2. INTRODUCTION
LogBox Wi-Fi is an electronic wireless data register, also known as a data logger, which comprises three analog sensors and one digital sensor,
respectively called the "analogue measuring channel" and the "digital measuring channel". With a memory capacity for up to 140,000 logs, it allows
the use of batteries, to keep its autonomy and continue to log data even during external power outages. It features a large display that offers a
comfortable view of measured variables and general device information. Furthermore, the device’s enclosure has a protection cover for the
connections, a sealing ring and a holder that allows its attachment to a wall or metal surface by means of the optional bracket with magnetic inserts.
The analog inputs accept any type of temperature sensor, such as thermocouples, Pt100 or sensors for any other quantities with current or voltage
signals. The digital channel can log the time of events, such as opening a door, or counting pulses from a flow sensor. LogBox Wi-Fi also has the
following internal sensors: temperature, battery voltage, and external power supply voltage, which can also log the values in the memory, taking the
place of any of the available measurement channels. Its wide display allows you to view up to three variables simultaneously, and displays
indications such as alarms, communication status, enabled channels, battery voltage level, among other information.
LogBox Wi-Fi also has a buzzer for audible alerts and a digital output that can be used as an alarm output or as an electronic key to power
sensors and can be controlled by several protocols, such Modbus-TCP and MQTT, for example.
The device’s configuration can be accessed through a desktop or a notebook connected to its USB interface. For use with computers, NOVUS
provides the NXperience software in your website’s download area. NXperience enables the logs’ configuration, download, and analysis, as well
as allowing them to be published in the NOVUS Cloud for remote viewing.

3. DISPLAY AND NAVIGATION
3.1 DISPLAY INFORMATION
LogBox Wi-Fi has an LCD display with 3 numerical lines of 4 ½ digits, to display the current value of all enabled channels, as well as the minimum
and maximum values thereof. At the same time, it is possible to display the current value of up to three analog channels and, in a second screen, if
enabled, the digital input current value. In addition to channel information, LogBox Wi-Fi has 7 screens with a variety of information and features
and 24 symbols that allow for easy information visualization and diagnostics.
See below an illustration of the display with a description of each symbol’s functionality.

NOVUS PRODUTOS ELETRÔNICOS LTDA. 12/53
4. OPERATION AUTONOMY
LogBox Wi-Fi is powered by an external power supply, with a 10 to 30 VDC input, or USB port. The device can optionally be powered by four
standard "AA" batteries (1.5 V each) which, in the event of a power failure in the power supply source, will keep it running for at least two years. In
this case, to reduce consumption, the Wi-Fi interface will be disabled. All other features, however, will remain in operation for at least one year.
When power from the power supply source is restored, the Wi-Fi interface will be activated, and the data logged in memory during the power
interruption will be published in the services that support backup.
While the device is operated by batteries, very high temperatures (above 30 °C) or too low (below 10 °C) will cause battery chemistry to react
outside typical operating characteristics, reducing battery life. Thus, when operating the device in these ranges, consider that the two-year
expectation can be reduced considerably.
While the device is operating on batteries, temperatures too high (above 30 °C) or too low (below 10 °C) will make the LogBox Wi-Fi circuit greatly
increase its consumption. Thus, when operating the device in these ranges, consider that the two-year expectation can be reduced considerably.
Some scenarios can also increase LogBox Wi-Fi consumption, considerably reducing battery life expectancy. Here are some examples of
situations that may decrease battery life:
•Alarm: Alarm occurrences more than once a day and with a buzzer duration over 30 seconds.
•Event Log:Events that occur with a frequency greater than once every hour.
When necessary, the batteries can be replaced with any model that has characteristics like alkaline batteries (1.5 V). However, replacement with
Energizer E91 units (identical to those accompanying the device) or Energizer L91 (which has a higher operating temperature range) is
recommended to ensure the expected battery life expectancy and specified working temperature. If you choose another battery model, it is
necessary to check its working temperature and life expectancy.
Never mix batteries of different models, or new batteries with used ones. Whenever you are replacing the batteries,
replace all of them at the same time.
Check battery polarity before inserting it into the device. Never use an inverted battery.
While the LogBox Wi-Fi is powered by batteries, and to reduce power consumption, the Wi-Fi interface will remain
disabled.

NOVUS AUTOMATION 13/53
5. INPUT SIGNALS READING
LogBox Wi-Fi allows users to choose, in addition to the channels to be registered and sensor types, some configurations that provides flexibility to
several applications, offering the possibility of weighing the energy resources (battery life) and data storage (length of log memory). Thus, it is
possible to configure the device with the following parameters:
●Log Range: Shows frequency, in seconds, with which an acquisition must be made and logged in the memory. A low periodicity will increase
battery consumption and fill up the memory faster.
○Minimum Range:
■1 second (if no channel is configured to operate on average);
■10 seconds (if a channel is configured to operate on average).
○Maximum Range: 18 hours.
●Display Update Range: Shows frequency, in seconds, with which an acquisition must be made and updated on the display. It allows you to
save memory by configuring it to a larger range of logs without damaging the Display update rate. Low frequency increases battery
consumption. This range can be disabled if set to ‘0’. Thus, the display update will take place in the log range.
○Minimum Range: 1 second;
○Maximum Range: 1 hour.
When configuring a Display Update Range, it should be less than the Log Range. Otherwise, it will be ignored, and the display will be updated at
the same Log Range.
The Display Update Range only updates Analog Channels that are not configured to operate on average. Thus, the Digital Channel that is
configured to operate in counting mode and the Analog Channels that are configured to operate on average will only have their information updated
at each log range.
If the digital channel is operating in the "Event Log" mode, each event will update its respective information on the display.
5.1 ANALOG INPUTS
LogBox Wi-Fi has three channels for reading analog signals. The types of signals and sensors accepted by them are:
●Temperature Sensors:
○Thermoresistance Pt100;
○Thermocouples J, K, T, N, E, R, S, and B;
○Internal Temperature Sensor.
●Linear Sensors:
○0 to 50 mV;
○0 to 5 V;
○0 to 10 V;
○0 to 20 mA;
○4 to 20 mA.
●Internal Diagnostic Sensors:
○Battery Voltage;
○External Power Supply Voltage.
Each type has specific operation configurations and characteristics. Its configurations and characteristics are described below:
●Temperature Sensors:
○Inform the measured temperature within the possible measuring range of each sensor;
○The maximum resolution for the Temperature Sensors is 0.1 °C;
○You can configure them to be displayed with one or no decimal places;
○You can configure them to be displayed in units of measure °C or °F.
●Linear Sensors:
○Inform you of some magnitude in the range required by the user (defined in the parameter "User Range"), as configured in the "Lower
Limit", "Upper Limit", and "Number of Decimal Places" parameters.
■Number of Decimal Places: Allows you to choose to use 0, 1, or 2 decimal places.
■Lower Limit: Corresponds to the value configured to represent the minimum value of the chosen sensor:
●Minimum -19999 to 0 decimal places;
●Minimum -1999.9 to 1 decimal place;
●Minimum -199.99 to 2 decimal places.
■Upper Limit: Corresponds to the value configured to represent the maximum value of the chosen sensor:
●Maximum 19999 to 0 decimal places;
●Maximum 1999.9 to 1 decimal place;
●Maximum 199.99 to 2 decimal places.

NOVUS AUTOMATION 14/53
○You can configure them to be displayed in units of measurement °C, °F or in a custom unit of up to 8 characters, which will not show on
the display;
○The maximum resolution for linear sensors corresponds to a ratio between the user range and the maximum resolution of the chosen
sensor.
●Internal Diagnostic Sensors:
○Inform the voltage of the possible LogBox Wi-Fi power supply sources;
○The maximum resolution for the internal diagnostic sensors is 0.01 V;
○You can configure them to be displayed with 0, 1, or 2 decimal places;
○The unit of measure for these sensors is Volts and no unit symbol is displayed.
Refer to the Technical Specifications chapter to check these signals’ accuracy. Refer to the Installation chapter to check these signals’ connection.
An analog/digital (A/D) converter with high resolution and accuracy is used to read the sensors connected to the analog channel inputs. In the
desired scan range, all the analog channels enabled will be read.
Each type of input signal has a valid measuring range (refer to chapter Technical Specifications) for more information. However, the device can
typically measure signals which slightly exceed the limits of this range. The amount it can measure beyond it, however, depends on the type of
input configured and can vary between different devices.
The following table describes the input types supported by the device, the device’s signal conditions and their respective indications.

Table 02– Measurement and indication of input types by LogBox Wi-Fi
LogBox Wi-Fi allows you to configure settings to be applied to analog sensor readings. These settings can be used to correct errors in the sensor
or process in which the sensor is installed and applied individually for each analog channel. Two adjustment modes are provided by the device:
•Offset: Allows each analog channel to choose an Offset value to be added to the channel reading indication. It is a simple and fast feature to
adjust the display throughout the range.
•Custom Calibration: Allows you to enter up to 10 set points for each channel to correct distortions in reading these channels at these points.
We call this characteristic a "custom calibration" because it allows the user to adjust the indication at the desired points by zeroing their errors.
The adjustment is made linearly between the points entered, according to the values entered.
It is important to note that both the Offset adjustment and the insertion of custom calibration points are optional, only indicated for those who wish to
adjust the indication to a local standard, since the LogBox Wi-Fi has already been calibrated at the factory.
Whenever you change the input type, make sure that the custom calibration points of the previous input are deleted!
For each analog channel, a unique (Tag) name must be assigned, which will be used to reference the channel. You should also choose the type of
input (sensor) that will be connected to that channel. In addition to that, you can assign the unit of measured value: for temperature sensors (Pt100
or thermocouples), degrees Celsius (°C) or Fahrenheit (°F); for linear sensors (current or voltage), you can enter the desired unit.
In the case of linear input types, one must choose the sensor indication range, that is, what the channel should indicate when the input is at its
minimum value and what it should indicate when it is at its maximum value (minimum and maximum values considering the LogBox Wi-Fi working
range for the chosen input type). Once the 4 to 20 mA input type is chosen, for example, a pressure transmitter from 0 to 2 bars will be connected.
In this case, "0.0" must be chosen as the minimum value and "2.0" as the maximum value in the input configuration. All resolution and accuracy
available will be contained within the chosen range.
When a simulator is used on analog inputs that are connected to the mains (e.g. a thermocouple or voltage simulator) and it is not isolated, it is
recommended to use a different reading interface than USB. In some cases, the occurrence of noise and read Offsetshas already been detected
due to the influence of the USB cable connection, probably by ground loops.
LogBox Wi-Fi, when operated by batteries, keeps the entire analog circuit switched off while no acquisition is being made. This strategy is
necessary so that it can operate for more than two years without needing to change batteries. This characteristic may cause some undesirable
effects during calibration, as some analog signal simulators (e.g., thermocouples simulator or a Pt100) may not operate properly, causing false
reading Offsetsand oscillations. Should such a problem be identified, it is recommended to power the LogBox Wi-Fi By external source or USB
cable while using a simulator.
Setting the local network frequency (50 Hz or 60 Hz) is important as it helps improve the performance of reading analog channels even while the
device is running on battery power. Usually, the power grid causes interference in the signal read from the sensors, which can be more easily
mitigated if we know the frequency.

5.2 DIGITAL INPUT
LogBox Wi-Fi has a Digital Input channel that can be configured for "Pulse Count", "Event Log", or even for "Logs Control" modes. This Digital
Input can be disabled.
Regardless of the function for which it will be used, you must configure the type of sensor output that will be connected to the input: PNP, NPN, or
Dry Contact (refer to chapter Installation to see how the sensors should be connected). In addition to that, it is necessary to select the edge of
interest of the digital signal to generate the count, event, or start/end of logs: rising edge, falling edge, or both edges.

Table 03- Digital Input
For Dry Contact sensors, it is necessary to set a debounce time of at least 50 ms (sensor stabilization time / time in which the sensor must remain
in the state of interest for it to be considered valid). For PNP or NPN type sensors, if configured in "Pulse Count" mode, it is not necessary to set a
debounce time. However, if the digital input is configured for the "Event Log" or "Logs Control" modes, a minimum debounce of 50 ms is required to
prevent any noise from generating a false event. In the "Event Log" and "Logs Control" modes, events will be generated after the end of the
debounce time.
5.2.1 PULSE COUNT
By setting the Digital Input on the "Pulse Count" mode, it will be possible to count the number of pulses occurring within a period and to log the
average flow rate. LogBox Wi-Fi has a 16-bit register for accumulating the number of pulses within a given range and logging it in the memory.
Thus, at each log range, LogBox Wi-Fi captures the number of pulses and logs it in the memory, zeroing the register to accumulate the pulses for
the next interval.
If the sensor is a Dry Contact sensor type, the LogBox Wi-Fi will be able to count to 10 pulses per second. For PNP and NPN sensors, 2000
pulses per second. However, it is important to note that these pulses will accumulate within the log range. Thus, it is necessary to evaluate the
sensor maximum frequency so that it does not exceed 65535 counts (16 bits) within the log range and overflow the register that accumulates them.
If the maximum sensor frequency is 2 kHz, the LogBox Wi-Fi will accumulate 2000 pulses per second for up to 32 seconds. By exceeding this
range, the number of accumulated pulses will exceed 65535 counts, resulting in overflow in the accumulator register. For a sensor that can reach
2000 pulses per second, it is recommended that the log frequency be less than 32 seconds.
In typical applications, such as flow and volume measurement, simple pulse counting is not enough, being necessary to convert these pulses into a
flow unit. For this, one can select the desired flow unit and a conversion factor which will transform the number of pulses generated by the
connected transmitter in flow information. The pulse conversion logged in the range for the flow unit configured by the user will occur every time the
logged data is displayed.
To streamline the digital channel configuration in "Pulse Count" mode and the conversion to flow in the unit required, LogBox Wi-Fi provides the
following units of measure:
Flow Units

l/s,
l/min,
l/h,

m³/s,
m³/min,

pulses/l,
pulses/gal,
pulses/m³.
Table 04 – Units of Measure

NOVUS AUTOMATION 17/53
If the user uses any of the flow and sensor units, it is necessary to inform the sensor factor. If none of the available units are required, you will need
to calculate the user factor by relating the parameters "User Unit", "Sensor Unit"and "Sensor Factor", and fill it in so that the device correctly
converts the pulses to the required unit. In this case, LogBox Wi-Fi will convert the pulses to the user unit as follows:
●User Value = (Count)/(Sensor Factor)*(User Factor)
○It is necessary to consider that the log range is 1 second and will not influence the calculation. Internally, LogBox Wi-Fi always considers
the log range.
Fig. 02 – Digital Input Screen
Let’s say, for example, that an application has a PNP-type sensor that computes a produced part every 30 rising-edge pulses and that the user
wants to visualize the production in parts per minute. The following parameters must have been configured on the device’s digital input:
•Log Range: It must be configured to log the maximum sensor frequency.
•Input Mode:Pulse Count.
•Sensor Type: PNP.
•Counting Edge: Rise.
•Unit and Sensor Unit: Custom.
•Sensor Factor: 30 (pulses/part).
•User Factor: 60 (conversion of parts per second to parts per minute).
Thus, LogBox Wi-Fi will record the number of pulses occurring within that period at each log range, and every time the data is displayed, it will
transform those pulses into the number of parts produced per minute (user-customized unit).
In the same example, it is possible to assume that the log range is 20 seconds. Thus, if the sensor gives 20 pulses per second, the LogBox Wi-Fi
will register 400 pulses per range, displaying 40 parts per minute (((20 pulses/s)/(30 pulses/part)) * 60 (1 min) = 40) for the user.
5.2.2 EVENT LOG
If the digital input is configured in the "Event Log" mode, each selected edge will create a log in memory, informing the event and the instant that it
occurred. This log will not be synchronized with the periodic logs, but will respect the logs beginning and end modes. Events will be logged after the
end of the debounce time set and will be logged with the debouncetime delay. LogBox Wi-Fi can log up to 10 events within 1 second.
5.2.3 LOGS CONTROL
It is possible to use the digital input to start and/or pause the logs of the other input channels. Once configured in the "Logs Control" mode, each
selected edge will start or stop the process of in-memory logs. As in the "Event Log" mode, detected events will only act after the configured
debounce time expires. Thus, the start/pause of the logs will be performed with the debounce time delay.

NOVUS AUTOMATION 18/53
6. DIGITAL OUTPUT
The LogBox Wi-Fi has a PNP-type Digital Output which when triggered places the voltage from the external power supply to the respective
terminal and can be disabled or configured to operate in one of the modes described below:
●Auxiliary Electronic Switch: Allows you to control the power supply of external instruments during analog channel readings.
4-20 mA transmitters, for example, can be fed by the digital output pin, so that they are only turned on when they are read – which would save
energy from the LogBox Wi-Fi external power supply, which can be a 12 V battery. In the "Auxiliary Electronic Switch" mode, it will be
necessary to configure how long before each acquisition the digital output must be triggered.
○Drive Time: It defines, in seconds, how long before each acquisition the digital output must be triggered. It will be deactivated when the
acquisition is ready. Such time cannot be longer than the lowest acquisition range (Instant, Average = 1/10 of the snapshot, Interval of
Display Range). If equal to 0, the Auxiliary Electronic Switch will be enabled at the exact moment of an acquisition. If greater than or equal
to the lowest acquisition range, the Auxiliary Electronic Switch will remain be enabled.
●Alarm Status: Allows you to follow the current general alarm status. If any channel is in an alarm situation, the Digital Output will be triggered.
If no channel is set to alarm, the Digital Output will be disabled.

7. MQTT PROTOCOL
LogBox Wi-Fi is compatible with the Message Queue Telemetry Transport (MQTT) protocol, a protocol designer for low data bandwidth
consumption and which uses the Publish/Subscribe paradigm for message exchange.
Acting as a Publisher/Subscriber MQTT, LogBox Wi-Fi requires a middleware named Broker, responsible for sending messages from Publishers
to Subscribers, to operate. LogBox Wi-Fi is, simultaneously, a Publisher, with 7 publication topics, to provide information about sensors and
several device statuses and a Subscriber, with 1 inscription topic, to receive possible parameters alterations and to remotely offer a certain control
level to the user.
7.1 PUBLICATION TOPICS
When connected to a Broker, the LogBox Wi-Fi can register up to seven topics, which will be presented below. Check the Frame Parameters
section of this chapter for more information about the frames that molded the responses to each publication topic.
The message sent in each topic corresponds to a JSON frame, which encapsulates several parameters. In the frame, these parameters correspond
to strings. Values of each parameter, however, must be processed differently.
7.1.1 STATUS TOPICS
•novus/<sn>*/status/channels: Topic for the publication of the last log of the analog channels and digital channel in "Pulse Count" mode.

7.1.2 LOGS TOPICS
•novus/<sn>*/log/channels: Topic for the publication of all logs of the analog channels and digital channel in "Pulse Count" mode. Used
mainly when there is loss of communication link with the Broker or lack of external power, as it will receive all historical logs.

"alarm_high":[0,0,0,1], "buzzer_state":0}
•novus/<sn>*/log/event: Topic for the publication of all logs of the analog channels and digital channel in "Event Log" mode. Used mainly
when there is loss of communication link with the Broker or lack of external power, as it will receive all historical logs.
Example: {"timestamp":43277.82236111,"event_type":"down","millisecond":630}
7.1.3 CONFIGURATION TOPIC
•novus/<sn>*/config: Topic for the publication of the device configuration. It shall be published at the latest every five minutes.

7.1.4 RESPONSE TOPIC
•novus/<sn>*/response: Topic for the publication of the commands response received by the device. Table 06 lists the permissible error
responses for this topic.
Example: {"config_receive":"ok","error_type":"none","parameter":"none"}
7.1.5 IDENTIFICATION TOPIC
•novus/neighbor: Topic for the publication of the identify from the device(s) connected to the Broker. It shall be published at the latest every
five minutes.
Example: {"model":"LogBox Wi-Fi", "serial":12345678, "ip":"192.168.88.10", "mac":"B0:38:29:5D:FE:B1" ,"lqi":-40,"firmware_version":1.00}
