Press Releases

More networking, more safety, more freedom – these somewhat contradictory requirements do not end at the most sensitive part of the machine network: functionally safe communication. This is a task that is best handled jointly.

Previously, functionally safe communication via a fieldbus or Industrial Ethernet was limited to purely Master-Slave or Controller-Device architectures. However, there is currently no cross-manufacturer standard for safe transfers between machines and thus between the controllers used in the machines. Therefore, controllers from different manufacturers cannot currently communicate with each other without additional action being taken. 

PI (PROFIBUS & PROFINET International) and the OPC Foundation have signed a Memorandum of Understanding to start a Joint Working Group to ensure that PROFIsafe will function between controllers from different manufacturers in the future.

IO-Link is the first technology for communicating with sensors and actuators below the fieldbus level to be adopted as an international standard (IEC 61131-9). This technology has now been expanded to include wireless communication.

The IO-Link community has completed work on the specifications for IO-Link Wireless and will publish an approved version at the 2018 Hanover Trade Show. IO-Link Wireless technology will be presented to the broader public in the form of a demonstration at the joint PI booth in Hanover, Germany (Hall 9, D687) for the first time.

IO-Link Wireless defines wireless communication between sensors/actuators and controllers (PLC) in the industrial automation environment. Performance, functionality and capacity are comparable to cable-bound solutions.

IO-Link Wireless offers real-time latency of 5 ms for communication with up to 40 devices (sensors and actuators). Reliability lies above a packet-error rate (PER) of 10-9, while the rates of other comparable wireless standards, such as WLAN, Bluetooth and Zigbee, are around 10-3. IO-Link Wireless supports roaming functions and the option of using battery-operated or energy-harvesting sensors with minimal energy consumption in a real-time network. A key feature of IO-Link Wireless is its compatibility with industry- and process-automation protocols. Planning, commissioning, operation and maintenance can all be carried out using standard IO-Link tools. This guarantees backward compatibility with cable-bound IO-Link systems.

In parallel with the specification work, the necessary test specifications and test scenarios needed when the first suppliers develop their components for the new system are already being defined in the IO-Link wireless working group. The IO-Link community will also be holding an IO-Link Wireless developer workshop at Helmut-Schmidt-Universität (HSU) in Hamburg, Germany in June of 2018. This workshop will enable interested device manufacturers to develop IO-Link Wireless components in a fast and straightforward way.

From Research to the Global Network: The possibilities offered by PROFIBUS and PROFINET in the age of IoT and Industry 4.0

The past three decades have been an exciting time for fieldbus technology. What began as a research project is today the basis for forward-looking Industry 4.0 concepts. And despite the sophisticated technology from PROFIBUS and PROFINET, the future continues to offer a wealth of exciting tasks – such as the integration of TSN.

Today, users can depend on fieldbus devices to reliably communicate with one another, regardless of the manufacturer. This has not always been the case – 30 years ago, the costs of installation, configuration and operationweres enormous. Today’s simplicity for the user is no coincidence. In the first stages of the development of PROFIBUS, two courses were set, which from today’s perspective were almost visionary. The one was the promotion of a development-related standardization process. The other was that the newly-developed fieldbus should be able to be used by all companies. Even with further developments, the user organization – which is now internationally active – has not deviated from these two principles. However, until the point of practical maturity, numerous detail tasks were on the agenda. In addition to the actual technology, a unique quality assurance system – with interface tests, interoperability tests and certification – is also part of the fieldbus world. In order to take into account the application-specific features, the technical committees developed standardized profiles right from the start. This means that the PROFIdrive application profile meets the special requirements of drive technology in combination with the PROFIBUS and PROFINET communication systems. A little later, the PA devices profile for the process industry followed. In 1999, PROFIsafe was presented at the Hannover Messe. The development of PROFIenergy, the vendor-neutral, energy saving profile – which permits the targeted shutdown and restart of components such as lasers, robots or drives during production breaks – also met with great interest a few years ago. In the meantime, the first applications, among others in the automotive industry, are in operation.

Communication of the Future

Very early, PROFIBUS & PROFINET International (PI) relied on Ethernet-based communication. As early as 2001, the first pilot application with PROFINET was introduced. Shortly thereafter, a certification system was established, and the first PROFINET Competence Centers and test laboratories began operations. In 2004, PROFINET achieved a large-scale breakthrough in the automotive industry. Since then, PI has continued to further develop the open Industrial Ethernet standard.Through Fast Forwarding, Dynamic Frame Packing and Fragmentation, cycle times of up to 31.25 μs – along with high-precision isochrone mode – is possible. And even before Industry 4.0 was a mainstream topic in the industrial world, the lifecycle management of plants and machines was high on the priority list for the operators. For this reason, PROFINET has integrated appropriate diagnostics mechanisms to support standardized preventive maintenance. PROFINET stands out with its unique range of functions. The device diagnostics PROFIBUS is known for don’t just enable fast troubleshooting – for example, in the event of a short circuit or cable break. The integrated network diagnostics also ensures short downtimes for many other incidents and helps to optimize the performance of the network.

Seamless integration of new technologies

Increasingly, issues from the IoT and Industry 4.0 worlds are being brought to PI, driven not by the automation industry, but by information technology or basic Ethernet technology. PI sees it as its very own task to integrate new functions and features into proven PI technologies so that they work seamlessly with existing and proven systems. A current example is the integration of TSN: In Industry 4.0 applications, converged networks are real added value. They are characterized by the fact that the IT systems can easily be connected to the OT side. Data from production can be used in software applications without difficulty – for example, for process optimization. It’s also easier to integrate cloud platforms – be it on-site or anywhere in the world. The reporting is simplified with regards to plant or machine performance. Of particular interest is that through the continued evolution of the Ethernet in IEEE 802.1, future devices with standard Ethernet controllers will be developed that will meet all the robustness and deterministic requirements of industrial automation. However, an important finding of the work so far is that the simple configuration of the TSN network parameters will be decisive for user acceptance. For this reason, PI is primarily pursuing the decentralized configuration model of the IEEE – currently being tested in the testbed at Labs Network Industrie 4.0 e.V., for instance – which can be used to create flexible and powerful plant networks.

Simultaneous continuity and progress

Tasks and technologies are constantly changing, but the principles of PI – standardization and openness – will remain as constants. PI is committed to identifying the most important communication requirements for Industry 4.0 and standardizing them as PI technologies are further developed. The key is: users can continue to depend on the fact that the technology they’re already using will last and the transition to new technologies will happen easily.

What you should know about TSN: Karsten Schneider, PI Chairman, gives you the answers!

What can TSN do better than previous Ethernet solutions? 

Karsten Schneider: Ethernet TSN essentially extends the existing mechanisms of Ethernet to include “Quality of Service“ (e.g., bandwidth reservation), synchronization, as well as low latency and even bumpless redundancy. In practice, it looks like this: The applications report their communication needs to the network and get the respective requested QoS guaranteed by the network. The respective connections then run in so-called streams, which then enjoy bandwidth protection via resource allocation in the memory of the switches. In principle, each of these streams can be given a real-time capability. Due to the encapsulated streams, it is also possible with TSN that several real-time capable protocols can be operated in parallel in a single network. This is also known as network convergence.

Is TSN sufficient to transition systems into the age of Industry 4.0?

Karsten Schneider: TSN is just one building block on the way to Industry 4.0-capable systems. PI is currently working on using TSN for PROFINET, but TSN has only layer 2 mechanisms – that is, pure data transport. While this helps break down barriers to communication, IT systems do not understand the meaning of individual data from the machine. So, something must be said about the content. With a suitable semantic description, such as that already stored in the PROFINET application profiles, a quality management system without additional configuration knows that the value received is the torque from a screwdriver control unit. Only then can pure data be used profitably. Apart from that, other topics – such as security, safety or OPC UA – have to be considered for Industry 4.0.

What will happen to the previous PROFINET profiles when using TSN? 

Karsten Schneider: For years, PI has been working on corresponding profile definitions in which information from devices is described and standardized across manufacturers. With TSN, these profiles can continue to be used, along with the complete PROFINET know-how. The vision for PROFINET applications does not change due to TSN. In addition, PI is now incorporating these profiles into the joint working group with the OPC Foundation to create open information models. These can easily be made available to IT systems via OPC UA. Companion specifications for OPC UA arise here with the usage of PI know-how. This will make it even easier to implement Industry 4.0 applications in the future.

Are there already chips for TSN? 

Karsten Schneider: TSN requires a“TSN-capable“ chip. The chips used today cannot usually be upgraded through software on TSN. However, it is foreseeable that, in the future, the standard Ethernet chip will be a TSN-capable chip. Well-known chip manufacturers have already started, or at least announced, the development of chips with TSN mechanisms. Likewise, well-known PROFINET chip manufacturers will develop modules with RT/IRT and TSN, so that the hardware does not have to be changed during the transition to TSN.

What is the timeframe for the developments? 

Karsten Schneider: You should expect it to take up to ten years until a new technology is really assimilated into practice.This is at least the experience we had with the introduction of PROFIBUS and PROFINET. There may be industries where implementation is faster. But one should not forget that it is not only about the creation of the specification – which should be completed in 2019 – but also about topics such as certification, documentation, training and seminars.

These things also require time!

Nuremberg, November 29, 2017: NAMUR, the User Association of Automation Technology in Process Industries, has outlined requirements for the application of Ethernet in the field in its position paper “An Ethernet communication system for the process industry.” These requirements impact the physical layer, among other things. As a solution for this issue, a corresponding physical layer – known as APL (Advanced Physical Layer) – is being created for Ethernet-based communication in the field of process systems, as part of a joint project by well-known industrial companies and organizations, in which PI (PROFIBUS & PROFINET International) is taking a leading role.

This project is based on the new Ethernet standard whose specifications are currently under development by the IEEE 802.3cg working group, for 10Mbit/s via a two-wire system and for up to 1,000 m including optional power supply. The project’s aim is to define the necessary guidelines for the use of the new standard in hazardous areas and to determine the requirements and tools for conformity tests and EMC tests. The solution is also set to be tested within the context of reference designs and pilot implementations.

As part of the further advancement of Industry 4.0 and IIoT, Ethernet (and thus PROFINET) will establish itself in process automation. PROFINET is fast, powerful, flexible, open and offers a host of functions for the specific tasks of the process industry. This includes optimum Redundancy mechanisms, “Configuration in RUN” for smooth device swapping during operation, and Time Stamping for the recording of event sequences, etc. With the market introduction of FDI as an integration technology and the deployment of the PA Profile 4.0, PROFINET has taken two more major steps toward process automation.

The only thing still missing is a solution with which PROFINET Devices can also be provided for use in hazardous areas and in two-wire technology including optional power supply over the data line (similar to PROFIBUS PA). And this is exactly the technological orientation of the APL project.

Eleven prestigious suppliers of systems and devices for process automation – namely, ABB, Endress+Hauser, Krohne, Pepperl+Fuchs, Phoenix Contact, Rockwell Automation, Samson, Siemens, Stahl, VEGA and Yokogawa – are cooperating with PI in this project, as are the organizations FieldComm Group and ODVA.

Nuremberg, November 29, 2017

At the 2017 Hannover Fair, PI (PROFIBUS & PROFINET International) announced their intention to use TSN (Time Sensitive Networking) for PROFINET. The first working group findings are now available and a roadmap for the specification work has been created.

TSN is receiving a lot of attention today, especially in the context of Industry 4.0, and is generally viewed as the opportunity for better integration of OT networks into the IT networks of companies. Through further development of Ethernet in IEEE 802.1, future devices with standard Ethernet controllers can be developed that still meet all the robustness and determinism requirements of industrial automation. Since TSN only defines a Layer 2 for communication, PROFINET is predestined, as an application protocol, to seamlessly integrate TSN, so controllers and field devices can communicate with each other and exchange data.

One focus of the working group that is responsible for the PROFINET standard was defining which of the numerous IEEE 802.1 standards will be required for the specification of TSN integration into PROFINET. Here, synchronization using 802.1 ASrev, TAS (time aware shaper, 802.1Qbv) and preemption (802.1Qbu) are among the most important functions. Through the early selection of supported standards, device manufacturers can prepare for TSN now and plan their next generation of devices with TSN.

However, a significant finding of work so far is that the configuration of TSN network parameters will be among the decisive criteria for success and acceptance by users. TSN will only be easily integrated into systems if it uses a Plug & Work approach that makes extensive adjustment unnecessary. PI therefore primarily pursues the IEEE decentralized configuration model, which allows the creation of flexible, efficient system networks and will be tested, for example, on the test bed of Labs Network Industrie 4.0.

Thanks to the proven basic architecture of PROFINET using standard Ethernet, user perception on issues such as IO data, parametrization, diagnosis, etc. remains unchanged. In view of the large installed base of PROFINET Devices, this is an important compatibility issue for our users.

PI has set the first quarter of 2019 as its goal for publication of the specification for use of TSN with PROFINET.

*** Press Information ***

Nuremberg, November 29, 2017: The PI and OPC Foundation Joint Working Group is making good progress in the preparation of an OPC UA Companion Specification for PROFINET. This team was launched following the discussions and prioritization of issues relevant to PI (PROFIBUS & PROFINET International) in the “Industrie4.0@PI” working group in May 2017. The use cases Asset Management and Diagnosis emerged as especially important.

The collaboration of PROFINET and OPC experts from different firms currently concentrates on the detailed elaboration of concrete use cases, because only a clear, common understanding of users’ requirements leads to an appropriate and subsequently implemented specification.

The PROFINET specification has already performed a lot of preparatory work on Asset Management and Diagnosis use cases, which were also rated as especially relevant by the users. The scope and level of detail of these functions are unique. Thus, the required information is provided to the user in accordance with a standardized structure in the OPC UA object tree following mapping of the objects in the OPC UA Information Model made available via the PROFINET system during vertical access by an IT system via OPC UA client-server calls. This information can then be easily processed in superimposed systems.

Thanks to the TCP/IP channel in PROFINET networks, which has always been open, OPC UA access can take place via the controllers, gateways, or even directly to subordinate devices. Therefore a start in OPC UA can take place flexibly and in phases.

OPC UA is not a new topic for PI. Thus, the FDI specification energetically pursued by PI uses OPC UA services. The already applied OPC UA specification for devices is also used in the PROFINET mapping. The coordination with new activities for mapping of IO-Link in accordance with OPC-UA takes place continuously, ensuring seamless joint integration into the OPC UA Object Model.

The activities aim to create an OPC UA PROFINET Companion Specification by mid-2019. The device manufacturers can continue to integrate the proven PROFINET services without change. A display of information using OPC UA services in accordance with currently defined mapping can then take place in the corresponding devices in accordance with customer requirements.
