1. INTRODUCTION
c.pCO is a microprocessor-based, programmable electronic controller,
featuring a multitasking operating system, compatible with the c.pCO
Sistema family of devices, which includes programmable controllers, user
terminals, gateways, communication devices and remote management
devices. These devices represent a powerful control system that can be
easily interfaced with most Building Management Systems (BMS) available
on the market. The controller has been developed by CAREL to provide
solutions for several applications in air-conditioning, refrigeration and
HVAC/R in general. Its flexibility allows for creation of tailor made control
solutions according to customer specifications. Compared to pCO sistema,
the range is enhanced by a new compact controller, and consequently
comprises the c.pCOmini (4 DIN module and panel mounting version),
featuring 10 universal inputs/outputs and available with built-in driver for
single-pole electronic expansion valve, as well as the c.pCO Small, Medium,
Large, ExtraLarge models. The number of inputs/outputs can be increased
by connecting a c.pCOe expansion board.
Medium size controllers can feature also one or two built-in drivers for
electronic expansion valves. The Ultracap module (accessory) can be used
as an emergency power supply for valve drivers, so as to ensure total closure
of the valves in case of power failures (alternating current).
c.pCO can be connected in an Ethernet LAN to other c.pCO family
controllers. Each device in the LAN can exchange digital or analogue
variables with all the others, based on the application program used. c.pCO
can also be connected via a pLAN (pCO Local Area Network) to the pGD
range of terminals.
Each Fieldbus serial port, whether built into the controller or installed
via an optional card, can be connected to controlled field devices such as
valve and damper actuators and external drivers (e.g. drivers for electronic
expansion valves, EVD Evolution).
Each BMS serial port, whether built into the controller or installed via
an optional card, can be connected to field-level, automation-level
or management-level standard bus systems, such as Konnex®, LON®,
BACnet™, etc.
The real-time operating system (OS) manages priorities so as to ensure the
application program cycle time, 32-bit data and floating point numbers, and
the Ethernet multimaster and multi-protocol connection.
Main features:
• optimization of the memory occupied by the Operating System and
the application program, of the boot time, of the time for loading the
application program and of the cycle time;
• system response time optimization: the controller executes several
processes in parallel, each managed with a different priority;
• independent processes: each process, whether a protocol, USB port
management, data and alarm log (datalogger), data exchange with
tERA cloud service, works independently of the others;
• runtime debug (on target)
• native management of TCP/IP multitasking protocol
Local connectivity:
• built-in web server, completely customisable, supports HTML standard
and JavaScript. The 90 Mbyte memory can be used to store pages
created using the most common website development tools. Dynamic
methods (CGI, Common Gateway Interface) are available to read and
write the application program variables. Other innovative functions
include: the possibility to display the contents of the pGD1 terminal
in the browser, display graphs of data recorded by the datalogger and
plot data from probes and energy meters in real time (variable trends);
• file server (FTP): the c.pCO public file system can be accessed in the
local network via FTP. Consequently, an FTP client can be used to
connect to the controller so as to upload updates, web pages and
documents. The “.csv” (comma separated value) files exported by the
datalogger can be downloaded
• creation of accounts with different access privileges, associated to
both a webserver and an FTP server;
• management of multiple simultaneous instances of Modbus TCP/IP
Master and Slave protocol;
• management of BACnet™ protocol with B-BC profile (MSTP or TCP/IP,
license to be purchased separately).
Remote connectivity:
• integrated connectivity to the Carel tERA cloud service: by connecting a
normal router to the controller, a secure connection can be established to
the tERA server. Remote services can be activated for the management
of control variables, alarm notification, data analysis and reports. The
connections are encrypted using the SSL (Secure Socket Layer) standard, in
compliance with NIST, international reference for information security over
the internet.
• a firewall guarantees remote access only via a secure connection (tERA
cloud connection or encrypted VPN)
Integrated USB peripheral: it can be used to update the controller and
save web pages, documents and applications in the flash memory. Also
used to download the logs from the controller.
• c.pCO Small...Extralarge: the host and device USB ports are managed
directly by the operating system. USB host (top): a USB flash drive can
be used to load updates (operating system/application program) on
the controller. USB device port (bottom): by connecting c.pCO to a
personal computer, its memory is made available as a removable drive,
and at the same time a communication channel is established with the
c.suite software for programming and online debugging.
• c.pCOmini: the 2 USB ports are physically integrated into a single micro
USB port; the same performance is available as for the two ports on
the larger models.
Other features:
• the same controller can be connected to up to 3 pGD1/pGDE terminals
(semi-graphic terminals such as pGDs or touch screens such as pGDT
/ pGDx);
• external or built-in terminal with display and keypad with LED backlit
buttons, can be used for uploading software and commissioning;
• universal inputs/outputs configurable via an application program,
for connecting active and passive probes, digital inputs, analogue
and PWM outputs. This extends the possibilities of configuring
inputs/outputs without having to install a larger controller;
• possibility to use the c.suite software development environment,
installable on a personal computer, for creating and customising the
application program, simulating operation, supervising performance
and configuring the Ethernet network;
• wide range of models that differ in terms of:
• size (mini, Small, Medium, Large and Extralarge), to ensure maximum
flexibility according to the application;
• digital outputs (24/230 V relay) and SSR (solid state relay);
• NO or NC relay outputs
• integrated optically-isolated/not optically-isolated serial ports;
• optional built-in display;
• various types of connectors (spring, screw, etc.).
Software programming suite, c.suite: designed as a set of independent
modules, one for each phase in HVAC/R software development, c.suite
allows teams of professionals with different skills to work in a group on
the same project, increasing efficiency and adopting joint development
based on workflow. All the software modules cooperate with each other
based on centralised data exchange, optionally managed by a software
version number (SVN):
• c.strategy: environment where expert algorithm programmers prepare
the core of the application program. Features of the programming
environment:
- total independence of programming logic from the hardware and
the connected devices;
- availability of IEC 61131 standard languages: ST (structured text), FBD
(function block diagram), SFC (sequential function chart), LD (Ladder
diagram), which can also be used simultaneously;
- datatype management: 32-bit, floating point, array and native
structures;
- debug on target via USB port or Ethernet;
• c.mask: dedicated environment for developers of the user interface.
• c.design: definition of configurations, such as controller type and size,
type of inputs/outputs, master/slave protocols, default parameter values,
datalogger, network address and user management, connection to tERA
cloud services.
• c.factory: used to program the controller, loading the application program

3.2 Ethernet ports
The c.pCO Small...Extralarge controllers have two 10/100 Mbps/s
Ethernet ports. These two ports are connected internally via a switch
that automatically forwards any pass-through traffic not addressed to
the controller. In the case a failure is happening in an intermediate node
(i.e power supply interruption), then the network is disconnected. The
two ports feature auto crossover (Auto-MDIX). The c.pCOmini High End
controller features one 10/100Mbps/s Ethernet port.
3.3 Controller network connections
Multimaster or Master/Slave networks of c.pCO controllers can be created
using the Ethernet ports and the serial ports:
Connection via Ethernet port
The built-in Ethernet ports on the c.pCO can be used to create multimaster
and multiprotocol networks, with transmission speeds up to 100 Mbps.
The controllers can be connected together via an external switch (see the
figure below). For c.pCO Small...Extralarge models, the two Ethernet ports
are connected by an internal hub-switch, meaning a daisy-chain network
can be created without needing an external switch (see figure 3.c).

Connection via serial ports:
A master/slave network of c.pCO controllers can be created by using the
RS485 serial ports. Such networks comprise:
• one c.pCO controller (Master) that communicates via the Fieldbus
RS485 serial port using Carel Master or Modbus Master protocol;
• one or more c.pCO controllers (Slaves) connected to the point-to-point
network via the BMS RS485 serial port using Carel Slave or Modbus
Slave protocol.

Important warnings:
1. By applying appropriate impedance, a serial port with Master
hardware (FBus) supplies the network with the bias voltage required
to run all the connected devices, i.e. the master itself and its slaves;
conversely, serial ports with slave hardware (BMS) do not provide bias
voltage, so it is always advisable to connect at least one device with
master hardware (FBus) to the network so that it is correctly biased;
2. However, no more than two devices with master hardware (FBus)
can be connected to the same network, otherwise the network total
bias impedance becomes too small and incapable of supplying the
required voltage to the RS485 network.
3. It is recommended to connect the serial probes or other field devices
to an optically-isolated version of the Fieldbus serial port or to serial
port TWO – Fieldbus 1 to exploit the filtering properties of optical
isolation.
Special cases
• In networks consisting only of Master HW devices, no more than 2
devices can be connected. The max. length allowed for the network
is 1000 m. If the network is longer than 100 m, apply the 120Ω, 1/4W
terminating resistors to the first and last devices in the network;
• connect the computer to a network with no more than 1 master HW
device or no more than 207 slave HW devices.

Note:
• for correct assembly, follow the instructions shown in the following
diagram.
• Important: when assembling, make sure that the frame is securely in
place on all four sides.
• if needing to remove the frame, use a screwdriver to lever it off in slot C.
• to access the USB port, open the cover B and lift the rubber cap A
using the tab
• before closing the cover B again, make sure the rubber cap A is properly
inserted (it must be flush with the outer plastic surface).
• if needing to cut sheet metal, it is recommended to use laser cutting;
• the thickness of the sheet metal or the material used to make the
electrical panel must be suitable to ensure safe and stable installation
of the terminal;
• the tension applied by the screws must not cause deformation of the
sheet metal, so as to not compromise the degree of protection (IP)
shown in the specifications. This degree of protection is guaranteed in
the following conditions: maximum deviation of rectangular opening
from flat surface ≤ 0.3mm, maximum roughness of the surface where
the gasket is applied ≤ 120 m.P
4.2 Installation
Environmental conditions
Avoid installing the controller and the terminal in places with:
• exposure to direct sunlight and to the elements in general;
• temperature and humidity outside the product operating range (see
chapter 12, “Technical Specifications”);
• large, rapid fluctuations in room temperature;
• strong magnetic and/or radio frequency interference (avoid installing
near transmitting antennas);
• strong vibrations or knocks;
• presence of explosives or flammable gas mixtures;
• exposure to aggressive and polluting atmospheres (e.g. sulphur and
ammonia vapours, salt mist, fumes) that can cause corrosion and/or
oxidation;
• exposure to dust (formation of a corrosive patina with possible
oxidation and reduced insulation);
• exposure to water.
Positioning the controller inside the electrical panel
Install the controller inside an electrical panel in a position where it
cannot be reached and it is protected from knocks or impact. The
controller should be placed inside the panel in a position where it is
physically separated from power components (solenoids, contactors,
actuators, inverters, etc.) and their respective cables. The ideal solution
is to house these two circuits in two separate cabinets. Proximity to such
devices/cables may cause random malfunctions that are not immediately
evident. The panel casing must allow an adequate flow of cooling air.
Important:
• for safety reasons the controller should be installed inside an electrical
panel so that the only accessible parts are the display and the built-in
terminal keypad;
• install the controller so that the disconnect devices can be used safely
and without hindrance.
• when laying out the wiring, separate as much as possible the probe
cables, digital input cables and serial line cables from the power cables,
contactors, thermomagnetic devices, in order to avoid electromagnetic
interference;
• never run power cables and probe signal cables in the same conduits
(including the ones in the electrical panels);
• for control signals, use shielded cables with twisted wires. If the control
cables have to cross over power cables, the intersections should be as
close as possible to 90 degrees; under no circumstances should the
control cables be laid parallel to the power cables;
• keep the paths of the probe cables as short as possible and avoid
making spiral paths that enclose power devices;
• in case of malfunctions do not attempt to repair the device, but
contact a CAREL service centre.
Panel installation: c.pCOmini panel version
Procedure:
1. insert the gasket, with the smooth side facing the terminal;
2. place the terminal in the opening;
3. tighten the screws;
4. apply the frame, applying uniform pressure firstly on the 4 corners
(points D) and then on the middle points of the frame (points E), until
it clicks into place.

c.pCO Small...Extralarge
The controller and the terminal are connected to a pLAN network.
1: Connecting the terminal to one c.pCO controller
When connecting the controller to the terminal, the following restrictions
should be kept in mind:
1. the overall length of the pLAN network should not exceed 500 m.
Consequently, if the terminal is installed in a remote position, the
length of the terminal cable must be included in the total length;
2. the unshielded telephone cable can be used for a max. length of
50 m. Beyond this length, use a 3-wire shielded cable (see the table
below);
3. for lengths greater than 200 m, the power supply for the terminal
must be provided separately;
4. no more than 3 terminals (semi-graphic terminals such as pGDs or
touch screens such as pGDT / pGDx) can be connected to the same
c.pCO controller. The terminals must be the same type (e.g. all pGD1).
One terminal is powered by the controller, and the other two by an
external power supply;
5. except PGD0 / PGD1 / PGDE, other terminals must be powered with
separate power supply.
Important:
• in domestic installations, standard EN55014 requires the connection
cable between the controller and the terminal to be shielded, with the
shield earthed at both ends;
• in industrial installations with length >10 m, the connection cable
between the controller and the terminal must be shielded and the
shield must be earthed.
Case A: 1 terminal.
A.1: distance L < 50 m.
The typical connection for one terminal (e.g. PGD1) is made using a 6-wire
telephone cable available from CAREL as an accessory (S90CONN00*).
The telephone connector provides both data transmission and the
power supply for the terminal.
To make the connection:
• plug the connector into terminal J10 until it clicks into place.
To remove the connector:
• press lightly on the plastic catch on the connector and pull it out.

Case C: 3 terminals.
For the first 2 terminals refer to Case B. For the third terminal use one of
connections A.1, A.2 or A.3.
Important:
• the 24 Vdc at +Vterm (J24) can be used only in alternative to connector
J10 to power an external terminal, with maximum current 1.5 W;
• in networks with a star layout, if the cable is longer than 5 m, connect
the terminal only to the first or last c.pCO in the network (to avoid
branches).
The following table applies.

2: Shared terminal connection in pLAN network
To share a terminal between several c.pCO controllers, these can be
connected in a pLAN network, and the terminal connected to one of the
controllers in the network (see the figure below). The previous details on
the maximum length allowed between terminal and controller also apply
in this case.

It is possible use one terminal only, sharing it between controllers to
display the information relating to each (see the paragraph "Private and
shared terminal").
4.6 Input/output labels
c.pCO controllers are distinguished by size and provided with inputs
and outputs and power supplies for the active probes most suitable for
various applications.
The features that depend on the model are:
• maximum number and type of inputs/outputs;
• availability of built-in driver for expansion valves;
• type of interfaces

5.1 Power supply
The figure below shows the power supply connection diagram. Use
a class II safety isolation transformer with short-circuit and overload
protection. See the Technical Specifications table for information on the
size of the transformer required by each model (see chap. 13).

Fig. 5.a
Important:
• power the c.pCO built-in driver with AC voltage only, with the
transformer secondary winding earthed;
• if the Ethernet connection is featured and used, the transformer
secondary must be earthed;
• using a supply voltage other than specified can seriously damage the
controller;
• if the transformer secondary is earthed, make sure that the earth
conductor is connected to terminal G0. This applies to all the devices
connected to the c.pCO through a serial network;
• if more than one c.pCO board is connected to a pLAN network, make
sure that the G and G0 references are observed (G0 must be maintained
for all controllers);
• the power supply to the controller(s) and the terminal(s) should be
kept separate from the power supply to the other electrical devices
(contactors and other electromechanical components) inside the
electrical panel.
Note:
• when the controller is powered, the yellow LED lights up;
• refer to the diagrams in par. 4.4 in case of controllers connected to a
pLAN network and installed in the same electrical panel or in separate
panels.
5.2 Universal inputs/outputs
Universal inputs/outputs are distinguished by the letter U...
They can be configured from the application program for many different
uses, such as the following:
• passive temperature probes: NTC, PTC, PT100, PT500, PT1000;
• active pressure/temperature/humidity probes;
• ratiometric pressure probes;
• current inputs, 0 to 20 mA or 4 to 20 mA;
• voltage inputs, 0 to 1 Vdc or 0 to 10 Vdc;
• voltage-free contact digital inputs and fast digital inputs;
• analogue outputs, 0 to 10 Vdc;
• PWM outputs.
Important:
• the universal inputs/outputs must be pre-configured to handle their
respective signals from the application program;
• the universal inputs/outputs cannot be used as digital outputs.
Max. number of connectable analogue inputs
The maximum number of analogue inputs that can be connected to the
universal inputs/outputs depends on the type used.

Tab. 5.a
Note: the table shows the maximum number of inputs that can be
connected. For example, it is possible to connect to a Small size controller
a maximum of five 0 to 1Vdc inputs related to probes powered by the
controller, and a a maximum of five 0 to 1 Vdc inputs related to probes
powered externally. In any case, maximum number of 0 to 1Vdc inputs
must be 5.
Remote connection of analogue inputs
The table below shows the required cable sizes to be used for the remote
connection of the analogue inputs.
Type of input Cross section for lengths
<50 m (mm2)
Cross section for lengths
<100 m (mm2)
NTC 0,5 1,0
PT1000 0,75 1,5
I (current) 0,25 0,5
V (current) 0,25 0,5
Tab. 5.b
Important:
• if the controller is installed in an industrial environment (standard
EN 61000-6-2) the connections must be less than 10 m long; do not
exceed this length to avoid measurement errors.
• to avoid electromagnetic interference, keep the probe and digital
input cables separate from the power cables as much as possible (at
least 3 cm). Never run power cables and probe signal cables in the
same conduits (including the ones in the electrical panels).

Connecting active temperature and humidity probes
For information on the maximum number of probes that can be connected
see the table at the beginning of this paragraph. The number depends on
the power supply used. The distinction is between probes powered by the
controller (terminal +VDC) and probes powered by an external source, and
also between active probes with voltage or current outputs. For details
on the operating range see the data sheets supplied with the probes. The
controller can be connected to all the CAREL DP* series active temperature
and humidity probes configured for 0 to 1 V or 4 to 20 mA.
Note: in c.pCOmini models it is not possible to manage 0 to 1 Vdc
or 0 to 10 Vdc signals coming from probes powered directy by the
controller.
Important: for temperature probes use the 4 to 20 mA or NTC
configuration, cause 0 to 1 Vdc signal is limited to the 0 to 1 V range and
is therefore not always compatible with the standard 10 mV/°C signal of
CAREL probes (at temperatures below 0 °C or above 100 °C a probe alarm
may be activated).

The fast digital input can be used as a frequency meter. The count is
performed on the rising edge of the pulse. The pulse generator device
will have one digital output with transistor optocoupler, which will be
connected to the input as shown in the figure. For details on the input
signal see the Technical Specifications table (see chap. 12).
Note: the application program shows the frequency values using
specific variables. If the inputs are configured as counters, the counter is
reset by the application program.

These inputs are all optically isolated from the other terminals. They can
work at 24 Vac (+10/-15%) or 28 to 36 Vdc (-20/+10%) (indicated as ID*),
and some at 230 Vac (indicated as IDH*), see as reference figure below.
Note:
• if the control voltage is drawn in parallel with a coil, install a dedicated
RC filter in parallel with the coil (typical ratings are 100 Ω, 0.5 μF, 630 V);
• if the digital inputs are connected to safety systems (alarms), the
presence of voltage across the contact should be taken as the normal
operating condition, while no voltage represents an alarm situation.
This will ensure that any interruption (or disconnection) of the input
will also be signalled;
• do not connect the neutral in place of an open digital input;
• always interrupt the phase.
Important:
• to avoid electromagnetic interference, keep the probe and digital
input cables separate from the power cables as much as possible (at
least 3 cm). Never run power cables and probe signal cables in the
same conduits (including the ones in the electrical panels.
24 Vac digital inputs (c.pCO Small... Extralarge only)
Digital inputs ID... can be controlled at 24 Vac.
Note:
• the digital inputs are only functionally isolated from the rest of the
controller;
• to keep the digital inputs optically isolated a separate power supply is
needed for each input;
• the digital inputs can be powered at a different voltage from the rest
of the controller.
Cable cross-section
For remote connections to the digital inputs (length <50 m), use cables
with a cross-section = 0.25 (mm2)
Important: If the controller is installed in an industrial environment
(standard EN 61000-6-2) the connections must be less than 30 m long. Do
not exceed this length to avoid measurement errors.

230 Vac digital inputs (c.pCO Medium...Extralarge only)
Medium and Extralarge models feature one group of 230 Vac inputs
(terminal J8), while Large models have two groups (on terminals J8 and
J19). Each group consists of two digital inputs that can be powered at 230
Vac, indicated as IDH*, and two inputs that can be powered at 24 Vac/Vdc,
indicated as ID*. The two groups of 230 Vac inputs have double insulation
between each other and between them and the controller. The digital
inputs connected may be the 24 Vac/dc inputs from one group and the
230 Vac inputs from the other. The two inputs of each group have the
same common pole. Functional insulation is provided. In each group, the
digital inputs must be powered at the same voltage (24 Vac, 28 to 36
Vdc or 230 Vac) in order to avoid dangerous short-circuits and/or the
risk of powering lower-voltage circuits at 230 Vac
Note:
• the range of uncertainty of the switching threshold is from 43 to 90 Vac;
• the voltage must be 230 Vac (+10/-15%), 50/60 Hz.

On terminals VG and VG0 the controller provides optically-isolated 0 to 10
V analogue outputs, to be powered externally at the same voltage as the
controller, i.e. 24 Vac or 28 to 36 Vdc. The connection diagram is shown
in the figure below. The 0 V supply voltage is also the voltage reference
of the outputs. See the Technical Specifications table for details on the
output current, output impedance, etc. (see chap. 12).
Note:
• the analogue output can be connected to the CONVONOFF0 module
to convert the 0 to 10 V output into an ON/OFF relay output;
• a 0 to 10 Vdc analogue output can be connected in parallel to other
outputs of the same type, or alternatively to an external voltage
source. The higher voltage will be considered. Correct operation is not
guaranteed if actuators with voltage inputs are connected;
• if optical isolation is not required, the VG-VG0 analogue outputs can be
powered at the same voltage on G-G0: connect G0 to VG0 and G to VG.

c.pCOmini: unipolar electronic valve
The controller incorporates the driver for connection of an unipolar
electronic expansion valve.
Note: to manage the valve, the control algorithm requires 2
probes (1 pressure probe and 1 temperature probe);
Connection example using ratiometric probes (pressure) and NTC
probes (temperature).

Note:
• connect the valve cable shield to the spade connector and then to the
earth;
• for information on the compatibility of valves and refrigerants, see the
Technical Specifications table (see chap. 12) and the EVD Evolution driver
manual.
On the controller with built-in valve driver it is possible to apply the
Ultracap module (accessory P/N PCOS00UC20) . The module is made
with special capacitors called ultracapacitors that close the electronic
valve in case of power failures. The module only powers the driver and
not the controller.
Important: the c.pCO with built-in driver and PCOS00UC20 module
(or EVD0000UC0 external Ultracap module, or EVBAT00400 battery) must
be powered at 24 Vac so that emergency valve closing is ensured in case
of power failures. If the controller is powered with DC voltage it will not
close the valve in case of power failures.
Note:
• the built-in driver replicates all the hardware and logic functions of
the “EVD Evolution” stand-alone driver in case of 1 valve and of the
“EVD Evolution TWIN” driver in case of 2 valves. In other words, it
independently controls one or two electronic expansion valves with
two-pole stepper motors. The only difference with EVD Evolution is
that there are no output relays. For details on the valve control logic,
set-up and installation, see the EVD Evolution manual (+0300005EN for
single driver, +0300006EN for double driver);
• as with EVD Evolution, the built-in driver on the c.pCO controller
is available in the CAREL and the “Universal” versions. “Universal”
models are used to control both CAREL electronic expansion valves,
as well as valves produced by other manufacturers (see the Technical
Specifications table, chap. 12), while CAREL models only control CAREL
valves.

Note: when different relay outputs must be operated consecutively
at very close intervals (e.g. star-delta motor starter) in the order of
hundreds of ms, use relays belonging to the same group, according to
the following table.

Important: using relays that belong to different groups can cause
delays in switching.
5.8 Solid state relay (SSR) digital outputs
c.pCO controllers are also available in versions with solid-state relays (SSR)
for controlling devices that require an high number of switching cycles that
would not be supported by electromechanical relays. These outputs are
dedicated to resistive loads powered at 224 Vac SELV or 28 to 36 Vdc SELV
with max. load current up to 1 A or 230 Vac with max. load current up to
70 mA.

(*) dedicated power supply or same power supply as controller: not in
common with the power supply for other external loads (e.g. contactors,
coils).
Important: in applications with SSR outputs:
• the controller should only power resistive loads with load current less
than maximum declared;
• use an additional external SSR to power inductive loads;
• for AC power supply to resistive loads or external SSRs, use the same
power supply as the controller (connected to terminals G/G0), which
must be dedicated and not in common with the power supply to other
devices in the electrical panel (contactors, coils, etc.)
Note: the SSR load is powered at 24 Vac SELV, 28 to 36 Vdc SELV or
230 Vac; consequently all the other terminals in the group must be
powered at the same voltage due to the absence of reinforced insulation
within the group.

6. START-UP
6.1 Switching on
When the controller is switched on, it runs a test on the secondary display,
lighting up the segments one by one.
6.2 Private and shared terminal
All c.pCO controllers can be connected to each other in a local area
network (pLAN, see Figure 6.a) in order to share one or more terminals.
Shared terminals can show the variables (temperature, humidity, pressure,
I/O, alarms) from just one controller at a time. The terminal does not need
to be connected to the controller during normal operation, but can be
used just for the initial programming of the main parameters. If one or
more terminals are disconnected or malfunctioning, the application
program continues to work correctly on each controller. Generally, the
application program can monitor the status of the network and intervene
as necessary to ensure continuity of the control functions. The gure
below shows a possible pLAN network connection diagram.

All the terminals and controllers in the network must communicate at the
same speed. The speed is adapted automatically.
A maximum of 32 units can be connected, including:
• c.pCO controllers, which run the control program;
• terminals.
Every device belonging to a pLAN network is identied by a unique
address, i.e. a number from 1 to 32. The number 32 can be assigned only to
a terminal. Programs for different applications (e.g. chillers, air-conditioners,
compressor racks, etc.) cannot be automatically integrated into a local
network – they must be congured according to the system architecture
using the CAREL development tool.
Each controller connected to the network can simultaneously manage
up to 3 terminals in the pLAN network (semi-graphic terminals such as
pGDs or touch screens such as pGDT / pGDx). The values are displayed on
the terminals at the same time and not independently, as if the keypads
and the displays were connected in parallel. Because of that, the controller
cannot manage different kinds of terminals at the same time.
Each terminal associated with a certain controller is dened as:
- private (“Pr”) if it displays only the output of that controller;
- shared (“Sh”) if either automatically or from the keypad it can be switched
between various controllers.
Each c.pCO constantly updates the displays on the private terminals, while
the shared terminals (if present) are updated only by the c.pCO that is
controlling the terminal at that time.

c.pCO 5:
Fig. 6.b
In this example, the shared terminal is associated with 4 controllers, but
at this instant only controller 1 can display data and receive commands
from the keypad. Switching between controllers occurs:
1. using a command in the system menu;
2. in sequence (1->2->3->4->1...) by pressing a button dened by the
application program; however it can also be done automatically
when requested by the program. For example, a c.pCO may request
control of the shared terminal to display alarms or, vice-versa,
relinquish control to the next c.pCO after a set time (cyclical rotation).
Data on the number and type of terminals is determined during initial
network conguration and saved in the permanent memory of each
c.pCO controller. Details of the conguration procedure are described
below. See the “Installation” chapter for information on the cables to use
for the electrical connections.
6.3 Setting the controller pLAN address
The controller pLAN address is factory-set as 1.
There are two ways to set a controller address:
1. using button A (see the gure below) located next to the 7-segment
display. This can be accessed using the tip of a screwdriver (ø<3 mm);
2. from the system menu (see Chapter 7).
Displaying the pLAN address
The pLAN address is displayed permanently on the pLAN address display.

Whenever a pGD terminal is connected to a c.pCO, the pGD terminal
displays the corresponding user interface. The command is sent from
the terminal, however it is the controller that executes the operation to
release or acquire the terminal.
Example 1
A: the release command on terminal 21 releases c.pCO 3 from terminal
21, and this is then assigned to c.pCO 1;
B: the release command on terminal 21 releases c.pCO 1 from terminal 21,
and this is then assigned to c.pCO 2.

6.6 Uploading/updating the software
It is possible to load/update the application software of the c.pCO
controllers family with the following methods:
• Update from computer by using c.factory (via USB or Ethernet
connection
• Update via USB ash drive
• Update with le transfer via FTP (see par. FTP commands)
• Update via tERA cloud service
The c.factory software is part of the “c.suite”, but it can be also installed
individually, downloading it from http://ksa.carel.com under “Software &
Support”->“c.suite”.
Update from computer using c.factory
On all c.pCO family controllers, the application program can be uploaded
by using the c.factory software, with direct connection to the controller
via USB cable or Ethernet network. To upload the application program,
proceed as follows:
a) Update from computer using c.factory via Ethernet connection:
Congure the computer and the c.pCO controller so that they belong to
the same LAN (see paragraph 9.2).
1. Open c.factory and select the application program le compiled in
c.strategy tool (“.otr” le extension). The tool will list the congurations
dened in c.design. Select the conguration to be loaded on the
controller and click “next”.

2. Select the les to be loaded onto the controller and click ”Export Ap1”. In
the application package it is possible to include also:
• the Operating System, selecting the specic path;
• the web pages for the c.pCO web server functionality (see Chapter 10).
Fig. 6.l
3. Click “Export” and save the le to a ash drive, under a directory called
“UPGRADE”.
4. Plug the ash drive into the Host USB port and enter the system
menu (see Chapter 7). On the screen, select UPGRADE and then the
application program to be loaded and conrm by pressing enter.

Important:
• Before updating the c.pCO controller via USB connection, check in
the system menu that the Host USB port is enabled (Settings --> USB
Settings --> Pen drive, see Chapter 7).
• Only use ash drives with FAT le system.
• Do not use both USB ports on the controller at the same time.
• Do not use mass storage peripherals that have a current draw more
than 500 mA.
Update with le transfer via FTP
The c.pCO family controllers tted with Ethernet port include an FTP
server that provides access to the public partition of the le system.
Files and directories in this partition can be read, modied, created and
deleted. FTP can also be used to transfer an .ap1 le, for example to
update the image of the operating system or the application program.
This is done using an FTP client, for example “FileZilla”.
To protect the contents of the public le system against unauthorised
access, different users can be created, assigning each a different access
prole, dedicated to each service and adapted to the individual directory
(see Chapter 9). To update via FTP:
1. Open an FTP client (e.g. FileZilla). Enter the IP address of the c.pCO
controller and the access credentials (default user “anonymous”, no
password).
2. Drag & drop the software update le from the directory on the
computer to the “UPGRADE” directory on the c.pCO controller.
Fig. 6.n
Nota: Please use following settings in Filezilla:
• Edit->Settings->Connection-> set timeout in seconds = 0
• Edit -> Settings -> Transfers -> set maximum simultaneous transfers to 1
3. Access the system menu on the c.pCO and select “UPGRADE” (see
Chapter 7).
