Overview of devices

An overview of this product design and usage. Also contain circuit diagrams, terminal details, etc.,

Key Features

Sensor Compatibility: The TI3-40B supports the connection of up to four external temperature sensors. These sensors can include thermocouples (TC/TZ) with 2-wire connections, as well as resistance temperature detectors (RTDs) such as Ni1000, Pt1000, and Pt100 with both 2-wire and 3-wire connections.

Applications: This unit is suitable for various temperature monitoring applications where readings are required from different locations. Examples include large floor heating systems with sensors arranged diagonally, monitoring indoor and outdoor temperatures, or measuring temperatures in different zones of a building or in different components of a heating system (e.g., boiler, solar heating).

Status Indication: The unit features a green RUN LED on the front panel to indicate its status:

- Continuous illumination of the RUN LED indicates that the unit is receiving power from the supply voltage (powered via the BUS), but it is not communicating with the master unit.

- Flashing of the RUN LED indicates that the unit is powered and actively communicating via the standard BUS.

Mounting: The TI3-40B unit is designed specifically for mounting into an installation box, providing ease of installation and integration into existing systems or infrastructure.

Programming in iDM

Introduction

iNELS Design Manager, or IDM3, is for programming iNELS units. This software serves as the platform for configuring device parameters, defining functions, and executing the programming required for iNELS units.

Device parameters, such as sensor range and thresholds, backlights, and operational modes, can be easily adjusted within the IDM3.

The process of programming in IDM3 typically involves defining functions and establishing logical connections between different devices. This allows for the creation of automation scenarios and the implementation of intelligent control strategies.

Starting up

Select the "blue control icon" as shown in Fig 1 > Clicking on the option "New project from default template“ allows you to create a new project from a predefined template.

Select the "Device manager" (Fig 1)> Add "New unit "> Select the central unit > Add "New unit">Select the "Internal-Master/ BUS"> Add "New unit "> Add the devices> Click on the devices to see the "Parameters".

Parameters:

Parameters in the iNELS devices refer to the measurable factors or characteristics that define the behavior or performance of the device. These could include electrical properties, physical dimensions, environmental conditions, and various other specifications depending on the type of device.

These are settings specific to individual devices within your automation system.

The specific parameters of the TI3-40B in the iDM as shown in Fig.2

Clicking on the TI3-40B (Fig.2), we can see the selected firmware, address, name, and description, along with other parameters as described below :

It is important to add the device address for proper communication with the unit. The Hexadecimal device address can be find from the device.

TIN1-4: The TI3-40B is a temperature interface module designed for connecting external temperature sensors to a control system. Each of the four parameters (TIN 1-4) refers to a specific temperature sensor input on the module.

Sensor Type: This parameter specifies the type of temperature sensor connected to the corresponding input. It has the option to select sensor types such as: TC, TZ, T_Ni1000, T_Pt100, T_Pt1000, Calibration.

Offset Temperature: The offset temperature allows you to calibrate the sensor readings by adding or subtracting a constant value. This is useful for compensating for inaccuracies in sensor measurements or for aligning readings with a reference temperature.
Minimal Temperature: This parameter sets the minimum allowable temperature reading from the sensor. If the temperature measured by the sensor falls below this value, it may indicate a fault condition or trigger an alarm.
Maximal Temperature: Similarly, the maximal temperature parameter sets the maximum allowable temperature reading from the sensor. If the temperature measured exceeds this value, it may indicate a fault condition or trigger an alarm.
Average Time : - Defines the time period over which multiple temperature readings are averaged to obtain a stable and accurate measurement.

Exports for iNELS Cloud and APP

Setting Up Control and Monitoring for iNELS Cloud and iNELS App

It is possible to control and monitor all the bus units in iNELS cloud and iNELS app. There are two stages to set up this function. Stage one is to do configuration in iDM3 and stage 2 is to do Configuration in iNELS cloud page and iNELS app.

Configuration in iDM3.

1. Unit and Parameter Selection:

Begin by accessing the iDM3 interface on your PC connected to CU. Navigate to the Device Manager section and carefully select the units and parameters you wish to control. This step is essential for determining what gets exported to the iNELS cloud and app.

2. CU Configuration and Third-Party Settings :

After the above step, go to the CU configuration in the iDM3, and select the page for third-party settings.

Inside the third-party settings page, designate the port for cloud connection. Set the mode of operation and choose the numerical system as hexadecimal. Pay close attention to verifying and configuring all essential parameters for successful cloud export.

3. Cloud Settings:

Move on to the Cloud Settings section within iDM3.

Input the details of your iNELS cloud account. If you haven't created one, utilize the "New User" tab on the iNELS Cloud web page to establish a free account. (Inels Cloud - ElkoEP).

Select the mode and input the cloud account credentials. Save the project to the central unit to generate and store the export project file in the iNELS cloud account.

Configuration in iNELS cloud page and iNELS App.

1. Online Status Verification:

Once the cloud credentials and export settings in iDM3 are configured successfully, check the iNELS cloud account's Gateway section. Confirm that the Central Unit (CU) is online and that the export file has been automatically sent to the cloud under your account.

2. Device Creation in Cloud Platform:

In the cloud platform, you have to create new devices in order to control it remotely.

In the device tab, you will find the add device button, which can be used to associate export elements from IDM with the required types and icons.

After entering any name of the device, you select the icon, the MAC address of the communication gateway (in this case CU3), a specific type of device and the address of a specific function and element from the iNELS BUS system.

In order to be able to use the iNELS application to control the devices from CU over the local network or the cloud, it is necessary to create a room for bus devices for each central unit and add the devices into the room.

Follow these steps meticulously to ensure a seamless configuration process for controlling and monitoring all bus units through iNELS cloud and iNELS app.

3rd Party Integration with iNELS BUS

3rd Party Integration (MQTT)

iNELS units support MQTT integration on central units CU3-07M, CU3-08M, CU3-09M, and CU3-10M. It is necessary to select the devices and parameters for 3rd party integration on the device manager in the iDM.
Please note that you have an MQTT broker (local or cloud) running in the installation for this integration.
After you have a working MQTT broker you need to configure iNELS Central units to communicate with it. If you have no knowledge of what MQTT is, you can learn about it from MQTT Essentials articles. https://www.hivemq.com/mqtt/
There is a pre-installed MQTT broker in the iNLES bridge, it can be used to connect the iNELS Central units for integration in your projects.

Configuration in iDM3: Select units of 3rd Party integration.

Unit and Parameter Selection:

2. CU Configuration and Third-Party Settings :

After the above step, go to the CU configuration in the iDM3, and select the page for third party settings.

Inside the third-party settings page, designate the port for third-party connection. Set the mode of operation and choose the numerical system as hexadecimal. Pay close attention to verifying and configuring all essential parameters for successful third-party integration.

3. MQTT Settings:

Move on to the MQTT Settings section within iDM3.

Input the details of your MQTT broker.

Select the mode and input the broker credentials such as IP, port username and password. Save the project to the central unit.
