1. INTRODUCTION

1.1 Wireless monitoring devices

For the retro t of food refrigeration and room cooling systems, energy consumption measurement and I/O management via supervisor, CAREL proposes the rTM SE wireless system (Remote Temperature Monitoring). This solution guarantees the maximum in terms of:

• Flexibility;

• Functions;

• Reliability;

• Easy operation

• Reduced installation costs;

• Easy commissioning/service;

• Integration with the most common BMS (Building Management Systems);

This solution ensures considerable savings in terms of installation costs (eliminating the cost of wiring), o ering  exibility in the layout of supermarkets and allowing faster retro t installation. Ideal for all installations where electrical wires cannot be laid, i.e. properties that do not have raised  oors or false ceilings.

The retro t of existing systems is required for compliance with HACCP standards, for monitoring the systems via remote connections, for recording events and analysing them for scheduled maintenance.

The CAREL rTM SE system can be used in all industrial and trade businesses that require the prevention of risks relating to the safety and storage of food for human consumption, in accordance with the HACCP standards; moreover, it o ers the possibilit y to manage  exible spaces very simply, thus reorganising the layout of showcases in a supermarket without having an impact on the wired network (communication and power supply);

The system is a network of wireless sensors  tted inside the showcases, easy to con gure and install, connected to a Carel supervisor (PlantVisorPRO or PlantWatchPRO) for recording the temperature, events and alarm noti cations. The data measured and the alarms signalled are saved and can be accessed at any time, in compliance with EN 12830.

The system can be easily installed on all types of refrigeration unit (showcases or cold rooms), is independent of the controller installed on the unit and requires no additional wiring because the devices are wireless and battery powered, meaning signi cant cost savings.

The sensors require no electrical connections as they use a long life battery (typically 5 to 8 years, depending on the transmission frequency set), a wireless connection with ZigBee™ technology (mesh) at a transmission frequency of

2.4 GHz authorised for operation in all countries around the world, and are ready for connection to the most common BMS systems using Modbus® protocol. The sensors monitor the inputs (temperature, humidity, light and digital input status) and send the data wirelessly to the Access Point or Router. Communication between sensors and the Access Point is two way. The sensors, as well as sending the change in the status of the variables, can also receive data.

Moreover, a mains powered model has been designed for use in all applications that require frequent communication (e.g. monitoring  oating suction pressure).

In ambient monitoring applications, the temperature, humidity and light

intensity can all be recorded by simply installing battery powered sensors in the desired location. The sensors cover a wide range of uses in refrigeration, air-conditioning and humidi cation applications.

Many applications are also available for remote I/O management from supervisors

, as the module manages generic I/Os and saves on the cost of laying cables, without the need for separate power and signal cables. The wireless devices send the temperature and alarm data wirelessly to the Router and Access Point, which relay the information to the supervisory system

The CAREL rTM SE system consists of the following components:

• Battery powered devices:

- Temperature sensor from  tted inside the showcase, version BP SE (Built-

in Probe);

- Sensor with two external NTC probes and two digital inputs, version EP

SE (External Probe) for showcases and cold rooms;

- Room temperature and humidity sensor for installation in residential

environments,

version SA

- Temperature, humidity and light sensor, SI industrial version;

- Pulse counter to be used with the energy meter module con gured for

pulse counters, version CI;

• Access Point. Wireless receiver that acquires data from the various sensors

in the ZigBee™ network, making such data available to the supervisor via Modbus® RTU over RS485. Up to 30 sensors can be directly associated with each Access Point, or a maximum of 60 if one or more Routers are used. The supervisor (PlantVisorPRO or PlantWatchPRO) can thus see all the variables in the rTM SE system;

• Router. To be used when the distance between the Sensors and the

Router exceeds 30 m (relays the wireless signals so as to cover greater distances between the Access Point and sensors), or if there are more than 30 Sensors in the network. There can be a maximum of 60 Routers in the wireless network, 48 of which are visible to the supervisor. The Access Point automatically assigns a serial address in the order in which these are “bound”, starting from 200 up to 247. Five versions of Router are available, which also include other functions:

- Router powered at 230 Vac mains voltage, version RO;

- Router Bridge powered at 12-24 Vac, version RB. Integrates the function

to extend the RS485 network;

- Router Sensor powered at 12-24 Vac, version EP1. Integrates the functions

of the battery powered EP SE Sensor);

- Router-Actuator powered at 12-24 Vac, version RA. Integrates the

functions of I/O module or local thermostat;

- Router-Pulse Counter powered at 12-24 Vac, version RC. Integrates the

same functions as the CI battery powered pulse counter;

• Modbus® supervisor system: The rTM SE system is designed to be used

together with Carel PlantVisor PRO or PlantWatch PRO supervisors

Wireless transmission between the various devices uses standard ZigBee™ communication protocol and encryption technology with a Carel private key. This is an advanced system that has achieved an excellent level of security in data exchange for wireless communication and is used in many applications. The CAREL solution uses mesh technology between Access Points and Routers, ensuring more reliable communication and delivery of the data sent by the sensor.

Note: ZigBee wireless connection without interoperability.

rTM SE handheld: network analyser used to check the ZigBee wireless signal level and to open/close the wireless network when binding the devices (sensors and Routers), including the possibility to set the BP Sensor address and reset the Router and Access Point. Useful during installation;

1.3 Terminology

Wireless

Wireless means “without wires”, in contrast to the term wired.

Wireless network

Communications system (series of devices, appliances, methods and protocols) for the transmission of information via radio, typically radiofrequency technology used instead of wired connections, making the systems particularly  exible.

ZigBee™

Zigbee™ is a set of speci cations based on the IEEE-802.15.4 standard for the creation of Wireless Personal Area Networks (WPAN). Comparable in some ways to Bluetooth, it stands out for its very low power consumption and the reduced cost of implementation, despite having a maximum data transfer speed of 250 kbit/s. ZigBee™ devices, with compact dimensions and low costs, are designed to work in dedicated self-organised networks (Mesh networks) and are used in many  elds.

1.4 Advantages of the wireless system

Advantages of a wireless network over a wired network

• Mobility of sensors;

• Easy to install and connect the devices;

• Coverage even where obstacles are present;

• Flexibility in the event of structural modi cations;

• Reduction in wiring costs;

• Robustness.

The advantages of wireless networks can overcome some of the intrinsic limits in wired systems. Typical network infrastructure features a wired backbone with wireless access.

Advantages of ZigBee™

• Standard technology;

• Reduced costs;

• Can be used globally;

• Reliable;

• Supports a large number of nodes;

• Easy con guration;

• Long battery life;

• Secure data transmission.

The band centred around 2.45 GHz (used in the wireless sensor system for refrigeration) is the only one that can be used all over the world, without needing to apply for special licenses. In addition, the ISM band (Industrial, Scienti c and Medical) exploits the full potential of the standard, that is, can use 16 transmission channels with a bit rate of 250 kbit/s.

Types of nodes

ZigBee™ Access Point - Co-ordinator and Gateway;

- Must be available and on in every network

- Coordinates the creation of the network;

ZigBee™ Router;

- Participates in the delivery of the messages, and must always be on;

- Available in Router-Bridge version for extending a wired local network

(for a list of approved controllers, see chapter on the features of the Router), and EP1 Router-Sensor version.

ZigBee™ End-Device (sensors);

- Node with limited wireless functions;

- Low power consumption;

- Low cost;

For data communication with the Access Point, the end device uses a “parent” for e ective wireless transmission; this may be a Router or the Access Point itself.

Example of a Mesh network

The MESH layout, used in the wireless sensor system for refrigeration between coordinator nodes (access points) and router-bridge devices, ensures a high tolerance to faults, as if one sensor loses wireless communication, the radio signal still manages to  nd an alternative route to reach the destination.

1.7 Using the Router

When does the Router need to be installed? The Router is required whenever a direct connection is not possible between the Access Point and the Sensor; this may occur when:

• The distance between Access Point and Sensor is greater than 30 m MAX

with visibility between the instruments.

• There is no visibility between the Access Point and the Sensor, and/or

there is shielding infrastructure that reduces the wireless communication distance.

• In addition, the Router is required if the number of Sensors managed

exceeds 30 devices.

In addition, this is used to improve the reliability of the wireless connection, the Router network can in fact  nd an alternative path if one of the direct connections between the sensors and the access point fails.

Recommended:

Up to 15 sensors 1 Router; from 16 to 30 sensors 2 Routers; from 31 to 45 sensors 3 Routers; from 46 to 60 sensors 4 Routers.

1.8 General notes

The radio range of the devices is around a hundred metres in an open  eld, that is, without any obstacles. In a closed  eld the range varies signi cantly based on the type of environment and the surrounding objects (shelves, furniture, metal walls etc.). Thick partition walls or reinforced ceilings and  oors may represent impassable obstacles. The ideal position of the devices, especially the routers, often cannot be de ned theoretically but must be found by trial and error in the actual installation.

Serial address assignment is valid for all devices

Make sure not to assign the same serial address ID to two devices in the same wireless network.

Tab. 0.cTab. 1.c

The battery life is purely indicative and depends on the cycle transmission time set and the quality of the wireless connection. If the device does not communicate correctly with the Access Point (distance or interference problems) battery life will be reduced due to the continuous attempts to restore connection to the Access Point/Router.

2. BP SE SENSOR BUILTIN PROBE

The BP SE Sensor is designed to be positioned directly inside the showcases,  tted using its own fastening bracket. The rear features metal shielding that, combined with the thermal insulation inside the shell, prevents the formation of frost at the rear of the sensor, and consequently better thermal insulation from the wall.

• Instant temperature measurement performed every minute.

• Measurement  ltering with weighted average based on parameter setting

for product temperature simulation.

• Data transmission at settable intervals, in minutes (the parameter a ects

battery life).

• Monitoring of temperature thresholds for high temperature (HACCP) or low

temperature (product freezing) alarm signals.

• Automatic mode with preset parameters according to the showcase/

display case (normal, low temperature or open shelf).

• Local mode for Clean showcase status signal. Activating the Clean button

disables the high temperature alarms.

• TimeStamp for recording the instant measurement, expressed in hh:mm.

than 30=excellent);

• Temperature alarm status related to the high and low thresholds.

2.2 Sensor con guration

The sensor is supplied with the address ID set to 127 and cannot be used with the default ID; the range of available addresses is from 16 to 126. To assign the ID use the rTM SE handheld accessory. For details on the address assignment procedure see the instructions in the chapter on the rTM SE handheld further on. In emergency situations a new ID can be assigned (limited to the range from 16 to 99) using a magnet (e.g. magnetic screwdriver Carel code 0000000722), as follows:

1. Position the magnet on SW1, holding it in position when the green LED

comes on;

2. The following will be shown in sequence:

- Green LED ON for 2 to 3s then OFF for 3 to 4s;

- Orange LED ON for 3 to 4s;

- Remove the magnet when the LED switches o ;

- After a few moments the LED comes on yellow for 1s. This indicates

that programming procedure is active (if no actions are performed, programming mode ends after 4/5 s, indicated by a double yellow  ash, leaving all the settings unchanged);

3. Move the Clean switch SW2 up and down a number of times equal to the

tens of the serial address being set (e.g. 10, once – 50,  ve times). Each time switch SW2 is moved up the red LED comes on for 1 s, (con rming stimulation);

4. Subsequently use the magnet to stimulate switch SW1 a number of times

equal to the units (e.g. 1, once – 5,  ve times). Each time the magnet moves over the switch the green LED comes on for 1 s (con rming stimulation). The order is not important (tens or units  rst);

5. After 4/5 s the sensor exits the procedure, with the yellow LED  ashing

twice (indicating the end of serial address setting mode);

6. Subsequently the sensor shows the serial address using a sequence of

 ashes repeated cyclically three times. To read the codes, see the chapter “Display sensor serial ID” further on.

7. Moving switch SW2 up interrupts the cycle;

The sensor address has been set and it’s ready to be bound to an Access Point. The procedure can be performed before or after binding to the Access Point.

Make sure not to assign duplicate serial addresses, also considering other devices in the network. For further information and explanations on the procedure, see the rTM SE system installation guide.

Binding procedure

Binding is a special procedure used to associate the sensors with the Access Point. Once completed, the sensors will send the temperature data measure wirelessly only to the Access Point de ned as its parent. Following this, the Access Point will forward the data to the Modbus® RTU RS485 serial network. The binding procedure requires the activation of the Access Point wireless network and activation of the con guration switch SW1 using a magnet (see the  gure), done by passing the special magnet over magnetic switch SW1 for a few seconds. The LEDs will come on in sequence: green (1s), yellow (4 to 5s), green (6 to 10s). If at the end of the sequence the red LED  ashes brie y (1 to 2s), binding with the Access Point has failed. If the operation is successful, successively activating switch SW1 will start manual data transmission, signalled by the green LED  ashing quickly twice. If the automatic or manual data transmission fails, the red LED will  ash brie y after the green LED comes on. After this operation the sensor will start sending data on the temperature measured, in the time interval set by parameter. Check that the LED comes on for a few seconds at regular intervals, based on the transmission time set for parameter (HR_01 TRANS_CYCLE). When the operation has ended close the wireless network on the Access Point. The wireless network can be opened and closed using the rTM SE handheld accessory.

Display sensor serial ID

To check the sensor serial address, proceed as follows:

• Move switch SW2 (CLEAN) up, stimulate SW1;

• The LED starts  ashing in sequence. Count the number of the  ashes to

calculate the hundreds (Yellow), tens (Green) and units (Red). Removing the magnet or lowering the button exits the display probe serial address procedure.

• Move switch SW2 back down.

Tab. 2.b

Resetting the sensor (maintaining the serial address)

The reset procedure is required when the sensor needs to be moved and associated with another wireless network (di erent Access Point). This operation may be required to recon gure the sensor in a di erent wireless network. The value of the serial address remains the same, and after a new binding operation the sensor is reactivated in the wireless network. To reset the sensor, proceed as follows:

1. Place the magnet near magnetic switch SW1 (the green LED will come on);

2. Hold the magnet in place until the green LED goes o and the yellow LED

comes on (after approx. 6 to 10 sec.);

3. When the yellow LED comes on, move the magnet immediately away

from the sensor and check that the LED  ashes quickly before going o (RESET COMPLETE).

To check that the sensor has been reset, proceed as follows:

1. Make sure the Access Point wireless network is closed (L1  ashing slowly

1s);

2. Stimulate switch SW1 on the sensor with the magnet;

3. Check that LEDs come on in the following sequence:

- green LED (1 s);

- yellow LED (4 to 5 s);

- green LED (15 s);

- red LED (1 s);

Make sure that there are no sensors with the same serial address in the new network. If this is the case, assign a new serial address.

ENG

“Wireless probes” +0300030EN - rel. 1.0 - 16.07.2010

RESET sensor and assign default serial address (=127)

To restore the sensor serial address to the default value, proceed as follows:

1. Place the magnet near magnetic switch SW1, the green LED will come on.

2. Hold the magnet in position until the green LED goes o and the yellow

LED comes on (after approx. 6 to 10 s);

3. Immediately remove the magnet from the sensor and at the same time

move the CLEAN switch (SW2) up, making sure the yellow LED  ashes a few times.

4. Move the CLEAN switch to the OFF position and make sure the yellow LED

completes a rapid sequence of  ashes (RESET COMPLETE);

Otherwise repeat the procedure.

To check that the sensor has e ectively been reset, proceed as follows:

1. Make sure the Access Point wireless network is closed (L1  ashing slowly

1 s);

2. Stimulate the switch SW1 with the magnet;

3. Check that LEDs come on in the following sequence:

- green LED (1 sec.);

- yellow LED (4 to 5 sec.);

- green LED (15 sec.);

- red LED (1 sec.);

Completing the reset procedure and assigning the default serial address returns the sensors to the same status as a new device. To assign a new address, repeat the serial address assignment procedure.

Note:

1. The sensor can only be reset if it has already been bound to an Access

Point.

2. Note that, after resetting the sensor, the number of devices set for the Access

Point remains unchanged. Realignment will occur after a maximum of around 2 hours.

Note: the LED is two-colour, red and green, which becomes yellow when both LEDs are on at the same time. There may be di erent shades of yellow due to di erent tolerance in the brightness of the red and green LEDs.

2.3 Sensor activation

When the sensor is put in SLEEP mode using the rTM SE handheld during the procedure to assign the serial address (no transmission-minimum power consumption), the sensor is e ectively in standby; nothing is transmitted until movement of the CLEAN switch is activated (sleep status). Activation is not reversible, and the sensor will send the temperature measured every 16 min (default value) if the Access Point that the sensor has been bound to is switched on. To exit sleep mode, proceed as follows:

• Power up the Access Point;

• Move the CLEAN switch to the ON position (SW2);

• Make sure the red LED comes on for a few seconds.;

• When the red LED comes on immediately the CLEAN switch to the OFF

position;

• The LED on the sensor remains on until it has connected to the Access Point.

If the operation fails, the sensor returns to sleep mode, if however it’s successful normal operation will resume, with data being sent every 16 min. Check operation by stimulating the sensor.

Resetting the sensor in sleep mode

If the sensor needs to be reset when in sleep mode (Access Point network parameters forgotten), proceed as follows:

• Move the CLEAN switch to the ON position (SW2);

• Wait for the red LED to come on;

• Stimulate SW1 continuously while the red LED remains on.

• Keep SW1 stimulated until the LED  ashes (yellow) ;

• Remove the magnet from SW1 and move switch SW2 back down.

• Reset completed.

Parameters and functions

The BP wireless sensor reads the temperature and manages the associated alarms at one minute intervals. The data is then transmitted at the intervals set by parameter, according to the application and the expected battery life. The sensors work most of the time in low power mode, so as to save battery power. They are activated to make the measurements and send the data at the preset time. Activate switch SW1 to send the sensor data manually, or check the connection. The CLEAN button is used to set cleaning status or deactivate the showcase, thus disabling the high temperature alarms. When returning from CLEAN mode, the high temperature alarms are disabled for a time equivalent to the auto-con guration cycle (AUTO_DELAY).

ENG

“Wireless probes” +0300030EN - rel. 1.0 - 16.07.2010

The sensor takes individual instant temperature measurements, however can also provide a weighted average, used to better approximate the product temperature. The logic for the alarms and all the other functions depends on the instant temperature measurement. Wireless communication is activated automatically in the following situations:

• moving the CLEAN mode switch (SW2);

• stimulating the magnetic switch (SW1).

In all other cases, data transmission is de ned by the set transmission cycle.

Note:

• The temperature measurement, with the update of the instant and average

values, is performed at 1 minute intervals. Important: the value is displayed on the supervisor after the set sensor transmission time . The average temperature value is calculated using the following formula:

Temp_AVG = (Temp_AVG-1 * (M - 1) + Temp_Ist) / M

Where:

• Temp_AVG-1 Previous average temperature value

• Temp_Ist Instant temperature measurement

• M Average weight (= AVERAGE_PARAM)

The average function also introduces an average measurement delay with a time constant equal to the average weight value (in minutes).

Automatic con guration procedure

The automatic recognition procedure is used to recognise the type of showcase and consequently con gure the parameters for the showcase that the sensor is installed on. The automatic recognition cycle is activated (if enabled by EN_AUTO_CONF):

• When the temperature falls below the threshold MODE_AUTO_TRESH;

• When returning from CLEAN mode, closing the switch;

• When a previous cycle is completed.

When the AUTO_DELAY time has elapsed, if the following conditions are true:

• Final temperature rise less than 1°C/h;

• Final temperature within a  xed band of temperatures for the various types

of showcase:

- medium temp. showcases = from -2°C to + 6°C

- low temp. showcases = less than -10°C.

The MODE_PARAM parameter is given the new value corresponding to the type of showcase and the associated values for the alarm thresholds, alarm delay and average weight are loaded;

Note:

• In the event of increases in temperature for low temperature showcases,

the recognition procedure is disabled for 3 times the value of AUTO_DELAY, to avoid false recognitions.

• The temperature alarms are always enabled, if MODE_PARAM and

consequently the associated parameters are changed, the alarm logic depends on the new parameters.

• The parameters associated with each mode (0-3) are saved separately and

permanently, and are loaded automatically when the mode is changed.

• The values of the parameters associated with the mode must be set (by the

supervisor) making sure that MODE_PARAM does not change, otherwise the values transferred may be ignored.

3. EP SE, SA, SI SENSORS AND CI PULSE COUNTER

3.1 Parameters and functions

The wireless devices read the temperature and manage the associated alarms at intervals set by the transmission time parameter, according to the application and the expected battery life. The sensors work most of the time in low power mode, so as to save battery power. Press the button or stimulate the magnetic switch to send the sensor data manually, or check the connection.

3.2 Description of the acquisition process

The devices acquire all the values before sending their status to the Access Point. Consequently, the device sampling interval is equal to the transmission time.

3.3 Device con guration

Select the desired network address using the 8 dipswitches (0=OFF; 1=ON) as shown in the table. The possible sensor addresses are from 16 to 126.

3.4 Binding procedure

Binding is a special procedure used to associate the sensors with the Access Point. Once completed, the sensors will send the temperature data measure wirelessly only to the Access Point de ned as its parent. Following this, the Access Point will forward the data to the Modbus® RTU RS485 serial network. Before performing this operation, make sure that the sensor serial address has been set. After having opened the domain on the Access Point (see the instructions in the chapter on the Access Point), proceed as follows on the sensor: Remove the protection from the contact on the battery to power up the device; Check that the LED comes on for a few seconds with brief  ashes. Press the button once or activate the magnetic switch. Pressing it again activates a procedure to check the quality of the wireless signal (see the chapter “Analysing wireless signal quality”); LED L1 on the sensor remains on until connection to the Access Point is complete,  ashing for around 10s, then L1, L2 and L3  ash together for a few seconds (wireless network connection). The procedure for analysing wireless signal quality then starts for around 1 minute. The following come on in sequence:

1. L1 Indicates wireless transmission has occurred;

2. L1-L2 Indicates the signal has been received by the Access Point;

3. L3  ashes from 1 to 3 times, based on the quality of the wireless signal;

- 1  ash, wireless connection with minimum signal strength;

- 2  ashes, wireless connection with medium signal strength;

- 3  ashes, wireless connection with excellent signal strength;

Button T1 is connected in parallel with the magnetic switch. The case does not need to be opened to stimulate the sensor for communication

Note: if LED L1  ashes once instead of remaining on, it means that the sensor has already been bound to an Access Point. In this case, reset the sensor (see Resetting the devices) The Access Point shows that connection has been made by LED L3 coming on for around 1s., even if another node in the network is sending a message. Check the con guration: the sensor will be correctly bound if whenever the button is pressed or the magnetic switch is activated, the LEDs come on for a 1 min sequence.

• L1, on for 1s;

• L1-L2, on for 1s;

• L3,  ashes from 1 to 3 times, based on the quality of the wireless signal;

- 1  ash, wireless connection with minimum signal strength;

- 2  ashes, wireless connection with medium signal strength;

- 3  ashes, wireless connection with excellent signal strength;

For the EP SE Sensor, in normal operation LED L1  ashes for 1s every 20s. In general, for the other devices, the LED comes on whenever data is sent, and consequently based on the device transmission time.

Important: the sensor binding operation may fail if:

- the distances are high and/or there is infrastructure that does not allow communication between the devices (see the example of sensor S2 in Figure

4.c);

- the maximum limit of sensors allowed for the Access Point has been reached (max 30). In this case, an additional Router-Bridge is needed for up to a maximum of 60 sensors.

3.5 Resetting the sensor (unbinding)

The reset procedure is required when the sensor needs to be moved and associated with another wireless network (di erent Access Point). This operation may be required to recon gure the sensor in a di erent wireless network. The value of the serial address remains the same, unless the con guration dipswitches are moved. After a new binding operation the sensor is reactivated in the wireless network. To reset the EP SE Sensor, proceed as follows:

1. Remove the battery (press the button to discharge any residual energy in

the circuit) and replace the battery in its socket (LEDs L1, L2, L3 come on at the same time, then  ash quickly and switch o ).

2. Immediately after the LED have switched o (within a few seconds) press

button T1 until the pairs of LEDs L1-L3 and L2  ash alternately.

3. Release the button. LEDs L1, L2, L3 will  ash brie y and then switch o .

To make sure the sensor has e ectively been reset:

1. Make sure the Access Point wireless network is closed (L1  ashes slowly

1s).

2. Press button T1 on the sensor and make sure LED L1 comes on and

remains on for around 20 sec.

WARNING: The sensor has been unbound (reset) and maintains the same network address assigned. To change the address, remove the battery, move dipswitches 1 to 8, and replace the battery.

Note:

1. The sensor can only be reset if it has already been associated with an

Access Point;

2. Resetting the sensor does not delete the space reserved inside the Access

Point, which will continue to maintain the data saved inside. Note that, after resetting the sensor, the number of devices set for the Access Point remains unchanged. Realignment will occur after a maximum of around 2 hours.

Important: pay careful attention to avoid duplicate assignment of network

serial addresses, so as to avoid overlapping temperature values.

The sensor is supplied with the battery already  tted, and with the positive pole insulated by a protective  lm; this must be removed after assigning the network serial address.

3.6 General warnings

When replacing the battery, strictly observe the following instructions. The battery may explode if replaced with another of an incorrect type. Dispose of the used batteries according to the standards in force; Install the sensor with the cable gland facing downwards;

Replacing the battery

Remove the cover, remove the battery, and replace with another of the same type. Close the cover again.

4. EP SENSOR EXTERNAL PROBE

The EP SE Sensor is designed to be  tted inside showcases or cold rooms, and can house two external passive NTC temperature probes 10K@25°C (Beta(25/85) = 3435K) and two digital inputs to be used to monitor door and defrost status, or used as generic inputs.

Fig. 4.a

4.1 Functions implemented

• Instant temperature measurement performed every minute, probe 1;

• Instant temperature measurement performed every minute, probe 2;

• Data transmission at a settable interval in minutes (this a ects battery life);

• Monitoring of temperature thresholds for high temperature (HACCP) or low

temperature (product freezing) alarm signals.

Main variables available to the supervisory system

• Probe 1 temperature;

• Probe 2 temperature;

• Battery level in mV ;

• Wireless signal level in dBm +100 (8 = low signal, 15 to 30 = medium signal,

greater than 30 excellent).

• Temperature alarm status related to the high and low thresholds.

• Data transmission interval;

• Enable high temperature alarm;

• TimeStamp for recording the instant measurement, expressed in hh:mm;

4.2 Parameters and functions

The EP SE wireless sensors read the temperature and manage the associated alarms at intervals set by the transmission time parameter, according to the application and the expected battery life. The sensors work most of the time in low power mode, so as to save battery power. Press the button on the sensor to send the sensor data manually, or check the connection. The main parameters and functions of the sensor are:

-Data transmission activation:

-Wireless transmission is activated in the following conditions:

• Change in status of the digital inputs, door and defrost;

• Temperature probe fault alarms;

• Brie y pressing the button. In all other cases, data transmission is de ned by the set transmission time.

Logical state of DOOR_POL and DEFROST_POL variables

The following table shows the logical state of the input based on the electrical state of the contact (open or closed).

Fig. 4.a

The  gure shows the high temperature alarm function:

1. when the threshold is exceeded, the alarm is signalled only if this persists

for a time greater than the delay set;

2. if the temperature returns within the threshold before the delay time, the

accumulated count is reset;

3. the alarm is reset instantly when the temperature returns within the threshold.

Enabling and disabling the digital inputs

Management of the door and defrost inputs can be enabled or disabled using EN_DI_DOOR for the door input and EN_DI_DEFROST for the defrost input. If not enabled, the inputs are inactive (0). Even when disabled, however, the logical state of the digital inputs can be identi ed by reading the value of IN_1_STATUS for IN_1 (1=Active, 0=Not active) and IN_2_STATUS for input IN_2 (1=Active, 0=Not active). By default the door and defrost inputs are enabled.

The high temperature alarm is activated after the delay if the door input is active. For correct operation of the temperature alarm signals, the status of the door and defrost must always be read as inactive, even if the two inputs are not used. To return both to normal conditions, the value of the two polarity states can be set to 1 for the door (DOOR_POL) and defrost (DEFROST_POL), or alternatively the two inputs can be jumpered if not used.

Enable and disabling the analogue inputs

EN_NTC_1 and EN_NTC_2 enable and disable the probe inputs. The probe inputs can be enabled and disabled using parameters EN_NTC_1 and EN_ NTC_2 respectively. If a probe input is disabled, the temperature reading is equal to 0°C; in this event, the probe alarm fault is not managed and remains constantly inactive (0). By default the probe inputs are enabled.

8.1 Main functions

• Manual opening/closing of the wireless domain (button). Via software or

rTM SE handheld for binding the devices (sensors or Routers);

• Automatic selection of the channel wireless to be used.

• Count the number of sensors connected;

8.2 Parameters and functions

The Access Point manages the wireless network and the wireless connection of all the units, making these accessible to the supervisory system via the Modbus RS485 serial connection. For all the sensors managed directly, it stores a copy of all the parameters and variables, which are updated every time data is transmitted via the wireless connection. The Access Point makes the data for all the peripherals available to the supervisor at all times, even if wireless transmission is performed at set intervals.

Setting the operating mode

Parameter HR_03 used to set the Access Point operating mode. The table below summarises the various operating modes:

Value Description Notes

HR_03 = 21 Communication with

Router-Bridge disabled

(default)

HR_03 = 17 Communication with

Router-Bridge enabled

Filters should be con gured to set the min and max addresses of the devices connected via Router-Bridge (HR_11 and HR_12);

8.3 Con guration

The following chapter describes the procedure for setting the address, con guration and connection of the devices, so as to create a wireless domain that is connectable to a controller via the Modbus RTU protocol. A fundamental step is commissioning, which involves the unique identi cation of each device by:

• Assigning a unique network address to each device;

• Binding of the devices to a domain so that the devices can communicate

with each other. All the other devices cannot communicate even if they are reached by the wireless signal.

Security of communication over the network is guaranteed by the 128 bit encryption key (AES) written inside the program on each device. In normal operation, only the serial address is used, which is also unique within the network and is su cient to identify each unit.

WARNING!

Two units cannot have the same serial address. Therefore pay careful attention when assigning the network addresses to the sensors and Access Points so that there are no devices with the same serial address, also considering any instruments connected to the remote wired network via the Bridge. This would create con icts and interference in the storing of temperature data.

8.4 Setting the address

This is a fundamental phase in setting up the system, and allows each device to be identi ed uniquely by assigning a unique network address to each device (Modbus® network address).

Access Point

• Assign the CAREL network address and baud rate using 4 dipswitches as

shown in the following table;

• Power up the Access Point;

• Check that the LED 1 is always on and the others are o . If the LEDs are not

in this status, reset the Access Point (see Resetting the devices).

Creating the network and selecting the wireless communication channel

The wireless system requires of use a transmission channel for the communication of the wireless messages between the various devices. The best communication channel for the environment in question is automatically selected by the Access Point, using the following procedure:

Power up the Access Point (LED 1 must be on steady);

1 2 3

Press the button and check the activation sequence:

The Access Point is ready for use, the wireless network has been initialised. The transmission channel has been selected and will be sent to the Routers and sensors during the binding phase.

Important:

• If the sequence does not occur as indicated, reset the device (see Resetting

the device);

• If the Access Point is reset, all the instruments bound to it will be

disconnected and will need to be bound again.

8.5 Binding procedure

The logical connection between the Access Point and the wireless devices is called binding. This operation must be performed after setting the addresses and selecting the communication channel.

Power up the Access Point and check that LED 1  ashes slowly (1s).

Note: all devices previously bound will be removed from the Access Point/ Router (no. devices connected=0).

8.7 Serial communication parameters

The Access Point data and the data of all the devices making up the network can be accessed via ModBus-RTU serial communication protocol. The serial communication parameters are as follows:

Speed: 9600 Bps (DIP4=o ) / 19200Bps (DIP4=on) Data bits: 8 Parit y: None Stop bits: 2 Flow control: None

Given the nature of the Modbus protocol, the data for all the devices, including the Gateway, are divided into four memory areas:

IRxx  InputRegister (16 bit read-only variables) ISxx  InputStatus (1 bit read-only variables) HRxx  HoldingRegister (16 bit variables, generally non-volatile) CSxx  CoilStatus (1 bit variables)

The codes of the functions implemented in the Access Point are as follows: 01 - READ COIL STATUS 02 - READ INPUT STATUS 03 - READ HOLDING REGISTER 04 - READ INPUT REGISTER 05 - FORCE SINGLE COIL 06 - PRESET SINGLE

9.1 Parameters and functions

For each Router in the network, the information listed in the table can be identi ed from the noti cation messages sent by the Router to the Access Point, updated at intervals established by parameter HR_05 on the Access Point (default 20s).

9.2 Binding the Router to the Access Point

• Open the domain on the Access Point (press button T1 once).

• Power up the Router.

• The button on the Router does not need to be pressed, if the device is free

the procedure is activated automatically.

• All the LEDs come on steady.

• The Router searches for an Access Point to connect to (all the LEDs  ash

every 20s).

• Binding is successfully completed when only LED L1 remains on  ashing,

the Router is now connected to the Access Point.

• The Router address is set automatically and sequentially by the Access Point

when it’s added to the network, assigning the network addresses from 200 to 247 for a maximum of 48 devices. This is valid for all Routers (including the Router-Bridge and EP1 Router-Sensor, etc.). A maximum of 60 Routers can be added.

• The commissioning procedure is now complete and the system is ready to

communicate data.

Tab. 9.a

NOTE: the binding operation on the Router may fail if:

• Distances are excessive;

• Infrastructure is present that prevents communication between the devices;

Each sensor installed should be visible to at least 2 devices, either Access Point or Router. In the event of faults on the Router or additional barriers that block the wireless signal, the sensor will  nd an alternative route to communicate with the Access Point.

10. ROUTERS WITH OTHER INTEGRATED FUNCTIONS

10.2 RB Router-Bridge

The Router-Bridge is used to connect a local Modbus RTU network of Carel or third party devices when needing to supervise instruments via a wireless network. The address setting and reset procedures are the same as described for the Router.

The following approved devices can be connected to the local network::

• Gavazzi CPT-DIN / WM14;

• Gavazzi WM14;

• IR33 Modbus® IR33C0HB0M.

The devices described above have been checked with the PVPRO supervisor as shown below. Operation of the devices outside of the limits indicated or with others supervisors is not guaranteed.

1. Limits in message sizes. Responses must not exceed 52 bytes; this implies

that no more than 26 registers (holding registers or input registers) can be read with one single message;

2. Query frequency. The time interval between receiving a response and the

following query must not be less than one second;

3. Communication timeout. The time interval between two consecutive queries

before a response is received must not be less than 3 seconds. This means a communication timeout of at least 3 seconds.

Dipswitches 1 to 4 are used to set the operating features of the local Modbus RS485 serial connection.

Installation example of the Router-Bridge and EP1 Router-Sensor in a network with other wireless devices

Fig. 10.a

Other Router devices are available that integrate the following functions:

• EP1 Router-Sensor (with two analogue and two digital inputs, the same

operation as the EP SE Sensor battery version);

• RB Router-Bridge (to extend a Modbus RS485 local network, connecting

other devices);

• RA Router-Actuator (I/O module with thermostat function);

• RC Router-Pulse Counter (same operation as the CI Pulse Counter battery

version); The address setting and reset procedures as the same as described for the Router. The dipswitches on the device are used to set the address for the integrated functions. Consequently each device has two network addresses: the Router address assigned automatically by the Access Point, and the device address selected by dipswitch (excluding the Router-Bridge). For complete supervision of the devices, both network addresses must be monitored;

10.1 EP1 Router-Sensor

The EP1 Router-Sensor has 2 probe inputs and 2 digital inputs, and features the same functions and same parameters as the EP SE Sensor battery version. It is used in all applications requiring monitoring of digital inputs that change frequently and where the life of the battery version would be too short (each opening and closing of the digital contact causes wireless communication to update the parameters). For the features, operating modes and supervision, see this manual under the section on the EP SE Sensor.

ENG

“Wireless probes” +0300030EN - rel. 1.0 - 16.07.2010

10.3 RA Router-Actuator

The Router-Actuator is a device featuring:

• 1 NTC probe input 10K@25°C

• 2 two digital inputs;

• 2 digital outputs;

The device implements a thermostat function with programmable heating/

cooling mode, relay outputs and alarm management based on set thresholds.

Alternatively, the control function can be disabled and inputs and outputs

managed directly by the supervisor or via Modbus® controller.

10.4 Functions implemented

Analogue temperature input management

The device acquires the temperature via the analogue input using an external

probe with sampling once a second (probe 10K@25°C Beta=3435K). The

operating range is -50T90°C. When the temperature values are outside of

these limits, the device signals an alarm:

• +100  probe input short-circuited;

• -50  probe input open;

Temperature alarm management

The device compares the temperature measured by the reference probe

against the parameters that de ne the alarm limits.

There are no delays in activating the alarm signal; as soon as the acquired value

is higher than the maximum limit or lower than the minimum limit the alarm

is activated.

If Temperature > High temperature limit --> high temp. alarm =1

If Temperature ≤ High temperature limit --> high temp. alarm =0

If Temperature < Low temperature limit --> low temp. alarm =1

If Temperature ≥ Low temperature limit --> low temp. alarm =0

If the probe input is short-circuited (signal equal to +100.0°C), as well as the

probe fault alarm, the high temperature alarm is also activated.

If the probe input is open (signal equal to -50.0°C), as well as the probe fault

alarm, the low temperature alarm is also activated.

Control management (digital outputs)

The control process is managed based on the Control mode parameter.

Mode =0

Control is disabled and both relays are deactivated.

Mode =1 (Cool)

Control is performed as follows:

High threshold = Set Point + Hysteresis/2

Low threshold = Set Point - Hysteresis/2

If Temperature > High threshold --> Relay 1 On ; Relay 2 O

If Temperature < Low threshold --> Relay 1 O ; Relay 2 On

Control in the event of probe faults

In the event of a probe fault control is disabled and both relays are deactivated.

Mode =3 (Manual)

In this mode the state of the relay is controlled by CS_01 and CS_02.

Mode =4 (Manual with button input)

In the same way as for mode 3, the relays are controlled by CoilStatus[1] and CoilStatus[2]. In addition, the state of relay 1 is also controlled by a button connected to digital input IN_1 and relay 2 by a button connected to digital input IN_2. Operating the button reverses the logic of the related output.

Mode =5 (Manual with switch input)

10.5 RC Router-Pulse Counter

The RC Router-Pulse Counter has 2 digital inputs and 2 probe inputs, and the same functions and same parameters as the CI Pulse Counter battery version. It is used in all applications that require monitoring of electricity, water and gas consumption when the digital inputs have a high switching frequency (the life of the battery version would be too short, as each opening and closing of the digital contact causes wireless communication to update the parameters). The data are saved to static memory every 6 hours, in the same way as the battery version, and in the event of power failures the data is retained in the memory without loss.

For the features, operating modes and supervision, see this manual under the section on the CI Pulse Counter..

10.11 General warnings

Fasten the device to the wall with the cable gland facing downwards; Tighten the antenna in its housing (4), and position it vertically to the  oor; Connect the power supply to the terminal (1), ensuring the polarity indicated for DC power supply (12 to 24 Vac/dc version). A 12 Vac transformer is recommended for the device 12-24 Vac versions. For correct operation the system must be powered at all times, in the event of power failures there may be a unit reset time (OFFLINE) based on the data transmission cycle.

IMPORTANT:

If the same power supply is shared by more than one unit, connect the same wire from the transformer to the power supply “-” terminal (1).

ENG

“Wireless probes” +0300030EN - rel. 1.0 - 16.07.2010

11.3 Wiring

To wire the serial connection to the Access Point or Router-Bridge local RS485 network, use 3-wire shielded cable. To ensure IP55 protection on the case, use a 5-wire cable, and relay the serial and power supply connections through an external junction box with terminal block. The maximum wire size for the terminals is 1.5 mm2. The maximum outside diameter of the cable must not exceed 8 mm, to allow it to pass through the cable gland.

Features of the serial connection cable

For connection to the Access Point, the cable used must have the following characteristics: Twisted pair; Shielded, preferably with earth wire; Size AWG20 (diam. 0.7-0.8 mm; area 0.39-0.5 mm); Make sure that the cable shield is connected to EARTH on the supervisor connection side, and that the polarity of the connection is observed on all the units connected. The shield is normally connected to the reference on all the units.

Also pay careful attention when connecting the local network to the RouterBridge, when using controllers connected in a local Modbus® RS485 network.

11. GENERAL NOTES

11.1 Notes for correct installation

• To ensure correct operation of the ZigBee wireless system, the best possible

connection must be guaranteed between the Access Point and the Router.

• The Router should preferably be installed at a height of around 2 to 3 m

from the  oor, not in contact with large metallic objects (air ducting etc.), so as to avoid the Router-Access Point connection being a ected by obstacles such as cabinets, showcases, moving people, and where possible in direct line of sight with the other devices.

• Make sure that the path between the Router and the Access Point does not

include metallic  re doors or large metallic obstacles (elevator compartment etc.) which may disturb the connection.

• When positioning the devices, check that the sensors have at least two

wireless routes to the Access Point; that is, they can be seen by at least two Routers or one Router and the Access Point, and that the wireless signal levels, both in and out, are good. Remember that wireless devices are signi cantly a ected by changing environmental conditions, unlike wired connections, and therefore each sensor should be able to reach the Access Point via at least two devices connected at the same wireless network, which may be an Access Point and Router, or two Routers. It’s also recommended to set a delay on the supervisor (around 1 hour) for notifying alarm signals, so as to avoid false sensor o ine warnings;

• Fasten the Access Point/Router in position, considering that as the device

being installed is a radio device, the following simple rules must be observed:

• The e ciency of radio transmission is reduced when there are obstacles,

metal shelving or other objects that may block the reception of the wireless signals;

• If the product is wall-mounted, fasten it to a masonry wall rather than a

metal wall, to improve the range of the signal;

• Like all radio equipment, avoid installing the Access Point near other

electronic appliances, so as to avoid interference;

• Connect the RS485 network to the terminal respecting the polarity.

• For correct operation the system must be powered at all times, in the event

of power failures there may be a unit reset time (OFFLINE) based on the data transmission cycle;

• Do not install the instruments in environments with the following

characteristics:

• Strong vibrations or knocks;

• Exposure to water sprays;

• Exposure to direct sunlight or the elements in general;

If the devices are used in a way that is not described by the manufacturer, the speci ed level of protection may be a ected.

11.2 Power supply connection

The 12-24 Vac/dc Access Point and Router can be powered using the CAREL 230/12 Vac 3 VA plug-in transformer code TRASP3E120, or electrical panel transformer code TRADR4W012, or any other 12 Vac 2 VA transformer.

For 12/24 Vac/dc versions, the maximum wire size for the terminals is 1.5 mm2.

12. RTM SE HANDHELD

12.1 General Features

The rTM SE ZigBee handheld is a very useful device for the installation, control and maintenance of networks of rTM SE system wireless devices. It is not needed however for normal operation of the wireless network devices (sensors, Access Points, Routers).

For a limited operating period inside the network, the handheld represents a Router-like node on which the normal wireless tra c relaying functions are disabled. Its function is essentially to identify the wireless signal level in the area where the Sensor or Router-Bridge is being installed, so as ensure these are reached by the wireless signal, checking the signal level and how many receiving devices can be connected. In other words it identi es whether the position chosen for the installation of a new Sensor or Router is suitably covered by the wireless signal in question. The rTM SE handheld also provides the following functions:

• Open and close the wireless network on the Access Point in order to bind

other sensors, without having to press the local button on the Access Point or access it via the supervisor;

• Reset Routers and Access Points associated with the wireless network;

• Set the address of BP Sensors after binding these to an Access Point;

Security of these operations is guaranteed by the network password that can be set on the rTM SE handheld.

It is consequently a tool that signi cantly simpli es the installation of the rTM SE system.

Warning. Due to the reduced space available on the rTM SE handheld display, only the last 4 digits (LSB) of the MAC ADDRESS are displayed.

During this operation, the rTM SE handheld sends a wireless message to all the Router nodes in its operating range at regular 3 second intervals (unit range broadcast). This event is highlighted by the “PING” message at the top of the display. The Router devices that receive the message respond with a message sent to the rTM SE handheld containing their address. The messages received by the rTM SE handheld are used to constantly update the values displayed.

The Ping Test lasts four minutes, after which the main menu is automatically displayed. Alternatively, the Ping Test can be ended by pressing the “Left” button. Pressing any other button repeats transmission of the wireless message.

The three vertical lines used to represent the RSSI indicate, from left to right respectively, a value of -90dB, -80dB, -60dB (for the supervisor these would be 10 dB, 20 dB, 40 dB) The intermediate line indicating -80dB represents the threshold value below which the signal is not considered su cient and above which it’s considered good.

Note: The asterisk on the left next to the MAC ADDRESS indicates the coordinator node. Either the device MAC ADDRESS or Modbus address can be displayed. To change the display mode, see the “View Mode” menu under “Commands”.

12.9 Network commands

The “Commands” menu is used to execute commands and make settings inside the network that the rTM SE handheld is connected to. The following commands are available:

1. Address display setting (MAC ADDRESS / Modbus® address);

2. Open/close the network (for binding new devices);

3. Unbind a Router;

12.13 Password entry menu

The functions for opening the network and unbinding the Routers require a numerical code in order to be accessed. This numerical code must be the same as the Access Point password. The password is stored on the Access Point (HoldingRegister[13] on the Access Point, see the related documents). Before prompting to enter the code, the handheld device communicates with the Access Point to identify the password. For this reason, the Access Point must be on and have a compatible  rmware version ( rmware version 8.1 and higher).

The up/down buttons increase the selected value. The left/right buttons move the cursor. To conrm the value, move the cursor to the right of the unit or press the button on the right immediately under the display. (“Function 2” button)

12.20 ZigBee handheld signal meter shutdown

The handheld wireless signal level meter automatically goes into low power mode after four minutes of inactivity to extend battery life. Low power mode can be activated manually by pressing the “O ” button. In low power mode, pressing any button returns the device to the previous status.

Note: during the Ping Test, the O button only switches the device to low power mode for a few seconds.

Note: If the handheld wireless signal level meter is not used for an extended period (a few weeks) the batteries should be removed.

Battery Life

The estimated battery life is 26 hours of continuous operation of the device.

(power consumption 12J/minute, battery power 19000J, --> 19000/12 = 1580 min = 26.3 hours)

12.21 Notes on operation

The ZigBee handheld wireless signal level meter has been designed for use when installing a new network of devices. It identi es the number of Routers and Access Points that are accessible from the position where the ping test is performed. The ping test also provides information on the strength of the wireless signal on the Routers and Access Points in the vicinity, highlighting whether the connections are good or have a low signal.

The installation guidelines require each Router to be within radio range of at least two other Routers. The same applies to the sensors; indeed, each sensor should be connected with a good signal to at least two di erent Router devices (or Access Points).

Where installation restrictions limit the optimum positioning of the Router and sensors, the handheld wireless signal level meter can help identify the best position for the additional Routers that must be installed in order to cover the areas not reached by the wireless signal.

14. ZCONFIG PROGRAM

System requirements

Z-Con g runs on a Personal Computer with the Microsoft Windows 98, 2000, XP or XP SP2 operating system. The program’s limited use of memory resources (hard disk-RAM) means it can be installed and run on any recent PC. Installation of the program requires installation of the DotNetFramework version 2.0

Starting the program

When starting Z-Con g, the following screen is displayed:

Fig. 14.a

Main program windows

The program is divided into three main windows, selected using the buttons at the top left of the program window

Fig. 14.b

System Settings:

Window containing the settings for the serial communication port, network settings and graphics settings under the “Graphics Network” window.

Data Table:

This window shows the summary table of past and current wireless communication between the Router-Sni er and the devices in the network this is connected to.

Graphics Network:

Window showing a graph of connection levels between the devices in the network.

ENG

“Wireless probes” +0300030EN - rel. 1.0 - 16.07.2010

“System Settings” window

This window features several frames:

Opens the serial port for communication with the Router-Sni er. The port corresponding to the Router-Sni er device must be selected. if there are several ports and it’s not clear which one the Router-Sni er is connected to, unplug the device from the Personal Computer; then select the Refresh button, reconnect the Router-Sni er and then select Refresh again. The newly connected Router-Sni er will be displayed in the list and will be easy to identify.

Fig. 14.c

Network Parameters

The network parameters consist of the Transmission channel (16 possible values, from 11 to 26), the network PanID (network address) and the extended PanID. The network parameters must be identical to the network being monitored. To identify the parameters of the desired network, check the data in the installation  le or on the supervisor. When opening the serial connection (see the serial connection box), selecting the “Read” button in the “Network Parameters” box reads the network parameters for the Router-Sni er connected to Z-Con g. If the network parameters are not available (new Router-Sni er or unbound from the network) the default channel is 0x0B (CH11), the default PanID is 0xFFFF and the default extended PanID is null.

Fig. 14.d

Set the desired network parameters (channel and PanID), selecting “Write” runs the command and connects the Router-Sni er to the desired network. Only set the channel and PanID; the extended PanID must not be written, as it’s read by the network.

Fig. 14.e

If the channel and PanID are set incorrectly and do not correspond to any network in the vicinity of the Router-Sni er, the extended PanID is not detected and remains null.

Fig. 14.f

The transmission power of the Router-Sni er can be set (using the corresponding tag); to enable the value, once again select “Write”. Changing the power has no major signi cance; indeed it’s recommended to leave the maximum value (-1 dB). Selecting “Reset” resets the Router-Sni er. Selecting “Disassociate” unbinds the Router-Sni er from the current network and consequently initialises the network parameters.

Note: sif the network binding or unbinding operations are successful, an OK message is shown in the info  eld.

Important: after having set the network parameters (selecting “Write”), in order to properly initialise the program tables, close and open Z-Con g again.

Graphics Colour

This box is used to set the appearance of the connecting lines between the nodes in the “Graphics Network” window. The thickness and colour of the lines can be set based on the band the connection belongs to. The thicknesses of the lines range from 1 (thin line) to 5 (thick line). The colours of the lines can be selected from a standard colour palette.

“Data Table” window

The “Data Table” window shows a table of the devices in the network. Initially this table only shows the “Router Sni er ” device, simply called the “Sni er”. Selecting “Start Discovery” activates discovery of the nodes in the network. The process continues inde nitely until selecting “Stop Discovery”. The node currently being queried is highlighted in the table.

Fig. 14.h

Backgrounds:

All ZigBee Routers send a wireless message at regular intervals (around every 16 seconds). This message is called “Neighbour Exchange”, it’s essentially a presence noti cation message. All Routers within radio range receive the messages and use them to internally create a table called the “Neighbours Table”. This table keeps track of all the Routers that a certain Router can see in the immediate vicinity, together with the quality of the wireless signal. The table is then used to de ne the routing of the wireless messages, and consequently is fundamental in managing wireless tra c. During the “Discovery” process, Z-Con g extrac ts the data from the Neighbour Tables of all the Routers and Access Points in the network. The “Discovery” processes start by extracting the Neighbour Table of the Router-Sni er. Each Router listed in the Router-Sni er Neighbour Table creates a new row in the “Data Table”. Each Router in the table is then queried for its Neighbour Table data. This process continues until all the Routers in the network have been queried. At the end the process starts again cyclically.

Meaning of the columns:

ID: progressive number

MAC ADDRESS: MAC ADDRESS of the node, this represents the unique address of the device (8 bytes). This address is resident in the device from when it is manufactures, and cannot be overwritten or deleted for the entire life of the device. The address is represented in hexadecimal notation.

SHORT: Device network address. (This address may change during the life of the device). The address is used for routing the wireless messages from and to any other node of the network. The address is represented in hexadecimal notation.

Type: Type of device (Sni er, Access Point, Router, Sensor)

N_Neighbours: Number of Routers that the device can see in radio range.

Neighbours: Network addresses of nearby devices. These addresses are

represented in hexadecimal notation. The data are used to create the graphic links in the “Graphics Network” window.

GHOST: This column indicates whether the node is not working and consequently has been excluded. “No” indicates that the device is working correctly.

Meaning of the parameters:

Command rate [mS]:

Interval between receiving a response and sending the subsequent query (min 100mS).

Timeout Time [mS]:

Interval to wait for a response, after which a further attempt is performed.

Command Retry:

Number of consecutive transmission attempts without a response, after which the node is declared as being a Ghost; from that moment on the node marked as being a Ghost is no longer queried.

Meaning of the buttons:

Refresh Table:

Refreshes the table of nodes

Start Discovery:

Starts the network discovery process, querying the “Neighbour Table” on the Router-Sni er and then on all the Routers in the network. The network discovery process continues inde nitely, until the program is closed or “Stop Discovery” is selected.

Stop Discovery:

Ends the network discovery process.

Apply:

Notes on operation:

The information summarised in the “Data Table” is the only data that Z-Con g can extract from the network nodes. All “application layer” information, such as logical number, operating parameters or other data cannot be extracted directly by Z-Con g.

The network Discovery process involves numerous wireless messages being sent between the Router-Sni er and all the nodes in the network. This generates signi cant wireless tra c that may interfere with the normal messages being sent over the network. Consequently, the Discovery process should not be left running inde nitely but rather only for the time needed to analyse the network.

When  rst running the Discovery process or after resetting the Router-Sni er, some of the MAC addresses relating to Routers discovered in the network may be null (0000000000000000); To resolve this problem, wait until all the Routers have been discovered, stop the process, wait a few seconds, select “Clear Table” and then start the Discovery process again.

Before  rst running the network Discovery process, and when the layout of the network is modi ed (adding or moving a Router), for more precise information all the Router nodes in the network should be reset.

“Graphics Network” window

This window represents the data from the previous table in graphic form. The information helps provide a good idea of the physical structure of the network.

Tab. 14.c

Links between Routers

The connecting lines between the Router nodes indicate the quality of the respective wireless connections (LQI). The thickness and colour of the lines are set in the “System Settings” window. In the centre of the link line is a green dot that divides the line into two equal segments. The two segments of the link line represent the two mutual quality levels; the segment connected to the node represents the quality with which the node receives the messages from the other node. Often the links are asymmetrical, meaning the link line has two di erent colours (and/or thicknesses). This occurs if one of the two nodes sees the other with a stronger or weaker signal. There may be various reasons for this, for example if one of the two nodes features power ampli ers or an antenna with better gain.

Fig. 14.j

When selecting an element in the network, the bottom left corner displays the SHORT data, with reference to the device’s “Data Table” and MAC address.

Links between Routers and Sensors

For sensors the connecting line does not provide information on the quality of the wireless connection, but rather simply indicates which Router is the device’s “parent”.

Meaning of the buttons:

Print Graphics: Menu of print functions

New Region:

Button used to create a rectangle in the graphics window with customisable name and size.

Remove Region:

Button used to delete a rectangle in the graphics window.

Start Discovery:

Same function as the same-name button in the “Data Table” window.

Stop Discovery:

Same function as the same-name button in the “Data Table” window.

Identi cation of nodes in the network

Nodes can be identi ed using their MAC address printed on the device label. This is in fact the only unique value amongst the data available in the Z-Con g program. Alternatively, the device can only be identi ed indirectly (for example, switching a Router o and then seeing which of the nodes in table is marked as a GHOST after some time).

Purpose of Z-Con g

Z-Con g is essentially used to analyse the reciprocal positions of the Routers in a certain ZigBee network. It can be used to identify any critical points in the network.

Installation example:

The following  gure represents a network made up of 10 Routers, the RouterSni er and two Sensors. As can be seen, the network is divided into two subnetworks. The two subnetworks are connected by just one good quality link (the blue line that joins node 2560 to node 0730). All the other links are poor quality (they’re in fact illustrated by thin yellow lines). This situation represents a network with possible critical areas. Indeed, if there are obstacles in the link between node 2560 and node 0730, the two networks may be temporarily isolated from one another.

Fig. 14.l

Situations of this type should be corrected and, where possible, further Routers added in order to increase the number of connections between any subnetworks. An alternative to installing additional Routers is to move the existing ones to better positions.

The following  gure represents the same network in which an additional Router has been installed in a strategic position. As can be seen, the two subnetworks are connected by a further good quality link (the blue line that joins the new node 3258 to node 0680.

Fig. 14.m

Identi cation of network parameters for ModBus networks

Modbus network parameters can be read by querying the network Access Point.

The network channel is available by reading InputRegister[IR_03] on the Gateway. The network PanID is available by reading InputRegister[IR_04] on the Gateway. The network extended PanID is available by reading InputStatus[17],[18],[19],[20] on the Gateway.

Important:

Before running network Discovery using Z-Con g, all the Routers in the Modbus network should be reset, then wait around one minute. This may can done simply by sending the special reset command to all the Routers. After having completed this operation, the Gateway also needs to be reset using the special command. This operation aligns the wireless routes and provides an updated situation of the system (it updates the links between the Access Point, Routers and sensors).
