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, AG-150A or AE200A gateway. This gateway from

Mitsubishi Electric offers the signals of the City Multi AC system through XML protocol. Every

G50 (G-50A, GB-50A, AG-150A, AE200A) 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 and AE200A 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

AG-150A and AE200A. In this document we will refer to this three gateway models (G-

50A, GB-50A, AG-150A and AE200A, without Expansion Controllers) as just G50.

An AG-150 with 2 EC or an AE200 with one 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. !

For more information consult Mitsubishi Electric technical documentation supplied with the

G50.

1.3 Functionality

Every one of the mentioned signals is associated to a predefined fixed Modbus address, with

this, all the system is seen as a single Modbus slave unit with a fixed Modbus address map.

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: 1..2

GROUP NUMBER: 1..50

SIGNAL NUMBER: 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.

3.2 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




URL Email tel


13 / 33

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.




URL Email tel


14 / 33

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.

3.4 Signals list

Select the Points tab to see the signals list.

In this case (integration of Mitsubishi Electric G50), there is no need of configuring the

signals list because the IntesisBox has a fixed Modbus address map for the signals of the

G50s configured. The signals list in this particular integration is just to consult and for user

informative purposes.

Signals list

1. Address Formula. Formula used by IntesisBox to define the Modbus address for the

point. Use this address (obtained with this formula) to access the point from your

Modbus master device. See section 2.4 Address Map.

2. Property. Property number of the G50 signal. See section 2.4 Address Map.

3. R/W. Indicates if the signal is Read only, Write only, or Read and Write (always from the

Modbus system point of view). See section 2.4 Address Map.

4. Signal. Signal description. See section 2.4 Address Map.

5. Values. Possible values for the signal. See section 2.4 Address Map. When connecting to

PWFY units the values differ from the standard ones. In this column both of them are

specified

3.5 Sending the configuration to IntesisBox

When the configuration has been saved (button Accept) and the IntesisBox configuration

binary file has been generated (remember to select yes when asked if you want to generate

the IntesisBox file), to send the configuration file to IntesisBox click on the button Send

File. The process of file transmission can be monitored in the IntesisBox Communication

Console window. If the file transmission is ok, IntesisBox will reboot automatically with the

new configuration loaded.

Remember that saving the configuration and generating the IntesisBox file only saves to the

hard disk on the PC the configuration files. Do not forget to send the configuration file

to the IntesisBox using button Send File.

21 / 33

3.6 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).

3.7 System commands

LinkBoxMB includes an option to send to IntesisBox a set of system commands for

debugging and control purposes; this list is available in the commands list as shown in the

figure below. To send a command to IntesisBox just select it from the list, or type it with

the correct format, and press Enter or click on button Send. IntesisBox will act accordingly

with the command received; the process can be monitored in the IntesisBox Communication

Console window. The use of some of these commands can be critical for IntesisBox normal

functioning, having this in mind use only these commands following the recommendations

of Intesis Software technical support. A list of the more commonly used commands and the

way to use them will be returned by IntesisBox after sending the command HELP.

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

PROJECT.INI

.ini file containing general information referent to the project

MITSUBISHIG50.INI .ini file containing the information referent to the connection

window and other special adjustments

MITSUBISHIG50.DAT

Text file (tab separated values) with the contents of the signals list.

MITSUBISHIG50.LBOX Binary file created from the information in the files described

above. This is the file downloaded to the IntesisBox.

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 IntesisBox to LinkBoxMB, only can be

downloaded; the download file MITSUBISHIG50.LBOX does not contain all the

integration information, as for example the signals description.

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.

6. Connect the communication cable coming from the serial port of your laptop PC to the

port marked as PC Console of IntesisBox. (See details for this communication cable in

section Connections of this document).

7. Open LinkBoxMB, create a new project selecting a copy of the one named DEMO

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).

10. Open the External Protocol Communication Viewer window (menu View -> Bus ->

MitsubishiG50) and check that there is communication activity, some TX frames and

some other rx frames as showed in the figure below. This means that the

communication with the Mitsubishi Electric system is ok.

In case there is no response from the Mitsubishi Electric G50 devices to the frames sent

by IntesisBox, check that they are operative and reachable from the network connection

used by IntesisBox, check the IntesisBox's Ethernet interface making pings to its IP

address using a PC connected to the same Ethernet network. See details for the

communication cable between IntesisBox and Mitsubishi Electric in section Connections

of this document.
