Promwad Joined the PROFIBUS & PROFINET International

Banner Profibus Profinet


We became members of PROFIBUS & PROFINET International (PI) to provide our clients with extra value and develop solutions based on the leading standards in industrial automation – PROFIBUS and PROFINET.

Here are some of the benefits of our official membership in PI, the largest international organisation that develops and promotes PROFIBUS, PROFINET, PROFIsafe and PROFIenergy technologies:

  • Accelerated and simplified product development through the free use of patents and technical documentation.
  • Product certification to ensure devices and systems meet communications standards.
  • Technical support and documentation, training and troubleshooting assistance.
  • Access to expertise and networking with other industrial automation companies.


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.



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.



PROFINET is an Ethernet-based industrial communication protocol for real-time data transmission between devices, controllers, and control systems. It is used in Industry 4.0 and the automotive industry.

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

PROFIsafe & PROFIenergy Technologies

PROFIsafe is part of the PROFIBUS and PROFINET protocols and provides them with additional safety.

PROFIenergy is a profile for managing and optimising energy consumption in production and industrial environments, developed as part of the PROFINET and PROFIBUS communication protocols. This profile allows equipment to be put into energy-saving modes when not used.

DC AC servo drives

Case Study: DC/AC Servo Drives

DC/AC servo drives is a project that Promwad engineers implemented by commission from a European manufacturer of industrial automation systems. We were responsible for developing hardware, software and enclosure design to launch servo drives into mass production.

During the development of these devices, we used PROFIBUS and PROFINET protocols, and provided support of advanced protective functions, including the certification for SIL 3 level. As a result, our client received a device with high fault tolerance and performance.


PROFIBUS and PROFINET simplify data exchange in automation and control systems. They enable real-time control, scalability, and integration with IT systems and support efficient production processes. These protocols play a key role in ensuring uninterrupted and reliable data transmission, which makes them indispensable tools for optimising industrial automation.

Promwad's membership in PROFIBUS & PROFINET International gives us access to all necessary documentation and technical support, allowing us to develop industrial automation software and hardware for our clients. Contact us to discuss your project!
