    Expanding I/O Capabilities of NORVI Series

    I/O (input/output) is a critical part of any programmable logic controller (PLC) system. It allows for the efficient and reliable connection of external devices to the PLC, allowing for more complex control systems.

    NORVI ESP32 Industrial Arduino, has served with the best I/O combinations for both monitoring and controlling applications. On the base unit, NORVI Controllers offer below I/O Capabilities. 

    • Digital Inputs
    • 4-20mA Analog Inputs
    • 0 – 10V Analog Inputs
    • Transistor Outputs 
    • Relay Outputs

    We are planning to discuss the capabilities of the Digital Inputs , Transistor outputs in a separate document. Including how they can be utilized for industrial applications. 

    While we discover more and more use of the NORVI Industrial Controllers we added the expandability of I/O Capabilities.

    The most obvious advantage of using I/O expansion in an Arduino PLC system is the ability to connect more external devices and increase the capacity of the system. With the use of I/O expansion, the number of devices that can be connected to the Arduino PLC can be increased significantly. This provides the user with greater flexibility, allowing them to control more devices with a single PLC. 

    Another advantage of I/O expansion is the improvement of system reliability. By connecting more external devices to the PLC, the system can be monitored and controlled more accurately. This ensures that any errors or malfunctions in the system are detected quickly and efficiently. In addition, I/O expansion can help to reduce the cost of a PLC system. By adding more I/O expansion, the total cost of the system can be reduced. This is because the cost of the additional I/O expansion is much lower than the cost

    We have launched below expansion products; 

    1. Analog Input Expansions
    2. Digital Input Expansions
    3. Transistor Output Expansions
    4. Relay Output Expansions

    In the near future, we will be launching the LoRaWAN expansion module to enable users to get the best out of NORVI Controllers.

    Programmable MQTT Devices – NORVI

    Programmable MQTT Devices - NORVI

    The Industrial Internet of Things is a network of sensors and other devices that communicate with industrial systems, all in an effort to enhance the business operations. Manufacturing, agribusiness and oil & gas to name a few, all use a large range of sensors.These sensors transmit essential telemetry data to analytics engines, which search the data for patterns and irregularities, allowing businesses to better understand and optimize their operations.

    To transfer data from a field sensor to a field controller, to a site network, to a PC data server, and then to the cloud, conventional automation products and protocols usually require a rigorous configuration and hierarchy. These types of implementations can be difficult to develop and maintain. MQTT, which includes multiple functions to satisfy the needs of IIoT, has risen to popularity as a protocol for solving this issue. MQTT is a light and energy-efficient communication protocol with a fast response time.It makes the interaction between devices efficient, regardless of the number of devices involved.It guarantees fast data delivery with low latency all while reducing CPU and RAM load.

    Imagine a cloud-controlled device to measure the humidity in a farm, remotely. In the case of HTTP protocol, the device would have to continuously make GET requests to see if there’s a change in a variable, say “Humidity Variable“, and then take an action depending on the last reading. This necessitates a huge number of requests, and it isn’t entirely real-time because it is dependent on the polling frequency.MQTT allows the user to listen to the cloud and receive notifications only when a variable changes. The communication between the computer and the cloud is kept open in this manner, but data only moves when it is needed, saving battery life and network bandwidth while enhancing real-time performance.

    So it is clear that MQTT-capable industrial automation devices are the latest approach for combining commercial and industrial automation with the cloud using IIoT principles in a cost-effective, safe, and reliable manner.

    Norvi IoT devices are such industrial controllers that support MQTT protocol.These programmable MQTT devices come with a variety of features that make them suitable for industrial automation and IoT solutions. These devices come equipped with digital and analog I/O, enabling them to detect digital logic states and analog inputs, depending on the choice of the model.

    After selecting a programmable MQTT Iot device like Norvi, only simple legwork has to be done by the users to establish the MQTT connection. Refer this detailed article on connecting the Norvi device to the IoT cloud platform Ubidots over MQTT protocol with step by step instructions.Moreover, setting up the Norvi devices only requires lesser wiring, which offers more flexibility to management of the device.

    RPI HMI Node-RED Introduction: Controlling Analog Inputs

    Example of RPI HMI NODE-RED integration is described in this article. NORVI has a set of node-red nodes that makes programming easy.

    Here is an example of using the Raspberry PI HMI Analog Input node for Node-RED. This node facilitates the control of NORVI-RPI-HMI analog inputs.

    The Raspberry HMI supports Node-Red programs. 

    HMI – ADC

    RPI HMI Node-RED

    The Analog Input Separation Node is designed to manage and process analog input signals efficiently. It’s particularly useful for working with sensors or devices that generate continuous analog signals, such as temperature sensors, light sensors, or pressure sensors.

    Inputs: Input HMI Analog Node

    Outputs: Integer or Double Analog Value of Selected Channel

    Configuration

    Channel: Channel Number

    Users can configure the node to handle specific analog inputs by selecting the appropriate settings within the node’s properties

    Analog Value: Raw ADC Value

    Output Value: Value Mapped for Raw ADC value specified in Raw ADC Value

    Decimal Point: Number of decimal points to round off (Max. 3)

    Users can enter the analog value and the output values to this node.

    HMI-ANALOG

    The Analog Read Node is used to initialize the analog module and read analog channels. When integrated with Analog Input Separation Nodes, it facilitates the independent monitoring and analysis of distinct analog input signals. This synergy enables users to precisely observe and evaluate individual values, contributing to a comprehensive understanding of the analog input data within the Node-RED environment.

    Inputs: Input TRUE once to initialize, the Boolean

    Outputs: All 8 channels are available as msg.AN0 – msg.AN7.

    To extract the output for individual channels use HMI ADC Node

    Example Program - RPI HMI NODE-RED integration

    Let’s create a simple example program using the RPI-HMI-ADC node and RPI-HMI-ANALOG node. When an input is provided, the dashboard will show the corresponding analog input value.

    Here, to display the program in the Node-RED dashboard, added a test node (CH5 & CH6) as a dashboard node.

    After configuring the program, the user interface of the RPI HMI should look like this,

    Analog Input 5 is active, but Analog Input 6 is inactive.

    Analog Input 6 is active, but Analog Input 5 is inactive.

    Hope readers got a clear understanding about how to use RPI HMI Node-RED integration for Controlling Analog Inputs.
