Overview

This document provides information on configuring and running the MQTTspB Simulator, including its integration with Data Explorer Tools and runtime behavior. The simulator can be started from the DataExplorer Data Explorer UI or by executing it with command line parameters, creating an MQTTspB Client that connects to a configured broker and publishes simulated data to mapped topics.

Included Features

The following features are supported:

  • Connection to brokers (local and remote) with or without username and password.
  • Customization of topic parameters: GroupID, NodeID, and DeviceID.
  • Creation of multiple NodeIDs within the same GroupID, each with its own DeviceIDs.
  • Creation of multiple DeviceIDs within the same NodeID.
  • Modification of DeviceIDs attributes using a configuration file.
  • Publishing of NBIRTH, DBIRTH, DDATA, NDEATH, and DDEATH messages.

The MQTTspB Simulator is integrated with the Data Explorer Tools, making testing easier and faster by enabling the publication of up to 30,000 simulated values to the MQTT broker from the same design environment. This facilitates project testing, communication validation with the software platform MQTT client, and testing of the new Dynamic Tag Provider functionality with MQTT.


Simulator Execution Window

You can start the simulator using the Designer at DataExplorer Data Explorer → MQTT tools, or directly thought its executable at the product installation protocols folder MQTTspBSimulator.exe

Tip

Closing that window will terminate the execution the simulator. You can minimize if you want to keep the simulation in background. 

The Execution window has the Data TreeView and EventLog at the button, and configuration panels for:

  • Simulation Control
  • Connection Parameters
  • Payload Settings

Simulation Control

This section is used to define the simulator behavior in runtimeThe Simulation Control in the MQTTspB Simulator allows users to manage the data publication process.

  • Publish One Data Sample: Sends one DDATA message for each Device created in the session.
  • Publish Continuous Data: Sends continuous DDATA messages with a time rate of 1 second.
  • Stop Publishing Data: Stop publishing continuous data.

When the simulator is connected with a Broker, those options are disabled for editing. 

You can Connect or Disconnect with the Broker with the buttons at the top of Window.


Connection Parameters

MQTTspB Simulator

Configuration

When you click on the Image Removed icon next to the command buttons, it opens the MQTTspB Simulator Configuration dialog. This configuration dialog has the following fields:

Specifies the IP address or domain name of the MQTT broker. For example, indicates a local broker running on the same machine as the simulatorIndicates the port number used to connect to the MQTT broker. The default port for MQTT is 1883, which is specified here

- Connection Parameters Configuration

Broker URL

MQTT Broker (Server) Default value is loopback (local) ip (

MQTTspB Simulator Configuration

Broker URL

127.0.0.1

).

Broker Port

Username defined on the Broker. This will be requested if the Broker needs this configuration (optional).

Username

Allows to enter the username required for authentication with the MQTT broker. This is used to verify the identity of the client connecting to the broker.

Password

Allows to enter the password required for authentication with the MQTT broker. This works in conjunction with the username to authenticate the client.

GroupId

Specifies a unique identifier for a group of clients or devices. This can be used to manage and identify clients within a specific group.

ConfigFile

Displays the path to the configuration file used by the simulator. This file contains the saved settings for the simulator, allowing for easy reconfiguration and management.

Minimized

When checked, starts the simulator minimized. This can be useful for reducing screen clutter and running the simulator in the background.

Block Configuration Field

When checked, prevents changes to the configuration fields once the simulator is running. This helps maintain consistency and prevents accidental modifications during operation.

Connect On Startup

When checked, automatically connects the simulator to the MQTT broker upon startup. This is useful for ensuring that the simulator is always connected and ready to operate as soon as it is launched.

Publish Data On Startup

When checked, enables the simulator to start publishing data immediately upon connecting to the broker. This automates the data publication process, ensuring that data starts flowing as soon as the connection is established.

Refer to the MQTTspB Simulator for detailed information.

Editing MQTT Data Structure

This configuration popup in the MQTTspB Simulator allows users to define and customize the data payload that the simulator will publish to the MQTT broker. Here is a detailed description and explanation of each section and its components:

NodeIDs

NumberOfNodes: Specifies the number of nodes (or groups of devices) included in the data structure. Default value is set to 4, meaning there are four groups of devices.

Node List: Lists the node names. By default, the nodes are named "Barcelona," "Bilbao," "Madrid," and "Sevilha." Users can add or remove nodes using the add (+) and remove (–) buttons.

DeviceIDs

Device List: Lists the devices under the selected node. By default, the devices are named "Panel_1," "Panel_2," and "Panel_3." Users can add or remove devices using the add (+) and remove (–) buttons.

Tags

Tags Table: Defines the tags associated with each device. Each row represents a variable with the following columns:

Name: The name of the variable (e.g., "Name," "State," "Latitude," "Longitude").

Type: The data type of the variable (e.g., "String," "Boolean," "Double").

VariationFlag: Indicates whether the variable should vary over time. When checked, the variable's value will change according to the specified range.

Min: The minimum value of the variable when it varies.

Max: The maximum value of the variable when it varies.

InitialValue: The initial value assigned to the variable when the simulation starts.

Controlling the Simulator

The Simulation Control in the MQTTspB Simulator allows users to manage the data publication process. Here is an explanation of each control option available:

Publish One Data Sample: Initiates publishing a single data sample to the MQTT broker. It is useful for testing and verifying if the data structure and connection are configured correctly. By publishing one sample, users can ensure the data is sent and received as expected without starting a continuous data flow.

Publish Continuous Data: Starts the continuous publication of data to the MQTT broker. When active, the simulator will repeatedly send data samples at specified intervals. This is useful for simulating real-time data streams and stress testing the MQTT infrastructure. Continuous data publishing also helps evaluate how the system handles sustained data loads.

Stop Publishing Data: Stops the data publication process, whether a single or continuous data sample. It controls the data flow and stops the simulation when necessary. Stopping data publication can be used to adjust configurations, analyze received data, or halt the simulation after a specific testing period.

Password defined on the Broker. This will be requested if the Broker needs this configuration (optional).

Start Minimized

Application starts minimized (valid for the next time the application is started).

BlockConfigurationField

Make configuration fields read-only.

Connect On Startup

MQTTspB Client tries to connect to Broker automatically when application is started (valid for the next time the application is started).

Publish Data On Startup

MQTTspB Client tries to publish Data to Broker automatically when application is started (valid for the next time the application is started).


Info

The Simulator does not support SSL Protocols.


Info

The Connection Parameter are only applied when starting the connection with the Broker.



Payload Settings

Image Added

The Payload Settings of the MQTTspB Simulator Configuration dialog allows users to manage settings related to the data payload being sent, such as GroupID, Number of NodesIDs and the Edit Data Structure button. 

  • GroupID:Specifies a unique identifier for a group of clients or devices. This identifier helps organizing and managing clients within the same group.
  • Number Of NodeIDs:Indicates the number of nodes or individual devices within the specified group. This value helps structuring the data to be sent, ensuring that the correct number of nodes is included in the payload.
  • Edit Data Structure: This button allows users to modify the data structure that will be used in the payload. Clicking this button opens a configuration popup where users can define or adjust the data points, types, and hierarchical organization of the data to be published.


Payload Data Structure

The structure is defined based on a hierarchical structure illustrated below:

    MQTTspB Simulator with the fxAssetsMonitor demo project

    Additional Information:

    Solution for when the configurations from the XML MQTTspBSimulator-Demo9.2.exe.config are applied and the tags do not appear.

    When you are using the demo project fsAssetsMonitor via the MQTTspB Simulator, it's necessary that the file "MQTTspBSimulator-Demo9.2.exe.config" be copied and pasted into the folder along with the project "fxAssetsMonitor.tproj". Upon opening the project, you can verify in Edit>Scripts>Classes, within the class CheckStatus that this class contains a method called StartMqttSimulator(). When running the project this method will fetch some arguments and together with the .config file, and from these configured arguments, the MQTTSpb Simulator will be called to run the values that are configured within this .config. When running the project this will be done automatically, without needing to manually open the simulator.

    Image Removed

    The original file "MQTTspBSimulator.exe.config" within the product's installation folder comes with default values for simulation and can be modified to generate new simulation values. To add new attributes, you can follow the pattern of the other attributes in the file.
