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 exibility allows for creation of tailor made control solutions according to customer specications. 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 eld 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 eld-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 oating 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 dierent 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);

• le server (FTP): the c.pCO public le 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) les exported by the datalogger can be downloaded

• creation of accounts with dierent 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 prole (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 notication, 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 rewall 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 ash 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 ash 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 congurable via an application program,

for connecting active and passive probes, digital inputs, analogue and PWM outputs. This extends the possibilities of conguring 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 conguring the Ethernet network;

• wide range of models that dier in terms of:

• size (mini, Small, Medium, Large and Extralarge), to ensure maximum exibility 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 dierent skills to work in a group on the same project, increasing eciency and adopting joint development based on workow. 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, oating 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: denition of congurations, 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 conguration during assembly.

Applications

When provided with a dedicated application program, the controller can be used to control dierent kinds of equipment:

• chillers and heat pumps;

• roof-top units;

• air-conditioners;

• small/medium-sized air handling units (on request);

• refrigerated showcases (on request and to specications);

• cold rooms (on request and to specications);

• curing rooms;

• compressor racks;

• universal stage controllers.

1.1 Functional layout

The gure below shows the functional layout of an air handling unit. Damper actuators and valve actuators are eld 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 humidier control board and the fans exchange data and receive set points 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-o times, to enter the main parameters, to perform other advanced functions of the application program and to view any alarms triggered. In this case data are exchanged via Ethernet port (ref. D). In the same network it is possible to connect another c.pCO controller as well as to communicate with remote cloud service tEra or to BACnet™ supervisor. The system can be connected to other supervision systems (Konnex®, LON®, etc.) after installing the relative BMS1 expansion card (ref. B).

3. COMMUNICATION PORTS

3.1 Serial ports

c.pCO Small...Extralarge

The controllers come with ve serial ports:

• a terminal port on connector J10-J11 (pLAN)

• a built-in BMS port on connector J25 (BMS2)

• a built-in Fieldbus port on connector J26 (FBus2).

• a BMS port to be used with the c.pCO family BMS expansion card (BMS1)

• a FieldBus port to be used with the c.pCO family BMS expansion card (FBus1)

On the c.pCO Large and Extralarge version, connector J23 is available, marked FBus2, in the same way as connector J26. From the point of view of application program management, this is the same serial line, so dierent 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 aect port J23). See the “Technical Specications” table (chap.

12).

c.pCOmini

The controller features:

• a terminal port on connector J3 (Disp.)

• a built-in BMS port on connector J6 (BMS, only on the c.pCOmini Enhanced

model)

• a built-in Fieldbus port on connector J4 (FBus, on the c.pCOmini Enhanced and

High End models).

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 trac not addressed to the controller. If the controller is not powered, pass-through between the two ports will be interrupted. 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 gure 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 gure 3.c).

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 eld devices

to an optically-isolated version of the Fieldbus serial port or to serial port TWO – Fieldbus 1 to exploit the ltering 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 120, 1/4W terminating resistors to the rst 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.

4.1 Mounting and dimensions

All models in the c.pCO family can be mounted on a DIN rail, except for the c.pCOmini panel version.

DIN rail assembly: c.pCOmini, c.pCO Small...Extralarge

The following gure shows the dimensions of the c.pCO controllers, according to the model.

Mounting:

• place the controller on the DIN rail and press it down gently. The tabs

at the back will snap into place and lock the controller.

Removing:

• lift the tabs using a screwdriver applied to their release slots. The tabs

are kept in place by springs.

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 Pm.

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 Specications”);

• large, rapid uctuations in room temperature;

• strong magnetic and/or radio frequency interference (avoid installing

near transmitting antennas);

• strong vibrations or knocks;

• presence of explosives or ammable 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 ow 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 rstly on the 4 corners

(points D) and then on the middle points of the frame (points E), until it clicks into place.

ENG

c.pCO sistema +0300057EN rel. 1.2 - 29.05.2017

Electrical installation

Important: before servicing the equipment, disconnect the controller

from the power mains by moving the system main switch to OFF.

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 Specications” (chapter 12). In environments subject to strong disturbance use shielded cables with the braiding bonded to the earthing conductor in the electrical panel. After making the connection, gently tug on the cables to make sure they are suciently tight.

Note:

• secure the cables connected to the controller with clamps placed at

3cm from the connectors;

• if the power transformer 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.

Important:

• using a supply voltage other than specied can seriously damage the

system;

• connect the fuse close to the controller;

• the controller should only be installed, serviced and inspected

be qualied personnel and in compliance with national and local regulations;

• all the extra 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 may cause considerable damage;

• do not press the screwdriver on the connectors with excessive force, to

avoid damaging the controller;

• using the device in any way other than specied by the manufacturer

can compromise its protection;

• use only optional boards and connectors supplied by Carel.

4.3 Preliminary operations

Installing the serial cards

If the Fieldbus and BMS serial cards built into the c.pCO are insucient 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:

• Locate the Fieldbus or BMS serial port.

• using a screwdriver, take o the cover;

• using a pair of nippers, cut out the plastic knock-out to create an

opening;

• plug the optional card into the edge connector, making sure it is rmly

secured and makes contact;

• put the cover back so that the serial card connector is aligned with

the opening;

• make the required electrical connections.

RS485 network

To improve the controller immunity against electromagnetic interference, the serial connection cable should be a shielded twisted pair cable, 2-wire or 3-wire depending on the isolation 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.

For the RS485 network, use a twisted pair cable with the specications shown in the table.

Case 2: multiple boards connected to a Master/Slave network powered

by dierent transformers (with G0 not earthed); this is a typical application of multiple boards inside dierent electrical panels. If the network is more than 100 m long, the 120 , ¼ W terminating resistor is required.

Important: the earth connection (if any) should be made only on

one point of the earth line (same earthing terminal for all controllers).

The procedure for earthing the shield is described in the corresponding paragraph.

Optically-isolated serial port

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-wire shielded cable connected as shown in the gure. If the network is more than 100 m long, the terminating resistor is required.

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 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.

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 rst 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 rst or last c.pCO in the network (to avoid branches).

5. INPUT/OUTPUT CONNECTIONS

5.1 Power supply

The gure below shows the power supply connection diagram. Use a class II safety isolation transformer with short-circuit and overload protection. See the Technical Specications 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 specied 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 congured from the application program for many dierent 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-congured 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 ve 0 to 1Vdc inputs related to probes powered by the controller, and a a maximum of ve 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 (mm

)

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 congured 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 conguration, 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 gure. For details on the input signal see the Technical Specications table (see chap. 12).

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 gure below.

Note:

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

RC lter in parallel with the coil (typical ratings are 100 , 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 dierent 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 (mm

)

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.

c.pCO Small...Extralarge: 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 as the controller, i.e. 24 Vac or 28 to 36 Vdc. The connection diagram is shown in the gure below. The 0 V supply voltage is also the voltage reference of the outputs. See the Technical Specications 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.

Note:

• for information on the compatibility of valves and refrigerants, see the

Technical Specications 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 dierence 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 Specications table, chap. 12), while CAREL models only control CAREL valves.

ENG

c.pCO sistema +0300057EN rel. 1.2 - 29.05.2017

Serial communication and programming

Communication between the c.pCO Medium 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 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 congured using the c.pCO application developed with c.suite; no external display is available for the driver.

The c.suite development environment features a module for managing the EVD Evolution driver. When managing the built-in driver, use the module as if managing an external driver connected to the FBus2 port.

At a c.suite 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 built-in driver address is 198 (EVD Evolution default address), so any other devices connected to J26 must have an address other than 198. Communication frame conguration is performed by using c.suite environment. External EVD Evolution drivers can be connected to the Fieldbus1 serial port (optional card) with no address restrictions.

Important: to ensure ecient data exchange between the driver and the controller, when developing the c.suite 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.

Note:

• inside each group, the relays have just functional insulation and must

therefore have the same voltage (generally 24 Vac or 110/230 Vac);

• between groups there is reinforced insulation, so dierent groups can

have dierent voltages.

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.

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.

Fig. 6.a

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 dierent 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. 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 dierent 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.

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.

6.4 Setting the terminal address and connecting

the controller to the terminal

After setting the controller network address (see previous paragraph), to establish connections between the controller and the terminal, the terminal address needs to be set. If the controller is connected to an external terminal with address 32 (default setting), communication is established (if the built-in terminal is present, the external terminal replicates the same visualization). To congure multiple terminals, private and/or shared, dierent addresses need to be assigned to the terminals,

and the controller must be properly congured:

1. To congure the address of the terminal, press the UP, DO WN and Enter

buttons together for 3 seconds. The screen is displayed in Fig 6.e. Modify the address of the terminal (in the range 1 to 32) and conrm by pressing Enter.

2. A screen is displayed showing the list of the terminals congured.

Set the terminals as private (Priv) or shared (Shared) according to the application, and conrm to exit. After a few seconds, the connection will be established.

3. To add a second terminal, repeat the previous steps.

6.5 Sharing terminals in a pLAN network

Once connected in a network (pLAN), the c.pCO controllers can share the same pGD terminal. A shared terminal may be needed, for example, to install an update to the operating system and/or application program. Connect the controllers and terminals to the network (Figure 6.g). Set the pLAN address for each controller using the dedicated button (see paragraph 6.3), and for each terminal using the corresponding procedure). The gure below represents three c.pCO controllers in a pLAN network with three pGD displays, each with their own address.

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, dierent users can be created, assigning each a dierent 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.

Important: Power supply to the product must only be connected between G and G0. The Vbat terminal is only used for connection to the Ultracap module as emergency power supply in the event of a power failure.

The dipswitches can be used to set the expansion board serial address (from 1 to 15), protocol (Modbus or Carel) and baud rate. By serial connection it is possible to modify the electrical conguration of the line and assign a serial address from 16 to 247 (207 if using the Carel protocol).

Baud rate and communication protocol settings

Board default conguration is baud rate 19.2 Kbps and Modbus protocol. The “Baud” and “Prot” dipswitches (see Fig. 6.u) can be used to set the baud rate and the communication protocol used by the expansion board. The unit must be switched o before making the settings on the dipswitches.

Important: if the baud rate and protocol settings are changed on the dipswitches while the unit is on, this must be restarted to activate the new settings.

Address and serial communication mode settings

To assign to the board a serial address from 1 to 15, simply set the dipswitches as shown in Figure 6.u. The “Ext” dipswitch must be set to “OFF” (no oset). The unit must be switched o before making the settings on the dipswitches.

Important: if the settings are changed on the dipswitches while

the unit is on, this must be restarted to activate the new settings.

To assign to the the board a serial address from 16 to 247 and to congure the serial communication settings, an oset needs to be sent to the expansion board via serial communication, which is then added to the “Address” dipswitch conguration, and the variable corresponding to the serial transmission parameters needs to be set, as follows:

Example (address setting N=87, serial communication 8, Even, 1):

1. Set the dipswitches of the “Address” group and the dipswitch “Ext.”

a OFF.

2. Restart the unit. The c.pCOE will go into “Set Mode”. Warning:

activating this mode resets both the address oset and the serial communication settings. In this mode, the board serial address will

be 207 and the serial conguration will be 8 bits, no parity and 2 stop bits (8 bits, None, 2). The yellow LED ashes.

3. To set the communication parameters, the “Serial Transmission

Conguration” variable needs to be set via serial communication (see Table 6.a and 6.b). In this example, the variable is set to 5 (conguration 8, Even, 1).

4. To set the serial address, the “Address Extension” oset variable needs

to be set via serial communication (the oset must be greater than 14, see Table 6.a). In this example, it can be set to 86.

5. Move the “Ext” dipswitch to ON. Set the “Address” dipswitches to a

value greater than 0. In this example, the value is set to 1.

6. Restart the unit. After restarting, the expansion card will be

congured with the serial address calculated as the sum of the value set for the “Address Extension” variable and the value set on the “Address” dipswitches (in this example 86 + 1 = 87). After restarting, the expansion card will have the serial communication conguration 8, Even, 1.

8. PROTECTION: PASSWORD AND DIGITAL SIGNATURE MANAGEMENT

The c.pCO controller implements protection methods aimed at preventing unauthorised personnel from performing certain sensitive operations like updating the software, accessing the system menu, cloning proprietary software, etc.

It is possible to protect the c.pCO controller by setting a password or a digital signature. Signing the controller by digital signature is an irreversible process, while the password can be modied or cancelled. The password is applied by default in the c.suite development tool, while the digital signature is an additional function enabled with a dedicated license.

8.1 Protection features

Protection password Digital signature

Purpose To prevent the software being loaded/updated

by unauthorised personnel. To prevent the

software from being cloned. c.pCO signing Reversible Irreversible Generation By c.suite Activation Function included

in standard c.suite

package

Function to be activated with optional additional

license Number of passwors/signatures

c.suite software can be used to generate multiple signatures and/or passwords

Implementation The application is

protected with a password before being uploaded into the c.pCO (see paragraph

6.6 for uploading procedures)

c.pCO is signed by

uploading a digital

signature via USB ash

drive. The application

to be uploaded must be

protected with the same

signature.

Tab. 8.a

8.2 Protection Password

The protection password can be set inside the c.design tool, under "c.pCO Conguration Editor". A protection password can be set for each conguration. The protection password has no eect if using a digital signature.

9. ACCESS MANAGEMENT FOR IP SERVICES

c.pCO controllers integrate a Web Server and a FTP Server:

• Web server: used to access the les (HTML pages, images, JavaScript

code, etc.) stored under the /HTTP/ directory of the public partition in the le system. These pages can show dynamic contents generated by CGI calls (Common Gateway Interface), managed by the controller rmware in order to read/write variables of the application and create logs and custom dynamic pages. These pages are accessed in a LAN by using a browser, entering the c.pCO controller IP address or hostname;

• FTP server: used to access the public partition in the le system, to

read, edit, create and delete les and directories, including web pages. FTP can also be used to transfer a .ap1 le, for example, to update the image of the operating system or the application program. The les are accessed using an FTP client, such as “FileZilla”.

For protecting the contents of the public le system against unauthorised access, the system administrator can create dierent users, and assign each user dierent access proles, dierentiated for each service and adapted to the individual directory.

Access conguration is performed in two steps

1. create users in c.design;

2. create authorisation les in the directories of the public le system that need to be protected.

9.1 Accounts management

c.pCO does not have any account congured by default, consequently the entire public le system has read/write access to the default user (“anonymous”) and web access without authentication. This simplies the operations for rst installation of the application program and web pages via FTP/HTTP protocol. Subsequently, accounts can be created so as to restrict access to the public le system. The accounts who can access the IP services are created in c.design. Open c.design and access the conguration editor.

Fig. 9.a

Click “c.pCO Cong. Editor”: the user conguration page will be shown. Enter the user name and password and conrm by clicking “Add user” for each new user.

Fig. 9.b

Example: the following three users have been created:

User name Password

dave davepasswd bryan bryanpasswd ron ronpasswd

Select the directory where the application program les are located and click “Upload” to load these accounts into the c.pCO controller.

Note:

• max number of users: 5;

• max number of characters in the user name: 15;

• max number of characters in the password: 15;

• in addition to the users saved in the database, the FTP server retains

the default user, called “anonymous”. This special user allows public access to certain directories and to new c.pCO controllers without any users congured. The anonymous user does not require authentication (any password can be entered) and access will be restricted to the directories that have no authorisation les (ftaccess, as illustrated below).

The authorisation les contain a list of users who can access the current directory. Only the users listed in the authorisation le can access the corresponding directory.

Note: an authorisation le only prevents access to the les in the directory where this is located, and not the les in any sub-directories. To disable access to the various sub-directories, the authorisation le needs to be copied to each of these.

The authorisation le is a simple text le, called:

• “htaccess”, when it authorises users of web server services;

• “ftaccess”, when it authorises users of FTP server services.

Authorisation le structure

The authorisation le contains a list of user names who are authorised to access the directory in question, one on each line. There is no extension (e.g. ".txt”).

Example: the authorisation le for the three users created previously will have the following layout, and be called “ftaccess” or “htaccess”.

ftaccess/htaccess

dave

bryan

ron

Whenever a user needs to access a le (web) or directory (FTP), the following procedure is applied to grant/deny access:

1. verify whether the authorisation le (htaccess or ftaccess) exists in the

requested directory. If no le exists, access is granted;

2. if the le exists, this is opened and read sequentially to check whether the

user making the request is included in the list; if not, access is denied;

3. if the user is included in the authorisation le, the system looks up the

user name in the user database. If not found, access is denied;

4. if the user is known, authentication by password is required; if the

password is correct, access is granted.

9.2 Computer - c.pCO connection

There are two ways to connect the c.pCO controller to a computer via Ethernet:

1. computer-c.pCO direct connection;

2. network LAN connection with DHCP server

Computer-c.pCO direct connection

Connect one end of the network cable to the Ethernet port on the computer and the other end to a any of the Ethernet ports on the c.pCO; LEDs blinking indicate correct connection. The Ethernet ports on the c.pCO are auto-crossing (Auto MDI-X), therefore no crossover cable is needed. After connection through Ethernet cable, computer and controller IP addresses must be properly congure in order to belong to the same IP subnetwork.

Conguration example:

Computer:

IP address: 192.168.0.2 Subnet mask: 255.255.255.0

c.pCO controller:

1. press Alarm and Enter together for 3 seconds to access the system

menu;

2. Select Settings -->TCP/IP settings: DHCP = OFF and enter an address

in the same subnet set on the PC, for example: IP: 192.168.0.1 MASK: 255.255.255.0

3. Select update conguration --> Yes

INFORMATION SETTINGS APPLICATION UPGRADE LOGGER

DHCP: Off IP: 192. 168. 0. 1 MASK: 255. 255. 255. 0 GW: 0. 0. 0. 0 DNS: 0. 0. 0. 0 NAME: Update config? Yes

Network LAN connection with DHCP server

Before connecting the c.pCO controller to the LAN, access the system menu and verify that DHCP: On (default setting).

Then connect the c.pCO to the LAN. The IP address is automatically assigned to the c.pCO by the DHCP server, and it can be displayed in the system screens (Settings -->TCP/IP settings).

9.3 FTP connection with authentication

Once having connected the computer to the c.pCO via Ethernet, FTP protocol can be used to transfer les. The program used in this example is “FileZilla”, downloadable for free from the Internet. Proceed as follows:

1. open FileZilla: the following screen will be shown;

2. enter the IP address (or hostname) of the c.pCO controller, the user

name --> anonymous and password -->“empty” and select “Quick Connect”;

3. the user can access all the directories highlighted, as these do not

contain the “ftaccess” le: UPGRADE, HTTP. Access is also available to the HTTP directory and its sub-directories.

Nota: Please use following settings in Filezilla:

• Edit->Settings->Connection-> set timeout in seconds = 0

• Edit -> Settings -> Transfers -> set maximum simultaneous transfers to 1

Fig. 9.d

ENG

c.pCO sistema +0300057EN rel. 1.2 - 29.05.2017

Access to the dierent directories can be restricted, assigning dierent user lists (see paragraph 9.1).

Important: in the event of errors when copying the authorisation les and consequently denial of access, the authorisation les can only be deleted by direct connection to the USB device port.

9.4 HTTP connection with authentication

This paragraph shows how to restrict access to the web interface or part of it. In the example, a website is created with several pages in “\ HTTP”, administration pages in “\HTTP\admin” and user pages in “\HTTP\ user”. Only “dave” and “ron” can access the administration pages, while the user pages are only accessible to “bryan”. All three users can see the common pages in “\HTTP”. The authorisation les shown in the table need to be created and copied by FTP to the corresponding directories (see paragraph 9.1):

No. Authorisation le In directory User Password 1 htaccess HTTP dave davepasswd

bryan bryanpasswd ron ronpasswd

2 htaccess HTTP\admin dave davepasswd

ron ronpasswd

3 htaccess HTTP\user bryan bryanpasswd

Accessing an address of the c.pCO Web Server by using a web browser, then a pop-up window will be shown prompting for the user name and password.

Fig. 9.e

If the user name/password are recognised and the user has been authorised to access the directory, for example “dave”, the web server grants access to the pages, and these can be displayed by the browser.

10. WEB SERVER AND TERA CLOUD PLATFORM

c.pCO controllers family features an integrated web server that can be completely customised by the user. The c.pCO web server can support HTML and JavaScript standards. Custom web pages can be copied in the public le system, in the /HTTP/directory. c.pCO implements some CGI (Common Gateway Interface) scripts that allow to dynamically read and write application variables in order to create dynamic content. A freely customisable package called “Web kit” is available to simplify the creation of custom webpages for the c.pCO. The Web kit comprises sample HTML pages and JavaScript libraries for managing dynamic CGI, fully exploiting the potential of the c.pCO web server. In particular, the examples provided can be used to:

1. display the contents of the pGD1 on the browser pages (pGDWeb,

see paragrap 10.3)

2. display the list of public variables in the application program, allowing

the values to be read and write;

3. display the network status, with the addresses of the connected

devices;

4. plot data on graphs, both in real time as well as extracted from

logged data.

10.1 Web kit download and installation

The freely customisable web package called “Web kit” can be downloaded in ksa.carel.com. The package must be saved in the c.pCO public le system:

1. unzip the .zip le;

2. copy the contents to the /HTTP/ directory in the c.pCO le system by

using the USB device port or FTP protocol through Ethernet (see picture below).

3. Disconnect Usb cable from USB device port.

Fig. 10.a

4. After copy of the Web kit package into folder /HTTP/, it is possible to

access web pages by using a web browser. It is sucient to connect the c.pCO and the computer in the same local network and write in the browser address bar the c.pCO IP address (see paragraph 9.2).

The web pages are independent from application software loaded into the controller, and they are developed to be customized according to the specic application.

Customisation notes:

• The virtual pGD is a matrix of 132 x 64 elements measuring 3 x 3 pixels;

• The background for the LCD matrix measures 394 x 198 pixels;

• The background colour is black (RGB 0, 0, 0), the colour of the display is

light blue (RGB 106, 188, 231);

• The image of the pGD1 is 870 x 455, the background starts at (x, y =

238, 128) and ends at (x, y = 632, 326);

• The width of the buttons is 27%, the heights are 20%, 19%, 19%, 19%, 23%:

these proportions must be maintained to change the background image.

See the comments in: /pgd/index.htm for further details on customising this page.

10.4 Variables table

The variables table includes the public variables exposed by the application sotware. Names and descriptions are dened in c.suite development enviroment.

ENG

Fig. 10.d

Key 1 Frame: blue = communication, red = no communication 2 Variable refresh time 3 Checkbox to enable in order to write variables

Writing the variables

Procedure:

• enable the writing checking box;

• enter the value in the corresponding eld;

• click Set or “Set all selected variables”.

10.5 Variable trend (logger)

The names of the logs are loaded dynamically by the c.pCO based on the Log editor settings in c.design. This means the drop-down menu for choosing the log to be displayed is populated automatically, without having to modify the web page:

• choose the log to be displayed from the drop-down menu at the top;

• set the display interval, as start and end date/time or using the quick

links on the right, used to load the last ‘N’ days/weeks logged;

• click “Load log data” to load the log and display the corresponding

graph.

The graph can then be adapted using the mouse (or touch, when using a touch screen) to zoom, change the colour of the lines, display the numeric values of the variables at a certain point on the graph, or enable the secondary axis. A screenshot in image format can be saved at any time, or the data exported in CSV format.

Fig. 10.e

Choosing the “Live” tab activates a real time graph of the variables, chosen from the list of public variables.

• Click “Show/Hide variables” to show the variable list (automatically

populated by the c.pCO).

• Choose the variables to be displayed from the list

• Choose the sampling period (expressed in seconds) and the display

interval (expressed in minutes)

• Click “Play” to start acquiring the data

In this case too, the graph can be adapted, even during the acquisition process.

10.6 c.pCO connection to cloud tERA

The c.pCO controllers family can establish a remote secure connection to the Carel cloud server platform called tERA. Every c.pCO with built-in Ethernet interface is natively integrated into tERa cloud platform and can access to linked services. Every c.pCO is uniquely identied by the tERA cloud using its MAC address. It is possible to create a customized private portal according to the customers specications. For further information on tERA services available, contact your local Carel sales network.

Fig. 10.g

c.pCO registration:

Activation and registration procedure and settings of the tERA services are described in the "tERA Quick start Guide" (document +030222141), that can be download from www.carel.com. Following data are requested in order to register a c.pCO in tERA server:

• MAC address of the c.pCO

• c.pCO Hardware unique ID

• tERA password

Above data are reported in the c.pCO System menu at the following path: INFORMATION --> pCO INFORMATION (see gure below).

BT v1.2.000 2014/02/12 OS v1.2.000 2014/02/12 SVN REV 2796 MAC 00-0A-5C-40-03-2B UID 000000000000032B tERA 5E2207C4

(230 Vac or 24 Vac/Vdc). There is functional insulation between the two inputs; there is reinforced insulation between the inputs and the rest of the controller;

• ID1...ID8, ID9 to ID12, ID17, ID18 have functional insulation from the rest of the controller;

• for DC voltage inputs (24 Vdc) either the + or the - can be connected to common terminal;

Warning:

• if the load requires a higher current, use an external SSR. 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.

Power to active probes (VREF)

Programmable output: +5 Vdc ±2% or 12 Vdc ±10%, Imax = 50 mA

Emergency power supply Optional Ultracapacitor module (PCOS00UC20 or EVD0000UC0). If the controller works constantly at temperatures near the upper limit

of 60°C it is recommended to use the external module P/N EVD0000UC0, if possible placed in the coolest point of the panel. Modules

PCOS00UC20 and EVD0000UC0 can be connected to the same controller at the same time, thereby doubling the energy available for

closing the valves. Important: the module only powers the valve driver and not the controller.
