Nexto Logger
Nexto Series
1. Product Description
Nexto Logger is a Datalogger belonging to the Nexto Series product family. It was developed to expand the Series' fields of
activity and provides high-speed processing power in a compact design with digital and analog inputs, SDI-12 communication,
and LoRa long-distance radio integrated into the same equipment.
This product was developed with a focus on monitoring and telemetry applications, in other words, systems that collect
remote data, offering digital and analog inputs, all of them with high precision as required in the hydrological parameter mon-
itoring market, solar energy generation applications, and other areas related to science and monitoring of physical quantities.
In addition to the integrated inputs, it is possible to collect sensor data via SDI-12 network, the data is stored in the Datalog-
ger's internal memory and sent to collection stations via the integrated ethernet network or via the long range radio frequency
infrastructure, LoRa.
Nexto Logger is suitable for data collection in systems that require remote data collection. Its extended power supply
range allows applications in different areas including powering with alternative energy sources such as solar power. It can be
used in applications such as hydrology, sanitation (water and effluents), agribusiness, private and public urban infrastructure,
sensor data collection for data analysis, and other scientific applications as a replacement for traditional analytical methods. In
addition, it is an ideal solution to complement large applications together with the Nexto Series portfolio, extending the range
of applications using the same technology and engineering environment. This is a great advantage for OEMs and integrators
in these application areas where application scalability is required.

  • Page 14: Configuration And Usage

    Nexto Logger NL717 Nexto Series CE117100 Rev. B Configuration and Usage The configuration of the Nexto Logger NL717 in a LoRaWAN network is performed through an application for CPUs developed in the MasterTool IEC XE software in conjunction with the LoRa "NextoLora" library. Will be described in this topic the entire routine of creating an application and configuring the NL717 in a LoRa network, from registering the activation keys to using the library to send and receive data through the LoRaWAN network.
  • Page 15 Nexto Logger NL717 Nexto Series CE117100 Rev. B Figure 3: File -> New Project... Next, select the "MasterTool Standard Project" template, indicate the project name and path to be saved, and continue by clicking the "OK" button as illustrated in the figure below.
  • Page 16 Nexto Logger NL717 Nexto Series CE117100 Rev. B Figure 5: Selecting the device With the new project created it’s necessary to add the LoRaWAN interface library. To do this, access the "Library Manager" menu. The figure below illustrates the menu in question.
  • Page 17 Nexto Logger NL717 Nexto Series CE117100 Rev. B Figure 7: Add library In the search bar type "Nexto" and in the results you will find the "LibNextoLora" library as shown in the figure below. Double-click on it to add it to the project.
  • Page 18 Nexto Logger NL717 Nexto Series CE117100 Rev. B Figure 9: LibNextoLora library struct To configure the LibNextoLora library blocks, see the following sections. 7.1. Usage of the LibNextoLora library 7.1.1. Configuration The LibNextoLora library has a main block called LORA_MASTER, this block is responsible for executing the configu- ration and usage routines for the LoRa device.
  • Page 19 Nexto Logger NL717 Nexto Series CE117100 Rev. B The use of this structure is quite simplified and can be seen in the figure below. Besides the access keys, which should be passed via a pointer to the array where they are stored, there is a variable type for each given parameter, in these types are listed the applicable configuration options available.
  • Page 20 Nexto Logger NL717 Nexto Series CE117100 Rev. B 8. FSB8 ADAPTATIVE_DATA_RATE: The Data Rate parameter of LoRa communication indicates the bandwidth at which the message will be sent. The higher the Data Rate, the greater the capacity for sending data, i.e. more data can be sent in a single message.
  • Page 21 Nexto Logger NL717 Nexto Series CE117100 Rev. B Once the configuration structure LORA_RADIO_SET_PARAMETERS has been properly filled in the LORA_CONFIG input and the ENABLE input of the LORA_MASTER block is set to TRUE, the block will run and start the library configuration and join of the LoRa device on the server with the entered keys, the progress of the process can be observed through the LORA_STATE output of the block.
