2. What is Industrial Automation?


Industrial automation, synonymous with factory automation, is the practice of controlling and monitoring industrial processes and machinery with computers and control systems, all with minimal human intervention. Systems typically comprise a variety of sensors, actuators, and control systems, networked together to control and monitor the processes and equipment in the factory. When properly implemented, industrial automation increases efficiency and reliability. This leads to cost reductions, safety enhancements, and quality improvements. Industrial automation can also help to minimize the environmental impact of a factory.

Various limitations hinder the efficiency of conventional industrial automation, such as increased maintenance and fixed systems with little flexibility. Industry 4.0 addresses these shortcomings, modifying existing automation to enable free flowing communication and smart connectivity across an open and scalable platform.

Modern industrial automation makes use of a variety of cutting-edge technologies, including the Industrial Internet of Things (IIoT), cloud computing, data analytics, 5G, cybersecurity, artificial intelligence (AI), and machine learning (ML). Equally important to the integration of modern digital technologies are the connectors that interconnect the system’s components.

3. Industry 4.0 and Smart Factory

Back to Top

Industry 4.0, often referred to as the Fourth Industrial Revolution, represents a paradigm shift that is characterized by the integration of computer-based algorithms and data-driven processes. A “smart factory” is a factory where machines are capable of communicating with each other, as well as with critical I/O nodes and junctures spanning whole distributed control systems and intelligent automation (IA) networks. Industry 4.0 enhances machine autonomy by applying its logic locally, on a machine-to-machine (M2M) basis.

product 1
Figure 2: Industrial Ethernet connectors provide optimum performance in harsh environments.

A smart factory accepts a variety of inputs from different sources, including data produced by sensors, instructions from controllers, and customer demands. Multiple technologies are combined in the implementation of a smart factory:

  • Industrial Internet of Things (IIoT): The IIoT is a network of interconnected industrial devices that enables data collection, analysis, and control to enhance operational efficiency, productivity, and decision-making. In a smart factory, machines, sensors, and other connected devices communicate with each other, exchanging real-time data. The collected data can be analyzed for predictive maintenance, maintaining asset health, and visibility of the supply chain. A robust communication network is required for IIoT implementation.
  • Artificial Intelligence (AI): Advanced analytics and algorithms with AI and machine learning (ML) help machines recognize patterns, optimize processes, and perform predictive analytics. Digital twins, software emulations of hardware environments, can perform simulations using test and real-time data. Digital twins also allow technicians to optimize performance remotely by visualizing layouts and workflows.
  • Robotics: In a smart factory, many automated tasks are performed by robots, the most modern of which offer repeatability and precision that humans cannot match. Collaborative robots (Cobots) are used to perform monotonous tasks, as well as dangerous tasks, helping factories streamline workflows while reducing the risk of physical injury. Similarly, autonomous mobile robots (AMRs) use machine vision to collect information from the factory floor and perform tasks like selecting components.
  • Cloud Computing: Cloud computing is a technology that delivers on-demand access to a shared pool of computing resources, such as servers, storage, and applications, over the internet, allowing users to scale and use these resources as needed. It facilitates cost-effective, scalable storage and processing of extensive data. With cloud computing, the provisioning, scaling, and maintenance of a computing infrastructure is offloaded to a cloud provider, allowing the company to focus on their primary business competencies.
  • Augmented Reality (AR) and Virtual Reality (VR): AR technology overlays digital information, such as images, videos, or 3D models, onto the real world, while VR immerses users in a computer-generated simulated environment. AR and VR are used in training and maintenance. AR/VR systems can display important information such as schematics, fault codes, or maintenance logs directly in the technician’s field of view, making diagnosing and fixing problems easier.

4. Power Management in Industry 4.0

Back to Top

The Power Infrastructure of Smart Factories

The convergence of automation, data analytics, and advanced technologies with Industry 4.0 presents new challenges and opportunities in power management and connectivity. With the presence of high voltages and high frequency signals, reliable and efficient power systems are a key requirement for smart factories.

In a modern power infrastructure, every aspect of the system is monitored by smart sensors, which transmit data in real-time. Parameters such as voltage, frequency, and harmonics are constantly monitored and analyzed. This data-driven approach is instrumental in predicting future power requirements. Diagnostic tools enable plant managers to maximize uptime and schedule preventative maintenance during predictable transitions. Real-time power monitoring also enables optimization of load balancing, reduced transmission losses, and improves the resilience and flexibility of the power distribution system.

Smart grids, a key component of Industry 4.0, make use of intelligent electronic devices, IoT sensors, real-time data analytics, and advanced connectivity to intelligently monitor and manage power distribution. Smart grids can predict energy generation and consumption patterns and enable the seamless integration of renewable energy sources.

Power Redundancy for Smart Factory Infrastructure

One of the goals of Industry 4.0 is uninterrupted operation; however, this requires the 24/7 availability of communication, control lines, and data centers. While data centers and critical computing units often have redundant backup systems, the power infrastructure must support redundant power as well. Power redundancy in a smart factory can be implemented through various technologies to ensure uninterrupted operations.

  • Uninterruptible Power Supplies (UPS): Deploying UPS units provides a short-term power backup during power outages or voltage fluctuations. They offer enough time for a controlled shutdown or for backup generators to come online.
  • Backup Generators: Backup generators, often fueled by diesel or natural gas, can provide a more extended source of power during prolonged outages. They are typically capable of running for an extended period and can sustain critical operations.
  • Dual Power Feeds: Ensure that the factory is connected to multiple power sources, such as separate grids or utility providers. In case of an outage in one source, the system can seamlessly switch to the other, providing continuous power.
  • Redundant Power Distribution: Implement dual power distribution paths to critical equipment and systems. This involves redundant power lines and circuitry, minimizing the risk of power disruption due to equipment failure or cable damage.
  • Energy Storage Systems: Energy storage solutions, like batteries, can store excess power during periods of low demand and release it during outages or peak demand, ensuring a continuous power supply.
  • Remote Monitoring and Control: Use smart monitoring and control systems to continuously monitor power quality and status. When an issue is detected, the system can automatically switch to the redundant power source or activate backup systems.
  • Predictive Maintenance: Implement predictive maintenance strategies to identify potential power system issues before they cause a failure. This helps prevent power disruptions and equipment damage.
  • Redundant Data Centers: If the smart factory relies heavily on cloud-based services or data processing, consider having redundant data centers with power redundancy to ensure the availability of critical data and applications.
  • Comprehensive Disaster Recovery Plan: Develop and regularly update a disaster recovery plan that includes procedures for handling power outages and ensures a smooth transition to redundant power sources. Test the plan periodically to ensure its effectiveness.

5. Connectivity in Industry 4.0

Back to Top

One of the key goals in Industry 4.0 is the self-adjusting assembly line, an assembly line where anomalies are automatically detected and corrected without human intervention. A self-adjusting assembly line relies on sensors and computer vision systems to identify issues and fix them before they become a problem. To realize this goal, an Industry 4.0 architecture requires seamless network connectivity for timely data access and delivery. Foundational networking technologies such as Ethernet, Single Pair Ethernet (SPE), and IO-Link are staples in Industry 4.0.

Industrial Ethernet

Industrial Ethernet is an extension of the traditional Ethernet networking standards commonly used in office and commercial settings, modified to meet the specific demands and challenges of industrial automation and control systems.

Key features and considerations of Industrial Ethernet include:

  • Robustness: Industrial Ethernet infrastructure is designed to withstand harsh conditions, including extreme temperatures, humidity, electromagnetic interference, and physical stress. This robustness ensures reliable communication in industrial environments such as factories, power plants, and warehouses.
  • Deterministic Communication: In many industrial applications, precise timing and low latency are critical. Industrial Ethernet protocols are often engineered to provide deterministic communication, where data transmission times are predictable and consistent. This is essential for real-time time-sensitive networking (TSN) and control systems.
  • Redundancy: Many Industrial Ethernet protocols support network redundancy to enhance reliability. Redundant paths and devices help maintain network availability in case of cable breaks or equipment failures.
  • Industrial Protocols: Several specialized protocols fall under the umbrella of Industrial Ethernet, including PROFINET, EtherNet/IP, Modbus TCP, and others. These protocols are tailored to meet the unique requirements of various industrial applications and equipment.
  • Device Compatibility: Industrial Ethernet is compatible with a wide range of industrial devices, including programmable logic controllers (PLCs), sensors, actuators, and human-machine interfaces (HMIs).
  • Integration with IT Networks: Industrial Ethernet networks are often designed to integrate with conventional IT networks, enabling data exchange between operational technology (OT) and information technology (IT) systems. This facilitates data analytics, remote monitoring, and centralized management of industrial processes.
  • Scalability: Industrial Ethernet networks can be easily scaled and expanded to accommodate the growing needs of an industrial facility. This scalability is crucial for accommodating new equipment or production lines.
  • Security: As with any network, security is a significant concern. Industrial Ethernet networks must implement security measures to protect against cyber threats and ensure the integrity and confidentiality of data.

Industrial Ethernet utilizes four cable pairs to achieve multi-gigabit throughputs, making the cable dimensions and associated connectors sizeable. For applications where multi-gigabit speeds are not required, Single Pair Ethernet (SPE) is a more compact, cost-effective solution.

Single Pair Ethernet (SPE)

Single Pair Ethernet (SPE) is a technology that simplifies and standardizes the use of Ethernet in industrial applications by reducing the number of cable pairs required for Ethernet communication. SPE uses only one pair of twisted cables (2 wires), reducing size and cost. SPE offers these features and advantages:

  • Simplification: SPE simplifies cabling infrastructure, making it easier to install, manage, and maintain, which is particularly valuable in challenging industrial and automotive environments.
  • Cost-Effective: Fewer wires and connectors translate to lower material and installation costs. This can be a significant benefit in large-scale industrial deployments.
  • Space-Efficient: SPE's reduced cable size and weight are particularly useful in applications where space constraints are a concern.
  • Versatility: SPE can support a range of communication protocols and data rates, making it suitable for various industrial and automotive applications, from sensors and actuators to cameras and controllers.
  • Robustness: SPE is designed to withstand harsh environmental conditions, including temperature extremes, vibration, and electromagnetic interference, making it suitable for challenging industrial and automotive settings.
  • Standardization: Industry organizations like the IEEE (Institute of Electrical and Electronics Engineers) and the TIA (Telecommunications Industry Association) have been working on standardizing SPE to ensure interoperability and widespread adoption.

SPE can transfer data and power simultaneously, with data transmission speed ranging from 10Mbps to 1Gbps and capable of transferring 52W of DC power up to a 1000m distance.

PROFINET

PROFINET is a widely used Industrial Ethernet communication protocol and networking standard that was designed to facilitate real-time communication and data exchange between a variety of industrial devices, including programmable logic controllers (PLCs), human-machine interfaces (HMIs), sensors, and drives. With a remarkable data exchange frequency of 1 µsec, PROFINET excels in precision applications that demand high-performance motion control.

PROFINET IO devices are classified into three categories: IO-Controllers, IO-Devices, and IO-Supervisors. IO-Controllers execute automation programs, communicating with IO-Devices via Ethernet. IO-Devices encompass distributed sensor and actuator devices linked to the IO Controller. IO-Supervisors include human-machine interfaces (HMIs), PCs, and other devices for commissioning, monitoring, or diagnostic analysis.

IO-Link

IO-Link is a point-to-point, bus-independent, serial digital communication protocol defined by international standard IEC 61131-9. IO-Link is designed to link sensors and actuators to PLCs. It enables bidirectional parameterization and diagnostic data transmission, where only binary states (ON/OFF) or analog signals were previously communicated. A system with IO-Link functionality can benefit from reduced downtime for maintenance and increased flexibility when configuring and reconfiguring.

An IO-Link system is comprised of two types of components: the "IO-Link Controller" and an "IO-Link Device" (sensor or actuator). IO-Link data exchange is controller-agent based; the IO-Link Controller communicates with IO-Link Devices, collecting data and transmitting it to the higher-level bus system. The controller can have multiple ports (usually four or eight), with each port connecting to a unique IO-Link device. The design of IO-Link enables it to work with existing industrial architectures, such as Fieldbus or Industrial Ethernet, providing connectivity to existing PLCs or HMIs.
