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.

2.1.2 City Multi Group signals
The are up to 38 signals per every City Multi group. The number of actual addresses will depend on unit type,
configuration and features of the centralized controller. Their Modbus addresses can be obtained applying the
following formula:
Modbus Address = (( CC NUMBER X 50 ) + GROUP NUMBER ) x 100 + SIGNAL NUMBER
Where:
CC NUMBER: 0..1
GROUP NUMBER 1..50, according to configuration in Centralized Controller
SIGNAL NUMBER: 0..37, see following table
Modbus address from the formula is expressed in link layer format. This is, first register address is 0.
Available signals depend on unit type, which must be selected in MAPS configuration tool:
•IC: Air conditioning indoor unit (VRF, M-series, P-series and K-control unit)
•LC: Lossnay
•FU: Outdoor-Air Processing unit
•BU: Air to Water Booster unit
•WH: Air to Water HEX unit
•CEh: Heat Pump
