Introduction

An embedded module is a specialized electronic component designed to perform specific functions within a larger system. Unlike general-purpose computers or devices, which are built to handle a wide range of tasks, embedded modules are focused on executing operations efficiently and reliably. These modules are commonly utilized in various industries and applications, including consumer electronics, industrial automation, automotive systems, medical devices, and more. 

At the heart of an embedded module lies a microcontroller or microprocessor, which serves as the computational engine responsible for executing instructions and processing data. The choice of microcontroller or microprocessor depends on the specific requirements of the application, including factors such as processing power, energy efficiency, and cost. 

Embedded modules for automation are integrated into larger systems to perform specific functions related to control, monitoring and communication tasks in an industrial environment. These modules are usually equipped with robust hardware that can withstand harsh industrial conditions such as extreme temperatures, vibrations and electromagnetic interference. 

Embedded modules can also be tailored to ensure compatibility with widely used fieldbus systems and Real-Time Ethernet standards, ensuring seamless integration and communication within complex industrial networks. The use of embedded modules helps in creating flexible, scalable, and efficient automation systems that can be easily upgraded or modified as technology evolves, and industrial requirements change.  

They also contribute significantly to the advancement and reliability of industrial communication and automation, offering specialized solutions that facilitate interoperability, programmability, and a higher degree of automation within industries. They enable the sophisticated machine-to-machine (M2M) communication required for automated systems to operate with minimal human intervention. Data acquisition, process control, device monitoring, and network communication are some of the tasks handled by embedded modules in the industrial sector. 

Key components of embedded modules for industrial communication

Embedded modules used in industrial automation and communication applications incorporate specific hardware components: 

  • Industrial-Grade Microcontrollers or Processors

    Embedded modules in industrial settings often utilize industrial-grade microcontrollers or processors capable of withstanding harsh environmental conditions and operating reliably in industrial environments. These processors may have extended temperature ranges, enhanced reliability features, and built-in hardware encryption for secure communication. 

  • Memory

    Industrial embedded modules require ample memory to store firmware, program code, configuration data, and temporary variables. These modules typically feature flash memory for storing firmware and program code, as well as static random-access memory (SRAM) or non-volatile memory (NVRAM) for data storage and retention during power cycles. 

  • Industrial I/O Interfaces

    Embedded modules used in industrial automation and communication applications are equipped with specialized industrial I/O interfaces to interface with sensors, actuators, and other industrial equipment. These interfaces may include digital inputs/outputs (DI/DO), analog inputs/outputs (AI/AO), high-speed counters, pulse-width modulation (PWM) outputs, and communication interfaces such as RS-232, RS-485, CAN (Controller Area Network), and Ethernet

  • Real-time Communication Interfaces

    Industrial embedded modules require real-time communication capabilities to exchange data with other industrial devices, controllers, and systems. These modules often support deterministic communication protocols such as PROFINET, EtherCAT, Modbus TCP/IP, and DeviceNet, ensuring timely and reliable data exchange in industrial automation networks. 

Software components for embedded modules in industrial automation and communication applications involves several key considerations: 

  • Real-time Operating Systems (RTOS)

    Many industrial embedded modules utilize real-time operating systems (RTOS) to manage tasks, scheduling, and communication in real-time. The RTOS provides deterministic behavior and prioritization of tasks critical for industrial automation applications. 

  • Industrial Protocol Stacks

    Embedded modules often incorporate industrial protocol stacks to support communication standards commonly used in industrial automation, such as Modbus, PROFIBUS, EtherNet/IP, OPC UA, and CANopen. These protocol stacks enable seamless integration with industrial networks and systems. 

  • Safety and Security Considerations

    Embedded modules in industrial automation must adhere to strict safety and security standards to ensure reliable operation and protect against cyber threats. Software development includes implementing safety-critical features, encryption algorithms, access control mechanisms, and secure communication protocols to mitigate risks. 

Trends and future directions

  • Edge Computing

    Edge computing involves processing data closer to its source rather than relying solely on centralized data centers or cloud services. Embedded modules enable processing data at the edge of networks, reducing latency and enhancing reliability of industrial IoT applications and industry 4.0. 

  • Connectivity Advancements

    As industrial communication technologies continue to evolve, embedded modules will also need to adapt to these developments to enable future connectivity technologies. This includes Single-Pair-Ethernet for example. 

  • Embedded Security

    As embedded modules become more interconnected and pervasive in critical infrastructure and IoT deployments, there will be a greater emphasis on embedded security. Future embedded modules will incorporate advanced security features, including hardware-based encryption, secure boot mechanisms, and intrusion detection/prevention systems, to protect against cyber threats and safeguard sensitive data and operations. Secure-by-design principles will be increasingly adopted to mitigate security risks from the outset of embedded module development.
