INTRODUCTION

pCO sistema: the CAREL range of programmable controllers. This consists of programmable controllers, user interfaces, gateways and communication and remote management interfaces to offer the HVAC/R market a control system that is powerful, flexible and easy to interface with the more commonly-used building management systems. pCO sistema is very reliable and can be easily customised to differentiate the controller on the manufacturer’s own air-conditioning or refrigeration unit.

1. GENERAL FEATURES

All versions of these controllers use a 16-bit microprocessor and up to 4 Mbytes of memory to ensure high performance in terms of speed and memory space. The pCO sistema controllers also come in different sizes according to the number of inputs and outputs so as to always offer the best cost/performance ratio. Given the increasing demand for integration, the pCO sistema family can communicate using some of the most commonly-used communication serial standards, and with the addition of optional boards can be integrated into the most widely available BMS systems. The pCO* family features the possibility to connect ratiometric sensors, the integration of a Built-In terminal, an upgraded programming key and a serial port for connection to the controlled field devices (valves, I/O expansions, electronic valve drivers…). All these features ensure our controllers a level of excellence in responding to the needs of the HVAC/R market.

1.1 Programmability

The CAREL pCO sistema controllers can be programmed using the EasyTools development system, with the following advantages:

• transfer of the software to different types of CAREL hardware. The applications developed for the pCO can simply and quickly transferred from one hardware

platform to another (and vice-versa), simply adapting only the inputs and the outputs;

• rapid development, at competitive costs, of custom programs;

• reliability guaranteed by the use of standard routines, tested in the field.

The use of EasyTools, moreover, ensures the customer the maximum level of privacy and self-management when developing new programs on their own. The possibility to use the same hardware for different applications allows standardisation, with the clear advantages of being able to feature in-circuit and functional testing and burn-in procedures on all of the products and consequently reach a high level of reliability, both overall and in terms of the individual electronic components. EasyTools: exclusive CAREL development software, easy to use, for the programming, simulation, supervision and definition of pLAN networks using CAREL terminals and pCO programmable controllers.

1.1.1 Applications

ApplicationsApplications

Applications

The programmability of the pCO sistema controllers ensures the absolute flexibility of the applications. The same standard hardware can be used to control:

• chillers and heat pumps;

• roof-top units;

• air-conditioners;

• small / medium air handling units (upon request);

• showcases (upon request and to specifications);

• cold rooms (upon request and to specifications);

• seasoning rooms;

• compressor packs;

• universal circuit-closing switches.

Other types of programs can be developed to specific customer requirements.

1.1.2 Hardware architecture

Hardware architectureHardware architecture

Hardware architecture

The structure of the pCO sistema controllers features:

• the pCO controller

pCO controllerpCO controller

pCO controller, fitted with a 16-bit microprocessor for running the control program, and the set of terminals required for connection to the controlled devices (for example: valves, compressors, fans). The program and the parameters are saved permanently in the flash memory, preventing data loss in the event of power failure (without requiring a backup battery). The pCO can also be connected to pLAN networks made up of a maximum of 32 pCO controllers and terminals. Each board can exchange information without the need for additional hardware (any variable, digital or analogue, according to the application software) at high transmission speeds. The connection to the supervisor/telemaintenance serial line, based on the RS485 standard, is made using the optional serial boards (PCOS004850) and the CAREL communication protocol.

• The terminal

terminalterminal

terminal, also managed by microprocessor, fitted with display, keypad and LEDs to allow the programming of the control parameters (set point, differential band, alarm thresholds) and basic functions by the user (ON/OFF, display of the controlled values, optional printing). The terminal does not have to be connected to the pCO for normal operation, but can be used for the initial programming of the fundamental parameters.

The power of the application software means that the user terminal allows:

• the initial programming of the unit, with password-protected access;

• the possibility to modify, at any time, the fundamental operating parameters, optionally protected by password;

• the display and audible signalling (by buzzer) of any alarms;

• the display of the active functions, using the LEDs;

• the display of all the values measured.

Insulation distance

The relay outputs have different features depending on the model of pCO3. The outputs can be divided into groups. There is double insulation between the groups (cells in the table) and consequently these may have different voltages. There is also double insulation between each terminal of the digital outputs and the rest of the controller. The relays belonging to the same group (individual cells in the table) have basic insulation and therefore must have the same power supply (24 Vac or 230 Vac).

There is also double insulation between each terminal of the digital outputs and the rest of the controller. The relays belonging to the same group (individual cells in the table) have basic insulation and therefore must have the same power supply (24 Vac or 230 Vac).

On the pCOC, unlike the pCOB, the 0/1 Vdc signal is limited to the restricted 0-1 V range and therefore is not always compatible with the standard 10 mV/°C signal of the Carel probes (for temperatures below 0°C and above 100°C, a probe alarm may be generated). For the temperature signals, use 4/20 mA or NTC. This is also true for the pCO3, pCO1 and pCOxs.

Insulation distance

The relay outputs have different features depending on the model of PCOC. The outputs can be divided into groups. There is double insulation between the groups (cells in the table) and consequently these may have different voltages. There is also double insulation between each terminal of the digital outputs and the rest of the controller. The relays belonging to the same group (individual cells in the table) have basic insulation and can therefore have the same power supply (24 Vac or 230 Vac).

3.1.9 Connecting the user terminal to the pCO

Connecting the user terminal to the pCOConnecting the user terminal to the pCO

Connecting the user terminal to the pCO

The typical connection between the pGD terminal and the pCO is made using a 6-wire telephone cable supplied by Carel (code S90CONN00*). To make the connection simply plug the cable into the 6-pin connector on the pCO (J10 for pCO3 and pCO1, J5 for pCOXS, J19 pCOC), so that it clicks into place. To remove the connector, lightly press the plastic tab and pull out the cable. The telephone connector provides both the data link and the power supply to the terminal, and is the simplest connection method; in more complex configurations, where more than one terminal is connected to the pCO or to cover lengths in excess of 50 m, a twistedpair cable with shield is required (see the diagrams in chap. 5).

Shielded cable must also be used if the pCO is installed in domestic or similar environments, and consequently subject to the requirements of IEC EN 55014-1 of 04/98) – (see paragraph 5.7). When developing a pLAN network of pCO controllers and terminals, always remember that a pCO can only supply power to one pGD0/1 or old pCOT/I terminal. If it is necessary to manage more than one terminal or the pGD2/3 versions, an independent power supply is required (see the diagrams in chap. 5). The DC voltage at Vterm (J24 for pCO

3

, J9 for pCO1) can supply an ARIA or PLD terminal with a maximum power input of 2 W. The pCO can operate perfectly without the terminal

connected.

Environmental conditions Avoid assembling the pCO and the terminal in environments with the following situations:

 temperature and humidity that do not conform to the rated operating data of the product;  strong vibrations or knocks;  exposure to aggressive and polluting atmospheres (e.g.: sulphur and ammonia fumes, saline mist, smoke) so as to avoid corrosion and/or oxidation;  strong magnetic and/or radio frequency interference (there avoid installing the units near transmitting antennae);  exposure of the pCO to direct sunlight and to the elements in general;  large and rapid fluctuations in the room temperature;  environments containing explosives or mixes of flammable gases;  exposure to dust (formation of corrosive patina with possible oxidation and reduction of insulation).

Positioning the instrument inside the panel

Positioning the instrument inside the panelPositioning the instrument inside the panel

Positioning the instrument inside the panel The instrument must be positioned inside the electrical cabinet so as to guarantee sufficient physical separation of the instrument from the power components (solenoids, contactors, actuators, inverters, ...) and the cables connected to these. Proximity to such devices may cause random malfunctions that are not immediately evident. The panel must feature good ventilation for cooling.

4.1.2 Wiring procedure

Wiring procedureWiring procedure

Wiring procedure

When laying the wires, "physically" separate the power from the control section. The proximity of the wiring of these two sections will, in most cases, cause problems of induced disturbance or, over time, malfunctions or damage to the components. The ideal condition involves running the two

circuits in two separate cabinets. Sometimes, however, this is not possible, and consequently the power section and the control section need to be placed in two separate areas inside the same panel. For the control signals, use shielded cables with twisted wires. If the control cables need to cross over the power cables, the point of crossing should have angles of intersection as near as possible to 90 degrees; never run the control cables parallel to the power cables. CAREL suggests to pay attention to the following wornings:

• Use cable ends suitable for the corresponding terminals. Loosen each screw and insert the cable ends, then tighten the screws. When the operation is

completed, slightly tug the cables to check they are sufficiently tight;

• separate as much as possible the probe and digital input signal cables from the cables carrying inductive loads and power cables to avoid possible

electromagnetic disturbance. Never insert power cables (including the electrical cables) and probe signal cables in the same conduits. Do not install the probe cables in the immediate vicinity of power devices (contactors, circuit breakers or similar);

• reduce the path of the probe cables as much as possible, and avoid spiral paths that enclose power devices;

• avoid touching or nearly touching the electronic components fitted on the boards, so as to avoid electrostatic discharges (extremely dangerous) from the

operator to the components.

• if the power transformer secondary is earthed, check that the earth wire corresponds to the wire that runs to the controller and enters terminal G0; this

must be followed for all devices connected to the pCO;

• when fastening the cables to the terminals, do not push the screwdriver with excessive force, so as to avoid damaging the pCO;

• for applications subject to considerable vibrations (1.5 mm pk-pk 10/55 Hz), secure the cables connected to the pCO around 3 cm from the connectors

using clamps;

• if the product is installed in industrial environments (application of the EN 61000-6-2 standard), the length of the connections must be less than 30m;

• all the very low voltage connections (analogue and digital inputs at 24 Vac/24Vdc, analogue outputs, serial bus connections, power) must have reinforced or

double insulation from the mains;

• in residential environments, the connection cable between the pCO and the terminal must be shielded.

• there is no limit to the number of wires that can be connected to an individual terminal. The only limit concerns the maximum current running through

the terminal: this must not exceed 8 A;

• the maximum cross-section of the wires connected to the terminals is 2.5 mm2 (12 AWG);

• the maximum value of the twisting moment (or torque) for tightening the screws on the terminal (tightening torque) is 0.6 Nm.

Anchoring the pCO

The pCO should be installed on a DIN rail. To secure the controller to the DIN rail, simply rest the device on the rail and press lightly. The rear tabs click into place to fasten the device to the rail. To remove the device, use a screwdriver as a lever in the corresponding opening to lift the locking tabs. The tabs are held in the locked position by return springs.

The pCO can be connected to all CAREL AS*2 series active temperature and humidity probes configured with 0 to 1 V or 4 to 20 mA signals. For the temperature probes, use the 4 to 20 mA or NTC configuration, as the 0/1 Vdc signal is limited to the restricted 0-1 V range and therefore is not always compatible with the standard 10 mV/°C signal of the CAREL probes (for temperatures below 0°C and above 100°C, a probe alarm may be generated). The inputs must be configured for 0 to 1 V or 4 to 20 mA signals by the application program resident in flash memory. The connection diagram is shown below:

4.4 Connecting the digital inputs

The pCO features digital inputs for connection to safety devices, alarms, device status indictors and remote control signals. These inputs are all optically-isolated from the other terminals and can operate at 24 Vac, 24 Vdc and some at 230 Vac. Note:

Note: Note:

Note: separate as much as possible the probe and digital input signal cables from the cables carrying inductive loads and power cables to avoid possible electromagnetic disturbance.

IMPORTANT WARNINGS:

IMPORTANT WARNINGS: IMPORTANT WARNINGS:

IMPORTANT WARNINGS: if the control voltage is taken in parallel from a battery, install a dedicated RC filter in parallel with the battery (the typical features are 100

Ω, 0.5 µF, 630 V).

If connecting the digital inputs to safety systems (alarms), remember that

remember thatremember that

remember that: voltage across the contact must be considered as the normal operating condition, while no

voltage must represent an alarm situation. In this way, any interruption (or disconnection) of the input will also be signalled. Do not connect the neutral to an open

digital input. Always make sure that it is the line that is disconnected. The 24 Vac/Vdc digital inputs have a resistance of around 5 kΩ.

To maintain the optical isolation of the digital inputs, a separate power supply must be used just for the digital inputs; Figs. 4.h and 4.i show the connection diagrams for the versions: MEDIUM (extended) and LARGE (limited to the part regarding the terminals located inside, on the board). While being the more common and the simplest diagrams to complete, these do not exclude the possibility of powering the digital inputs independently from the power supply to the pCO. In any case, the inputs only have functional insulation from the rest of the controller.

ONLY There are up to two groups of 230 Vac inputs. Each group features two inputs and the groups have double insulation between them and therefore may have different reference voltages. The digital inputs cannot be independent within each group: for example, with reference to Fig. 4.m, inputs ID15 and ID16, due to the common terminal, must be powered at the same voltage to avoid dangerous short-circuits and/or 230 Vac being supplied to circuits operating at lower voltages. In any case the inputs have double insulation from the rest of the controller. The following figure represents one of the most common diagrams for connecting the 230 Vac digital inputs.

The uncertainty of the switching threshold ranges from 43 to 90 Vac. It is recommended to use a 100 mA fuse in series with the digital inputs.

The relays are divided into groups, according to the insulation distance. Inside each group, the relays have just basic insulation and thus must have the same voltage (generally 24Vac or 110-230Vac). Between the groups, instead, there is double insulation and thus the groups can have different voltages. In any case there is double insulation from the rest of the controller.

5. CONFIGURATION OF THE PLAN NETWORK

5.1 Introduction

All the pCO controllers can be connected together and to other Carel devices in a local network (pLAN), without requiring optional devices, thus allowing the communication of data and information from one location (node) to another. The pCO terminals can display the variables (temperature, humidity, pressure, I/O, alarms) from one controller only at any one time. The terminal does not need to be connected to the pCO for the normal operation of the controller, however it can be used for the initial programming of the fundamental parameters. If one or more terminals are disconnected or malfunctioning, the control program continues to operate correctly on each pCO board. In general, the application program can monitor the status of the network and the terminals and respond in the event of malfunctions. The figure below shows a possible pLAN network connection diagram.

Fig. 5.a

The standard communication speed over the network is 62500 bps but some devices also support speeds of 115200 bps. All the units in the network must in any case use the same speed. A maximum of 32 units can be connected, including:

- pCO controllers, running the control program;

- boards that extend the I/O functions (such as the EVD200 driver);

- terminals (LED, 4x20 LCD and graphic).

Each unit in the pLAN is identified by a unique address, that is, a number between 1 and 32. Address 32 can only be assigned to a terminal. The programs for the different applications (e.g.: standard chiller, standard air-conditioners, compressor racks, ...) cannot be automatically integrated into a local network: they must be configured considering the architecture of the system and using the developing CAREL tool. Each pCO board connected to the network can manage up to 3 pLAN terminals at the same time. The values are displayed simultaneously and not independently on each terminal, as if they were connected in parallel: for this reason, the pCO cannot control different types of terminals at the same time (for example, one pGD

1

and

one pGD3).

A terminal associated with a certain board is defined as:

- private (“Pr

PrPr

Pr”) if it exclusively displays the output of that board;

- shared (“Sh

ShSh

Sh”) if either automatically or from the keypad it can be switched between more than one board;

- shared with printer (“Sp

SpSp

Sp”) if, as well as being shared, it is fitted with a RS232 serial board for connecting a printer (only for the old PCOT and PCOI terminals, not the

pGD).

Each pCO maintains constantly updates the display on the private terminals, while the shared terminals are only updated only if the pCO controller in question has control over the terminal at that moment.

In the example, the shared terminal is associated with 4 pCOC controllers, however currently only controller 1 can display data and receive commands from the keypad.

The terminal is switched between the different controllers cyclically (1→2→3→4→1 …) by pressing a predefined button. Switching can also occur automatically,

managed directly by the program; in this case, in fact, a pCO controller can request control over the shared terminal to display new alarms or, vice-versa, give up control to the next pCO after a preset time (cyclical rotation). The data corresponding to the number and type of terminals are established during the initial configuration of the network, and are saved in the permanent memory on each individual pCO controller. The details of the configuration are described below. The pLAN connection between two pCO controllers can only be made using an AWG20/22 shielded cable, made up of a twisted pair plus the shield. The terminal and the pCO can be connected using a 6-wire telephone cable or AWG20/22 shielded cable, depending on the model of terminal. Further details on the installation of the terminals are provided in the section on “pLAN electrical connections

pLAN electrical connectionspLAN electrical connections

pLAN electrical connections”.

5.2 Installing the pGD0 and pGD1 terminals

The connection between the terminal and the pCO is made using a 6-wire telephone cable, supplied by CAREL (code S90CONN). To make the connection, simply plug the telephone connector into the RJ12 jack on the rear of the terminal, and in connector:

• J19 on the pCO

Selecting this mode has no effect on the management of the printed messages. During operation, the terminal monitors special conditions of the pLAN network, and highlights these with messages on the display, as illustrated below.

• Message “Starting up, please wait to ”: the terminal has just been started and/or is initiating communication.

• Message “Please wait...”: the procedure for assigning the private or shared terminals to a pCO has just ended and the terminal is awaiting the start of

communication.

• Message “No network link: terminal alone”: the pLAN protocol has been selected and no pCO is detected within 40 s from power-up, or alternatively the

network is inactive (no package received) for at least 20 s during normal operation.

• Message “I/O board (at address xx) fault”: the pLAN protocol has been selected and the terminal has lost communication with the pCO whose output it was

displaying for more than least 8 s.

• Message “No I/O board configured for this terminal”: the pLAN protocol has been selected and the terminal is not among those configured for the pCO in the

network. The message is displayed 40 s after power-up or around 8 seconds after ending the procedure for assigning the terminals to a pCO.

5.4 Installing the Aria terminal

The connection between terminal and pCO is made using AWG20/22 shielded cable only. To connect the cable to the terminal, proceed as follows.

1) Disconnect power to the terminal.

2) Separate the front of the terminal from the bottom shell (for further details, see the user manual or the instruction sheet).

3) Fasten one end of the cable shield to the terminals marked “GND”, “Rx/Tx+” and “Rx/Tx-” in the bottom shell.

4) Close the terminal again.

To connect the cable to the pCO, the end not connected to the Aria terminal must be terminated with a 3-pin plug-in connector, then plug this into connector:

• J6 on the pCO

XS

,

• J11 on the pCO

1

, pCOC, pCO3. The Aria terminal communicates with the pCO boards by exchanging variables across pLAN. As the code that manages the terminal is resident in ROM, and therefore cannot be changed depending on the devices that make up the network (as normally occurs for pCO boards), the terminal can receive variables from any device in the network, but can only send data to one device, selected by the user. Overall, there are five parameters used to configure pLAN communication on the Aria terminal:

• L1

L1L1

L1: pLAN address of the Aria terminal (between 1 and 31);

• L2

L2L2

L2: pLAN address of the device the variables are sent to (between 1 and 31);

• L3

L3L3

L3: pLAN page (between 0 and 255);

• L5

L5L5

L5: used to selectively inhibit the reception of some variables;

• L6

L6L6

L6: communication protocol over RS485 line, selectable as pLAN or CAREL Slave.

For further information on the parameters and on the variables that can be exchanged, see to the user manual. The Aria terminal parameters can be set on the keypad or by copying the settings from a hardware key programmed previously using a sample device. In the first case (programming by keypad), proceed as follows:

1) power up the terminal;

2) press the SET and MODE buttons together: the terminal will display a screen for entering the enabling code;

3) using UP or DOWN enter the code “22” and confirm by pressing SET: the terminal enters parameter configuration mode, showing a screen similar to the one

below (the code at the bottom is the name of the parameter, while the number at the top is the value of the parameter).

4) Press the UP and DOWN buttons until the terminal shows the desired parameter.

5) Press SET to make the change: the selected parameter flashes.

6) Enter the desired value using the UP and DOWN buttons, then confirm by pressing SET.

7) Exit programming mode by pressing the HOLD button.

Important:

Important: Important:

Important: after having changed the pLAN address (parameter L1), turn the terminal off and on again for the changes to take effect.

If wanting to set the parameters using a hardware key, first of all copy the parameters from the sample device as follows:

1) connect the key;

2) power up the sample device by pressing and holding SET and DOWN;

3) the device starts copying the data to the key: the display shows the message “EC”;

4) at the end of the copy operation the message OK or NO is shown, depending on the outcome of the data transfer.

To then copy the parameters from the removable hardware key to the terminal, simply proceed as follows:

1) connect the key;

2) power up the terminal by pressing and holding the UP button;

3) the terminal starts copying the data from the key: the display shows the message “CE”;

4) at the end of the copy operation the message OK or NO is shown, depending on the outcome of the data transfer.

5.5 Setting the pLAN address on the pCO

1

, pCOXS, pCOC and pCO3

The pCO1, pCOXS, pCOC and pCO3 controllers do not have dipswitches for setting the pLAN network address: the pLAN address can set from any terminal, pGD0, pGD1, pGD2, pGD3 or built-in on the models where fitted. To set the address from an external terminal (not built-in), proceed as follows.

1) Set address 0 on the terminal (see the previous sections for details on how to set this address).

2) Power down the pCO.

3) Remove any pLAN connections from the pCO to other controllers.

4) Connect the terminal to the pCO.

5) Power up the pCO, pressing the UP and ALARM buttons together on the terminal. After a few seconds, the pCO commences the start-up sequence, and the

display shows a screen similar to the one below:

#################### selftest please wait... ####################

Fig. 5.n

Fig. 5.nFig. 5.n

Fig. 5.n

6) When this screen appears, wait 10 seconds and then release the buttons.

7) The pCO stops the start-up sequence and shows a configuration screen similar to the one below:

pLan address: 0 UP: increase DOWN: decrease ENTER: save & exit

Fig. 5.o

Fig. 5.oFig. 5.o

Fig. 5.o

1) Then set the pLAN address using the UP and DOWN buttons on the terminal.

8) Confirm the address by pressing the ENTER button: the pCO completes the start-up sequence and uses the specified address.

Note:

Note:Note:

Note: step 6) is only required for the pGD2 or pGD3 terminals. To modify the address from a Built-In terminal, steps 1) and 3) are not needed; the rest of the procedure is the same as described above.

5.6 pLAN electrical connections between the pCO controllers

6. OPTIONS AND EXTERNAL MODULES

CAREL has always offered its customers different to interface the pCO sistema controllers with the more commonly-used BMS (Building Management Systems).. Today in fact, with the expansion of BMS, the issue of communication between controllers made by different companies is increasingly important. CAREL has consequently developed compatibility with all the protocols that are emerging as the standards in HVAC/R and intelligent management systems, such as Modbus®, LonWorks®, BACnet™, SNMP. As regards communication between controllers made by different companies, CAREL offers an excellent variety of solutions that allow the pCO family controllers to interface with controlled field devices, such as valves, VFD, serial sensors, Belimo actuators etc. In this way, the pCO controller does not just manage the single unit, but the entire air-conditioning / refrigeration system.

IMPORTANT WARNINGS

IMPORTANT WARNINGSIM PORTANT WARNING S

IMPORTANT WARNINGS: operator safety and precautions to be observed when handling the board/boards. To safeguard operators and the boards, disconnect power before performing any operations. Electrical damage may occur to the electronic components as a result of electrostatic discharges from the operator. Suitable precautions must be therefore be taken when handling these components. Specifically:

• before using any electronic component or board, touch an earthed object (simply not touching the board does not

prevent discharges, as static electricity can produce a 10000V spike, which can form an arc of about 1cm);

• all components must be kept inside their original package as long as possible. If necessary, take the board from its

package and place it into an antistatic bag, without touching the back of the board;

• absolutely avoid using non-antistatic plastic bags, polystyrene or sponge, and avoid passing the board directly to other

operators (to prevent electrostatic induction and consequent discharges).

Interface for the OEM series humidifiers (PCOUMI2000)Interface for the OEM series humidifiers (PCOUMI2000)

Interface for the OEM series humidifiers (PCOUMI2000) The PCOUMI2000 module is an interface for the pCO electronic controllers. This allows the control of the fundamental parameters of the OEM humidifiers manufactured by CAREL (level and conductivity of the water in the cylinder, TAM sensor for current input) directly from the pCO electronic microprocessor controller. The values measured by the sensors are converted into signals that can be read by the inputs on the pCO (for more information refer to the user manual for the application program). The PCOUMI2000 interface differs from the PCOUMID000 interface due to:

- greater precision and immunity to disturbance both as regards the conductivity reading and the level sensor;

- the “high water level” signal can be managed either as a digital or analogue output.

Consequently, the controller can be connected to both the PCOUMID000 and the PCOUMI2000 board, with the only difference being the setting of the corresponding parameter, so as to tell the software to use the correct conductivity curve.

for electronic expansion valves (EVD*400)for electronic expansion valves (EVD*400)

for electronic expansion valves (EVD*400) The EVD0000400 module for electronic expansion valves with two-pole stepper motor is a controller that manages the expansion of the refrigerant in a refrigerant circuit. This function is achieved by optimising the opening of the valve using a PID algorithm and some special auxiliary control routines. The driver has a tLAN interface for connection to a Master unit, an RS485 adapter (featured in models *410, *411, *420 and *421) that allows connection to units with the supervisor protocol, from 4800 to 19200 baud, or with the pLAN protocol. The driver automatically recognises the protocol and the baud rate. Alternatively, the driver can operate in stand-alone mode. As well as the serial connection, in any configuration described above, the driver can be accessed for configuration or monitoring via an auxiliary “service” serial port at 4800 baud with supervisor/tLAN protocol and network address = 1 (fixed). The USB converter CVSTDUTTL0 is required to use the “service” serial port. This connection is for temporary use. If using the “service” serial port or the supervisor protocol on the main serial port, the EVD4UI program is available; this has a user-friendly graphic interface and is available on the KSA site.

Phase control module

Phase control modulePhase control module

Phase control module The controller works with two-pole stepper motors. It operates with a theoretical sinusoidal waveform, in micro-steps and with speeds from 5 to 1000 steps; the current and the control speed effectively achievable depend on the resistance and the inductance of the motor windings used. If the driver is connected to a pCO, it receives all the individual operating parameters for the motor from the pCO controller. The controller can manage motors with maximum positions of up to 32000 steps. For connection use 4-wire shielded cables, AWG18/22, max. length 9.5 m. The shield should be connected to the closest possible earth point in the panel. For the technical specifications and the meanings of the connections (pins), as well as details on the procedure for fitting the board, follow the instructions shown on the instruction sheet provided in the packaging (code +050003875).

• Winload;

• SmartKey.

7.1 WINLOAD

WINLOADWINLOAD

WINLOAD

In all CAREL 16-bit pCO sistema controllers the resident software can be updated from a PC. To do this, CAREL provides the WinLoad32.exe program and an RS485 serial converter for the pCO. The special driver needs to be installed on the PC, again supplied by CAREL. WinLoad32.exe is included in the installation of the “Easy Tools” program suite, inside the pCO Manager program or alternatively is available separately at the site http://ksa.carel.com in the “download : support : software utilities” section. The installation includes, as well as WinLoad32.exe, the user manual and the driver for the RS232-485 converter. The pCO controller can be connected directly to the PC via the RS485 serial port used for the “pLAN” connection, or alternatively via the optional BMS serial port used for the “supervisor” connection, with the RS485 serial board. The BMS serial port and the optional RS232 serial port can be used to connect the pCO to an analogue (PSTN) or GSM modem and consequently establish a remote connection to WinLoad32. Winload can communicate with all the pCO family programmable controllers. The program is used in general to update and download to the PC the BOOT, BIOS, application, configuration files and logs, and in special cases, such as with the pCO

3

, also save files to the new NAND flash.

It should be stressed that updating the BOOT is generally NOT RECOMMENDED by Carel; Carel always loads the BOOT required for the correct operation of the unit directly during production. Only in very special cases will Carel ask the user to update the BOOT. The BIOS can only be loaded using the pLAN serial connection. Updating the BIOS changes the unit operating mode to low level. In this mode, the data logs cannot be downloaded to the PC nor the application loaded in compressed format. To restore the unit to normal communication mode with Winload, reset the pCO after having successfully loaded the BIOS. Winload is configured automatically for the unit connected, for example, certain versions of Bios can be loaded or are inhibited, the log configuration may or may not be available for download, the possibility of the unit to use the expanded RAM is recognised and therefore an application that uses all the RAM available may or may not be loaded. In special cases, nonetheless, certain options need to be set, for example, the baud rate if the pCO is a pCO with 14.7 MHz or 16 MHz quartz, using the command line of a normal Windows connection with the Winload32.exe executable. The on-line help and the “CHANGELOG” register file in any case provide help to the user. In general, the sequence of operations for establishing communication between Winload in graphic mode and pCO is as follows:

• connect the serial converter or USB to the PC and to the pCO;

• open the Winload program on the PC, by double clicking the icon after having activated any options by command line;

• on the main screen, set the serial port on the PC that the serial converter is connected to and the pLAN address of the pCO in question;

• power up the pCO;

• wait for the controller to come online, as indicated at the bottom left of the main screen;

• then select the desired directory on the main page to perform the desired operation.

For “EASYWINLOAD” mode, used for automatic loading with the settings made before running the program, and for the remote connection via MODEM, see the online help in the Winload program. The download options are listed in the tables below:

7.1.1 Commissioning Tool

Commissioning ToolCommissioning Tool

Commissioning Tool

Settings required to use the Commissioning Tool Settings on the pCO for using the Commissioning Tool:

1) the application must feature a screen used to set the Winload protocol on the serial port where the PC with the Commissioning Tool is connected.

Otherwise, there must be another possible procedure for selecting the protocol (e.g. from supervisor).

2) In the remote connection correctly set the system variables relating to the PSTN or GSM modem.

3) To run the operations made available with the commissioning tool, connect when the application is already running; this means that procedures must be

available for setting in advance (screen in the application or supervisor) the Winload protocol after that the pCO has been powered up. If the pCO is directly connected via pLAN serial on power-up, it enters Winload mode and the operations relating to the commissioning tool cannot be managed.

4) If the firmware and the application are updated, the pCO must be reset before being able to use the Commissioning Tool.

5) Once the protocol has been set correctly on the desired serial port, the PC can be connected. IMPORTANT: if using the BMS or FIELDBUS serial port, once

the pCO is disconnected by command from the PC (for example, when switching from the PCOLOAD window to the Commissioning Tool window and vice-versa) the pCO restores the protocol that was previously set on the serial port in question. If the application was previously updated, on the other hand, the pCO is automatically reset. To reconnect the pCO in these cases, restore the Winload protocol on the pCO.

Memory limits:

Memory limits:Memory limits:

Memory limits: The periodical monitoring of the variables in the application is limited to a maximum of 250 WORDS, which can be defined as desired from the entire memory available to the application. The application variable virtualisation function is limited to a maximum of 50 WORDS, which can be defined as desired from the entire memory available to the application. There are no address setting limits to writing and reading the individual “one-shot” variables: all the memory addresses reserved for the application are available, in all types of memory on the pCO: X memory, T memory, P memory, E memory.

7.2 Smart Key

The new SMARTKEY programming key is used to emulate the operation of the parallel programming key on the models of pCO where this is not available (pCOXS, pCO3), with the exception of the BOOT, which is not loaded by the SMARTKEY. Specifically, the key can clone the contents of a pCO and then download these to another identical pCO using the telephone connector on the terminals (the pLAN must be disconnected). This function is obviously available for all the pCO controllers, even those with the parallel key. As well as this mode, the key can also copy the logged data from a series of pCO controllers and then copy the data to a PC. Using a PC running the “SMARTKEY PROGRAMMER”, the key can be configured to run certain operations: copy logs, program applications, program the Bios, etc. For further details, see the online help in the “SMARTKEY PROGRAMMER” and the SMARTKEY instruction sheet.

This type of memory is only available on the pCO3 versions with codes pCO3 * * * C/D/F/G/H/I * *. Using Winload version 3.37 and the new pCOLOAD routine in the pCOMANAGER program, any type of file can be loaded into the NAND FLASH memory, for example, source files of the application on the unit. As well as this function, the IUP, BLB (or BIN) and DEV files, representing the files of parameters, the screens to be displayed in the various languages and the control logic, can also be loaded to the NAND flash and then selected from a screen on the terminal to be used as the current application on the pCO. This means that multiple applications, or multiple languages, or alternatively multiple parameter files can be loaded to the NAND flash memory and then the desired application, language or set of parameters can be selected and loaded to main flash memory. The files in NAND flash memory can be selected for copying the main flash from a screen managed directly by the Bios. The procedure is described in the following paragraph.

Limits:

Limits:Limits:

Limits:

• Currently (Bios 4.01) the number of files that can be saved to NAND flash memory is limited to 40.

• The NAND flash memory can only be updated using the local Winload connection and via pLAN serial.

• The maximum overall capacity of the memory is in any case limited to 32 Mbytes.

7.4 Checking the software installed on the pCO and other information

The current program version can be checked at any time (CRC code expressed in hexadecimal format), as well as whether this is run from the key or resident. To do this, simply proceed as described below.

Each of the four rows displayed accesses further screens, managed by BIOS and therefore always present, regardless of the application loaded. To access the functions relating to a row, simply select the row by moving the cursor “<” using the UP and DOWN buttons, and then confirm by pressing the ENTER button. To exit the screen press the MENU or Esc button on the terminal, or wait around 40 seconds. The screens provide various types of information.

1. SYSTEM INFORMATION

SYSTEM INFORMATIONSYSTEM INFORMATION

SYSTEM INFORMATION:::: selecting this function displays information on the software loaded and on the size of the RAM and Flash installed. The screen displayed is similar to the one below.

B O O T V 4 . 0 0 1 0 / 0 1 / 0 6

B I O S V 4 . 0 0 0 3 / 0 2 / 0 6

> 2 + 2 M B <

A P P . C R C : 3 3 5 D 2 M B

The first row displays the BOOT version and date. In the example shown in the figure, the pCO is working with BOOT 4.00 of 10 January 2006. The second row displays the BIOS version and date. In the example shown in the figure, the pCO is working with BIOS 4.00 of 3 February 2006. The third row indicates the size of the Flash on board and, on the pCO1 and pCO2, also the size of the Flash in the parallel key or on the expansion board, if featured. The “>” and “<”characters indicate the starting Flash used by the pCO: to the left if the pCO starts from the Flash on board, to the right if the pCO starts from the key. In the example, the pCO is running the BOOT, BIOS and application loaded on the board, and there is no key nor memory expansion. The fourth row displays the CRC of the application and the amount of Flash it occupied. In the example, the CRC of the application is 335D and it requires 2 MB of memory to run. If this row shows 1 MB, a pCO with 1 MB Flash can run the program. The CRC is a number that summarises the application loaded in the flash memory on the pCO, as well as some other system information. Consequently, the version of the application can be recognised using the corresponding screen.

2. LOG DATA

4. NAND FLASH FILES

NAND FLASH FILESNAND FLASH FILES

NAND FLASH FILES:::: this row is only displayed on the pCO3 boards that have additional NAND flash memory. Selecting this function displays the names of the IUP, BLB, GRP and DEV files saved in the NAND memory; an application can also be copied from the NAND memory to the main flash memory on the pCO. Each file name is shown on a screen similar to the one below.

[ X ]

P G D 2 3 _ A L L . g r p

To move from one file to the next simply press the UP and DOWN buttons. Press the ENTER button to select the current file and copy it to the main flash memory. The files selected for the copy operation are marked by an “X” on the first row of their screen; in the example shown in the figure, the file called “PGD23_ALL.grp” is selected to be copies. To start the copy procedure, press the UP or DOWN button until reaching the following screen:

P r e s s E n t e r

t o s t a r t c o p y i n g

and then confirm by pressing ENTER. For further information on the use of the NAND memory, see the WinLoad manual.

To exit these two screens, press the Menu button on the local terminal or wait around 40 seconds.

Check:

1. the correct power supply to the pCO;

2. the correct power supply to the probes: if the voltage (+Vdc>20V) is near zero, disconnect the probe and measure the power supplied by the pCO. If this is

still near zero, turn the controller off and wait a few minutes. If the problem persists, contact CAREL service; otherwise the connection that was removed was short-circuiting the power supply.

3. the separation of the power supply to the digital inputs from the power supply to the pCO. A 24 Vac/24 Vac transformer with a minimum rating of 5 VA can

be used.

4. that the probe wires are connected according to the instructions;

5. that the probe wires are positioned a sufficient distance from possible sources of electromagnetic disturbance (power cable, contactors, cables with high

voltages and running to devices with high peak current);

6. that there is not a high thermal resistance between the sensor and any probe socket that may be used. If necessary, place conductive paste or oil in the

socket to ensure correct transfer of the temperature;

1. the analogue inputs used for the probes are set to accept 4 to 20 mA signals (in the application program);

2. the full scale set via software corresponds to the probes used;

3. the probe capillary is not blocked.

4. Measuring the voltage across terminals Bn and GND gives an indirect indication of the probe signal current, as the input has an impedance of 100Ω,

applying the formula:

I= V/R (2V= 20 mA).

The pressure value “Ps” that the probe is sending can be calculated as follows (FS= Full scale):

Ps= (Vmeas/100 - 0.004) x (FSmax - FSmin) / 0.016 + FSmin Example: the probe used has FSmin= -0.5 bar, FSmax = 7 bar; the voltage read is equal to Vmeas= 1 Vdc.

The pressure Ps that the probe is measuring is equal to: Ps= (1/100 - 0.004) x [7 - (-0.5)] / 0.016 + (-0.5) = 2.3 bars.

The FieldBus serial port features an additional security feature, that is, the calculation of the CRC, to ensure that communication is correct in all circumstances.

CAREL Master protocolCAREL Master protocol

CAREL Master protocol

The CAREL Master protocol can be used to read and write variables from/to peripherals that use the CAREL Slave protocol. This protocol is used to talk to I/O expansions, drivers and fan coil controllers in a simple and economical manner. There are two versions of the CAREL Master protocol: both versions use a list allocated in the application RAM. The second version also uses atoms to simplify the development of the application and make the commands and the reading of the variables by the peripherals faster. Both versions allow the supervision of up to 207 devices and 207 variables per device. The limits depend on the availability of user memory.

• update the BOOT file;

• update the BIOS file;

• download the applications (*.IUP – *.BLB – flash1.BIN - *.DEV files);

• update the files with the rules for acquiring the data log (*.PVT – *.LCT files);

• acquire the logged data;

• acquire the values of the parameters in the buffer memory.

Specifications communication: 1 Start, 8 data, selectable Stop bits (def. 1), selectable parity (def. no) Baud rate: 1200 – 2400 – 4800 – 9600 – 19200 bps; some baud rates may not be supported by all the devices Connectable devices: Max 247 in Unicast mode (devices with address different from 0) Exchangeable variables: Modbus variables: 65533 analogue/integer (“registers”) – 65533 digital (“coils”) Type of cable / max. distance: AWG 20/22 shielded cable / max 1000 m total

The acquisition time for all the variables on a slave device depends on the consecutiveness of the ModBus addresses of the device variables and the management software (application). Typically, at 19200 bps a read command requested by the application is executed by the Bios on the pCO in around 60 to 80 ms regardless of the number of variables read. As the read commands are requested by the application, the acquisition of all the variables on a slave device depends not only on how many there are and whether they are consecutive, but also on the structure of the application.

If the system variable BMS_EXTENSION= 0 207 analogue – 207 integer – 207 digital. If the system variable BMS_EXTENSION= 1 The following operations can be performed across the remote WinLoad connection:

10.12 GSM protocol (GSM modem)

The GSM protocol allows the pCO controllers to automatically connect to a remote CAREL supervisor and be called by a remote CAREL supervisor or by a remote WinLoad application (see note after Tab. 10.p). All the supervision and management operations already described for the PSTN protocol can thus be performed. In addition to these functions, the GSM protocol is used to send and receive SMS messages over the GSM network using the wireless modems that support this function; the SMS messages are sent upon certain events or alarms, according to rules that are established in the application program.

Connectable devices

Connectable devicesConnectable devices

Connectable devices Remote CAREL supervisor or remote WinLoad. To establish the connection to the supervisor or WinLoad, connect the pCO to a GSM modem; recommended models are Wavecom WMOD2B*, FALCOM A2D* or Siemens TC35*.

Specifications

SpecificationsSpecifications

Specifications The following variables can be exchanged across the connection to a remote CAREL supervisor: 127 analogue – 127 integer – 199 digital. If the system variable BMS_EXTENSION= 0 207 analogue – 207 integer – 207 digital. If the system variable BMS_EXTENSION= 1 The following operations can be performed across the remote WinLoad connection:

- update the application files (*.IUP – *.BLB – flash1.BIN - *.DEV);

- update the log files (*.PVT – *.LCT);

- acquire the logged data;

- acquire the parameters in buffer memory.

In addition, SMS messages can be exchange, as follows:

- send the pCO a suitably formatted SMS to set the supervisor variables;

- send, from the pCO, SMS messages in the desired format to signal alarms or any other information specified by the application.

10.13 MP-Bus protocol

The MP-Bus protocol is used to manage the BELIMO series actuators, exchanging variables, writing the configuration parameters and reading the values of any probes connected to the actuators.

10.14 Serial printer protocol

The Serial printer protocol is used to connect the pCO to any printer fitted with an RS232 interface; this allows paper copies to be generated of particularly important information, for example the trend in the temperature in a cold room over time. The information to be printed can be completely configured in the application. Instead of the printer, other devices with RS232 serial interface can be connected, for example a terminal emulator or a PC with a program that saves the data received via the serial link to the hard disk. Available on the following serial ports
