1. INTRODUCTION
• allows developing new application programs according to customer
The pCO5+ is a microprocessor-based, programmable electronic
controller that is fully compatible (hardware and software) with the 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.
specifications;
• wide range of models distinguished by:
- microprocessor storage capacity: 5 or 9 MB;
- size (Small, Medium, Large, Extralarge), for maximum flexibility
depending on the application;
- solid state relay (SSR) digital outputs (24/230 V);
- NO or NC relay outputs;
- USB ports;
- optically-isolated/non-optically-isolated built-in serial ports;
- built-in display.
• various kinds of connectors (spring, screw, etc.).
The pCO5+ controller has been developed by CAREL to provide solutions
to a host of applications in air-conditioning, refrigeration and HVAC/R in
general. It is highly flexible and can be used to make special products on
customer specifications.
(*) function available from Smart Key firmware version 4.0.
In a pLAN network (pCO Local Area Network) the pCO5+ can be connected
to input/output expansion cards (e.g. pCOe), to other pCO5+ controllers,
to all the controllers of the pCO Sistema family and to the terminals of the
pGD range. Up to 32 devices (controllers and terminals) can be connected
together, allowing highly efficient sharing of information. Each device in
the pLAN network can exchange digital or analogue data with all the
others, depending on the application program used.
Main features of terminal
Thanks to the capabilities of the application software, while the unit is
normally working the user terminal can be used to:
• edit the main parameters;
• receive acoustic alerts (from buzzer) and visual alerts (on display) of any
alarms triggered;
• view active functions and measured quantities displayed by LED
indicators.
Compared to pCO3 controllers, pCO5+ units are equipped with two extra
built-in RS485 serial ports – one for the Fieldbus and one for supervision/
telemaintenance purposes (BMS).
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).
1.1
Programmability
The programmable controllers of the pCO family can be programmed
using the 1Tool development software, which offers the following
advantages:
• transferability of software. Applications developed for the pCO can be
quickly and easily transferred between different hardware platforms by
simply modifying the inputs and outputs;
• rapid development of custom programs at competitive costs;
• reliability guaranteed by the use of standard routines, tested in the lab
and in the field.
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 Medium range includes controller versions with 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, and allows
shutting the valves completely in case of power failures (alternating
current).
In addition, using 1Tool provides customers with maximum confidentiality
and ample self-management when developing new programs on their
own. Using the same hardware for different applications enhances
standardization, with the clear advantage of being able to perform incircuit, functional and burn-in tests on all products, thereby ensuring a
high level of reliability in general and in terms of individual electronic
components.
Main features
• the same controller can be connected to up to 3 PGD terminals (semigraphic terminals such as pGDs or touch screens such as pGDT / pGDx);
• the program and parameters are saved permanently in a non-volatile
memory (flash memory), preventing data loss in case of power failures
(without requiring a backup battery);
• 32-bit microprocessor controllers with 5 or 9 MB storage capacity
ensure high performance in terms of speed and memory space;
• allows connecting up to 32 devices to pLAN networks consisting
of a series of pCO5+ controllers and terminals. Each controller can
exchange data with the other controllers at high speed without
requiring additional hardware;
• external or built-in terminal with display and LED-button keypad; can
be used for uploading software and commissioning;
• fast upload/download of controller software using a “Smart Key(*)” or
any pendrive (provided the controller is equipped with the relative
port);
• 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;
• allows using the 1Tool software (installable on a personal computer)
for creating and customising application programs, performing
simulations, supervising operations and setting up pLAN networks;
• allows uploading application software to the controller using the pCO
Manager program, available free of charge at http://ksa.carel.com;
• many dedicated programs available for controlling a variety of HVAC/R
applications;
Applications
When provided with a dedicated application program, the same
controller can be used to control equipment of different kinds:
• chillers and heat pumps;
• roof-top units;
• air-conditioners;
• small/medium-sized air handling units (on request);
• refrigerated counters (on request and to specifications);
• cold rooms (on request and to specifications);
• curing rooms;
• compressor racks;
• universal stage controllers.

1.2 Functional layout
The figure below shows the functional layout of an air handling
unit. Damper actuators and valve actuators are field devices that
communicate through Fieldbus 1 (ref. C). Fieldbus 2 (ref. E) is the medium
through which the serial probes communicate the values measured,
and through which the humidifier control board and the fans exchange
data and receive setpoints from the controller. The built-in terminal and
the remote terminal, which communicate via pLAN (ref. A), are used for
installing the application program and for commissioning the system.
The PGD touchscreen terminal, intuitive and simple to use, can be used
while the unit is normally working to set switch-on and switch-off times,
to enter the main parameters, to perform other advanced functions of
the application program and to view any alarms triggered. In this case the
data is communicated through the BMS2 serial port (ref. D). The system
can be connected to a supervision system (Konnex®, LON®, BACnet™, etc.)
after installing the relative BMS1 expansion card (ref. B).

Compared to the pCO3, pCO5+ (and pCO5) controllers have a second
BMS serial port on connector J25 (BMS2) and a second Fieldbus port
on connector J26 (FBus2). pCO5+ Large and Extralarge boards still have
connector J23, which is marked FBus2 like connector J26. With reference
to management under 1Tool, this is the same serial line, so different
addresses must be used for devices connected to both connectors,
while from the electrical point of view the ports are independent (an
electrical fault on port J26 does not affect port J23). See the “Technical

Important warnings:
• By applying the appropriate impedance, a serial port with Master
(FBus) hardware 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.
• However, no more than two devices with master hardware (FBus) can
be connected to the same network, otherwise the network’s total
bias impedance becomes too small and incapable of supplying the
required voltage to the RS485 network.
• We recommend connecting 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.
3.2 Port J26 configuration
Compared to the pCO5, pCO5+ controllers are provided with 4
microswitches for configuring serial port J26 (figure):
• microswitches all down: port J26 set with Fieldbus hardware;
• microswitches all up: port J26 set with BMS hardware*.
Factory configuration: Fieldbus port.
(*) At the software level, in the 1Tool programming environment the serial
port is still the Fieldbus2.

3.3 Controller network connections
The pCO5+ comes with three kinds of serial ports: pLAN, Fieldbus, BMS.
The RS485 Fieldbus serial port is designed with Master-type hardware,
while the RS485 BMS serial port has Slave-type hardware. The protocols
used on the RS485 Fieldbus port are, due to the nature of the port, Master
protocols (CAREL Master or Modbus RTU Master), although in special
cases Slave protocols can be used (CAREL Slave or Modbus RTU Slave),
adopting the necessary measures. Likewise, Slave protocols are applied
on the RS485 BMS port, although under certain conditions Master
protocols can also be used.
Note: The pLAN network is multi-master, meaning that each
controller can work as Master or Slave at the same time.

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’s range of operation
(see “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 is protected from knocks or impacts. 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’s
casing must allow an adequate flow of cooling air.

4.3 Preliminary operations
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’s keypad.
Install the controller so that the disconnection 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 (connected to contactors, thermomagnetic devices, etc.) 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.
Installing the serial cards
If the Fieldbus and BMS serial cards built into the pCO5+ are insufficient
for the required application, you can add a Fieldbus serial port and a BMS
serial port, which are available as accessories (see chap.1).
To install them, proceed as follows:
1. Locate the Fieldbus or BMS serial port.
2. Using a screwdriver, take off the cover.
3. Using a pair of nippers, cut out the perforated plastic part to create
an opening.
4. Plug the optional card into the edge-card connector, making sure it
is firmly secured and makes contact.
5. Put back the cover so that the serial card’s connector is aligned with
the opening.
6. Make the electrical connections required.

FieldBus card
Electrical installation
Important: Before servicing the equipment in any way disconnect
the controller from the power mains by putting the system’s main switch
on OFF.
Fig. 4.b
Make sure the system is provided with a power disconnector conforming
to regulations. Use cable lugs that are suitable for the terminals used.
Loosen each screw and insert the cable lugs, then tighten the screws.
There is no limit to the number of wires that can be connected to
each individual terminal. When tightening the terminal screws apply
a tightening torque no greater than 0.6 Nm. For information on the
maximum allowable length of the connections to the analogue/digital
inputs and to the analogue outputs please refer to the “Technical
Specifications” table. In environments subject to strong disturbance use
shielded cables with the braiding bonded to the earthing conductor
in the electrical panel. The terminals can accept wires with a maximum
cross-section of 2.5 mm2 (12 AWG). After making the connection, gently
tug on the cables to make sure they are sufficiently tight.
Note: For details, refer to the instructions sheets of the cards to
install.
Installing the pCOe expansion card
See instructions sheet code +050003265.
Installing the Ultracap module
See instructions sheets codes +0500042IE and +0500041IE.
4.4 Serial network electrical connections
To improve the controller’s immunity against electromagnetic
interference, the serial connection cable should be a shielded twisted
pair cable, 2-pole or 3-pole depending on the insulation of the serial
connection. The following rule applies:
• if the serial port is isolated (functionally) from the power supply, a third
wire is required in the serial cable to act as a common reference for the
controllers. If the serial port is not optically isolated and the common
reference is already present, no third wire is required.
Note:
• secure the cables connected to the controller with clamps placed at 3
cm from the connectors;
• if the power transformer's secondary winding is earthed, make sure
the earth conductor is bonded to the conductor that goes to the
controller and is connected to terminal G0. This applies to all the
devices connected to the controller through a serial network.
Technical specifications for connections
Use a shielded, twisted pair cable (AWG 20-22) with inter-conductor
capacitance <90pF/m.
Important:
• Using a supply voltage other than specified can seriously damage the
Master
device
system.
• Connect the fuse close to the controller.
• Installing, servicing and inspecting the controller should be done
•
•
•
•
•
only be qualified personnel and in compliance with national and local
regulations.
All the very low voltage connections (24 Vac/Vdc or 28 to 36 Vdc
analogue and digital inputs, analogue outputs, serial bus connections,
power supplies) must have reinforced or double insulation from the
power mains.
Avoid touching or nearly touching the electronic components
mounted on the boards to avoid electrostatic discharges from the
operator to the components, which can be very damaging.
Do not press the screwdriver on the connectors with excessive force,
to avoid damaging the controller.
Using the device in any way other than specified by the Manufacturer
can compromise its protection system.
Use only optional boards and connectors supplied by CAREL.

This is the case of serial ONE - BMS1, serial TWO - Fieldbus 1 and the builtin ports serials THREE and FOUR on optically-isolated models. Regardless
of the type of power supply or earthing, use a 3-pole shielded cable

4.5 Connecting the terminal
Note: For information on the position of the jumpers on board
TCONN6J000, see instructions sheet code +050002895.
The controller and the terminal are connected to a pLAN network.
1: One 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 remotely 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-pole shielded cable (see table below);
3. in case of 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 pCO controller. The terminals must be of 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 for PGD0/PGD1/PGDE, the other terminals should be powered
by separate power supplies.
A.3: Distance 200< L< 500 m.
The terminal must be powered by an external power supply. Connect a
3-pole shielded cable to connector pLAN J11. Provide a separate power
supply for board TCONN6J000, as shown in the figure.

Case A: 1 terminal
A.1: Distance L < 50 m.
The typical connection for one terminal (e.g. PGD1) is made using a
6-pin telephone cable available from CAREL as an accessory (code
S90CONN00*). The telephone connector provides both data transmission
and the power supply for the terminal.

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.

B.2 Distance 50< L< 200 m.
2: pCO controller in pLAN network
Use 3 TCONN6J000 boards connected as shown in the figure.
If a terminal is connected to a pCO controller which is itself connected
to other controllers in a pLAN network, the terminal is directly powered
by the controller. Be sure to avoid the terminal being powered by two
power supplies. For that purpose, set jumpers J14 and J15 on board
TCONN6J000 to interrupt the supply current.

pCO5+ 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.

When setting up a pLAN network with pCO controllers and terminals,
each pCO5+ controller can power only 1 PGD1/E terminal (except for the
Small model, which can power 2 terminals). When you need to connect
more than one terminal, you will have to provide an independent power
supply. See instructions sheet code +050002895.

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:
• except for pGD1, the other terminals should be always powered by
separate power supplies;
• the 24 Vdc on the +Vterm (J24) terminal can be used only in alternative
to connector J10 to power an external terminal, with maximum current
1.5 W;
• in networks with star layout, if the cable is longer than 5 m connect
the terminal only to the first or last pCO5+ in the network (to avoid
branches).

INPUT/OUTPUT CONNECTIONS
Max. number of connectable analogue inputs
5.1 Power supply
The maximum number of analogue inputs that can be connected to the
universal inputs/outputs depends on the type used.
The figure below shows the power supply connection diagram. Use
a class II safety isolating transformer with short-circuit and overload
protection. See the Technical Specifications table for information on the
size of the transformer required by each controller model.

Important:
power the pCO5+ built-in driver with AC voltage only, with the
transformer’s secondary winding earthed;
using a supply voltage other than specified can seriously damage the
controller;
if the transformer’s secondary is earthed, make sure that the earth
conductor is connected to terminal G0. This applies to all the devices
connected to the pCO through a serial network;
if more than one 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: The table shows the maximum number of inputs that can be
connected. For example, a Small controller can be connected to a
maximum of five 0 to 1 Vdc inputs from controller-powered probes and a
maximum of five 0 to 1 Vdc inputs from externally powered probes. In any
case, the maximum number of inputs of both kinds that can be connected
is 5.
Remote connection of analogue inputs
The table below shows the required cable sizes to use for the remote
connection of the analogue inputs.
Note:
• the yellow LED on the controller lights up when the controller is
powered;
• 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:
• 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 separated 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).
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.

configuration, as the 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

Connecting fast digital inputs
5.3 Digital inputs
Important: The wires connecting the fast digital inputs/counters
must be shielded to avoid causing electromagnetic interference with the
probe cables.
The controller features digital inputs for connecting safety devices,
alarms, device status indicators and remote switches. These inputs are all
optically isolated from the other terminals. They can work at 24 Vac (+10/15%) or at 28 to 36 Vdc (-20/+10%) (indicated with ID*), and some also at
230 Vac (indicated with IDH*).

• if the control voltage is drawn in parallel with a coil, install a dedicated
• 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.

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 two digital outputs with transistor optocoupler, which will be
connected to the inputs as shown in the figure. For details on the input
signal see the Technical Specifications table.
Important:
• to avoid electromagnetic interference, keep the probe and digital
input cables separated 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).
Note: The BIOS shows the frequency values using specific variables.
If the inputs are configured as counters, the application program resets
the counter. The maximum number of pulses is 32767, after which the
counter restarts from zero.
24 Vac digital inputs
The ID... digital inputs can be controlled at 24 Vac.
Example:
Note:
• the digital inputs are only functionally isolated from the rest of the
controller;

• if you want to keep the digital inputs optically isolated you will have to

• the digital inputs can be powered at a different voltage from the rest

Cable section
Fig. 5.k
The cables used for remote connections to the digital inputs should have
the following cross-section:
Cross section for lengths <50 m = 0.25 (mm2)
Nota: in the case of fans with tachometer output with high series
resistance, the reading of the pulses may depend on the current. The
function block ("function block") application program (DIN_COUNT2)
includes a pin for which the default is the current 2mA.
You can also select or 500 uA 50 uA in order to stay within the voltage
values of 0.25 ... 0.85 V to get a correct reading.
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
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 with IDH*, and two inputs that can be powered at 24 Vac/
Vdc, indicated with ID*.
The two groups of 230 Vac inputs have double insulation between
themselves and between them and the controller. The digital inputs that
are connected can be the 24 Vac/dc inputs of one group and the 230 Vac
inputs of the other.
The two inputs of each group have the same common pole. Operational
insulation is used. 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 with 230 Vac electricity.
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.

5.4 Optically-isolated analogue outputs
0 to 10 V analogue outputs
On terminals VG and VG0 the controller provides optically-isolated 0 to
10 V analogue outputs, to be powered externally at the same voltage
powering the controller, i.e. 24 Vac or 28 to 36 Vdc. La figure below
shows the connection diagram. 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.
Note:
• the analogue output can be connected to module code CONVONOFF0
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 source of
voltage. 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.

Serial communication and programming
5.5 Connecting the electronic valve
Communication between the pCO5+ and its built-in driver is managed
internally through the FBus2 serial port. The FBus2 serial port (J26) is
however electrically isolated from the driver’s serial line; this ensures that
in case of external faults on the line connected to FBus2, the internal driver
can keep on working independently. The driver can only be configured
using the pCO5+ application developed with 1Tool; no external displays
are available for the driver.
The controller with a built-in driver can be used to control one or two
electronic expansion valves (depending on the model).
Example of connection diagram (the colour of the wires refers to the
standard CAREL valve cable, code E2VCABS*00).

The 1Tool development environment features a module for managing
the EVD Evolution driver. When managing the internal driver, use the
module as if you were managing an external driver connected to the
FBus2 port.

At the 1Tool application software level, the valve driver must be
connected to the FBus2 port. Consequently, any other devices physically
connected to the Fbus2 port (J26) must have the same communication
protocol (CAREL Standard Master or Modbus® Master), the same baud
rate, stop bits and parity. The CAREL or Modbus protocol is selected
automatically. The internal driver’s address is 198 (EVD Evolution’s default
address), so any other devices connected to J26 must have an address
other than 198. The CAREL or Modbus protocol is selected automatically.
External EVD Evolution drivers can be connected to the Fieldbus1 serial
port (optional card) with no address restrictions.

Important: To ensure efficient data exchange between the driver
and the controller, when developing the 1Tool application, if there are
devices connected to the FBus2 port (terminal J26) using the Modbus®
protocol, developers should take into account the number of variables
exchanged over the entire serial line.
Notes:
• the built-in driver replicates all the hardware and logic functions of the
“EVD Evolution” controller in case of 1 valve and of the “EVD Evolution
TWIN” controller 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 (code +0300005IT for single
driver, +0300006IT for double driver);
• as with EVD Evolution, the internal driver on the pCO5+ controller
is available in the CAREL and the “Universal” versions. “Universal”
models are used to control both CAREL electronic expansion valves
and products made by other manufacturers (see the Technical
Specifications table), while CAREL models only control CAREL valves.

Notes:
• inside each group, the relays have just operational insulation and must
therefore have the same voltage (generally 24 Vac or 110/230 Vac);
• between groups there is reinforced insulation, so different groups can
have different voltages.
pCO5+ controllers are also available in versions with solid-state relays
(SSR) for controlling devices that require an unlimited number of
switching cycles that would not be supported by electromechanical
relays. These outputs are dedicated to resistive loads powered at 224Vac
SELV or 28 to 36 Vdc SELV with max. load current up to 1A or 230 Vac with
max. load current up to 70mA.

1. the controller should drive only resistive loads with loads current less
than maximum declared;
2. use an additional external SSR to drive inductive loads;
3. for AC power supply to resistive loads or external SSRs,
4. use the same power supply as the controller (connected to terminals
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.

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.

All pCO5+ controllers can be connected to each other and to other
CAREL devices in a pCO local area network (pLAN) without requiring
optional devices, allowing the communication of data and information
from one location (node) to another. The 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
the continuity of control functions. The figure 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 adjusted automatically.
A maximum of 32 units can be connected, including:
• pCO controllers, which run the control program;
• external modules, which provide extended functionality (such as the
EVD Evolution driver);
• terminals.
Every device belonging to a pLAN network is identified by an 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 configured according to the system’s 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 drive different kinds of terminals at the same time.
6.3 Setting the controller’s address
The controller’s pLAN address is factory-set as 1.
There are two ways to set a controller’s address:
1. using the A button (see figure below) located on the left of the
7-segment display. It can be accessed using the tip of a screwdriver
(ø<3 mm);
2. using a terminal connected to the pLAN network.
1. Displaying the pLAN address
Procedure:
• briefly press the A button (no more than 5 s) to display the controller’s
current pLAN address. Five seconds after releasing the button the
display is cleared.
FB
Each terminal associated with a certain controller is defined 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.
FieldBus card
G
J1
Each pCO constantly updates the displays on the private terminals, while
the shared terminals (if present) are updated only by the pCO that is
controlling the terminal at that time.

In this example the shared terminal is associated with 4 pCO controllers,
but at this instant only controller 1 can display data and receive commands
from the keypad. Switching between controllers occurs in sequence (1>2->3->4->1...) by pressing a button defined by the application program;
however it can also be done automatically when requested by the
program. For example, a pCO may request control of the shared terminal
to display alarms or, vice-versa, relinquish control to the next pCO after a
set time (cyclical rotation).
Data on the number and type of terminals is determined during initial
network configuration and saved in the permanent memory of each pCO
controller. Details of the configuration procedure are described below.
See the “Installation” chapter for information on the cables to use for the
electrical connections.

2. Setting the address using an external terminal
The controller is assigned a private (Pr=private) or shared (Sh=shared)
terminal with address 32. The external terminal can be given an address
from 0 to 32. Addresses between 1 and 32 are used by the pLAN protocol,
while address 0 identifies the Local Terminal protocol, used for point-topoint connections and to configure the controller (this can be done with
a single pGD terminal and a single pCO).
If the controller with default setting (address=1) is connected to an
external terminal (address=32), communication is established and the
external terminal replicates the display on the built-in terminal, if featured.
If however the controller has a different address (e.g. 7) and the terminal
is not set to communicate with the controller at this address, once the
connection is established the terminal will display a blank screen.
In this case, proceed as follows.
5.
Using the UP and DOWN buttons, set the controller’s pLAN address
to 7 and press Enter to confirm.
pLAN address: 7
UP: increase
DOWN: decrease
ENTER: save & exit
Fig. 6.i
Procedure:

6.5 Uploading software
Fig. 6.o
The following methods can be used to update the firmware and acquire
the log files on pCO controllers:
• smart Key programming key;
• pCO Manager, a program to install on the PC;
• a pendrive.
The controller can be connected directly to the PC via the RS485 serial
port used for the “pLAN” connection or via the BMS or Fieldbus serial port
using the optional RS485 serial card. Lastly, connection can be made
using the slave USB port, if present.
pCO Manager can communicate with all the programmable controllers
of the pCO family. The program can also be used to update and download
to the PC the BOOT, BIOS, application program, configuration and log files
and also to save files to the NAND flash memory.
If you are using a pendrive, before proceeding you must connect the
terminal to the controller following the instructions in par. 4.5 and then
establish the connection. The terminal can be either private or shared.
As a rule, CAREL advises NOT to update the BOOT; CAREL always loads the
BOOT best suited for the controller’s operation during construction. Only
in very special cases will CAREL ask the user to update the BOOT.
The BIOS can only be updated via the pLAN serial connection. This
procedure causes the controller to switch to low-level operation. In this
operating mode log data cannot be downloaded to the PC. To bring the
controller back to normal communications with pCO Manager, reset
the pCO after successfully loading the BIOS. For further information on
the operation of pCO Manager see the online help inside the program.
Download options are shown in the table below.
Smart key
The PCOS00AKY0 key is an electronic device used to program and service
pCO Sistema controllers. The PCOS00AKY0 key simplifies data transfer
between the controllers installed and a personal computer by exploiting
the high capacity flash memory for storing software applications, BIOS
and variable logs. The pCO is connected directly via the telephone
connector using the cable supplied, while to transfer data to a personal
computer the PCOS00AKC0 USB adapter is required. The device is
powered either by the USB port on the PC or by the controller, therefore
no external power supply is necessary.

NAND flash memory
Upload and Download
This type di memory is included on all pCO5+ controller versions. pCO
Manager can be used to load any type of file to the NAND flash memory.
It can be used, for example, to save the source files of the application
program being used.
In addition, the IUP, BLB (or BIN) and DEV files that represent parameter
files, the screens displayed in the various languages and the control
logic can be loaded to the NAND flash memory and then selected from
the terminal screen to be used as the current application on the pCO.
Specifically, several different applications, or different languages, or
multiple parameter files can all be loaded in the NAND flash memory,
after which the desired application, language or parameter configuration
can be selected and loaded to the main flash memory. The files saved in
the NAND flash memory can be selected and copied to the main flash
memory on the screen managed directly by the BIOS. The procedure is
described in paragraph 6.6.
Limitations:
• a maximum of 40 files can be saved on the NAND flash memory;
• the memory’s total storage capacity is 50 MB.
UPLOAD can be performed in three different ways:
1. manual mode: the user selects manual mode from the keypad, then
the files to load, and then confirms to start the operation;
2. automatic mode: the user selects automatic mode from the keypad
and then the configuration files containing the instructions on the
operations to carry out;
3. autorun mode: after the pendrive is plugged in, a screen is displayed
indicating that Autorun mode has started. After confirming, the
instructions contained in “autorun.txt” are executed automatically.
The contents of this file are similar to the UPLOAD configuration files,
the only difference being the name “autorun.txt”.
DOWNLOAD can be performed in two different ways:
1. manual mode: the user selects manual mode, then the files to
download, and then confirms to start the operation;
2. autorun mode: after the pendrive is plugged in, a screen is displayed
indicating that Autorun mode has started. After confirming, the
instructions contained in “autorun.txt” are executed automatically.
The contents of this file are similar to the DOWNLOAD configuration
files, the only difference being the name “autorun.txt”.
Pendrive
Some controller models come with two different USB ports (host and
slave) to be used for installation and diagnostics. The host port can be
used to connect USB mass storage peripherals (pendrives, portable hard
disks, etc., having a maximum current consumption of 500 mA) with
which to carry out various operations:
1. upload to the controller files contained in the removable peripheral
(e.g. application, parameters in the buffer memory, configuration files
for logs, BIOS);
2. download files from the pCO5+ to the removable peripheral (e.g.
application, parameters in the buffer memory, data logs, BIOS).
Note: The configuration and autorun files must reside in the main
directory.
The steps to follow are described in par. 9.3.
6.6 Checking the software installed and
other information
Users can at any time check the version of the current program (by CRC
code, expressed in hexadecimal), and also whether it is being used by the
key or by the resident program. To do this, proceed as follows.
Note: Using the pendrive to perform the following operations:
• UPLOAD - copying files from the pendrive to the controller;
• DOWNLOAD - copying files from the controller to the pendrive is

possible only when using a terminal, either built-in or connected to
the controller via pLAN.
Press the ALARM and ENTER buttons together for 3 seconds. The following
screen will appear.
The controller can be provided with 2 USB ports which can be accessed
by removing the cover (see chap. 2).

Each of the four lines displayed is used to access further screens, managed
by BIOS and consequently always available regardless of the application
loaded. To access the functions, select the line with the cursor “>” using
the UP and DOWN buttons and then press ENTER to confirm. To exit the
screen press MENU or Esc on the terminal, or wait around 40 seconds for
automatic timeout.
The screens provide the following information.
Important
• before the pendrive can be used it must be formatted to the FAT32
file system;
• the pendrive can be accessed up to two levels – APPL\CHILLER\PRI.BIN
– but access to file \APPL\CHILLER\VER1\PRI.BIN is not allowed;
• do not use both USB ports at the same time;
• the maximum pendrive capacity supported is 32 GB.

the keypad; this offers maximum flexibility and the possibility to freely
decide which operations to perform;
• automatic mode requires creating special files called configuration
files. These are text files (.txt extension) containing various types of
information on the functions to perform and the files to load;
• autorun mode requires creating a special configuration file called
“autorun.txt”. When the pendrive is plugged, in the controller
immediately executes Autorun and upon confirmation from the
terminal performs the operations contained in the file.

The first line displays the BOOT version and date. In the example shown,
the pCO is working with BOOT 4 dated 6 December 2011. The second
line displays the BIOS version and date. In the example shown, the pCO
is working with BOOT 6 dated 13 January 2012. The fourth line displays
the application CRC and the amount of flash memory occupied. In the
example, the application’s CRC value is 3617. If this line shows 1 MB, a pCO
with 1 MB flash is sufficient. The CRC is a number that summarises the
application contained in the pCO’s flash memory, but also other system
information. It is therefore recommended to note the version of a specific
application by checking the screen on which it is displayed.

Attention:
• To avoid irreparably damaging the controller, externally powered active probes (0 to 1 V, 0 to 10 V, 0 to 20 mA, 4 to 20 mA) should be provided
with adequate current protection and the current should be <100 mA.
• Ratiometric probes can be powered by the controller only.
• at power on, universal inputs/outputs are short circuited to GND for about 500ms up to the end of the configuration.

Notes:
• to avoid electromagnetic interference, separate as much as possible the probe and digital input cables from the cables carrying inductive loads and the power
cables. Never run power cables and probe signal cables in the same conduits (including the ones in the electrical panels);
• the two 230 Vac or 24 Vac/Vdc inputs on terminals J8 (ID13, ID14) or J19 (ID15, ID16) have the same common pole and must therefore be powered at the same

controller;

Warnings:
• for lengths greater than 10 m use a shielded cable with earthed shield;
• a 0 to 10 Vdc analogue output can be connected in parallel to other outputs of the same kind, or alternatively to an external source of voltage. The higher voltage
will be considered. Correct operation is not guaranteed if actuators with voltage inputs are connected;
• power the VG-VG0 analogue outputs at the same voltage on G-G0: connect G to VG and G0 to VG0. This applies in case of both alternating or direct current power

The relay outputs have different features depending on the controller model. The outputs can be divided into groups. Relays belonging
to the same group (individual cell in the table) have operational insulation and must therefore be powered at the same voltage.
Between groups (between cells in the table) there is reinforced insulation, so the relays can be powered at different voltages. There is
also reinforced insulation between each terminal of the digital outputs and the rest of the controller.

• to power external loads, use the same power supply as the pCO (connected to terminals G-G0); this must always be dedicated and not in common with the
power supply to other devices (e.g. contactors, coils, etc.);
• to simplify wiring, the groups of digital outputs have two common pole terminals;
• make sure that the current running through the common terminals does not exceed the rated current of each terminal, i.e. 8A.

When the user has finished using Commissioning, whether for configuration
or monitoring purposes, the following files can be generated:
• <nomeApplicativo>.2CW [<ApplicationName>.2CW] (descriptor for
categories, access profiles, monitoring groups)
• <nomefileCommissioningLog>.CSV [<FilenameCommissioningLog>.
CSV] (file used for the commissioning log, containing data of the
variables logged during monitoring)
Therefore, to configure Commissioning the following files are required: .2CF,
2CD and, if necessary, the .DEV file, which can be imported or exported.
For monitoring purposes, in addition to the files above, it might also be
necessary to have the .2CW file, containing the definition of the work
environment. The commissioning log file is a simple output file.
pCO Load: basic concepts
pCOLoad is the module that manages:
• uploading to the flash memory (of the device or of the ProgKeyX key
installed on the pCO);
• uploading to the NAND memory of certain devices;
• downloading the log file, .DEV file and P memory (from the flash
memory);
• downloading files from the NAND memory, if present.
Fig. 9.j
Click on “Salva” [Save] to generate the project’s “.2cw” file.
Commissioning: basic concepts
Work carried out with Commissioning is preceded by configuring the work
environment, which is typically done by the project designer. The active
project in 1Tool is automatically loaded by pCO Manager.
The files exchanged with the Flash memories of pCO controllers are:
• BOOT.BIN (download reserved, upload enabled from menu)
• BIOS.BIN (download reserved)
• <nomeApplicativo>.BLB
[<ApplicationName>.BLB]
(download
reserved)
• <nomeApplicativo>.BIN [<ApplicationName>.BIN] (download reserved)
• <nomeApplicativo>.DEV [<ApplicationName>.DEV]
• <nomeApplicativo>.GRT [<ApplicationName>.GRT] (upload only, from
which the .GRP file is extracted)
• <nomeApplicativo>.IUP [<ApplicationName>.IUP]
• <nomeApplicativo>.LCT [<ApplicationName>.LCT]
• <nomeApplicativo>.PVT [<ApplicationName>.PVT]
• <nomepCOlog>.BIN, <nomepCOlog>.CSV, <nomepCOlog_GRAPH>.
CSV
[<pCOlogName>.BIN,
<pCOlogName>.CSV,
<pCOlog_
GRAPHName>.CSV] (only if log files have been configured, download
only).
The project designer can use the configuration functions of Commissioning
to decide which variables should be subjected to monitoring, logging,
trend-monitoring and event-monitoring, to organize variables into
categories and to create sets of configuration parameters.
The files exchanged with the NAND memories of pCO controllers are:
• any file that the pCO can independently copy to the flash memory (see
above list);
• external files (e.g. .pdf or .doc files for documentation).
Operators using Commissioning for maintenance will be able to see the
necessary variables and to draw from preset configuration values.
LogEditor: basic concepts
Note: The following paragraphs are from the online help of pCO
Manager, to which the user is referred for further details.
Commissioning is a configuring and real-time monitoring software that
can be used to supervise the performance of an application program
installed on a pCO, to start up the pCO and to perform debugging and
maintenance.
With this software the user can set the configuration parameters, edit the
values of volatile and permanent variables, save on file the trends of the
unit’s main quantities, manually manage the unit’s I/O using simulation files
and monitor/reset the alarms of the unit on which the device is installed.
LogEditor is the module used to configure the log files of pCO devices
(pCO logs). Configuring pCO logs consists in defining a number of sets
of variables in which to specify which variables should be logged, the
logging method (by frequency or by event) and the minimum number
of loggings required. Configuration is based on a binary file (.PVT – Public
Variable Table), which is generated by 1Tool and contains the descriptive
data of the variables that can be logged.
Support files
Once the design of the application is completed, 1Tool generates a
number of files in the compiling stage, two of which are required by
Commissioning:
• <nomeApplicativo>.2CF [<ApplicationName>.2CF] (variable descriptor)
• <nomeApplicativo>.2CD [<ApplicationName>.2CD] (category and
access profile descriptor)
All the log configurations so defined are saved in the .LCT (Log
Configuration Table) binary file, which must be uploaded to the pCO
together with the .PVT file. Log configuration data is also saved in a file
that can be used only by LogEditor – the .LEF file, which must be saved to
be edited with LogEditor as necessary.
In addition to these files, the software also manages the <nome
applicativo>.DEV [<Application Name>.DEV] file, which contains the unit’s
preset parameters.
LogEditor can be used even when the device is not connected.
Once the files for logging are uploaded to the pCO, the pCO
saves the logged data in the following files:
• .BIN file containing all the data in binary format;
• .CSV file containing the same data in a generic format with values
separated by commas;
• *_GRAPH.CSV containing the same data to be used for charting purposes

Menu access
The following are the steps for accessing the pendrive management
menu. Procedure:
1. Connect the pendrive to the master port.
9.3 Pendrive: operating instructions
File extensions, names and contents
Various types of files can be uploaded and downloaded and are
distinguished by their extension.
File names
In order to be recognised, the names of the directories and files on the
pendrive must have no more than 8 characters; the controller makes no
distinction between upper-case and lower-case characters. However,
during DOWNLOAD the names of the directories created by the controller
on the pendrive are always in upper-case.

Example: A directory named LOG00_01 contains the log files (LOG)
downloaded from a device whose pLAN address is 1. Since the key
contained no directory of this type before download, it is indicated with
00.
Important: No more than 100 files of the same type can be
downloaded to the pendrive, as the directories created can only be
numbered with XY=00 to 99.

Important: Wait a few seconds after the pendrive has been
plugged in for it to be recognised by the controller. If the message “No
USB disk or PC connected” is displayed momentarily with the request to
connect a pendrive key or computer USB cable, wait a few seconds until
the recognition message is shown (“USB disk found”) and the following

Upload in autorun mode
From to BIOS 6.24 version, it is possible to do the UPLOAD in AUTORUN
mode; without biult-in terminal using the display pLAN address.
Uploading in autorun mode is a special case of uploading in automatic
mode. Unlike automatic mode, the user must wait for a specific message
to appear on the display to start or disable the operation described in the
configuration file. To upload a file in autorun mode, a configuration file
must be created and named “autorun.txt”.
Example of uploading BIOS+application. The upload involves two steps:
first the BIOS is updated and then the application.
The information is shown on the pCO’s built-in display and on the pGD1
terminal, when both are featured.

Important: As can be seen, when updating the BIOS and the
application, the pGD1 terminal shows the message “NO LINK”, meaning
that no connection is established. Do not remove the terminal and wait
for the end of the update procedure, when the pGD1 terminal replicates
the messages on the built-in display.
Note: Autorun run is especially useful in those cases in which the
same operation needs to be performed on several controllers. For
example, to load different applications on controllers connected in a
pLAN network, only one autorun file needs to be created; this uploads
the various directories contained on the pendrive based on the address
of the controllers. The controller with address XY will only load the
directory called “nomedir_XY” [“DirName_XY”]. The pendrive then only
needs to be plugged into each controller to run the upload, confirming
from the shared terminal.
Fig. 9.af
Example: On the controller with address 1, the autorun file will create a
directory called BKP00_01 and copy the files APPL_PCO.DWL and FILE_
DEV.DEV to this directory.
Setting the password
If the application contains a password that must entered in a special
screen, this is requested for each DOWNLOAD/UPLOAD between the
pCO and the pendrive. The password is used to:
• protect the contents of the pCO from being downloaded to the
pendrive;
• protect the PC connection (this is a standard procedure in pCO
Manager).
Manual upload
To manually upload the contents of the pendrive the user must access
the management menu from the system screens, selecting UPLOAD and
then MANUAL. The files are selected by pressing ENTER when the cursor
is on the desired file name. A selected file is marked by the symbol “*”
on the left. Once the files have been selected (all in the same directory),
press PRG to start the upload. To display the contents of a directory press
ENTER. To go up one directory level press ESC. Once the upload has
started, the messages shown on the screen are the same as in automatic
and autorun mode.
Connecting to a computer
Connect the slave USB port on the controller to the USB port on the
computer where pCO Manager is installed.
Download
As mentioned above, the DOWNLOAD operation can be managed in two
ways:
1. Manual mode: follow the steps described in the paragraph
“Automatic upload” and select manual operation. Then each file
must be selected and downloaded.
2. Autorun mode: prepare a file called “autorun.txt”, containing a string
that identifies the function to be performed.

9.4 Configuring pCOWeb/pCOnet from a
system screen
See par. 6.6 for information on how to access the BIOS system menu.
Starting from:
• BIOS release 5.16 BIOS, and from
• pCOWeb firmware version A1.5.0, and from
• pCOnet firmware version A485_A1.2.1
pCOWeb and pCOnet communication parameters can be configured.
The purpose is to configure the network (Ethernet for pCOWeb, RS485
for pCOnet) when the respective card is installed for the first time. The
remaining parameters (alarms, events, etc.) can be configured using the
usual tools, i.e. BACset or web interface (pCOWeb only). Configuration
can be done either when using the Modbus protocol or the CAREL
protocol, but only on the BMS1 serial port. The screens for configuring
pCOWeb and pCOnet can be opened by accessing the system screens
and selecting OTHER INFORMATION and then PCOWEB/NET CONFIG.
Then, select “PCOWEB settings” to configure pCOWeb parameters or
“PCONET settings” to configure pCOnet parameters.
When you select “PCONET settings” the following screen will appear:

After a short time the fields are populated with the current parameters.
If the fields are not populated with the current parameters, check the
firmware version of pCOWeb and the protocol used by the BMS serial
port. The parameters can now be edited by selecting the respective
fields using the ENTER button and setting the desired values using the
UP/DOWN buttons. If the DHCP option is set to ON, the IP address and
Netmask fields cannot be changed. Pressing ENTER repeatedly will display
