The benefits of wireless IIoT are undeniable, making it a key focus for companies seeking to gain a competitive edge in the increasingly connected and digital industrial world.
What is IIoT?
The term Industrial Internet of Things (IIoT) refers to the application of Internet of Things (IoT) technology in industrial settings. It involves the interconnection and communication between physical devices (such as industrial sensors and actuators), machinery, and systems used in various industries. IIOT enables the collection, analysis, and exchange of data with the purpose of optimizing industrial processes, increasing efficiency, and improving decision-making.
How Does IIOT Work?
IIoT operates through a network of interconnected devices and machines that communicate with each other and transmit data. However, retrieving the information from these in industrial environments is not always easy or possible.
Many IIoT companies do not provide full connectivity for true IIoT to take place. Industrial facilities are characterized as being harsh in terms of communication. Noise, vibration, rotation, humidity, and heat contribute to this being a very challenging task.
This is where IO-Link Wireless comes in.
By enabling real-time industrial cable-grade communication, it allows getting this information from the different components and machines, factory-wide. Essentially, it empowers IIoT and makes it a reality.
IIOT Implementation
The IIoT implementation process includes the deployment of sensors and other IIoT devices across industrial environments. These devices collect data related to various parameters, such as:
- Temperature
- Pressure
- Humidity
- Vibration
The collected data is then transmitted from the IO-Link Wireless Device to the IO-Link Wireless Master. From there, it moves to the PLC via OPC UA and other Industrial Ethernet protocols (such as Ethernet/IP, PROFINET, or EtherCAT), and via MQTT or OPC UA to cloud-based and on-premise applications. There, it’s stored and analyzed.
The configuration of the IO-Link Wireless system and the MQTT publishing is done via a designated IO-Link Wireless Software. As many machines use sensors and components manufactured by various vendors, it’s critical for the data-collecting ability to be vendor-agnostic, as in the case of IO-Link Wireless.
In the cloud, advanced analytics and machine learning algorithms are employed to process and interpret the collected data. These algorithms can identify patterns, detect anomalies, and generate actionable insights. The analyzed data is then presented to stakeholders in a meaningful way, often through dashboards or reports, enabling them to make data-driven decisions and optimize operations.
Additional machine optimization platforms may be integrated into the system to ensure maximum efficiency.
Advanced IIoT systems also leverage edge computing, where some data processing occurs at the device or Gateway level itself. This approach reduces latency and allows for faster decision-making in time-critical applications.
Edge computing is particularly useful in situations where a rapid response is required. This includes manufacturing processes and predictive maintenance scenarios.

Challenges of Adopting IIoT
While the potential benefits of IIoT are significant, there are several challenges that organizations face when implementing IIoT solutions. Though posing a threat to the implementation of IIoT solutions, these challenges are easily solved when implementing IO-Link Wireless into the process. Traditional challenges include:
Industrial IoT Security
Low-level IIoT systems introduce points of vulnerability, as more devices are connected to networks. Protecting sensitive data and ensuring the security of IIoT devices and networks is crucial. In addition to IT-level security measures which are implemented in industrial facilities,
IO-Link Wireless introduces several other precaution measures, such as Adaptive Frequency Hopping – where each transmission is being done in a previously unknown and random frequency, Authenticated Pairing Process with a unique ID, only predefined I/O data being exposed, and Cyclic Redundancy Checks (CRC).
Interoperability
IIoT involves the integration of diverse devices, sensors, and systems from multiple vendors. Ensuring seamless interoperability and data exchange between different components can be challenging.
Being a Universal Standard, IO-Link Wireless is interoperable with other vendors’ IO-Link and IO-Link Wireless products.
CoreTigo’s products are also compatible with Digital and Analog devices, enabling them to connect to virtually any device. In addition to this, IO-Link Wireless coexists with other wireless networks (such as Wi-Fi and BLE), thus allowing fluent and uninterrupted work throughout the facility.
Scalability
As IIoT deployments grow, managing and scaling the infrastructure becomes increasingly complex. Organizations need to plan for scalability from the outset, considering factors such as widespread connectivity, and allocating resources to support a vast amount of sensors and other devices.
IO-Link Wireless was specifically developed to ensure excellent performance in terms of low latency and high reliability, even when accommodating a significant number of devices.
