Cutting edge technologyfor connectivity
BMS connectivity The CAREL controllers can be connected to the BMS in the following ways:
- directly, thanks to the ability of the pCO sistema series controllers to select the protocol used (CAREL, Modbus®);
- using a gateway that converts the CAREL proprietary protocol to the protocol used by the BMS (BACnet™, SNMP, LON…);
- integrating the driver for the management of the CAREL proprietary protocol into the BMS (OPC®, DLL CAREL).
The following popular protocols and systems are used by the CAREL controllers to ensure connectivity to the other systems:
This is the protocol designated in 1995 by ASHRAE (American
Society of Heating, Refrigerating and Air-conditioning
Engineers) as the organisation’s offi cial protocol.
Type of protocol supported:
• BACnet™ Ethernet™ ISO8802-2 over 8802-3*
• BACnet™/IP*
• BACnet™ MS/TP; communication
standard EIA-485*
The BACset tool (available for download from the
ksa.carel.com site) can be used to confi gure and test
pCOWeb and pCOnet board.
Management of the protocol used for the internet means
that the network infrastructure already existing in buildings
can be exploited, and standard software tools, such as
Internet Explorer, can be used for the remote management
of the installation. Immediate access to the data of the
installation from anywhere is now a reality.
SNMP SNMP (Simple Network Management Protocol) is a protocol
for the management of TCP/IP networks, established in
1988 on the specifi cations of the IAB (Internet Administration
Board), the body that supervises the internet protocol.
XMLXML fi les (eXtensible Markup Language) have now become
the international standard for the management of databases
and data exchange.
Create a database, alarm logs and graphs on the unit
variables is now easy using this new opportunity
offered by CAREL devices.
This is most widely used system used in the workplace for
exchanging information. CAREL controllers can now send
e-mails to instantly notify authorised personnel of any
malfunctions or service requirements.
LINUXThe embedded LINUX™ operating system allows the
addition of plug-ins developed by the user for their own
requirements.

With millions of devices installed all over the world, the
LonWorks® system, developed by Echelon®, is one of the
dominant solutions in the market of automation and
control in industry, offi ces, homes and transport.
Electrical standard supported: FTT10.
CAREL is a LonMark® Partner.
The LONset tool (available for download
from the ksa.carel.
com site) can be used
to create the LON fi les
(NXE and XIF) for the
custom profi les.
Introduced in the’70s, this has now become one of
the most widely used protocols in BMS. The pCO
sistema series controllers are Modbus® enabled.
Type of protocol supported: Modbus® slave, RTU
mode; RS485 communication standard.
ModemDirect connection to a traditional or GSM modem, allowing:
• remote supervision by PlantVisor;
• remote connection via Winload.
The use of a GSM modem also offers the possibility
to communicate via SMS (short message service),
so as to:
• send alarms and information;
• receive commands to reset alarms;
• perform any actions without having to physically go to the installation.
OPC is an industrial standard created by a
consortium of companies, in collaboration with
Microsoft®, to standardise the drivers for proprietary
devices. Using the CAREL OPC server, any Windows® OPC client application
(SCADA, supervisors, management software, etc.) can communicate with
all CAREL devices in user-friendly OPC mode, without requiring a gateway.
TREND is a very widespread building automation system in
English-speaking countries and in Europe in general.
For further information on the supply and confi guration of the interface
board, contact trend@carel.com
CAREL provides a DLL that handles communication with
CAREL controllers.
Specifi cally, using the services provided by the routines
contained in the CAREL DLL, supervision software can be created to receive
and send data to and from all CAREL peripherals without needing to know
the protocol that these use.

FieldBus connectivityFrom the viewpoint of communication between controllers made by different companies, CAREL also offers a wide variety
of solutions for interfacing the pCO family controllers with fi eld devices such as valves, VFDs, serial sensors, Belimo
actuators etc. In this way, the pCO sistema series controllers not only manage the individual units, but the entire
air-conditioning/refrigeration installation.

CANbusThe CANbus option allows the pCO controllers to be
connected to the CAREL fan coil management system
(e-drofan), thus ensuring simpler management of the
installation and optimising, through synergy between the
controllers, comfort and running costs.
The MP-BUS® protocol can be used to manage up to 8
Belimo servo controls via a simple two-wire connection
cable.
ModemModels pCO3 and pCO1, using the FieldBus serial interface, and the optional RS232
board, can be connected to a PSTN or GSM modem, thus allowing control from a
remote position. In the same way as for the BMS version, in this case too the
controller can then send and receive SMS messages or manage a serial printer.
The tLAN option is used to connect pCO
controller to CAREL devices, such as I/O
expansions (pCOe) or electronic valve drivers
(EVD4). In addition, this option can be used to
connect pCO controller to the pLD display.

Modbus® Master or CAREL Master protocol.
The former is used to interface the pCO controller with a complete series of fi eld
devices that communicate via a serial connection using the Modbus® RTU
protocol. The CAREL Master protocol, on the other hand, ensures communication
with all CAREL devices, such as the µC, ir33 line products, etc.
