The Latest Technologies in IIoT


Industrial Artificial Intelligence (IAI)

Compared to AI, IAI is focused on applications in industrial fields, including manufacturing processes, packing processes, facility management, and storage management. IIoT-enabled devices enhance the development of IAI, with massive data from edge sensing devices and computing platforms. Like IPCs or IIoT cloud software, they are deployed to compute and analyze data and then predict breakdowns or high risk situations in the manufacturing process.

Edge Computing

Although cloud computing can be used to process a huge amount of data, over loading, high latency, and high power consumption can be side effects of of cloud computing. Unlike cloud computing, edge computing is more responsive and real-time. With edge computing, data could be instantly processed, computed, and analyzed by edge devices, the cloud only needs to process high-value or complicated data and information to optimize edge-to-cloud system efficiency.

For example, Advantech launched an intelligent edge DAQ gateway, WISE-750, an intelligent vibration sensing gateway embedded solutions for edge AI (machine learning) and vibration data acquisition. WISE-750 makes an intelligent vibration gateway ideally suited for monitoring the condition of the critical assets like CNC machine spindle status, elevator/ escalator system prognostics, precision linear slides, ball screws, bearings, and other equipment with mechanical moving parts.

Time-Sensitive Network (TSN)

The IoT effect has made deterministic communication more critical to industries such as automotive, manufacturing, utilities, and more. Determinism over standard Ethernet enables true real-time communication. That’s why we need time-sensitive networking. Four benefits of TSN are time synchronization, frame preemption, time aware shaper, and seamless redundancy.

Time synchronization

Synchronization means the technology of synchronized clocks enables machines to perform actions in the designated exact time, without time boundaries.

Frame preemption

In highly converged networks, higher priority traffic can be delayed by low priority frames leading to shutdowns and damage. Frame preemption allows a reduction of transmission latency for express traffic that can preempt low-priority packets.

Time aware shaper

Time-aware shaper is used to grant exclusive use to the Ethernet transmission for traffic classes requiring transmission guarantees that cannot be interrupted.

Seamless redundancy

Seamless redundancy offers multiple paths for redundancy. When the primary path fails, the duplicated copy path will arrive at the destination to guarantee no packet loss. Advantech launches the EKI-8500 series TSN Ethernet switch to make true real-time communication possible.

Machine to Machine (M2M) Communication

M2M refers to data interchange between machine to machine by using wired and wireless communication. Take the water pollution detection system as an M2M example, the water quality is detected by analyzing the parameters such as COD, PH, and particles. ADAM-6217 has an analog input to obtain parameters from sensors. It directly supports the MQTT protocol that can connect with the control center. So, when the water quality is not as it should be, ADAM-6217 will trigger an alarm on the system, and administrators in the control center will perform inspection activities.

Open Platform Communications Unified Architecture (OPC UA)

OPC UA is designed for industrial automation and is a free protocol for interchanging data between machines to machines, inside the machine, and machine to SCADA or management cloud platform. OPC UA simplifies M2M communication and decreases the communication gap between OT/IT. Before OPC UA, industrial communication protocols are possessed by different companies, such as PROFINET from Siemens PLC, EtherNet/IP from Rockwell Automation, and iQ-Link from Mitsubishi, etc. OPC UA instead offers an open connectivity across products, independent of the hardware or software platforms involved. OPC UA defines a standard way for sharing real-time data, historical data, and alarms & events, reducing integration and total life cycle cost for system implementation.

Message Queuing Telemetry Transport (MQTT)

MQTT is a publish/subscribe messaging protocol for constrained IoT devices in low-bandwidth, high-latency, or unreliable networks. MQTT is designed for IIoT applications because a huge amount of devices need to be connected, so having a lightweight message is beneficial to data transmission efficiency. MQTT and HTTP have the same bottom-layer system module - TCP/IP. Unlike HPPT accompanying a bunch of information on message headers, message headers of MQTT is simplified to have light data connecting bandwidth.

5G is the fifth-generation mobile network. 5G adopts shorter frequencies (millimeter waves) and are between 30GHz and 300 GHz. 5G delivers higher Gbps peak data speeds (20 Gbps), ultra-fast communication, extremely low latency, and a greater capacity of connected devices. 5G facilitates IIoT development to the next level, enabling preventive maintenance, edge computing, and huge amount of IIoT applications related to real-time monitoring and analysis.
