c.pCO s0300057EN rel. 1.2 - 29.05.2017

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;

• 

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 
and the appropriate unit configuration during assembly.
