1 Description
Introduction
This document describes the integration of Mitsubishi Electric’s City Multi series air conditioning systems into Modbus
compatible devices and systems using the Intesis Modbus Server to Mitsubishi Electric’s Centralized Controller
communication gateway.
The aim of this integration is to monitor and control Mitsubishi Electric City Multi air conditioning system, remotely,
from your Control Center using any commercial SCADA or monitoring software that includes a Modbus Master driver
(RTU and/or TCP). To do it so, Intesis performs as a Modbus Server, allowing poll and write requests from any
Modbus master device.
This integration requires the Mitsubishi Electric City Multi AC system to be equipped with a Mitsubishi Electric’s
Centralized Controller for MNET (G-50A, GB-50A, AG-150A, EB-50, EW-50 or AE200 and newer). This Centralized
Controller offers the signals of the City Multi AC system through XML protocol at its Ethernet port, which is accessed
by the Intesis. Every Centralized Controller from Mitsubishi Electric allows access to the signals of up to 50 City Multi
indoor units groups, no matter the number of outdoor units installed. In the Centralized Controller, the control unit is
the group, each of which can have from 1 to 16 associated indoor units.
MNET’s Centralized Controller is offered by Mitsubishi Electric. Each different model has different features (some
incorporate just a blind cover, others have a keyboard and an LCD panel). Mitsubishi Electric’s Expansion Controllers
can be connected to the MNET Centralized Controller in order to extend to more than 50 indoor unit groups (50
additional groups for each Expansion Controller). Expansion Controllers in MNET system is also supported by Intesis.
Intesis needs to be configured using Intesis MAPS software configuration tool. In the software, Modbus and MNET’s
Centralized Controller parameters must be configured and downloaded to the Intesis.
Up to 50 indoor unit groups (1 Centralized Controller) or 100 indoor unit groups (2 Centralized Controllers) are
supported, depending on the version of the gateway.
This document assumes the user is familiar with Modbus and Mitsubishi Electric technologies and technical terms.

NOTE: Please take into acount that most Mitsubishi Electric Centralized Controllers

together with the controller in order that the XML interface is active and can be used by
the Intesis.

Functionality
IntesisTM continuously polls (reads) all the signals of the Centralized Controller groups and maintains the updated
values to be served in Modbus.
When a write is done from Modbus in a gateway's Modbus writeable address, the corresponding command is sent
to the City Multi associated signal.
In the continuous polling process of the Centrallized Controller, if there is no answer, it is indicated with a virtual
signal of communication error for the Centrallized Controller. In the same way, there is a communication error virtual
signal for each of the City Multi groups, which normally will be activated if this group is not configured in the
Centrallized Controller.
The IP address and communication parameters (polling cadence, connection timeout, …) of every Centrallized
Controller to connect to must be also configured using Intesis MAPS configuration tool, as well as Modbus TCP or
RTU communication parameters.
From the configuration tool, it is also possible to scan the Centrallized Controller for available groups and thereafter
add them in the configuration, so that they are continuously polled.

2 Modbus interface
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.
Configuration of poll records is possible between Modbus addresses 0 and 20000. Addresses that are not defined in
section 2.4 (Modbus map of the device) are read-only and will always report 0.
Modbus error codes are supported, they will be sent whenever a non-valid Modbus address is queried.
All registers are 16-bit signed integer, in standard Modbus Big Endian (MSB/LSB) format.
Intesis supports Modbus RTU and Modbus TCP and both interfaces can be used simultaneously.
Modbus RTU
Both EIA485 and EIA232 physical layers are supported. Only the lines RX, TX and GND of the EIA232 connector
are used (TX and RX for EIA485).
Baud rate can be selected between 1200, 2400, 4800, 9600, 19200, 38400, 56700 and 115200. Parity (none, even
or odd) and stop bits (1 or 2) can be selected as well.
Modbus slave number must be configured and the physical connection (RS232 or RS485) can also be selected.
Modbus TCP
TCP port to use (default is 502) and keep alive period must be configured.
IP settings of Intesis (DHCP status, own IP, net mask and default gateway) must be configured as well.
Modbus Address Map
2.1.1 Centralized Controller signals
There are 26 global signals for each centralized controller. Their Modbus addresses can be obtained applying the
following formula:
Modbus Address = ( CC NUMBER X 30 ) + SIGNAL NUMBER
Where:
CC NUMBER: 0..1
SIGNAL NUMBER: 0..9, see following table
Modbus address from the formula is expressed in link layer format. This is, first register address is 0.

3 Connections
Find below information regarding the Intesis connections available.
Power Supply
Must use NEC Class 2 or Limited Power Source (LPS)
and SELV rated power supply.
If using DC power supply:
Respect polarity applied of terminals (+) and (-). Be
sure the voltage applied is within the range admitted
(check table below). The power supply can be
connected to earth but only through the negative
terminal, never through the positive terminal.
If using AC power supply:
Make sure the voltage applied is the value admitted
(24 Vac). Do not connect any of the terminals of the
AC power supply to earth, and make sure the same
power supply is not supplying any other device.
Ethernet / Modbus TCP / Mitsubishi C. Controller
Connect the cable coming from the IP network to the
connector ETH of the gateway. Use an Ethernet CAT5
cable. If communicating through the LAN of the building,
contact the network administrator and make sure traffic
on the port used is allowed through all the LAN path
(check the gateway user manual for more information).
Default IP is 192.168.100.246. DHCP is enabled by
default.
Figure 3.1 Gateway’s connections
PortA
Not used
PortB / Modbus RTU
Connect the EIA485 bus to connectors B1 (-), B2 (+) and B3 (SNGD) of gateway’s PortB. Respect the polarity.
Remember the characteristics of the standard EIA485 bus: maximum distance of 1200 meters, maximum 32 devices
connected to the bus, and in each end of the bus it must be a termination resistor of 120 Ω. The gateway has an
internal bus biasing circuit that incorporates the termination resistor. If you install the gateway in one of the ends of
the bus, then do not install an additional termination resistor in that end.
Console Port
Connect a mini-type B USB cable from your computer to the gateway to allow communication between the
Configuration Software and the gateway. Remember that Ethernet connection is also allowed. Check the user manual
for more information.
USB
Connect a USB storage device (not a HDD) if required. Check the user manual for more information.
Ensure proper space for all connectors when mounted (see section 66).

Power device
The first step to perform is to power up the device. To do so, a power supply working with any of the voltage range
allowed is needed (check section 5). Once connected the ON led will turn on.
Connect to Mitsubishi’s Centralized Controller(s).
Connect the communication cable coming from the network hub, switch or direct from the Centralized Controller to
the Ethernet port (Figure 3.1) of the gateway. The cable to be used shall be a straight Ethernet UTP/FTP CAT5 cable.
In case there is no response from Mitsubishi Centralized Controller to the frames sent by the gateway, check that it
is operative and reachable from the network connection used by the gateway. Check the gateway’s Ethernet interface
sending Pings to its IP address using a PC connected to the same Ethernet IP network. If the problem persists
communicating through the LAN of the building, contact the network administrator and make sure traffic on the port
used is allowed through all the LAN path.
Intesis Modbus Server –Mitsubishi Centralized Controller comes with DHCP functionality enabled by default.
Connection to Modbus
3.1.1 Modbus TCP
Same ethernet connection as for Mitsubishi’s Centralized Controller is used. Connect the communication cable
coming from the network hub or switch to the Ethernet port of Intesis. The cable to be used shall be a straight Ethernet
UTP/FTP CAT5 cable.
3.1.2 Modbus RTU
Connect the communication cable coming from the Modbus network to the port marked as Port B of Intesis. Connect
the EIA485 bus to connectors B1 (-), B2 (+) and B3 (SNGD) of gateway’s PortB. Respect the polarity.
Remember the characteristics of the standard EIA485 bus: maximum distance of 1200 meters, maximum 32 devices
(without repeaters) connected to the bus, and in each end of the bus it must be a termination resistor of 120 Ω. The
gateway has an internal bus biasing circuit that incorporates the termination resistor. Bus biasing and termination
resistor for EIA485 can be enabled for PortB by means of a dedicated DIP switch.
Connect to PC (Configuration tool)
This action allows the user to have access to configuration and monitoring of the device. Two methods to connect to
the PC can be used:
•Ethernet: Using the Ethernet port of the Intesis.
•USB cable: To connect the device to the PC, the USB cable supplied should be plugged to the USB Console
port.

Please note that the scan is taking the configiguration of “Unit Type”, “Num of Fan Speeds” and “URC Controller”
automatically so you might not need to modify these parameters after performing a scan.
Finally, in addition to Centralized Controller parameters, and parameters for each corresponding group, there is a set
of advanced global parameters defining the communication of the Intesis with the centralized controller. These are
following:
Figure 4.8 Advanced Parameters for communication with Centralized Controllers
For them, the default values should be correct for most installations. They might need adjusting in particular cases
where there are particular requirements in the communication. Their function is following:
1. Polling Period: Time in milliseconds between each request sent to the Centralized Controller
2. Answer Timeout: Time in seconds that Intesis will wait for a response from Centralized Controller after
sending a single request for information through TCP/IP.
3. Controller Connection Timeout: After Intesis starts TCP/IP socket connection, time that the Intesis will wait
for the Centralized Controller to accept the socket request. For each individual request, Intesis starts a new
socket connection.

4.1.5 Sending the configuration to Intesis
When the configuration is finished, follow the steps to program the gateway.
1.- Click on Save button to save the project to the project folder on your hard disk (more information in Intesis
MAPS User Manual).
2.- You will be prompted to generate the configuration file to be sent to the gateway.
a.- If Yes is selected, the file 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.- Press the Send File button to send the binary file to the Intesis device. The process of file transmission
can be monitored in the Intesis Communication Console window. Intesis will reboot automatically once the
new configuration is loaded.
