Industrial automation communication connects PLCs, sensors, drives, and SCADA via protocols like PROFINET, Modbus, OPC UA, and Ethernet/IP, enabling deterministic control, interoperability, diagnostics, safety, and IIoT data across electrical systems and networks.

What Is Industrial Automation Communication?

Networked real-time data exchange between PLCs, sensors, HMIs, and SCADA using standardized industrial protocols.

✅ Supports deterministic Ethernet (TSN) and legacy fieldbus integration

✅ Enables real-time control, diagnostics, and predictive maintenance

✅ Interoperates via PROFINET, Modbus, EtherNet/IP, and OPC UA

In the early 20th century, process control systems and the manufacturing systems were designed based primarily on the mechanical technology and with analog devices. After the period, the pneumatic control technology and the hydraulic power were introduced. The pneumatic control technology made it possible to control remote systems by a centralized control system. These technologies are still very common.

At the beginning of 1960, a digital computer was for the first time really applied as a digital controller. The term direct digital control (DDC) was used to emphasize that the computer directly controls the process. In the 1960s, the application of a minicomputer was still a fairly expensive solution for many control problems. In the meantime, programmable logic controller (PLC) was developed and it replaced the conventional, relay-based controller, having relatively limited control functions. In addition, many technologies were developed for machine tools and discrete production processes. The numerically controlled (NC) machine tool became to be controlled by computers and the robot was developed in this period.

With the more widespread use of digital computers and the associated technologies, industrial communication networks became to be developed with or converted to digital transmission. Proprietary digital communication networks for industrial use started in the 1960s as computers for automation systems were first linked together.

In mid 70s, the first distributed computer control system (DCCS) was announced by Honeywell as a hierarchical control system with a large number of microprocessors. Since its introduction in mid 1970s, the concept of the DCCS spread widely in many industrial automation systems such as power plant control systems, manufacturing systems, etc. The installation of distributed control systems in the newly planned plants or replacement of existing analogue or centralized control systems is presently a common decision of enterprise management. In sectors like power generation, advanced energy management strategies leverage DCS data to optimize load balancing and maintenance planning across units.

The use of local area networks to interconnect computers and automation devices within an industrial automation system has become popular since 1980. The high capacity low cost communication offered by local area networks has made distributed computing a reality, and many automation services. The 

As deployments expanded, many organizations realized that the benefits of industrial networks include lower downtime, scalable integration, and improved data visibility across operations.

industrial automation systems are often implemented as an open distributed architecture with communication over digital communication networks. Achieving high availability requires the right mix of industrial network components such as managed switches, protocol gateways, and ruggedized edge controllers.

It is now common for users connected to a local area network to communicate with computers or automation devices on other local area networks via gateways linked by a wide area network. Similar architectures now extend into transportation, where smart city automated level crossings depend on resilient networking to coordinate sensors, barriers, and central oversight.

As the industrial automation systems becomes large and the number of automation devices increases, it has become very important for industrial automation to provide standards which make it possible to interconnect many different automation devices in a standard way. Considerable international standardization efforts have been made in the area of local area networks. The Open Systems Interconnection (OSI) standards permit any pair of automation devices to communicate reliably regardless of the manufacturer. To plan these interoperable systems, designers often reference hierarchical levels in industrial networks to align plant-floor operations with supervisory and enterprise layers.

Industrial networks span many manufacturing applications. Standard industrial networks using digital communication technologies cover a wide range of manufacturing applications. In many applications, the types of devices and performance determine the type of network. Contrast the needs of two devices -- a proximity sensor used on a conveyor belt compared to a control valve used in a petroleum refinery. The proximity sensor has a single function - to transmit a Boolean on/off signal indicating the proximity of an object. We can accommodate this signal in a few bits of data. Diagnostic information from the sensor is probably limited to a single "health" indicator, which again requires very little data. However, we can expect the control valve to provide very sophisticated control functions and diagnostics, such as number of cycles since last servicing, packing friction, and ambient operating temperature. These parameters can be extremely critical in an environment such as a refinery -- failures can result in dangerous situations and costly downtime. Clearly, the proximity sensor and the control valve have different network requirements. Therefore, different types of industrial networks must address a variety of different needs. We must select the right network to address our specific application requirements.

What is an Industrial Network? By definition, an industrial network requires geographical distribution of the physical measurement I/O and sensors or functional distribution of applications. Most industrial networks transfer bits of information serially. Serial data transfer has the advantage of requiring only a limited number of wires to exchange data between devices. With fewer wires, we can send information over greater distances. Because industrial networks work with several devices on the same line, it is easier to add a new device to existing systems. Comparing fieldbus, Ethernet, and wireless backbones, understanding transmission methods in industrial networks helps engineers match latency, bandwidth, and environmental constraints.

To make all this work, our network must define a set of rules -- a communication protocol -- to determine how information flows on the network of devices, controllers, PCs, and so on. With improved communication protocols, it is now possible to reduce the time needed for the transfer, ensure better data protection, and guarantee time synchronization, and real-time deterministic response in some applications. Industrial networks also ensure that the system sends information reliably without errors and securely between nodes on the network.

For the lower level communication network for industrial automation, the industrial local area network solutions such as MAP are too expensive and/or do not reach the required short response times, depending on the application. The fieldbuses have been, therefore, developed to meet these requirements, and many efforts are now being made to make fieldbus standards for industrial automation applications. The same field-level connectivity principles underpin a modern building automation system where HVAC, lighting, and security integrate reliably across facilities.

Energy management enhances power systems via smart grid controls, demand response, load forecasting, SCADA, and IoT sensors to improve energy efficiency, peak shaving, power quality, and renewable integration across industrial and utility operations.

What Is Energy Management?

Energy management is the control of electrical loads and assets to optimize efficiency, reliability and cost.

✅ Predictive load forecasting and peak shaving strategies

✅ SCADA/EMS integration with IoT sensors and analytics

✅ Demand response, power quality, and DER coordination

Energy management (EM) is a crucial practice today, as it helps businesses and individuals reduce their carbon footprint, save money, and contribute to a more sustainable future. By incorporating key elements such as efficiency, demand response, building automation, audits, smart grid technology, HVAC optimization, conservation, renewable energy, monitoring, and analytics, a comprehensive EM program can lead to significant savings and environmental benefits. As the world continues to face the challenges of climate change and dwindling resources, EM will remain an indispensable tool for creating a more sustainable and efficient future. For organizations starting out, an energy management program can provide a structured roadmap for setting goals and tracking performance.

Energy management is crucial for several reasons. First, it helps reduce carbon emissions and the overall environmental impact of energy use. Second, it saves money by lowering costs and making facilities more energy efficient. Third, EM practices contribute to businesses and organizations' long-term sustainability and competitiveness. Modern energy management systems offer centralized dashboards and automated alerts that help sustain these gains over time.

Building automation is one of the primary ways energy management systems improve efficiency in buildings. These systems utilize sophisticated technology to control and optimize energy use in various systems, such as heating, ventilation, air conditioning (HVAC), lighting, and security. By automating these systems, buildings can operate more efficiently and effectively, reducing waste and saving on costs. For broader context, guides on building automation fundamentals can help teams understand integration points with HVAC and lighting controls.

Energy management in industrial facilities requires a combination of best practices, including implementing EM systems, regular audits, and data analytics. By monitoring and analyzing data, asset managers can identify areas of inefficiency, implement targeted improvements, and track the success of their energy management strategies. As operations mature, adopting advanced energy management practices can unify analytics, forecasting, and optimization across multiple facilities.

Renewable energy sources, such as solar, wind, and geothermal, can be integrated into energy management systems to improve sustainability further and reduce reliance on fossil fuels. For example, a facility may use solar panels to generate electricity during peak sunlight hours, reducing the need for grid-supplied energy and reduce energy costs. Additionally, renewable energy can be used with energy storage systems to provide backup power during high demand or grid outages. Well-designed building energy management systems coordinate on-site renewables with storage and loads to maximize self-consumption and resilience.

An effective EM strategy comprises several key components, including a thorough understanding of use, a commitment to continuous improvement, and a focus on energy-efficient technologies and practices. For example, businesses can implement energy-saving measures, such as retrofitting lighting systems with energy-efficient LEDs, upgrading HVAC systems to more efficient models, and improving building insulation to minimize heat loss. Upgraded energy management controls enable granular scheduling, sensor-driven setpoints, and measurement and verification to prove savings.

Smart grids and demand response play a critical role in EM by enabling a more flexible and responsive approach. Smart grids use advanced technology and real-time data to optimize electricity generation, distribution, and energy consumption. On the other hand, demand response programs incentivize consumers to reduce or shift their energy use during periods of high demand, helping to balance the grid and lower overall costs. When paired with a capable building automation system, demand response signals can trigger coordinated load shifts with minimal occupant disruption.

Audits are an essential part of energy management, as they provide a comprehensive assessment of a building's performance and identify opportunities for improvement. During an audit, an EM professional evaluates the consumption of a facility, typically an office building or industrial plant, and recommends cost-effective measures to reduce use and costs. These recommendations may include upgrading equipment, implementing energy-efficient practices, and addressing inefficiencies in the building's design or operations.

Hierarchical Levels Industrial Networks align device, control, and enterprise layers across PLCs, SCADA, MES, and ERP, using fieldbus, Ethernet/IP, and Profinet to ensure deterministic control, real-time data, cybersecurity, and scalable OT-IT integration.

What Are Hierarchical Levels Industrial Networks?

Layered OT networks linking devices, control, and enterprise systems for real-time, deterministic, secure automation.

✅ Defines device, control, and enterprise layers in OT/ICS

✅ Maps PLCs, HMIs, drives, and sensors to appropriate network tiers

✅ Ensures determinism, redundancy, and EMC-compliant cabling practices

The industrial automation systems can be very complex, and it is usually structured into several hierarchical levels. Each of the hierarchical level has an appropriate communication level, which places different requirements on the communication network. Figure 1.1 shows an example of the hierarchy of an industrial automation system. For a broader overview of protocols and trends, industrial automation communication resources explain how hierarchy influences network design across levels.

Industrial networks may be classified in several different categories based on functionality - field-level networks (sensor, actuator or device buses), control-level networks (control buses) and information-level networks. Organizations adopt these layers to gain measurable efficiencies, and the benefits of industry networks include improved interoperability, uptime, and lifecycle support.

We primarily use sensor and actuator buses to connect simple, discrete devices with limited intelligence, such as a photo-eye, limit switch, or solenoid valve, to controllers and computers. Sensor buses such as ASI and CAN are designed so information flow is reduced to a few bits and the cost per node is a critical factor. Selecting cabling, interfaces, and gateways depends on understanding industrial network components that shape reliability, diagnostics, and scalability.

Field level

The lowest level of the automation hierarchy is the field level, which includes the field devices such as actuators and sensors. The elementary field devices are sometimes classified as the element sublevel. The task of the devices in the field level is to transfer data between the manufactured product and the technical process. The data may be both binary and analogue. Measured values may be available for a short period of time or over a long period of time.

For the field level communication, parallel, multiwire cables, and serial interfaces such as the 20mA current loop has been widely used from the 

past. The serial communication standards such as RS232C, RS422, and RS485 are most commonly used protocols together with the parallel communication standard IEEE488. Those point-to-point communication methods have evolved to the bus communication network to cope with the cabling cost and to achieve a high quality communication. Comparisons of copper, fiber, and wireless media, along with signaling and topology choices, are covered in transmission methods for industrial networks to help match performance with environmental constraints.

Field-level industrial networks are a large category, distinguished by characteristics such as message size and response time. In general, these networks connect smart devices that work cooperatively in a distributed, time-critical network. They offer higher-level diagnostic and configuration capabilities generally at the cost of more intelligence, processing power, and price. At their most sophisticated, fieldbus networks work with truly distributed control among intelligent devices like FOUNDATION Fieldbus. Common networks included in the devicebus and fieldbus classes include CANOpen, DeviceNet, FOUNDATION Fieldbus, Interbus-S, LonWorks, Profibus-DP, and SDS.

These characteristics also underpin infrastructure applications such as rail crossings, where distributed sensors and controllers coordinate safety logic, as seen in smart city automated level crossings that rely on deterministic messaging.

Nowadays, the fieldbus is often used for information transfer in the field level. Due to timing requirements, which have to be strictly observed in an automation process, the applications in the field level controllers require cyclic transport functions, which transmit source information at regular intervals. The data representation must be as short as possible in order to reduce message transfer time on the bus.

Control Level

At the control level, the information flow mainly consists of the loading of programs, parameters and data. In processes with short machine idle times and readjustments, this is done during the production process. In small controllers it may be necessary to load subroutines during one manufacturing cycle. This determines the timing requirements. It can be divided into two: cell and area sublevels.

Cell Sublevel

For the cell level operations, machine synchronizations and event handlings may require short response times on the bus. These real-time requirements are not compatible with time-excessive transfers of application programs, thus making an adaptable message segmentation necessary.

In order to achieve the communication requirements in this level, local area networks have been used as the communication network. After the introduction of the CIM concept and the DCCS concept, many companies developed their proprietary networks for the cell level of an automation system. The Ethernet together with TCP/IP (transmission control protocol/internet protocol) was 

accepted as a de facto standard for this level, though it cannot provide a true real-time communication. Similar patterns appear in buildings, where building automation systems integrate HVAC, lighting, and security over IP while reserving real-time tasks for specialized buses.

Many efforts have been made for the standardization of the communication network for the cell level. The IEEE standard networks based on the OSI layered architecture were developed and the Mini-MAP network was developed in 1980s to realize a standard communication between various devices from different vendors. Some fieldbuses can also be used for this level.

Area sublevel

The area level consists of cells combined into groups. Cells are designed with an application-oriented functionality. By the area level controllers or process operators, the controlling and intervening functions are made such as the setting of production targets, machine startup and shutdown, and emergency activities.

We typically use control-level networks for peer-to-peer networks between controllers such as programmable logic controllers (PLCs), distributed control systems (DCS), and computer systems used for human-machine interface (HMI), historical archiving, and supervisory control. We use control buses to coordinate and synchronize control between production units and manufacturing cells. Typically, ControlNet, PROFIBUS-FMS and (formerly) MAP are used as the industrial networks for controller buses. In addition, we can frequently use Ethernet with TCP/IP as a controller bus to connect upper-level control devices and computers.

Information level

The information level is the top level of a plant or an industrial automation system. The plant level controller gathers the management information from the area levels, and manages the whole automation system. At the information level there exist large scale networks, e.g. Ethernet WANs for factory planning and management information exchange. We can use Ethernet networks as a gateway to connect other industrial networks. At this level, analytics platforms often drive energy KPIs, and advanced energy management strategies leverage network data for optimization and demand response.

What is Building Automation?

Building automation is crucial in creating sustainable, efficient, and comfortable living and working environments. By incorporating advanced technologies like IoT and data analytics, building automation systems can optimize energy consumption, enhance occupant comfort, and promote cost-effective building management. As technology continues to evolve, building automation's potential benefits and applications are set to expand further, making it an essential aspect of modern building design and operation. For foundational context on how organizations plan, monitor, and optimize consumption, consult this energy management primer that aligns with modern building objectives.

Building automation refers to the centralized building control system for various systems, such as heating, ventilation, air conditioning (HVAC), lighting, security systems, and other related subsystems. The main objective of a building automation system (BAS) is to optimize energy consumption, enhance the comfort of occupants, and ensure that the building operates efficiently and cost-effectively. A concise primer on system architectures and typical functions is provided in the building automation system overview, which clarifies scope and capabilities.

A BAS comprises interconnected components and subsystems, including sensors, controllers, and user interfaces. Sensors measure temperature, humidity, and occupancy, while controllers use this information to regulate various building systems, such as air conditioning and lighting. User interfaces enable facility managers and authorized personnel to monitor and adjust system settings as needed. To understand how setpoints, scheduling, and feedback loops are orchestrated, explore energy management controls guidance that illustrates controller strategies.

One of the primary benefits of building automation is its ability to reduce energy consumption and enhance energy efficiency for building owners. A BAS can optimize energy usage and minimize waste by continuously monitoring and adjusting building systems based on real-time data. For example, automated control of lighting and HVAC systems can help maintain optimal temperature and lighting levels while conserving energy when spaces are unoccupied. This leads to lower utility bills and a reduced carbon footprint. These practices are often formalized within building energy management systems frameworks that standardize analytics and reporting.

Building automation also promotes cost-effective building management system by reducing maintenance and operational costs. A well-designed BAS can detect and address potential issues before they escalate into expensive problems, allowing facility managers to maintain building systems and extend their life expectancy proactively. Additionally, building automation control can help maximize the productivity and comfort of building occupants by maintaining a consistent and pleasant indoor environment. When aligned with enterprise objectives, broader energy management systems can integrate with BAS workflows to coordinate maintenance and savings.

The Internet of Things (IoT) plays a significant role in the development and advancement of building automation. IoT output devices and sensors provide a wealth of real-time data that can be analyzed and leveraged to enhance building performance further. This integration allows for more precise control and monitoring of building systems and the developing of new, innovative energy management and conservation solutions. This data-driven approach enables advanced energy management techniques that support predictive control and optimization.

What is Building Automation?

Building automation is also closely linked to facility management, as both disciplines aim to optimize the operation and maintenance of building systems. By integrating building automation with facility management software, facility managers can monitor and control various building systems more effectively, streamline maintenance tasks, and make data-driven decisions to optimize building performance. Interoperability relies on reliable industrial automation communication methods that allow platforms to share telemetry securely.

The future of building automation technology holds exciting possibilities, including the development of increasingly intelligent and interconnected systems. In addition, advances in artificial intelligence, machine learning, and data analytics will enable BAS to become even more efficient and responsive to changing conditions, resulting in greater energy savings and reduced environmental impact.

Industrial network components enable reliable Ethernet, fieldbus, and IIoT connectivity across PLCs, HMIs, drives, and sensors, using managed switches, routers, protocol gateways, and cybersecurity firewalls for real-time control, redundancy, and deterministic data.

What Are Industrial Network Components?

Hardware like switches, routers, gateways, and I/O modules that link PLCs and sensors for secure, deterministic control.

✅ Managed Ethernet switches enforce VLANs, QoS, and ring redundancy

✅ Gateways bridge Modbus, PROFIBUS, and PROFINET protocols

Industrial Network Components

In larger industrial and factory networks, a single cable is not enough to connect all the network nodes together. We must define network topologies and design networks to provide isolation and meet performance requirements. In many cases, because applications must communicate across dissimilar networks, we need additional network equipment. The following are various types of network components and topologies:

For an overview of how devices exchange data across varied protocols, see the guide on industrial automation communication best practices for plant networks.

• Repeaters -- a repeater, or amplifier, is a device that enhances electrical signals so they can travel greater distances between nodes. With this device, we can connect a larger number of nodes to the network. In addition, we can adapt different physical media to each other, such as coaxial cable to an optical fiber.
• Router -- a router switches the communication packets between different network segments, defining the path.
• Bridge -- with a bridge, the connection between two different network sections can have different electrical characteristics and protocols. A bridge can join two dissimilar networks and applications can distribute information across them.
• Gateway -- a gateway, similar to a bridge, provides interoperability between buses of different types and protocols, and applications can communicate through the gateway.

In planning placement of routers, bridges, and gateways, it's useful to map the hierarchical levels of industrial networks across field, control, and enterprise layers.

Network Topology

Industrial systems usually consist of two or more devices. As industrial systems get larger, we must consider the topology of the network. The most common network topologies are the bus, star, or a hybrid network that combines both. Three principal topologies are employed for industrial communication networks: star, bus, and ring as shown in Figure 3. Understanding media choices and signaling options is essential, and the overview of transmission methods for industrial networks explains tradeoffs between copper, fiber, and wireless.

A star configuration contains a central controller, to which all nodes are directly connected. This allows easy connection for small networks, but additional controllers must be added once a maximum number of nodes are reached. The failure of a node in a star configuration does not affect other nodes. The star topology has a central hub and one or more network segment connections that radiate from the central hub. With the star topology, we can easily add further nodes without interrupting the network. Another benefit is that failure of one device does not impair communications between any other devices in the network; however, failure of the central hub causes the entire network to fail. These design choices tie directly to the benefits of industrial networks that improve scalability and resilience.

In the bus topology, each node is directly attached to a common communication channel. Messages transmitted on the bus are received by every node. If a node fails, the rest of the network continues in operation as long as the failed node does not affect the media. This shared medium approach is often integrated under a facility's building automation system where distributed controllers share status and control signals.

In the ring topology, the cable forms a loop and the nodes are attached at intervals around the loop. Messages are transmitted around the ring passing the nodes attached to it. If a single node fails, the entire network could stop unless a recovery mechanism is not implemented.

In transportation settings like automated level crossings environments, deterministic performance and failover are crucial for safety.

For most networks used for industrial applications, we can use hybrid combinations of both the bus and star topologies to create larger networks consisting of hundreds, even thousands of devices. We can configure many popular industrial networks such as Ethernet, FOUNDATION Fieldbus, DeviceNet, Profibus, and CAN using hybrid bus and star topologies depending on application requirements. Hybrid networks offer advantages and disadvantages of both the bus and star topologies. We can configure them so failure of one device does not put the other devices out of service. We can also add to the network without impacting other nodes in the network. Hybrid architectures also support advanced energy management strategies that balance load and reduce downtime during maintenance.

An energy management program is increasingly important in industrial, commercial, and institutional power systems due to growing concerns about energy efficiency, costs, and environmental impact. Implementing an effective energy management program (EMP) can help businesses save money, reduce their carbon footprint, and achieve sustainability goals. This article will delve into the key components of an energy management program and discuss how it can benefit businesses in various sectors. To understand the broader scope of best practices, resources on energy management provide context for implementation across sectors.

An effective EMP typically includes energy efficiency measures, energy audits, energy conservation strategies, building automation, energy monitoring, demand response initiatives, sustainable energy policies, and the implementation of EM systems. Facility management plays a crucial role in ensuring the success of such programs. For teams new to these concepts, a concise primer on what is building automation can help align terminology and roles.

One of the primary goals of an energy management program is to increase energy efficiency. This can be achieved by identifying areas where energy is wasted and implementing measures to reduce energy consumption. For instance, energy-efficient lighting, heating, and cooling systems can significantly reduce energy usage in commercial and institutional buildings. Incorporating energy management controls enables precise scheduling and setpoint optimization for measurable savings.

Energy audits are a vital component of an EMP, as they help identify areas of energy waste and provide recommendations for improving energy efficiency. These audits involve a thorough assessment of a facility's energy consumption patterns and equipment performance, which can lead to the implementation of cost-effective energy-saving measures. Audit findings are often operationalized through energy management systems that track KPIs and verify results.

Energy conservation strategies are another crucial aspect of an energy management program. These strategies aim to minimize energy consumption without compromising operational efficiency. Examples of energy conservation measures include optimizing equipment performance, implementing energy-saving operational procedures, and promoting energy-conscious behavior among employees. Modern analytics and automation in advanced energy management support continuous improvement in conservation programs.

Building automation systems play a significant role in energy management programs by allowing for the centralized control and monitoring of various building systems, such as HVAC, lighting, and security. These systems can help optimize energy usage by automatically adjusting settings based on factors like occupancy, time of day, and weather conditions. Selecting an open-protocol building automation system improves interoperability with meters and sub-systems for broader control.

Energy monitoring is essential for tracking the effectiveness of an energy management program. By continuously measuring and analyzing energy consumption data, businesses can identify trends, pinpoint inefficiencies, and implement corrective measures to optimize energy use further. Many organizations centralize this function within building energy management systems to visualize trends and trigger alerts.

Demand response initiatives can help businesses in industrial, commercial, and institutional power systems participate in energy markets by adjusting their energy consumption in response to market signals, such as electricity price fluctuations or grid reliability issues. This can help businesses reduce energy costs and support grid stability.

Sustainable energy policies guide businesses in adopting cleaner energy sources and reducing their reliance on fossil fuels, such as oil and gas. Examples of sustainable energy sources include solar, wind, and hydroelectric power. Integrating these sources into a facility's energy mix can help reduce greenhouse gas emissions and promote long-term sustainability.

EM systems support energy management programs by providing a platform for monitoring, controlling, and optimizing energy usage across a facility. These systems can help businesses identify opportunities for energy savings, improve equipment performance, and reduce energy costs.
