The default value is Disabled (which provides a linear reading as described above), having also the option to provide a fixed reading equal to lower and upper limits (“0” or “30000”).

Compatibility with Other Products

To develop an application for Nexto Series CPUs, it is necessary to check the version of MasterTool IEC XE. The following table shows the minimum version required (where the controllers were introduced) and the respective firmware version at that time:

Table 14: Compatibility with other products
Additionally, along the development roadmap of MasterTool IEC XE some features may be included (like special Function Blocks, etc…), which can introduce a requirement of minimum firmware version. During the download of the application, MasterTool IEC XE checks the firmware version installed on the controller and, if it does not meets the minimum requirement, will show a message requesting to update. The latest firmware version can be downloaded from Altus website, and it is fully compatible with previous applications.

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.
Registering a device in a LoRaWAN network requires prior configuration of the device on the server where it will be registered. This configuration will contain the radio frequency parameters that must be applied as well as the server access keys. During the creation of a new device (called end node) in the server, several configurations should be noted for later use when configuring Nexto Logger in the LoRaWAN network.
Among these configurations are:

• Frequency Plan (or Regional Band): This parameter defines the frequency plan that the device will operate on. The setting of this parameter must be in absolute parity between all elements that involve the LoRaWAN network, such as the server, Gateway and End Device. (e.g. AU915).
• Frequency sub-bands (or FSBs): Some frequency plans also offer the configuration of communication sub-bands. As with frequency plans, sub-bands must be configured accordingly on all network elements (e.g. FSB1).
• Adaptive Data Rate (ADR): Defines the optimization of the choice of radio parameters in the device. When enabled, it allows the server to choose the parameters optimally (e.g. TRUE).
• Unique Device Identifier (or Device EUI): Unique identifier of an End node, can be generated by the server or provided by the device itself. This identifier is a 64-bit key, usually expressed in 8 hex bytes (e.g. [01 02 03 04 05 06 07 08]).
• Class: Defines the mode in which the end node will communicate over the LoRaWAN network. This parameter should be chosen according to the needs of energy use. Class A devices use less energy with some penalties in communication availability. Class C devices are always available on the network, but use more energy
• Activation Modes: Defines the mode in which the end device will be registered to the server. There are two ways of doing the device validation procedure on the server. The first, called Over the air activation (OTAA), activates the device via radio communication. During this process, the device communicates with the server using two identification keys for the server and the application, and then the security and encryption keys are exchanged between the server and the device in a secure manner. This activation process is called JOIN and ensures that the encryption keys are hidden, maintaining the security of the network and the secrecy of the communication content.
  The two keys required for the JOIN by OTAA process are:

1. Unique application identifier (APP EUI): 8 byte key. (e.g. [01 02 03 04 05 06 07 08]).
2. Application Key (APP Key): 16 byte key (e.g. [01 02 03 04 05 06 07 08 09 0A 0B 0C 0D 0E 0F 10]).

The second activation mode is called Activation By Personalization (ABP), in this activation mode the security keys are generated by the server and loaded manually on the end device. Since these keys are responsible for encrypting the content of the communication, this activation mode is highly insecure and should not be used in applications that demand high reliability. This activation mode does not perform the JOIN process, since the keys will be written directly to the device. Altogether there are two security keys and one device address.

1. Application session key (APP Session KEY): 16 byte key.
2. Network session key (NWK Session KEY): 16 byte key.
3. Device Address (Dev ADDR): 4 byte key (e.g. [01 02 03 04]).

Once you have the access keys and the other activation configuration parameters for the device, you can start the device on the network without difficulty. The first step is to open the MasterTool IEC XE development software and create a new project.
The procedure for creating a new project can be seen in the following figures.
When opening MasterTool IEC XE access the menu “File” and then “New Project…” as illustrated in the figure below.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.Then choose the target device for the application. In this case, you should configure the Datalogger NL717 device, found in the “Datalogger Controllers” category. As illustrated in the figure below.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.A new library management tab will open in the main window of MasterTool IEC XE, click on the “Add Library” menu to access the menu for adding a new library to the project. The figure below illustrates the location of the access button.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.Once included in the project it is possible to check the functional block of use, as well as the associated data structures.
The block called LORA_MASTER is the only user interface of the library and provides all the operating states of the device through its state structures.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 configuration and usage routines for the LoRa device. Device related settings are performed via the LORA_CONFIG input of the LORA_MASTER block, which receives a data structure of type LORA_RADIO_SET_PARAMETERS. Before executing the LORA_MASTER block via the ENABLE input, it is necessary to configure and assign its input parameters. 7.1.1.1.LORA_RADIO_SET_PARAMETERS
With the development environment configured and having the keys and configuration parameters, it is possible to start the development of the application that will configure the device in the LoRaWAN network.
The device-related settings are made via the LORA_CONFIG input of the LORA_MASTER block, which receives a data structure of type LORA_RADIO_SET_PARAMETERS to be used as input parameters.
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.The types of configuration variables and their respective available options are:

• REQUEST: Enables a new configuration on the device, if the device does not yet have a valid join.
• FORCE_CONFIG: Forces a new configuration on the device, even if the device already has a valid join.
• REGIONAL_BAND: Defines the frequency band that will be used for LoRa communication. Frequency bands are groupings of frequency channels in which the device will communicate via the LoRa protocol. Each country has its own regulations and pre-definitions for the use of the radio spectrum for communication, so the device must operate in different frequency bands that fit the laws of the region where it will be used. Configuration options:

1. According to the region where it is used. In Brazil: AU915.

• DEV_EUI: Unique device identification key. Receives the pointer to the vector containing the saved key.
• MAX_PAYLOAD_LEN: Defines the maximum size of the message that can be sent. Represents the maximum size in bytes that the device can send. Takes the integer value from 1 up to a maximum of 36.
• ACT_CLASS: The activation mode refers to the way the device sends and receives messages. When activated in ClassA the device prioritizes saving power and in ClassC prioritizes the availability of sending and receiving messages. It is recommended to use ClassC in all cases except when there is a need to save power. Configuration options:

1. ClassA
2. ClassC

• FSB: Frequency sub-band, within the regional bands there are also working frequency sub-divisions, the so-called frequency sub-bands (FSB). This should be chosen in parity with the working subband chosen in the Gateways and the server, by default the NL717 and GW700 devices use FSB2 for working. Configuration options:

1. FSB1
2. FSB2
3. FSB3
4. FSB4
5. FSB5
6. FSB6
7. FSB7
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. Conversely, the higher the Data Rate, the less effective the communication over long distances, significantly decreasing the communication distance. When the ADAPTATIVE_DATA_RATE mode is activated, the server takes care of choosing the ideal Data Rate for device communication, this adaptation process is time consuming and can cause a lot of communication instability, with few real gains associated with it. It is recommended to disable this function, so the device will communicate at the lowest Data Rate, but having a significant gain in communication distance.

• ACT_TYPE: Mode in which the device will be joined on the server. The first join mode, OTAA, allows the device to exchange access and encryption keys with the server during the join process. In this way the encryption keys are hidden and secure during the entire process, this is the most secure mode of join. In the second join mode, ABP, the access and encryption keys are pre-generated and loaded on the device before the join process. This mode offers a faster and easier join process but is less secure, since the encryption keys can be misappropriated. Configuration options:
  1. OTAA
  2. ABP

• ABP_KEYS: Receives a structure of type LORA_ABP_CONFIGURATION that must be filled in if the choice of join mode is of type ABP.

• LORA_ABP_CONFIGURATION: Different from the others, which list available options, this is a data structure that contains the three keys needed for the join of ABP type.
  1. ABP_APP_SESSION_KEY: Receives the pointer of a vector that contains the saved key;
  2. ABP_NWK_SESSION_KEY: Receives the pointer of a vector that contains the saved key;
  3. ABP_DEV_ADDR: Receives the pointer of a vector that contains the saved key.

• OTAA_KEYS: Receives a structure of type LORA_OTAA_CONFIGURATION that must be filled in if the choice of join mode is of type OTAA.
  • LORA_OTAA_CONFIGURATION: Data structure that contains the two keys needed for the join of OTAA type.
  1.OTAA_APP_EUI: Receives the pointer of a vector that contains the saved key;
  2.OTAA_APP_KEY: Receives the pointer of a vector that contains the saved key.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.

7.1.2. Current status of the library
The LORA_STATE output informs the user of the current library and device state via the enumerable LORA_LIB_STATE that identifies what is happening in seven states. These are:

1. DISABLED: It informs that the block is disabled;
2. INITIALIZING: It informs that the block is initializing;
3. INITIALIZATION_FAIL: It informs that some failure occurred during block initialization;
4. INTERNAL_ERROR: It informs that there are internal errors preventing the block from working;
5. NOT_JOINED: It informs that the block has joined correctly but the device is not yet activated;
6. JOINED_RDY_TO_SEND: It informs that the device is joined and ready to send messages;
7. JOINED_SENDING_DATA It informs that the device is joined and performing the LoRa messaging process.

Once initialized, the block will perform a device join verification process, if the device already contains valid join in-formation, this information will be used unless a new forced join is requested by the user via the FORCE_CONFIG variable of the  LORA_RADIO_SET_PARAMETERS data structure. The join process is sometimes time consuming and can take anywhere from seconds to hours in extreme cases to complete successfully (it depends on the signal quality between the device and the LoRa Gateway). During the join process the library will remain in the NOT_JOINED state and will change to JOINED_RDY_TO_SEND once successfully joined.
Once joined, the device is ready to send LoRa messages. The process is done via the LORA_SEND input of the block that must be supplied with a structure of type LORA_SEND_PARAMETERS in this structure are all the necessary information for sending a message.
7.1.3. Message sending configuration
7.1.3. 1.LORA_RADIO_SEND_PARAMETERS The description of each of the variables in this data structure is as follows:

• REQUEST: Requests a new message sending;
• LORA_CONFIRMATION: Sets the message confirmation mode;
• LORA_PYLD_LEN: Informs the size of the message that will be sent;
• LORA_PYLD_BUFF: Address of the buffer that contains the message that will be sent.

The state of the block will remain in JOINED_SENDING_DATA while the sending process is being performed, this process takes about 30 seconds. Once the sending is complete, the library state returns to JOINED_RDY_TO_SEND informing that the block is ready for a new sending.
7.1.4. Received messages
Messages received by the LoRa device can be viewed via the PAYLOAD_RECEIVED output of the block, a data structure of type PYLD_RECEIVED is used to report the received message data, these are:

• PYLD_COUNTER: Informs the total number of messages received;
• PYLD_LEN: Informs the size of the received message;
• PYLD_BUFF: Buffer that contains the received message.

7.1.5. Block Diagnostics
Via the STATUS output from the LORA_MASTER main block, it is possible to check all the information regarding the LoRa device, as well as the codes of the possible errors that might happen.
This output returns a data structure of type LORA_TOTAL_STATUS. This structure has three outputs (ERROR_CODE, LORA_GET_PARAM and ERROR_STATUS).
A binary variable is associated with the ERROR_STATUS output, which returns TRUE when an error occurs. The structures associated with the other outputs are:

1. TOTAL_ERROR_LIST: Associated with the ERROR_CODE output, it contains a complete list of possible error causes, plus the error code of the last occurrence;
2. LORA_GET_PARAM: Associated with the LORA_GET_PARAM output, it contains the activation information that was read from the LoRa device.
