used either RS232, RS485 or Ethernet port
depending on the type of Modbus communication to use). (See details for this
communication cable in section Connections of this document).
4. Connect the communication cable coming from the network hub or switch to the port
marked as ETH of IntesisBox. (See details for this communication cable in section
Connections of this document).
5. Power up IntesisBox. The supply voltage can be 9 to 30 Vdc or just 24 Vac. You can use
also the standard plug-in power supply 220/125VAC-12VDC/300mA supplied with the
device (if requested). Take care of the polarity of the supply voltage applied.
WARNING! In order to avoid earth loops that can damage IntesisBox and/or any
other equipment connected to it, we strongly recommend:


The use of DC power supplies, floating or with the negative terminal connected to
earth. Never use a DC power supply with the positive terminal connected
to earth.
The use of AC power supplies only if they are floating and not powering any other
device.

MitsuG50 and give it the name desired, select the serial port used to connect to
IntesisBox (menu Configuration -> Connection) and switch working mode to on-line
(checkbox off-line/on-line). The IntesisBox identification must appear in the IntesisBox
communication console window as showed below.
8. Modify the configuration as desired, save it and download the configuration file to
IntesisBox as explained before.
9. Open the Modbus Communication Viewer window (menu View -> Bus -> Modbus) and
check that there is communication activity, some TX frames and some other rx frames.
This means that the communication with the Modbus master device is ok. In case there
is no communication activity between IntesisBox and the Modbus master device check
that it is operative, check the baud rate, and check also the communication cable used
to connect both devices. (See details for this communication cable in section
Connections of this document).
