What is IIoT?

IIoT promises to revolutionize manufacturing by enabling the acquisition and accessibility of far greater amounts of data, at far greater speeds.

The Industrial Internet of Things (IIoT)

What is it and How Will it Affect Manufacturing?

The IIoT is part of a larger concept known as the Internet of Things (IoT). The IoT is a network of intelligent computers, devices, and objects that collect and share huge amounts of data. The collected data is sent to a central Cloud-based service where it is aggregated with other data and then shared with end users in a helpful way. The IoT will increase automation in homes, schools, stores, and in many industries.


The application of the IoT to the manufacturing industry is called the IIoT (or Industrial Internet or Industry 4.0). The IIoT will revolutionize manufacturing by enabling the acquisition and accessibility of far greater amounts of data, at far greater speeds, and far more efficiently than before. A number of innovative companies have started to implement the IIoT by leveraging intelligent, connected devices in their factories.

What are the Benefits of IIoT?

The IIoT can greatly improve connectivity, efficiency, scalability, time savings, and cost savings for industrial organizations. Companies are already benefitting from the IIoT through cost savings due to predictive maintenance, improved safety, and other operational efficiencies. IIoT networks of intelligent devices allow industrial organizations to break open data silos and connect all of their people, data, and processes from the factory floor to the executive offices. Business leaders can use IIoT data to get a full and accurate view of how their enterprise is doing, which will help them make better decisions.

IIoT Protocols

One of the issues encountered in the transition to the IIoT is the fact that different edge-of-network devices have historically used different protocols for sending and receiving data. While there are a number of different communication protocols currently in use, such as OPC-UA, the Message Queueing Telemetry Transport (MQTT) transfer protocol is quickly emerging as the standard for IIoT, due to its lightweight overhead, publish/subscribe model, and bidirectional capabilities. You can read more about MQTT.

Challenges of the IIoT

Interoperability and security are probably the two biggest challenges surrounding the implementation of IIoT. As technology writer Margaret Rouse observes, “A major concern surrounding the Industrial IoT is interoperability between devices and machines that use different protocols and have different architectures.” Ignition is an excellent solution for this since it is cross-platform and built on open-source, IT-standard technologies.


Companies need to know that their data is secure. The proliferation of sensors and other smart, connected devices has resulted in a parallel explosion in security vulnerabilities. This is another factor in the rise of MQTT since it is a very secure IIoT protocol.

The Future of the IIoT

The IIoT is widely considered to be one of the primary trends affecting industrial businesses today and in the future. Industries are pushing to modernize systems and equipment to meet new regulations, to keep up with increasing market speed and volatility, and to deal with disruptive technologies. Businesses that have embraced the IIoT have seen significant improvements to safety, efficiency, and profitability, and it is expected that this trend will continue as IIoT technologies are more widely adopted.

The Ignition IIoT solution greatly improves connectivity, efficiency, scalability, time savings, and cost savings for industrial organizations. It can unite the people and systems on the plant floor with those at the enterprise level. It can also allow enterprises to get the most value from their system without being constrained by technological and economic limitations. For these reasons and more, Ignition offers the ideal platform for bringing the power of the IIoT into your enterprise.

What is MQTT?

MQTT is a machine-to-machine (M2M) data transfer protocol that is quickly becoming the leading messaging protocol for the Industrial Internet of Things (IIoT).

What is MQTT and Why is it Ideal for SCADA?

While there are currently a number of competing IIoT technologies and protocols in play, the extremely lightweight overhead (2-byte header), publish/subscribe model, and bidirectional capabilities of MQTT are uniquely suited to meet the demands of industrial control systems.


The newest version, MQTT Version 3.1.1, is an OASIS standard that is open and royalty-free. (OASIS is the Organization for the Advancement of Structured Information Standards, an international consortium that promotes the adoption of product-independent standards for information formats.)

What are the Advantages of MQTT?

The MQTT protocol allows your SCADA system to access IIoT data. MQTT brings many powerful benefits to your process:

·         Distribute information more efficiently

·         Increase scalability

·         Reduce network bandwidth consumption dramatically

·         Reduce update rates to seconds

·         Very well-suited for remote sensing and control

·         Maximize available bandwidth

·         Extremely lightweight overhead

·         Very secure with permission-based security

·         Used by the oil-and-gas industry, Amazon, Facebook, and other major businesses

·         Saves development time


·         Publish/subscribe protocol collects more data with less bandwidth compared to polling protocols

Why Was MQTT Created?

MQTT was created with the goal of collecting data from many devices and then transporting that data to the IT infrastructure. It is lightweight, and therefore ideal for remote monitoring, especially in M2M connections that require a small code footprint or where network bandwidth is limited.


MQTT was invented in 1999 by Dr. Andy Stanford-Clark and Arlen Nipper. Co-inventor Arlen Nipper is the president of Cirrus Link Solutions.

How Does MQTT Work?

MQTT is a publish/subscribe protocol that allows edge-of-network devices to publish to a broker. Clients connect to this broker, which then mediates communication between the two devices. Each device can subscribe, or register, to particular topics. When another client publishes a message on a subscribed topic, the broker forwards the message to any client that has subscribed.

MQTT is bidirectional, and maintains stateful session awareness. If an edge-of-network device loses connectivity, all subscribed clients will be notified with the “Last Will and Testament” feature of the MQTT server so that any authorized client in the system can publish a new value back to the edge-of-network device, maintaining bidirectional connectivity.

The lightweightness and efficiency of MQTT makes it possible to significantly increase the amount of data being monitored or controlled. Prior to the invention of MQTT, approximately 80% of data was being left at remote locations, even though various lines of business could have used this data to make smarter decisions. Now MQTT makes it possible to collect, transmit, and analyze more of the data being collected.

Unlike the usual poll/response model of many protocols, which tend to unnecessarily saturate data connections with unchanging data, MQTT’s publish/subscribe model maximizes the available bandwidth.

Who Uses MQTT?

MQTT was originally developed for the low-bandwidth, high-latency data links used in the oil and gas industry. However, MQTT is now used in many applications beyond oil and gas — from controlling smart lighting systems to the Facebook Messenger application. Amazon Web Services recently announced that Amazon Internet of Things (IoT) is based on MQTT, as well. Overall, MQTT appears to be the protocol best suited for the control systems used by industrial organizations, and we can expect that its rapid rate of adoption will only increase in the future.
