1. Description
1.1.Introduction
This document describes the integration of Panasonic VRF air conditioning systems into Modbus compatible devices
and systems using the Intesis Modbus Server to Panasonic VRF communication gateway.
The aim of this integration is to monitor and control Panasonic air conditioning systems, remotely, from a 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.
Intesis makes available the Panasonic air conditioning system indoor units’ datapoints through independent Modbus
registers.
Up to 128 indoor units supported, depending on product version.
This document assumes that the user is familiar with Modbus and Panasonic technologies and their technical terms.

2. Modbus interface
In this section, a common description for all Intesis Modbus series gateways is given, from the point of view of
Modbus system which is called from now on internal system. Connection with the Panasonic VRF system is also
called from now on external system.
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.
Configuration of poll records is possible between Modbus addresses 0 and 20000. Addresses that are not defined
in section 2.2 (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 (for 16 and 64
versions).
2.2.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.
2.3.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.

3. Connections
3.1.Connections for 16 and 64 versions (INMBSPAN016O000 and INMBSPAN064O000)
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 of 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/IP / Console (UDP & TCP)
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.
PortA / P-Link Panasonic
Connect the P-Link terminals of Panasonic Outdoor Unit to the
connectors A3 and A4 of gateway’s PortA. There is no polarity to
be respected.
PortB / Modbus-RTU RS485
Connect the EIA485 bus to connectors B1 (B+), B2 (A-) and B3 (SNGD) of gateway’s PortB. Respect the polarity.
Note for PortB: 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.
Bus biasing and termination resistor for EIA485 can be enabled for PortB by means of a dedicated DIP:
SW1: ON: 120 Ω termination active
OFF: 120 Ω termination inactive.
SW2+3:
ON: Polarization active
OFF: Polarization inactive.
If the gateway is installed in one bus end, make sure that termination is active.
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 HDD) if required. Check the user manual for more information.
Ensure proper space for all connectors when mounted (see 6DIMENSIONS).

3.2.Connections for 128 version (INMBSPAN128O000)
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 of 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/IP / Console (UDP & TCP)
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). With factory settings, after
powering up the gateway, DHCP will be enabled for 30
seconds. After that time, if no IP is provided by a DHCP server,
the default IP 192.168.100.246 will be set.
PortA / P-Link 1 Panasonic
Connect the P-Link terminals of Panasonic Outdoor Unit to the connectors A3 and A4 of gateway’s PortA. There is
no polarity to be respected.
PortB / P-Link 2 Panasonic
Connect the P-Link terminals of Panasonic Outdoor Unit to the connectors B1 and B2 of gateway’s PortA. There is
no polarity to be respected.
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.

3.3.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 5ELECTRICAL &MECHANICAL FEATURES). Once connected the ON led will turn on.
WARNING! To avoid earth loops that can damage the gateway, 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.
3.4.Connect to Panasonic VRF installation
Use the PortA connector in the top corner of the Intesis device to connect P-Link bus to the Intesis. Remember to
follow all safety precautions indicated by Panasonic.
Connect the Panasonic P-Link bus to connectors A3 and A4 of gateway’s PortA. Bus is not sensitive to polarity.
For the product version supporting 128 units (INMBSPAN128O000), connect the Panasonic P-Link 2 bus to
connectors B1 and B2 of gateway PortB. Bus is not sensitive to polarity.
3.5.Connection to Modbus
3.5.1. Modbus TCP
The gateways Ethernet port connection is used for Modbus TCP communication. 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.
TCP port to use (default 502) and keep alive period must be configured.
IP settings of the gateway (DHCP status, own IP, netmask and default gateway) must be configured as well.
3.5.2. Modbus RTU (only for INMBSPAN016O000 and INMBSPAN064O000)
Connect the communication cable coming from the motbus network to the port marked as Port B of the 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.
3.6.Connection to Modbus TCP/IP (Energy meters)
Use the Ethernet connector to communicate with the Modbus Energy meters.
Once the Energy meters are connected, running and tested, make sure they are available from the Intesis device
LAN network/IP before going to the next step.
3.7.Connection to PC (Configuration tool)
This action allows the user to have access to configuration and monitoring of the device (more information can be
found in the configuration tool User Manual). Two methods to connect to the PC can be used:
•Ethernet: Using the Ethernet port of Intesis.
•USB: Using the console port of Intesis, connect a USB cable from the console port to the PC.

3.5 Ambient temperature provided from Modbus. This option enables a Modbus register to receive an
ambient temperature from Modbus to regulate the AC unit using Virtual Temperature function.
Case 1: Temperature setpoint IS NOT provided from Modbus. (Checkbox deactivated).
In this case, the user setpoint is directly applied to the AC unit. Setpoint control and ambient temperature is
based on the following registers:
([IU] * 100) +
(([L] - 1) * 10000) + 4
R/W
Temperature Setpoint (x10ºC)
16…30°C
([IU] * 100) +
(([L]- 1) * 10000) + 5
R
Ambient Temperature (x10ºC)
-35…92,5ºC
-31…198,5ºF
•Register 4: Temperature Setpoint (x10)
This register can write the desired user setpoint and will be updated with the current setpoint in the AC unit
at any time.
•Register 5: Ambient temperature (x10)
This register can be read only and will inform about the ambient temperature measured by the AC unit
temperature probe, which usually corresponds with the temperature measured in the return path. See AC
settings for further information.
Case 2: Temperature setpoint IS provided from Modbus (use Virtual temperature) (Checkbox
activated)
This feaure is provided to be used only in the following cases:
•There is no setpoint control from BMS or centralized system in parallel to the Intesis device.
•There is no setpoint control from RC, infrared remote or any other AC optional which allow
setpoint management.
Considerning these sentences, the resulting system is that in which the setpoint control is only performed
through the Intesis gateway.
Enabling this feature will add two additional Modbus temperature registers to the previous list:

•Register 4: Temperature Setpoint (x10)
This register can write the desired user setpoint but now this register will not be updated with the current
setpoint in the AC unit. This way, reading this register in the Case 2 will report the last setpoint temperature
set in this Modbus register.
•Register 5: Ambient temperature (x10)
This register has the same meaning than Case 1.
•Register 28: Modbus ambient temperature (x10)
This register can receive a temperature value coming from Modbus. This value is used to calculate a real
setpoint for the AC unit using the below expression.
•Register 29: AC Real Temperature setpoint (x10)
This register will report the real AC setpoint temperature at any time. This is the value calculated in the
below expression.
In Case 2, user setpoint temperature (register 4) is not directly applied to the indoor unit but modified using
the Virtual Temperature formula. This way, the real setpoint applied to the AC unit follows the next
expression:
𝑹𝒆𝒂𝒍 𝑨𝑪 𝑺𝒆𝒕𝒑 = 𝑨𝑪 𝑨𝒎𝒃 𝑻𝒆𝒎𝒑 − (𝑴𝒐𝒅𝒃𝒖𝒔 𝑨𝒎𝒃 𝑻𝒆𝒎𝒑 − 𝑴𝒐𝒅𝒃𝒖𝒔 𝑺𝒆𝒕𝒑 𝑻𝒆𝒎𝒑), where:
•Real AC Setp (AC Real Temperature Setpoint) is register 29.
•AC Amb Temp (Ambient Temperature) is register 5.
•Modbus Amb Temp (Modbus ambient temperature) is register 28.
•Modbus Setp Temp (Temperature Setpoint) is register 4.
Basically, Virtual Temperature function modifies the setpoint temperature set from Modbus in register 4
making possible to use a Modbus temperature probe as a reference (register 28) for the AC control loop.
The idea of the Virtual Temperature is to keep the room temperature difference (in Modbus) and apply it to
the AC control loop by modifying the setpoint.
This value is recalculated constantly adapting the temperature difference to the AC control loop so the lower
temperature delta in Modbus result in a lower temperature delta applied to the AC unit and the opposite (the
higher…the higher).
Example: in a certain installation, we have the following data:
➢Ambient temperature measured in a Modbus temperature probe = 23ºC (register 28).
➢User demands, from a Modbus thermostat, a setpoint = 25ºC (register 4).
➢The AC unit is measuring in the return path a temperature = 24ºC (register 5).
Following this example and considering the sytem working in heating mode, the real AC temperature setpoint
(register 29) applied to the AC is:
Real AC Setp (ºC) = 24 –(23 –25) = 24 –(–2) = 24 + 2 = 26 ºC

4.2.5. Panasonic configuration
Set parameters for connection with Panasonic’s installation.
Figure 4.4 Intesis MAPS Panasonic configuration tab
Line configuration section
Each line of Panasonic needs to be addressed by using the parameter “Gateway Address in Panasonic line”.
There are 2 addresses reserved for the gateway in the Panasonic bus: address 1 and address 2.
Note that only the version of 128 units allows the connection to 2 Panasonic lines simultaneously. The 16- and 64-
unit versions will only support the configuration of the “Panasoni Line 1”.
In Units Configuration section you need to enter, for each unit:
•Unit ID. If it’s active (checkbox at Unit xx), ranging from 1 to 64 indoor units that will be integrated (maximum
number of units will depend on Intesis model)
•OU address. Address 1…64 of Outdoor Unit in Panasonic P-Link bus.
•IU address. Address 1…64 of Unit in Panasonic P-Link bus.
•Unit type. Type will default to ‘Not Defined’. When units have been detected after scan, it can be one of the
following: TBD, GHP, PAC and VRF
•Description. Descriptive name to easy identification of the unit (for example, ‘living room floor 1 unit’, etc).
Additional to manual entry of each unit, autodiscover of present units in a P-Link installation is possible. To do so,
click button Scan. Following window will appear:

Figure 4.5 Intesis MAPS Scan Panasonic Units window
Scan parameters:
There are 2 different types of Scan to be applied. By default, the fastest one is defined since it is assumed that
Panasonic units (indoor units and outdoor units) have been addressed. However, and only in case the units do not
have an address assigned, the parameter “Installation with units not addressed (no central address assigned)”
must be selected.
Please take into consideration that when the installation is not addressed, the scan process might take longer than
the standard scan (up to 60 min). To decrease this time, it is highly recommended to reduce the OU range to be
scanned as much as possible:
