1. INTRODUCTION

The pCO5+ is a microprocessor-based, programmable electronic controller that is fully compatible (hardware and software) with the pCO Sistema family of devices, which includes programmable controllers, user terminals, gateways, communication devices and remote management devices. These devices represent a powerful control system that can be easily interfaced with most Building Management Systems (BMS) available on the market.

The pCO5+ controller has been developed by CAREL to provide solutions to a host of applications in air-conditioning, refrigeration and HVAC/R in general. It is highly ﬂ exible and can be used to make special products on customer speciﬁ cations.

In a pLAN network (pCO Local Area Network) the pCO5+ can be connected to input/output expansion cards (e.g. pCOe), to other pCO5+ controllers, to all the controllers of the pCO Sistema family and to the terminals of the pGD range. Up to 32 devices (controllers and terminals) can be connected together, allowing highly eﬃ cient sharing of information. Each device in the pLAN network can exchange digital or analogue data with all the others, depending on the application program used.

Compared to pCO3 controllers, pCO5+ units are equipped with two extra built-in RS485 serial ports – one for the Fieldbus and one for supervision/ telemaintenance purposes (BMS).

Each Fieldbus serial port, whether built into the controller or installed via an optional card, can be connected to controlled ﬁ 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 ﬁ eld-level, automation-level or management-level standard bus systems, such as Konnex®, LON®, BACnet™, etc.

The Medium range includes controller versions with one or two built-in drivers for electronic expansion valves. The Ultracap module (accessory) can be used as an emergency power supply for valve drivers, and allows shutting the valves completely in case of power failures (alternating current).

Main features

• the same controller can be connected to up to 3 PGD terminals;

• the program and parameters are saved permanently in a non-volatile

memory (ﬂ ash memory), preventing data loss in case of power failures (without requiring a backup battery);

• 32-bit microprocessor controllers with 5 or 9 MB storage capacity

ensure high performance in terms of speed and memory space;

• allows connecting up to 32 devices to pLAN networks consisting

of a series of pCO5+ controllers and terminals. Each controller can exchange data with the other controllers at high speed without requiring additional hardware;

• external or built-in terminal with display and LED-button keypad; can

be used for uploading software and commissioning;

• fast upload/download of controller software using a “Smart Key(*)” or

any pendrive (provided the controller is equipped with the relative port);

• universal inputs/outputs conﬁ gurable via an application program for

connecting active and passive probes, digital inputs, analogue and PWM outputs. This extends the possibilities of conﬁ guring inputs/ outputs without having to install a larger controller;

• allows using the 1Tool software (installable on a personal computer)

for creating and customising application programs, performing simulations, supervising operations and setting up pLAN networks;

• allows uploading application software to the controller using the pCO

Manager program, available free of charge at http://ksa.carel.com;

• many dedicated programs available for controlling a variety of HVAC/R

applications;

• allows developing new application programs according to customer

speciﬁ cations;

• wide range of models distinguished by:

- microprocessor storage capacity: 5 or 9 MB;

- size (Small, Medium, Large, Extralarge), for maximum ﬂ exibility depending on the application;

- solid state relay (SSR) digital outputs (24/230 V);

- NO or NC relay outputs;

- USB ports;

- optically-isolated/non-optically-isolated built-in serial ports;

- built-in display.

• various kinds of connectors (spring, screw, etc.).

(*) function available from Smart Key ﬁ rmware version 4.0.

Main features of terminal

Thanks to the capabilities of the application software, while the unit is normally working the user terminal can be used to:

• edit the main parameters;

• receive acoustic alerts (from buzzer) and visual alerts (on display) of any

alarms triggered;

• view active functions and measured quantities displayed by LED

indicators.

1.1 Programmability

The programmable controllers of the pCO family can be programmed using the 1Tool development software, which oﬀ ers the following advantages:

• transferability of software. Applications developed for the pCO can be

quickly and easily transferred between diﬀ erent hardware platforms by simply modifying the inputs and outputs;

• rapid development of custom programs at competitive costs;

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

and in the ﬁ eld.

In addition, using 1Tool provides customers with maximum conﬁ dentiality and ample self-management when developing new programs on their own. Using the same hardware for diﬀ erent applications enhances standardization, with the clear advantage of being able to perform incircuit, functional and burn-in tests on all products, thereby ensuring a high level of reliability in general and in terms of individual electronic components.

Applications

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

• chillers and heat pumps;

• roof-top units;

• air-conditioners;

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

• refrigerated counters (on request and to speciﬁ cations);

• cold rooms (on request and to speciﬁ cations);

• curing rooms;

• compressor racks;

• universal stage controllers.

pCO5plus +0300020EN rel. 1.2 - 07.11.2013

1.2 Functional layout

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

3. COMMUNICATION PORTS

3.1 Serial ports

Compared to the pCO3, pCO5+ (and pCO5) controllers have a second BMS serial port on connector J25 (BMS2) and a second Fieldbus port on connector J26 (FBus2). pCO5+ Large and Extralarge boards still have connector J23, which is marked FBus2 like connector J26. With reference to management under 1Tool, this is the same serial line, so diﬀ 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 aﬀ ect port J23).

3.3 Controller network connections

The pCO5+ comes with three kinds of serial ports: pLAN, Fieldbus, BMS. The RS485 Fieldbus serial port is designed with Master-type hardware, while the RS485 BMS serial port has Slave-type hardware. The protocols used on the RS485 Fieldbus port are, due to the nature of the port, Master protocols (CAREL Master or Modbus RTU Master), although in special cases Slave protocols can be used (CAREL Slave or Modbus RTU Slave), adopting the necessary measures. Likewise, Slave protocols are applied on the RS485 BMS port, although under certain conditions Master protocols can also be used.

Note: The pLAN network is multi-master, meaning that each

controller can work as Master or Slave at the same time.

Fig. 3.e

Important warnings:

• By applying the appropriate impedance, a serial port with Master

(FBus) hardware supplies the network with the bias voltage required to run all the connected devices, i.e. the master itself and its slaves.

• Conversely, serial ports with slave hardware (BMS) do not provide bias

voltage, so it is always advisable to connect at least one device with master hardware (FBus) to the network so that it is correctly biased.

• However, no more than two devices with master hardware (FBus) can

be connected to the same network, otherwise the network’s total bias impedance becomes too small and incapable of supplying the required voltage to the RS485 network.

• We recommend connecting the serial probes or other ﬁ eld devices to

an optically-isolated version of the Fieldbus serial port or to serial port TWO – Fieldbus 1 to exploit the ﬁ ltering properties of optical isolation.

Special cases

• In networks consisting only of slave HW devices, no more than 207

devices can be connected. The max. length allowed for the network is 100 m.

DO NOT connect the 120, 1/4W terminating resistors to the  rst and last devices;

• In networks consisting only of Master HW devices, no more than 2

devices can be connected. The max. length allowed for the network is 1000 m. If the network is longer than 100 m, apply the 120Ω, 1/4W terminating resistors to the ﬁ 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.

4.2 Installation

Environmental conditions

Avoid installing the controller and the terminal in places with:

• exposure to direct sunlight and to the elements in general;

• temperature and humidity outside the product’s range of operation

(see “Technical Speciﬁ cations”);

• large, rapid ﬂ uctuations in room temperature;

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

near transmitting antennas);

• strong vibrations or knocks;

• presence of explosives or ﬂ 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 is protected from knocks or impacts. The controller should be placed inside the panel in a position where it is physically separated from power components (solenoids, contactors, actuators, inverters, etc.) and their respective cables. The ideal solution is to house these two circuits in two separate cabinets. Proximity to such devices/cables may cause random malfunctions that are not immediately evident. The panel’s casing must allow an adequate ﬂ ow of cooling air.

ENG

pCO5plus +0300020EN rel. 1.2 - 07.11.2013

Important:

• For safety reasons the controller should be installed inside an electrical

panel so that the only accessible parts are the display and the built-in terminal’s keypad.

• Install the controller so that the disconnection devices can be used

safely and without hindrance.

• When laying out the wiring, separate as much as possible the probe

cables, digital input cables and serial line cables from the power cables (connected to contactors, thermomagnetic devices, etc.) avoid electromagnetic interference.

• Never run power cables and probe signal cables in the same conduits

(including the ones in the electrical panels).

• For control signals, use shielded cables with twisted wires. If the control

cables have to cross over power cables, the intersections should be as close as possible to 90 degrees; under no circumstances should the control cables be laid parallel to the power cables.

• Keep the paths of the probe cables as short as possible and avoid

making spiral paths that enclose power devices.

• In case of malfunctions do not attempt to repair the device, but

contact a CAREL service centre.

Electrical installation

Important: Before servicing the equipment in any way disconnect

the controller from the power mains by putting the system’s main switch on OFF.

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 Speciﬁ cations” table. In environments subject to strong disturbance use shielded cables with the braiding bonded to the earthing conductor in the electrical panel. The terminals can accept wires with a maximum cross-section of 2.5 mm2 (12 AWG). After making the connection, gently tug on the cables to make sure they are suﬃ ciently tight.

Note:

• secure the cables connected to the controller with clamps placed at 3

cm from the connectors;

• if the power transformer's secondary winding is earthed, make sure

the earth conductor is bonded to the conductor that goes to the controller and is connected to terminal G0. This applies to all the devices connected to the controller through a serial network.

Important:

• Using a supply voltage other than speciﬁ ed can seriously damage the

system.

• Connect the fuse close to the controller.

• Installing, servicing and inspecting the controller should be done

only be qualiﬁ ed personnel and in compliance with national and local regulations.

• All the very low voltage connections (24 Vac/Vdc or 28 to 36 Vdc

analogue and digital inputs, analogue outputs, serial bus connections, power supplies) must have reinforced or double insulation from the power mains.

• Avoid touching or nearly touching the electronic components

mounted on the boards to avoid electrostatic discharges from the operator to the components, which can be very damaging.

• Do not press the screwdriver on the connectors with excessive force,

to avoid damaging the controller.

• Using the device in any way other than speciﬁ ed by the Manufacturer

can compromise its protection system.

• 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 pCO5+ are insuﬃ 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:

1. Locate the Fieldbus or BMS serial port.

2. Using a screwdriver, take oﬀ the cover.

3. Using a pair of nippers, cut out the perforated plastic part to create

an opening.

4. Plug the optional card into the edge-card connector, making sure it

is ﬁ rmly secured and makes contact.

5. Put back the cover so that the serial card’s connector is aligned with

the opening.

6. Make the electrical connections required.

See instructions sheet code +050003265.

Installing the Ultracap module

See instructions sheets codes +0500042IE and +0500041IE.

4.4 Serial network electrical connections

To improve the controller’s immunity against electromagnetic interference, the serial connection cable should be a shielded twisted pair cable, 2-pole or 3-pole depending on the insulation of the serial connection. The following rule applies:

• if the serial port is isolated (functionally) from the power supply, a third

wire is required in the serial cable to act as a common reference for the controllers. If the serial port is not optically isolated and the common reference is already present, no third wire is required.

Technical speciﬁ cations for connections

Use a shielded, twisted pair cable (AWG 20-22) with inter-conductor capacitance <90pF/m.

4.5 Connecting the terminal

The controller and the terminal are connected to a pLAN network.

1: One pCO controller

When connecting the controller to the terminal, the following restrictions should be kept in mind:

1. the overall length of the pLAN network should not exceed 500 m.

Consequently, if the terminal is installed remotely the length of the terminal cable must be included in the total length;

2. the unshielded telephone cable can be used for a max. length of 50

m. Beyond this length use a 3-pole shielded cable (see table below);

3. in case of lengths greater than 200 m, the power supply for the

terminal must be provided separately;

4. no more than 3 terminals can be connected to the same pCO

controller. The terminals must be of the same type (e.g. all PGD1). One terminal is powered by the controller, and the other two by an external power supply;

5. except for PGD0/PGD1/PGDE, the other terminals should be powered

by separate power supplies.

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-pin telephone cable available from CAREL as an accessory (code S90CONN00*). The telephone connector provides both data transmission and the power supply for the terminal.

To make the connection:

• slip the connector into terminal J10 until it clicks.

To remove the connector:

• press lightly on the plastic catch on the connector and slip it out.

Be sure to avoid the terminal being powered by two power supplies. For that purpose, set jumpers J14 and J15 on board TCONN6J000 to interrupt the supply current.

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

4.6 Input/output labels

pCO5+ controllers are distinguished by size and provided with inputs and outputs and power supplies for the active probes most suitable for various applications. The features that depend on the model are:

• maximum number and type of inputs/outputs;

• availability of built-in driver for expansion valves.

Important:

• power the pCO5+ built-in driver with AC voltage only, with the

transformer’s secondary winding earthed;

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

controller;

• if the transformer’s secondary is earthed, make sure that the earth

conductor is connected to terminal G0. This applies to all the devices connected to the pCO through a serial network;

• if more than one pCO board is connected to a pLAN network, make

sure that the G and G0 references are observed (G0 must be maintained for all controllers);

• the power supply to the controller(s) and the terminal(s) should be

kept separate from the power supply to the other electrical devices (contactors and other electromechanical components) inside the electrical panel.

Note:

• the yellow LED on the controller lights up when the controller is

powered;

• refer to the diagrams in par. 4.4 in case of controllers connected to a

pLAN network and installed in the same electrical panel or in separate panels.

5.2 Universal inputs/outputs

Universal inputs/outputs are distinguished by the letter U... They can be conﬁ gured from the application program for many diﬀ 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-conﬁ 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.

Note: The table shows the maximum number of inputs that can be connected. For example, a Small controller can be connected to a maximum of ﬁ ve 0 to 1 Vdc inputs from controller-powered probes and a maximum of ﬁ ve 0 to 1 Vdc inputs from externally powered probes. In any case, the maximum number of inputs of both kinds that can be connected is 5.

Remote connection of analogue inputs

The table below shows the required cable sizes to use for the remote connection of the analogue inputs.

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 separated from the power cables as much as possible (at least 3 cm). Never run power cables and probe signal cables in the same conduits (including the ones in the electrical panels).

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 conﬁ gured at 0 to 1 V or 4 to 20 mA.

Important: For temperature probes use the 4 to 20 mA or NTC conﬁ guration, as the 0 to 1 Vdc signal is limited to the 0 to 1 V range and is therefore not always compatible with the standard 10 mV/°C signal of CAREL probes (at temperatures below 0 °C or above 100 °C a probe alarm may be triggered).

5.3 Digital inputs

The controller features digital inputs for connecting safety devices, alarms, device status indicators and remote switches. These inputs are all optically isolated from the other terminals. They can work at 24 Vac (+10/15%) or at 28 to 36 Vdc (-20/+10%) (indicated with ID*), and some also at 230 Vac (indicated with IDH*).

Note:

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

RC ﬁ lter in parallel with the coil (typical ratings are 100 Ω, 0.5 μF, 630 V);

• if the digital inputs are connected to safety systems (alarms), the

presence of voltage across the contact should be taken as the normal operating condition, while no voltage represents an alarm situation. This will ensure that any interruption (or disconnection) of the input will also be signalled;

• do not connect the neutral in place of an open digital input;

• always interrupt the phase.

Important:

• to avoid electromagnetic interference, keep the probe and digital

input cables separated from the power cables as much as possible (at least 3 cm). Never run power cables and probe signal cables in the same conduits (including the ones in the electrical panels).

24 Vac digital inputs

The ID... digital inputs can be controlled at 24 Vac.

Note:

• the digital inputs are only functionally isolated from the rest of the

controller;

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

provide a separate power supply for each input;

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

of the controller.

Cable section

The cables used for remote connections to the digital inputs should have the following cross-section:

Cross section for lengths <50 m = 0.25 (mm2)

Important: If the controller is installed in an industrial environment (standard EN 61000-6-2) the connections must be less than 30 m long. Do not exceed this length to avoid measurement errors.

230 Vac digital inputs

Medium and Extralarge models feature one group of 230 Vac inputs (terminal J8), while Large models have two groups (on terminals J8 and J19). Each group consists of two digital inputs that can be powered at 230 Vac, indicated with IDH*, and two inputs that can be powered at 24 Vac/ Vdc, indicated with ID*. The two groups of 230 Vac inputs have double insulation between themselves and between them and the controller. The digital inputs that are connected can be the 24 Vac/dc inputs of one group and the 230 Vac inputs of the other. The two inputs of each group have the same common pole. Operational insulation is used. In each group, the digital inputs must be powered

at the same voltage (24 Vac, 28 to 36 Vdc or 230 Vac) in order to avoid dangerous short-circuits and/or the risk of powering lower-voltage circuits with 230 Vac electricity.

Note:

• the range of uncertainty of the switching threshold is from 43 to 90 Vac;

• the voltage must be 230 Vac (+10/-15%), 50/60 Hz.

5.4 Optically-isolated analogue outputs

0 to 10 V analogue outputs

On terminals VG and VG0 the controller provides optically-isolated 0 to 10 V analogue outputs, to be powered externally at the same voltage powering the controller, i.e. 24 Vac or 28 to 36 Vdc. La ﬁ gure below shows the connection diagram. The 0 V supply voltage is also the voltage reference of the outputs. See the Technical Speciﬁ cations table for details on the output current, output impedance, etc.

Note:

• the analogue output can be connected to module code CONVONOFF0

to convert the 0 to 10 V output into an ON/OFF relay output;

• a 0 to 10 Vdc analogue output can be connected in parallel to other

outputs of the same type, or alternatively to an external source of voltage. The higher voltage will be considered. Correct operation is not guaranteed if actuators with voltage inputs are connected;

• if optical isolation is not required, the VG-VG0 analogue outputs can be

powered at the same voltage on G-G0: connect G0 to VG0 and G to VG.

Notes:

• connect the valve cable shield to the blade (faston) connector and

then earth;

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

Technical Speciﬁ cations table and the EVD Evolution driver manual.

Apply the Ultracap module (accessory code PCOS0WUC20) on the controller with built-in valve driver. 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 it is applied to.

Important: The pCO5+ with built-in driver and PCOS0WUC20 module (or EVD0000UC0 external Ultracap module and 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.

Notes:

• the built-in driver replicates all the hardware and logic functions of the

“EVD Evolution” controller in case of 1 valve and of the “EVD Evolution TWIN” controller in case of 2 valves. In other words, it independently controls one or two electronic expansion valves with two-pole stepper motors. The only diﬀ 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 (code +0300005IT for single driver, +0300006IT for double driver);

• as with EVD Evolution, the internal driver on the pCO5+ controller

is available in the CAREL and the “Universal” versions. “Universal” models are used to control both CAREL electronic expansion valves and products made by other manufacturers (see the Technical Speciﬁ cations table), while CAREL models only control CAREL valves.

Serial communication and programming

Communication between the pCO5+ and its built-in driver is managed internally through the FBus2 serial port. The FBus2 serial port (J26) is however electrically isolated from the driver’s serial line; this ensures that in case of external faults on the line connected to FBus2, the internal driver can keep on working independently. The driver can only be conﬁ gured using the pCO5+ application developed with 1Tool; no external displays are available for the driver.

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

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

Important: To ensure eﬃ cient data exchange between the driver and the controller, when developing the 1Tool application, if there are devices connected to the FBus2 port (terminal J26) using the Modbus® protocol, developers should take into account the number of variables exchanged over the entire serial line.

5.6 Digital outputs

Electromechanical relay digital outputs

The controller features digital outputs with electromechanical relays. For ease of installation, the common terminals of some of the relays have been grouped together.

The type of insulation is described in the table below. See also the Technical Speciﬁ cations table.

Type of insulation

Between relays in the same group operational insulation Between groups of relays reinforced insulation Between relays and the rest of the controller

reinforced insulation

Notes:

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

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

• between groups there is reinforced insulation, so diﬀ erent groups can

have diﬀ erent voltages.

5.7 Solid state relay (SSR) digital outputs

pCO5+ controllers are also available in versions with solid-state relays (SSR) for controlling devices that require an unlimited number of switching cycles that would not be supported by electromechanical relays. These outputs are dedicated to resistive loads powered at 224Vac SELV or 28 to 36 Vdc SELV with max. load current up to 1A or 230 Vac with max. load current up to 70mA.

(*) Dedicated power supply or same power supply as controller: not in common with the power supply for other external loads (e.g. contactors, coils).

Important: In applications with SSR outputs:

1. the controller should drive only resistive loads with loads current less

than maximum declared;

2. use an additional external SSR to drive inductive loads;

3. for AC power supply to resistive loads or external SSRs,

4. use the same power supply as the controller (connected to terminals

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 Switch-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 terminals

All pCO5+ controllers can be connected to each other and to other CAREL devices in a pCO local area network (pLAN) without requiring optional devices, allowing the communication of data and information from one location (node) to another. The terminals can show the variables (temperature, humidity, pressure, I/O, alarms) from just one controller at a time. The terminal does not need to be connected to the controller during normal operation, but can be used just for the initial programming of the main parameters. If one or more terminals are disconnected or malfunctioning, the application program continues to work correctly on each controller. Generally, the application program can monitor the status of the network and intervene as necessary to ensure the continuity of control functions. The ﬁ gure below shows a possible pLAN network connection diagram.

All the terminals and controllers in the network must communicate at the same speed. The speed is adjusted automatically. A maximum of 32 units can be connected, including:

• pCO controllers, which run the control program;

• external modules, which provide extended functionality (such as the

EVD Evolution driver);

• terminals.

Every device belonging to a pLAN network is identiﬁ ed by an address, i.e. a number from 1 to 32. The number 32 can be assigned only to a terminal. Programs for diﬀ erent applications (e.g. chillers, air-conditioners, compressor racks, etc.) cannot be automatically integrated into a local network – they must be conﬁ gured according to the system’s architecture using the CAREL development tool. Each controller connected to the network can simultaneously manage up to 3 terminals in the pLAN network. The values are displayed on the terminals at the same time and not independently, as if the keypads and the displays were connected in parallel. Because of that, the controller cannot drive diﬀ erent kinds of terminals at the same time.

Each terminal associated with a certain controller is deﬁ 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 pCO constantly updates the displays on the private terminals, while the shared terminals (if present) are updated only by the pCO that is controlling the terminal at that time.

The ﬁ gure below illustrates the logic of the relations.

In this example the shared terminal is associated with 4 pCO controllers, but at this instant only controller 1 can display data and receive commands from the keypad. Switching between controllers occurs in sequence (1>2->3->4->1...) by pressing a button deﬁ ned by the application program; however it can also be done automatically when requested by the program. For example, a pCO may request control of the shared terminal to display alarms or, vice-versa, relinquish control to the next pCO after a set time (cyclical rotation). Data on the number and type of terminals is determined during initial network conﬁ guration and saved in the permanent memory of each pCO controller. Details of the conﬁ 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’s address

The controller’s pLAN address is factory-set as 1. There are two ways to set a controller’s address:

1. using the A button (see ﬁ gure below) located on the left of the

7-segment display. It can be accessed using the tip of a screwdriver (ø<3 mm);

2. using a terminal connected to the pLAN network.

1. Displaying the pLAN address

Procedure:

• brieﬂ y press the A button (no more than 5 s) to display the controller’s

current pLAN address. Five seconds after releasing the button the display is cleared.

2. Press repeatedly or hold the button until reaching the desired

address (e.g. 7), then remove the screwdriver.

3. Wait until the address starts ﬂ ashing quickly. The address is now

saved but is not yet active for the application program.

4. Power oﬀ the controller.

5. Power on the controller. The address is now active.

2. Setting the address using an external terminal

The controller is assigned a private (Pr=private) or shared (Sh=shared) terminal with address 32. The external terminal can be given an address from 0 to 32. Addresses between 1 and 32 are used by the pLAN protocol, while address 0 identiﬁ es the Local Terminal protocol, used for point-topoint connections and to conﬁ gure the controller (this can be done with a single pGD terminal and a single pCO). If the controller with default setting (address=1) is connected to an external terminal (address=32), communication is established and the external terminal replicates the display on the built-in terminal, if featured. If however the controller has a diﬀ erent address (e.g. 7) and the terminal is not set to communicate with the controller at this address, once the connection is established the terminal will display a blank screen. In this case, proceed as follows.

Procedure:

1. Press the UP, DOWN and Enter buttons together to go to the screen

for setting the terminal address.

6.5 Uploading software

The following methods can be used to update the ﬁ rmware and acquire the log ﬁ les on pCO controllers:

• smart Key programming key;

• pCO Manager, a program to install on the PC;

• a pendrive.

If you are using a pendrive, before proceeding you must connect the terminal to the controller following the instructions in par. 4.5 and then establish the connection. The terminal can be either private or shared.

Smart key

The PCOS00AKY0 key is an electronic device used to program and service pCO Sistema controllers. The PCOS00AKY0 key simpliﬁ es data transfer between the controllers installed and a personal computer by exploiting the high capacity ﬂ ash memory for storing software applications, BIOS and variable logs. The pCO is connected directly via the telephone connector using the cable supplied, while to transfer data to a personal computer the PCOS00AKC0 USB adapter is required. The device is powered either by the USB port on the PC or by the controller, therefore no external power supply is necessary.

pCO Manager

On all pCO Sistema controllers the resident software can be updated using a PC. For this purpose, CAREL provides the pCO Manager program and a serial converter with RS485 output to connect to the pCO. pCO Manager is part of the “1Tool” program suite; it can also be installed by itself and can be obtained free of charge at http://ksa.carel.com, from the section “pCO Sistema”-> “pCO_manager”. The ﬁ gure below shows the connection diagram.

The controller can be connected directly to the PC via the RS485 serial port used for the “pLAN” connection or via the BMS or Fieldbus serial port using the optional RS485 serial card. Lastly, connection can be made using the slave USB port, if present. pCO Manager can communicate with all the programmable controllers of the pCO family. The program can also be used to update and download to the PC the BOOT, BIOS, application program, conﬁ guration and log ﬁ les and also to save ﬁ les to the NAND ﬂ ash memory.

As a rule, CAREL advises NOT to update the BOOT; CAREL always loads the BOOT best suited for the controller’s operation during construction. Only in very special cases will CAREL ask the user to update the BOOT. The BIOS can only be updated via the pLAN serial connection. This procedure causes the controller to switch to low-level operation. In this operating mode log data cannot be downloaded to the PC. To bring the controller back to normal communications with pCO Manager, reset the pCO after successfully loading the BIOS. For further information on the operation of pCO Manager see the online help inside the program. Download options are shown in the table below.

NAND  ash memory

This type di memory is included on all pCO5+ controller versions. pCO Manager can be used to load any type of ﬁ le to the NAND ﬂ ash memory. It can be used, for example, to save the source ﬁ les of the application program being used. In addition, the IUP, BLB (or BIN) and DEV ﬁ les that represent parameter ﬁ les, the screens displayed in the various languages and the control logic can be loaded to the NAND ﬂ ash memory and then selected from the terminal screen to be used as the current application on the pCO. Speciﬁ cally, several diﬀ erent applications, or diﬀ erent languages, or multiple parameter ﬁ les can all be loaded in the NAND ﬂ ash memory, after which the desired application, language or parameter conﬁ guration can be selected and loaded to the main ﬂ ash memory. The ﬁ les saved in the NAND ﬂ ash memory can be selected and copied to the main ﬂ ash memory on the screen managed directly by the BIOS. The procedure is described in paragraph 6.6. Limitations:

• a maximum of 40 ﬁ les can be saved on the NAND ﬂ ash memory;

• the memory’s total storage capacity is 50 MB.

Pendrive

Some controller models come with two diﬀ erent USB ports (host and slave) to be used for installation and diagnostics. The host port can be used to connect USB mass storage peripherals (pendrives, portable hard disks, etc., having a maximum current consumption of 500 mA) with which to carry out various operations:

1. upload to the controller ﬁ les contained in the removable peripheral

(e.g. application, parameters in the buﬀ er memory, conﬁ guration ﬁ les for logs, BIOS);

2. download ﬁ les from the pCO5+ to the removable peripheral (e.g.

application, parameters in the buﬀ er memory, data logs, BIOS).

Note: Using the pendrive to perform the following operations:

• UPLOAD - copying ﬁ les from the pendrive to the controller;

• DOWNLOAD - copying ﬁ les from the controller to the pendrive is

possible only when using a terminal, either built-in or connected to the controller via pLAN.

The controller can be provided with 2 USB ports which can be accessed by removing the cover (see chap. 2).

The keypad has 6 buttons that, pressed alone or in combination, can be used to perform all the UPLOAD and DOWNLOAD operations between the pendrive and the controller.

Important

• before the pendrive can be used it must be formatted to the FAT32

ﬁ le system;

• the pendrive can be accessed up to two levels – APPL\CHILLER\PRI.BIN

– but access to ﬁ le \APPL\CHILLER\VER1\PRI.BIN is not allowed;

• do not use both USB ports at the same time;

• the maximum pendrive capacity supported is 32 GB.

Manual, automatic and autorun mode

• manual mode involves selecting the operations to be performed via

the keypad; this oﬀ ers maximum ﬂ exibility and the possibility to freely decide which operations to perform;

• automatic mode requires creating special ﬁ les called conﬁ guration

ﬁ les. These are text ﬁ les (.txt extension) containing various types of information on the functions to perform and the ﬁ les to load;

• autorun mode requires creating a special conﬁ guration ﬁ le called

“autorun.txt”. When the pendrive is plugged, in the controller immediately executes Autorun and upon conﬁ rmation from the terminal performs the operations contained in the ﬁ le.

Upload and Download

UPLOAD can be performed in three diﬀ erent ways:

1. manual mode: the user selects manual mode from the keypad, then

the ﬁ les to load, and then conﬁ rms to start the operation;

2. automatic mode: the user selects automatic mode from the keypad

and then the conﬁ guration ﬁ les containing the instructions on the operations to carry out;

3. autorun mode: after the pendrive is plugged in, a screen is displayed

indicating that Autorun mode has started. After conﬁ rming, the instructions contained in “autorun.txt” are executed automatically. The contents of this ﬁ le are similar to the UPLOAD conﬁ guration ﬁ les, the only diﬀ erence being the name “autorun.txt”.

DOWNLOAD can be performed in two diﬀ erent ways:

1. manual mode: the user selects manual mode, then the ﬁ les to

download, and then conﬁ rms to start the operation;

2. autorun mode: after the pendrive is plugged in, a screen is displayed

indicating that Autorun mode has started. After conﬁ rming, the instructions contained in “autorun.txt” are executed automatically. The contents of this ﬁ le are similar to the DOWNLOAD conﬁ guration ﬁ les, the only diﬀ erence being the name “autorun.txt”.

Note: The conﬁ guration and autorun ﬁ les must reside in the main

directory.

The steps to follow are described in par. 9.3.

6.6 Checking the software installed and

other information

Users can at any time check the version of the current program (by CRC code, expressed in hexadecimal), and also whether it is being used by the key or by the resident program. To do this, proceed as follows.

Screens managed by BIOS

Press the ALARM and ENTER buttons together for 3 seconds. The following screen will appear.

>SYSTEM I NFORMATI ON

LOG DATA OTHE R I NFORM ATI ON FLASH /USB MEMORY

Each of the four lines displayed is used to access further screens, managed by BIOS and consequently always available regardless of the application loaded. To access the functions, select the line with the cursor “>” using the UP and DOWN buttons and then press ENTER to conﬁ rm. To exit the screen press MENU or Esc on the terminal, or wait around 40 seconds for automatic timeout. The screens provide the following information.

1. SYSTEM INFORMATION: Selecting this function displays information on the software loaded and the amount of RAM and ﬂ ash memory installed. The screen displayed is similar to the following.

BOOT V 4. TE 6/ 12/ 11 BI OS V 6. TE13/01/ 12 >2+ 7 MB < A_CRC: 0000- 3617 MB

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

4. FLASH/ USB MEMORY: Selecting this string displays the following screen.

> NAND FLASH F I LES

USB PEN DRI VE

The ﬁ rst selection lets you view the names of the IUP, BLB, GRP and DEV ﬁ les contained in the NAND memory. You can also copy an application from the NAND memory to the pCO’s main ﬂ ash memory. Each ﬁ le name is shown on a screen such as the one below.

[X]

PGD23_ALL.grp

To move from one ﬁ le to another press the UP or DOWN button. Press ENTER to select the current ﬁ le to copy to the main ﬂ ash memory. The ﬁ les selected to be copied are marked by an “X” on the ﬁ rst line of their respective screens. In the example shown, the “PGD23_ALL.grp” ﬁ le is selected to be copied. To start the copy, press UP or DOWN until the following screen appears:

Press Enter

to star t copy ing

and then press ENTER to conﬁ rm. See the pCO Manager manual for further information on using the NAND memory.

To exit these two screens press Menu on the local terminal or wait around 40 seconds for automatic timeout.

Notes:

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

cables. Never run power cables and probe signal cables in the same conduits (including the ones in the electrical panels);

• the two 230 Vac or 24 Vac/Vdc inputs on terminals J8 (ID13, ID14) or J19 (ID15, ID16) have the same common pole and must therefore be powered at the same

voltage (230 Vac or 24 Vac/Vdc). The two inputs are provided with operational insulation; reinforced insulation is provided between the inputs and the rest of the controller;

• ID1 to ID8, ID9 to ID12, ID17, ID18 are functionally isolated from the rest of the controller;

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

• the rating of the external contact connected to the digital inputs must be at least 5 mA;.

Warnings:

• for lengths greater than 10 m use a shielded cable with earthed shield;

• a 0 to 10 Vdc analogue output can be connected in parallel to other outputs of the same kind, or alternatively to an external source of voltage. The higher voltage

will be considered. Correct operation is not guaranteed if actuators with voltage inputs are connected;

• power the VG-VG0 analogue outputs at the same voltage on G-G0: connect G to VG and G0 to VG0. This applies in case of both alternating or direct current power

Insulation distance

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

Warnings:

• 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.

Optional Ultracapacitor module (PCOS0WUC20 or EVD0000UC0). If the controller works constantly at temperatures near the upper limit of 60°C it is recommended to use the external module code EVD0000UC0, if possible placed in the coolest point of the panel. Modules PCOS0WUC20 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.

*: Default mode

The key is factory-programmed in read/write mode (type C) so that it can be used immediately to transfer software from one controller to another. When the key is connected to the personal computer, the symbols have the following meanings:

Flashing Waiting for connection to PC Alternating When connected to PC indicates data transfer in

progress

The programming key is compatible starting from BIOS version 3.43 and BOOT version 3.01. For more detailed information on programming the key, see the pCO Manager program manual.

Using the Smart Key with the pCO

Switch oﬀ the pCO, remove any peripherals connected in the pLAN and plug the key into the telephone connector on the controller. When switching on again, all the symbols light up momentarily and the buzzer emits a beep. A few seconds later the key becomes operational. During this period the symbols

will ﬂ ash. The controller then enters programming mode and the start button lights up steadily. Press the button to start data transfer.

Important: If the key is type B, C or G (in write mode) pressing the start button will immediately delete the software already loaded on the pCO.

Important: Do not remove the key while data is being transferred to the key itself, as the ﬁ le being transferred will be lost and the corresponding space will not be restored. To restore the original capacity all the ﬁ les will need to be deleted. If the key is type “C” or “G”, simply perform a new application read operation.

Meanings of Buttons/Symbols

Flashing: The key is connecting to the pCO. During this phase, which may last a few seconds, the start button is disabled.

start Flashing: The key has detected the pCO and is checking the

access rights.

Commissioning: basic concepts

Note: The following paragraphs are from the online help of pCO

Manager, to which the user is referred for further details.

Commissioning is a conﬁ guring and real-time monitoring software that can be used to supervise the performance of an application program installed on a pCO, to start up the pCO and to perform debugging and maintenance.

With this software the user can set the conﬁ guration parameters, edit the values of volatile and permanent variables, save on ﬁ le the trends of the unit’s main quantities, manually manage the unit’s I/O using simulation ﬁ les and monitor/reset the alarms of the unit on which the device is installed.

Work carried out with Commissioning is preceded by conﬁ guring the work environment, which is typically done by the project designer. The active project in 1Tool is automatically loaded by pCO Manager.

The project designer can use the conﬁ guration functions of Commissioning to decide which variables should be subjected to monitoring, logging, trend-monitoring and event-monitoring, to organize variables into categories and to create sets of conﬁ guration parameters.

Operators using Commissioning for maintenance will be able to see the necessary variables and to draw from preset conﬁ guration values.

Support  les

Once the design of the application is completed, 1Tool generates a number of ﬁ les in the compiling stage, two of which are required by Commissioning:

• <nomeApplicativo>.2CF [<ApplicationName>.2CF] (variable descriptor)

• <nomeApplicativo>.2CD [<ApplicationName>.2CD] (category and

access proﬁ le descriptor)

In addition to these ﬁ les, the software also manages the <nome applicativo>.DEV [<Application Name>.DEV] ﬁ le, which contains the unit’s preset parameters.

When the user has ﬁ nished using Commissioning, whether for conﬁ guration or monitoring purposes, the following ﬁ les can be generated:

• <nomeApplicativo>.2CW [<ApplicationName>.2CW] (descriptor for

categories, access proﬁ les, monitoring groups)

• <nomeﬁ leCommissioningLog>.CSV [<FilenameCommissioningLog>.

CSV] (ﬁ le used for the commissioning log, containing data of the variables logged during monitoring)

Therefore, to conﬁ gure Commissioning the following ﬁ les are required: .2CF, 2CD and, if necessary, the .DEV ﬁ le, which can be imported or exported.

For monitoring purposes, in addition to the ﬁ les above, it might also be necessary to have the .2CW ﬁ le, containing the deﬁ nition of the work environment. The commissioning log ﬁ le is a simple output ﬁ le.

pCO Load: basic concepts

pCOLoad is the module that manages:

• uploading to the ﬂ ash memory (of the device or of the ProgKeyX key

installed on the pCO);

• uploading to the NAND memory of certain devices;

• downloading the log ﬁ le, .DEV ﬁ le and P memory (from the ﬂ ash

memory);

• downloading ﬁ les from the NAND memory, if present.

The ﬁ les exchanged with the Flash memories of pCO controllers are:

• BOOT.BIN (download reserved, upload enabled from menu)

• BIOS.BIN (download reserved)

• <nomeApplicativo>.BLB [<ApplicationName>.BLB] (download

reserved)

• <nomeApplicativo>.BIN [<ApplicationName>.BIN] (download reserved)

• <nomeApplicativo>.DEV [<ApplicationName>.DEV]

• <nomeApplicativo>.GRT [<ApplicationName>.GRT] (upload only, from

which the .GRP ﬁ le is extracted)

• <nomeApplicativo>.IUP [<ApplicationName>.IUP]

• <nomeApplicativo>.LCT [<ApplicationName>.LCT]

• <nomeApplicativo>.PVT [<ApplicationName>.PVT]

• <nomepCOlog>.BIN, <nomepCOlog>.CSV, <nomepCOlog_GRAPH>.

CSV [<pCOlogName>.BIN, <pCOlogName>.CSV, <pCOlog_ GRAPHName>.CSV] (only if log ﬁ les have been conﬁ gured, download only).

The ﬁ les exchanged with the NAND memories of pCO controllers are:

• any ﬁ le that the pCO can independently copy to the ﬂ ash memory (see

above list);

• external ﬁ les (e.g. .pdf or .doc ﬁ les for documentation).

LogEditor: basic concepts

LogEditor is the module used to conﬁ gure the log ﬁ les of pCO devices (pCO logs). Conﬁ guring pCO logs consists in deﬁ ning a number of sets of variables in which to specify which variables should be logged, the logging method (by frequency or by event) and the minimum number of loggings required. Conﬁ guration is based on a binary ﬁ le (.PVT – Public Variable Table), which is generated by 1Tool and contains the descriptive data of the variables that can be logged.

All the log conﬁ gurations so deﬁ ned are saved in the .LCT (Log Conﬁ guration Table) binary ﬁ le, which must be uploaded to the pCO together with the .PVT ﬁ le. Log conﬁ guration data is also saved in a ﬁ le that can be used only by LogEditor – the .LEF ﬁ le, which must be saved to be edited with LogEditor as necessary.

LogEditor can be used even when the device is not connected.

Once the ﬁ les for logging are uploaded to the pCO, the pCO saves the logged data in the following ﬁ les:

• .BIN ﬁ le containing all the data in binary format;

• .CSV ﬁ le containing the same data in a generic format with values

separated by commas;

• *_GRAPH.CSV containing the same data to be used for charting purposes

9.3 Pendrive: operating instructions

File extensions, names and contents

Various types of ﬁ les can be uploaded and downloaded and are distinguished by their extension.

File names

In order to be recognised, the names of the directories and ﬁ les on the pendrive must have no more than 8 characters; the controller makes no distinction between upper-case and lower-case characters. However, during DOWNLOAD the names of the directories created by the controller on the pendrive are always in upper-case.

FILE TYPES FOR UPLOAD

File extension

Description

.IUP Contains the deﬁ nitions of the screens on the terminal .BLB Contains the application .BIN Contains the application (with pLAN table) .BLX Contains the logic of atoms custom in C language .GRP Contains the graphics .DEV Contains the preset conﬁ guration parameter values PVT, .LCT Contains the descriptions of the public variables to be

logged. Generated by 1Tool, this is used by the LogEditor module and must be loaded together with the .LCT ﬁ le

Downloaded ﬁ les are saved in directories created automatically, with the following name format:

NAMXY_WZ Where: NAM: identiﬁ es the type of data downloaded (LOG for logs, BKP for the application, DEV for the buﬀ er memory, CPY for all the data from the controller). XY: progressive number from 0 to 99 WZ: controller pLAN address.

Example: A directory named LOG00_01 contains the log ﬁ les (LOG) downloaded from a device whose pLAN address is 1. Since the key contained no directory of this type before download, it is indicated with

00.

Important: No more than 100 ﬁ les of the same type can be downloaded to the pendrive, as the directories created can only be numbered with XY=00 to 99.

FILE TYPES FOR DOWNLOAD (controller pLAN address = 1)

File extension Directory name Description

Important: As can be seen, when updating the BIOS and the application, the pGD1 terminal shows the message “NO LINK”, meaning that no connection is established. Do not remove the terminal and wait for the end of the update procedure, when the pGD1 terminal replicates the messages on the built-in display.

Note: Autorun run is especially useful in those cases in which the same operation needs to be performed on several controllers. For example, to load diﬀ erent applications on controllers connected in a pLAN network, only one autorun ﬁ le needs to be created; this uploads the various directories contained on the pendrive based on the address of the controllers. The controller with address XY will only load the directory called “nomedir_XY” [“DirName_XY”]. The pendrive then only needs to be plugged into each controller to run the upload, conﬁ rming from the shared terminal.

Manual upload

To manually upload the contents of the pendrive the user must access the management menu from the system screens, selecting UPLOAD and then MANUAL. The ﬁ les are selected by pressing ENTER when the cursor is on the desired ﬁ le name. A selected ﬁ le is marked by the symbol “*” on the left. Once the ﬁ les have been selected (all in the same directory), press PRG to start the upload. To display the contents of a directory press ENTER. To go up one directory level press ESC. Once the upload has started, the messages shown on the screen are the same as in automatic and autorun mode.

Download

As mentioned above, the DOWNLOAD operation can be managed in two ways:

1. Manual mode: follow the steps described in the paragraph “Automatic upload” and select manual operation. Then each ﬁ le must be selected and downloaded.

2. Autorun mode: prepare a ﬁ le called “autorun.txt”, containing a string that identiﬁ es the function to be performed.

Function String

DOWNLOAD logged data Download logs

DOWNLOAD the application Download application

DOWNLOAD non-volatile memory

Download non volatile memory (.dev)

DOWNLOAD the entire contents of the pCO

The result is the creation of ﬁ les with the required extensions, which will be placed in the respective directories as described in the paragraph “File names”. When the operation is completed, the display shows a message with the name of the directory created.

Example: On the controller with address 1, the autorun ﬁ le will create a directory called BKP00_01 and copy the ﬁ les APPL_PCO.DWL and FILE_ DEV.DEV to this directory.

Setting the password

If the application contains a password that must entered in a special screen, this is requested for each DOWNLOAD/UPLOAD between the pCO and the pendrive. The password is used to:

• protect the contents of the pCO from being downloaded to the

pendrive;

• protect the PC connection (this is a standard procedure in pCO Manager).

Connecting to a computer

Connect the slave USB port on the controller to the USB port on the computer where pCO Manager is installed.

Important:

• do not install any type of converter between the computer and port B, even if requested by the program’s guided procedure;

• pCO Manager manages compressed ﬁ les (.GRT/.OS). Once the connection is established, the following operations are available:

1. UPLOADING the application or BIOS+application.

2. DOWNLOADING the non-volatile memory.

3. DOWNLOADING logged data.

4. Commissioning

5. Managing the NAND ﬂ ash memory.

Once the USB cable is removed, the port will become available again after approximately 5 s.

Important: If no connection is established with pCO Manager after plugging in the USB cable, wait at least 1 minute before using the USB ports again after removing the cable.

9.4 Conﬁ guring pCOWeb/pCOnet from a

system screen

See par. 6.6 for information on how to access the BIOS system menu. Starting from:

• BIOS release 5.16 BIOS, and from

• pCOWeb ﬁ rmware version A1.5.0, and from

• pCOnet ﬁ rmware version A485_A1.2.1

pCOWeb and pCOnet communication parameters can be conﬁ gured. The purpose is to conﬁ gure the network (Ethernet for pCOWeb, RS485 for pCOnet) when the respective card is installed for the ﬁ rst time. The remaining parameters (alarms, events, etc.) can be conﬁ gured using the usual tools, i.e. BACset or web interface (pCOWeb only). Conﬁ guration can be done either when using the Modbus protocol or the CAREL protocol, but only on the BMS1 serial port. The screens for conﬁ guring pCOWeb and pCOnet can be opened by accessing the system screens and selecting OTHER INFORMATION and then PCOWEB/NET CONFIG. Then, select “PCOWEB settings” to conﬁ gure pCOWeb parameters or “PCONET settings” to conﬁ gure pCOnet parameters.

Conﬁ guring pCOWeb

When you select “PCOWEB settings” the following screen will appear:

DHCP : - - -

I P ADDRESS

---.---.---.---

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