Why is the possibility of working with these technologies – PROFIBUS, PROFINET, PROFIsafe, PROFIenergy – so crucial for our clients who use our engineering services to create solutions for industrial networks, servo and stepper motor drives, PLC, DAQ, and sensors? Let's take a closer look at them.

 

Why do you need PROFINET?

PROFINET embedded services provide a reliable solution for real-time data exchange between different automation devices. PROFINET, an Ethernet-based protocol, enables smooth integration of devices from different manufacturers, ensuring compatibility and reliability in complex automation environments. This technology is particularly valuable in industries that require high-speed data exchange and deterministic communication, such as manufacturing, automotive and process control.

In the context of PROFINET embedded design, we focus on integrating PROFINET capabilities directly into embedded systems such as PLCs (programmable logic controllers), sensors, actuators and other industrial equipment. Promwad also provides custom embedded software development, network performance optimisation and PROFINET compliance services for real-time operations and latency reduction in mission-critical processes.

As part of this service, we configure and test embedded devices in a PROFINET environment. It includes configuring communication parameters and addressing and diagnostic tools that help monitor and maintain network health. The ability to perform real-time diagnostics and rapid troubleshooting minimises downtime and ensures continuous operation in industrial environments.

For enterprises, using PROFINET embedded services means better flexibility of automation systems. As production requirements change, companies can easily modify their operations by integrating new devices into the PROFINET network without huge reconfiguration. Integration PROFINET into embedded devices provides real-time communication, improved diagnostics and the flexibility to scale operations, making it a cornerstone of industrial automation strategies.

PROFIBUS Protocol

PROFIBUS is a network protocol that provides data exchange at the field level (between controller and sensors) and higher-level communication systems. We use two variants of this protocol for different industrial applications:

 

  • PROFIBUS DP (Distributed Periphery) is a protocol for data exchange with peripheral devices. It is used where high data transfer rates are required.
  • PROFIBUS PA (Process Automation) is a protocol connecting field devices and control systems. It is used in hazardous areas.

 

PROFIBUS can be implemented for distributed I/O applications, providing high performance and efficiency.

One PROFIBUS DP cable can connect up to 126 input/output devices, each connecting to tens and hundreds of connection points. It allows for optimal and efficient operation of a single controller.

With this standard, we realise proactive equipment management when new devices are introduced without stopping work. It is made possible by PROFIBUS Profile v 3.02, which allows new devices to adopt the functionality of previous versions temporarily.

The protocol can be used in various industries for reliable and efficient data exchange between devices and control systems. The main areas of application include industrial and process automation, energy management, building automation, transport and logistics, the food and beverage industry, and the automotive field.

PROFIBUS Software Design

PROFIBUS software design is an important aspect of industrial automation that involves developing software solutions for communication and control systems using the PROFIBUS protocol. 

As, among other things, a PROFIBUS software company, Promwad specialise in efficient software development for better data exchange between various industrial devices, such as sensors, actuators, and controllers. PROFIBUS is known for its reliability and real-time capabilities, which makes it a perfect choice for manufacturing, process automation, and material handling.

Supporting different network architectures – linear, ring or star – PROFINET can be easily adapted to specific enterprises' conditions and saves on standard solutions.

PROFINET Embedded Development

PROFINET embedded development is an area of industrial automation that integrates PROFINET capabilities into embedded systems such as sensors, actuators and controllers. It involves creating customised firmware and software that allows these devices to communicate effectively over PROFINET. By embedding PROFINET into devices, companies ensure deterministic communication for robotics applications, factory automation and process control.

In addition to software integration, developing PROFINET embedded systems often involves designing hardware components that support the PROFINET protocol. It includes selecting suitable microcontrollers, developing custom PCB, schematics, and ensuring that the hardware meets the stringent requirements of industrial environments, such as electromagnetic compatibility (EMC) and temperature tolerance.

IO-Link communication is a standardised IO technology that facilitates seamless communication between sensors, actuators, and the automation system. This protocol is designed to support different applications, from simple binary sensors to more complex devices that need extensive data exchange. 

The IO-Link communication protocol allows for bidirectional data exchange, making configuring, diagnosing, and maintaining connected devices easier. It is an effective tool in industrial automation due to its capability to deliver complete device diagnostics and parameter data.

When integrating IO-Link with PROFINET, the IO-Link Master PROFINET module has an important function. This master module is the gateway, translating IO-Link data into a format the PROFINET network can understand. The PROFINET IO-Link Master provides communication between the field devices and the controller, resulting in accurate and real-time transfer of data.

Beyond PROFINET, IO-Link also extends its compatibility to other industrial Ethernet protocols, such as EtherNet/IP and EtherCAT. The Ethernet IP IO-Link Master and EtherCAT IO-Link Master allow IO-Link devices to be connected to EtherNet/IP and EtherCAT networks, respectively. This flexibility ensures that IO-Link can be used in various industrial settings, regardless of the preferred network protocol. It makes IO-Link an ideal solution for manufacturers who require versatile and scalable automation systems.

The adaptability of IO-Link to Ethernet IP is particularly noteworthy, as it enables the connection of IO-Link devices to Ethernet-based systems without losing any of the benefits of IO-Link communication. Users can keep a reliable connection across the various layers of the automation system – from the factory floor sensors and actuators to the higher-level control systems – by converting IO-Link data to Ethernet IP.

Overall, IO-Link communication enhances the efficiency of industrial automation by providing a standardised, flexible, and easy-to-integrate solution for connecting devices across different networks. Whether it's PROFINET, EtherNet/IP, or EtherCAT, IO-Link ensures that data is communicated effectively, enabling advanced diagnostics, simplified configuration, and improved overall system performance.
