The power of combining OPC UA & MQTT Sparkplug

MQTT (Message Queuing Telemetry Transport) is a publish-subscribe based messaging protocol that is designed for lightweight, low-power devices and networks with limited bandwidth. The Sparkplug specification is a set of guidelines for using MQTT in industrial applications, such as those in the oil and gas, manufacturing, and utility industries.

Said industries are also currently using OPC UA as it provides a set of services and interfaces that allow for the discovery, access, and control of industrial devices and systems; as well as a wide range of data types and can be used for a variety of industrial applications, including process control, manufacturing, and building automation.

There are several advantages of using MQTT Sparkplug across industries, including:

  1. Low bandwidth requirements: MQTT is designed to be lightweight and efficient, making it well suited for use in networks with limited bandwidth. This makes it an ideal choice for use in remote and mobile devices and in environments where bandwidth is scarce.
  2. High reliability: MQTT is built on the TCP/IP stack, which provides a high degree of reliability and fault tolerance. This makes it well suited for use in industrial environments where uptime is critical and lost messages can have serious consequences.
  3. Easy integration: MQTT is a widely adopted protocol, and there are many libraries and tools available for various platforms and programming languages. This makes it easy to integrate MQTT into existing systems and applications.
  4. Support for multiple platforms: MQTT is supported on a wide range of platforms, including Windows, Linux, and iOS, making it easy to develop and deploy MQTT applications on the platform of your choice.
  5. Ease of scalability: MQTT is built on a publish-subscribe model, which makes it easy to add new devices and sensors to an existing network. This makes it well suited for use in environments where the number of devices and sensors is constantly changing.
  6. Improved security: MQTT supports various security features like SSL/TLS encryption and username/password authentication, which makes it secure to use in industrial environments.

While MQTT is a powerful and efficient protocol, it has some limitations that may make it less suitable for certain use cases. These limitations include limited Quality of Service options, limited security features, limited message size, limited support for non-textual data, limited support for one-to-many communication and no built-in message ordering.

MQTT Sparkplug was developed to provide a set of guidelines for using MQTT in industrial applications.

While MQTT is a widely adopted messaging protocol that is well-suited for use in a wide range of applications, it was originally designed for use in consumer and commercial applications. The industrial applications have a different set of requirements such as stricter security, more reliable communication, and more efficient data management.

The Sparkplug specification was developed to address these requirements by providing a set of guidelines for using MQTT in industrial applications. These guidelines include recommendations for data encoding, data management, security, and other aspects of using MQTT in industrial environments.

The main objective of Sparkplug is to provide a standard way of sending and receiving data with MQTT, that way making it easier to connect devices and systems from different vendors and to analyse the data in a consistent way. This can lead to a reduction in development time, cost and increase in interoperability.

Nevertheless, the Sparkplug specification does not compare with that of OPC (Open Platform Communication) Unified Architecture, a protocol widely used across all industries for its interoperability and security.

While OPC UA is a powerful and efficient standard, it has some limitations that may make it less suitable for certain use cases. These limitations include complexity, high development costs, high hardware requirements, limited scalability, limited security features, limited support for non-textual data, and limited support for mobile devices.

So why not combine both MQTT Sparkplug and OPC UA as both protocols make-up the weaknesses of one another?

We are combining OPC UA with MQTT Sparkplug for the following reasons:

  1. Improved interoperability: OPC UA is a widely adopted industrial communication standard, and MQTT is a widely adopted messaging protocol. By combining the two, organizations can achieve improved interoperability between different systems, devices, and platforms, making it easier to integrate and connect different parts of their industrial systems.
  2. Better scalability: OPC UA is designed for high-performance, high-throughput industrial communication, while MQTT is designed for low-power, low-bandwidth devices and networks. By combining the two, organizations can achieve better scalability and support a wider range of devices and sensors.
  3. Enhanced security: OPC UA provides advanced security features, such as secure communication and data encryption, while MQTT provides lightweight security features, such as SSL/TLS encryption and username/password authentication. By combining the two, organizations can achieve enhanced security for their industrial systems.
  4. Greater flexibility: OPC UA is a flexible standard that supports a wide range of industrial applications, while MQTT is a flexible protocol that supports multiple platforms and programming languages. By combining the two, organizations can achieve greater flexibility in their industrial systems and can more easily adapt to changing requirements.
  5. Improved data management: OPC UA provides a rich set of data models, which allows for precise and efficient data management. MQTT Sparkplug provides a set of guidelines for using MQTT in industrial applications, which allows for precise and efficient data management for the devices and systems that use MQTT.

Our Universal MQTT Broker is assisting our clients in simultaneously boosting interoperability and security by combining OPC UA with MQTT Sparkplug to achieve, better scalability, enhanced security, greater flexibility, and improved data management in their industrial systems.
