MQTT Industrial Telemetry with 4G Cellular Communication

The GRD-MQ-4G product family provides a comprehensive solution for Industrial Telemetry, taking advantage of the MQTT protocol, highly recognized in the context of Industry 4.0

• Works like a conventional MQTT node, to connect with a Broker
• Establishes a direct connection with the MQTT Broker over the 4G network
• Allows remote configuration from the Broker.
• Supports TLS 1.2 encryption


MQTT INTEGRATED ON EXEMYS DEVICES

Support for Encrypted Connections in MQTTS with Certificates
Exemys products that support the MQTT protocol are designed to ensure communications security. They offer support for encrypted connections in MQTTS (MQTT over TLS/SSL), using certificates to authenticate and encrypt the transmitted data. This additional layer of security is essential in environments where confidentiality and data integrity are critical.

Tests carried out with AWS and Azure
Exemys products have undergone rigorous interoperability testing with leading cloud services such as AWS (Amazon Web Services) and Microsoft's Azure. These tests ensure seamless and reliable integration with the most widely used cloud platforms in the industry, allowing users to take full advantage of the cloud's capabilities for data management and analysis.

Compatibility with the Kepserver OPC Server using the MQTT Driver
Exemys products are fully compatible with the OPC Server Kepserver through the MQTT driver. This facilitates the integration of Exemys devices in environments that use the OPC-UA standard, providing transparent and efficient communication between IoT devices and industrial control systems.

    PROGRAMMING LOGIC USING TEXT SCRIPTS


    What is a Script?

    A Script is a file with orders that once loaded on to the GRD, is interpreted and executed.
    Operations performed by a Script: The Script describes what operations should be executed by the device, for example:

  • Math Operations
  • Binary Logic Operations
  • Date and Time Operations
  • Working with Timers
  • Read Analog variables
  • Records of Variables
  • Digital I/O Read/Write
  • Sending and receiving SMS
  • Interpretation of data from the serial port

  • WITS Serial

    Computer Access Programming Using the WITS Protocol
    Implement access to the computer, using the WITS protocol through a simple SCRIPT. This protocol is widely recognized and used in telemetry devices.
