  • Regional PI Associations (RPA) : Responsible for the regional support of PROFIBUS and PROFINET and localized marketing activities. In India, RPA is named as Indian PROFIBUS, PROFINET Association (RPA). RPA is a marketing organization which has a goal to to promote the PROFIBUS & PROFINET standard in India. During its activities, organize a marketplace for its members. This marketplace is a location where suppliers and purchasing companies can meet each other.

  • PI Competence Centers (PICC): Deliver quality technical support to developers and users of PROFIBUS and PROFINET products and systems. In India, UL Group, Pune and Utthunga Technologies, Bangalore has set up PROFIBUS competence center in India. Also Utthunga Technologies, Bangalore is India’s first and only PROFINET competence center.

From Awareness to Competency:

How to Get Educated on PROFIBUS or PROFINET technologies?


While Industrial Automation may not be the fastest moving industry in the world, something new is still being introduced seemingly daily. Whether that means new hardware, new software, new techniques, or innovative ways to do business, the evolution continues. For example, here in this very publication every month there is a New Products article highlighting new pieces of hardware available. PROFINEWS is an excellent resource to get top-of-mind awareness about the topics important to PI. But awareness is not competency. So for each step of the learning process, PI offers various ways to get educated.

After reading PROFINEWS, what next?



To easily jump into the PROFIBUS or PROFINET technologies, a great place to start is YouTube. 

Videos, as a medium, most efficiently deliver an incredible amount of information in a short amount of time.

Two YouTube channels of note include:

·         youtube.com/user/ProfiTelevision

·         youtube.com/user/MinutePROFINET



Marketing Flyers and White Papers can be downloaded on almost every PI technology and provide a very high-level overview. www.profibus.com/download/brochures-white-paper/



Webinars are a great opportunity to go into depth on a given topic for an extended timeframe at your convenience. Webinars are available on a variety of subjects and the collection of those archived is continually growing. Live webinars are also presented frequently, for example in 2019 on August 21st: PROFINET Introduction for Non-Engineering Roles



Finally, the most important leg in the journey from awareness to competency is training. Learning-by-doing is still the way we truly understand something. Invest a little time and discover the many hands-on training opportunities available from PI. Then, invest and little more time and get yourself trained!


PITC (PI Training Center)

What is a PITC? A PITC is an institute that offers standardized educational sessions aimed at raising the knowledge level of engineers and technicians in several important areas of PROFIBUS and PROFINET. Successful trainees are awarded Certified Engineer or Installer status. PITCs are subject to a Quality-of-Service Agreement administered by PI to ensure the technical excellence of the training they deliver. Each PITC is audited regularly to maintain that high level of quality. The full list of PITCs around the globe can be found here:

Energy management over PROFINET – PROFIenergy

By Siemens Ltd., Mumbai

Energy is one of the biggest operating costs in manufacturing. In order to lower energy costs, increase competitiveness and comply with statutory requirements, end-to-end energy management is essential for industrial production. In this Holistic solution, a key for further reducing energy costs, especially in the field of discrete production, is offered by PROFINET – PROFIenergy

PROFIenergy is an open, standard, ‘profile’ of PROFINET for exchanging data between controllers and high energy automation devices such as robots, drives, conveyors and laser systems in order to facilitate intelligent energy management.  It is based on a set of commands that initiate energy-saving modes in equipment ranging from temporary ‘sleep’ modes to full switch-off.  PROFIenergy also allows for the acquisition of energy consumption data during operation.

PROFIenergy targets pauses (idle times) in production, as these are non-productive periods during which energy is wasted. Idle times depend on many factors including predictable ones such as lunchtimes and weekends and unpredictable ones such as breakdowns or in feed variations. Pauses may also be due to the way an automation system has been configured (e.g. its wait periods). This approach gives complete freedom to the vendor to decide how to optimize Energy and provides flexibility, for example, A production cell requires the conveyor belt to be slowed down before the Robot is put in sleep mode. If the duration of pause is long enough, perhaps the ECU can be completely disconnected but at the same time, when the robot is ready to restart, its conveyor should be restarted in advance. This kind of flexible timing strategy is depicted in diagram

Look for the PROFIenergy logo on the device to ensure the Profinet device also supports PROFIenergy.

PROFIenergy guarantees a uniform interface for energy management. The user is thus free to choose devices from different manufacturers. He can look for the device that is best suited to his application and saves the most energy.

The end user benefits from the competition among device manufacturers and system manufacturers to develop energy-saving solutions as following

PROFINET and OPC UA = Data to Valuable Insight

By Utthunga Technologies, Bangalore

PROFIBUS and PROFINET International (PI) is celebrating its 30th birthday with 1,700 member companies worldwide working together to make the best automation technology for Industrial networking. Worldwide, PROFINET and PROFIBUS node count tops 87 million in the year 2018 and out of which PROFINET continues its accelerated growth and reaches 26 million devices in total and 5.1 million devices being added last year - 2018. 

On the other hand, OPC UA has become the de facto global standard for exchanging the information reliably and securely between the automation systems. There are 47 million automation devices includes OPC technology as per ARC advisory report published in 2018. It is also anticipated that OPC usage will grow at approximately 45% annually for next 5 years. 

Even though PROFINET and OPC UA have some overlap in the automation and process industries, they complement with each other very well in bringing the best vertical and horizontal integration possible as shown below.

PROFINET and OPC UA = Data to valuable insight

In a typical automation topology as shown below, at the field level and up to controller level, PROFINET shall be used for exchange of cyclic and real-time capable I/O data. 


OPC UA can be integrated into the edge device, in this case PN Controller device or PLC. In this scenario I/O data fetched from multiple PN I/O devices are aggregated and analysed, turning the raw I/O data into the meaning valuable insight (information). This enables the vertical integration of the data from the field device into the high level enterprise level application. If both the controller is OPC enabled, then it horizontal communication between the controller is achieved via OPC UA services. 

If the existing PLC does not have support for OPC UA, then external OPC enabled PROFINET edge gateway can be used as an alternative. In this way, data can be fetched and turned into valuable information without disturbing the existing process. This is one of principle behind NAMUR Open Architecture (NOA).


OPC UA can be integrated into the PN I/O device to share the asset and diagnostic information with the higher level system. This will be useful in scenarios like, PROFINET I/O device which does not have connection to the PROFINET Controller system or is not configured to share the relevant asset and diagnostic information or the frequency of the data collected by this I/O device is much higher compared to the PN Controller scan cycle rate. In this scenario, PROFINET I/O device may have local PROFINET OPC UA Information model. Since both PROFINET and OPC UA share the common Ethernet cable, they can share the same infrastructure. However, as there is chance of OPC UA consuming most of the network bandwidth, care should be taken to ensure that this does not affect the performance of PROFINET packets. This can be handled by making network TSN enabled.


§  PROFINET and OPC UA together makes the horizontal and vertical integration efficient, by turning the raw data from field device to valuable information as expected by higher level decision making systems

§  OPC UA can be integrated into PN I/O Device, PN Controller device (PLC) or edge gateway

§  PROFINET and OPC UA in edge gateway enables the Namur Open Architecture (NOA) which highlights upon monitoring and optimizing the process information without disturbing the existing system, instead adding an additional secure OPC UA channel.
