Process engineering systems, often based on automation technology from the late 1990s or early 2000s, need an innovation boost to remain competitive. Digitalization offers opportunities for more efficient working, better insight into processes, and additional functionalities. Furthermore, the migration towards Ethernet-based communication promises greater openness and higher transmission speed. Consumers are increasingly thinking online. However, process automation still requires systematic thinking and a pragmatic approach. The NAMUR Open Architecture (NOA) allows for the installation of additional sensor technology and monitoring elements, such as machine learning, artificial intelligence, and cloud services, without disrupting ongoing system operation.

Open Process Automation (OPAF) is based on the idea of a modular IT world with process-oriented systems and long-term availability. Moreover, it has developed into an internationally active consortium of renowned system operators, technology manufacturers, standardization organizations, and software companies, collaborating with NAMUR for pilot projects and industry expertise.

In addition, the Axioline F I/O product family and PLCnext Technology controllers are used in pilot projects. This modular system, originally designed for factory automation, can implement NOA side channels or data diodes. Since 2020, the portfolio has also included intrinsically safe I/O modules for NAMUR sensor technology, HART communication, and valve controllers.

Phoenix Contact has introduced intrinsically safe Axioline F and Axioline P modules in the XC Ex series, which eliminate the need for intrinsically safe power supply modules. The Axioline F system is used in NAMUR automation and PLCnext Technology controllers. The Axioline P module supports Profinet S2 redundancy and is used in zone 2 installations to connect field devices that are mounted in zone 2 or 1. The modules have a black power supply connector and partition plates. A Modbus/TCP version version of the Axioline P family will be launched in 2024, opening up new possibilities in open process applications.

Phoenix Contact offers a range of signal conditioners and measuring transducers for point-to-point wiring in industrial environments. These devices are used to safely isolate, filter, amplify, and convert electrical signals from field devices. The Mini Analog Pro series features intrinsic safety and functional safety, while the revised MACX Analog Ex device family and VIP I/O marshalling provide a comprehensive range of signal conditioners and measuring transducers. In addition, point-to-point wiring offers advantages such as easy installation, high flexibility, easy troubleshooting, and less interference. However, the wiring can be disadvantageous as each device must be connected to the controller. The Termination Carrier from Phoenix Contact eliminates this issue.

Depending on the measuring task, analog sensor signals can be converted into standard signals in an interface block. The conversion result should be proportional to recorded input values, to avoid distortion. Moreover, the standard signal converter adjusts the required signal between the transmitter and the evaluation unit.

An electrically isolated signal connection, referred to as a floating connection, is essential in the plant and process industry. It eliminates compensating currents between potential differences, ensuring the recording of identical signals. This is achieved by integrating a galvanic signal isolator into the connecting cables.

Furthermore, the tasks described are required in various industries, including chemicals, oil and gas, infrastructure, cement, machine building, and renewable energies like wind and solar power.

Fiber-optic cables, often supplied by meters, the different types of fiber-optic cables require different connection technologies for field use. Additionally, they are commonly used for cabling data technology systems, with different fiber types like POF, PCF, and quartz glass. Moreover, suitable tool sets, connectors, distributor boxes, and cables are required for proper cabling and connection, with the fiber type planned for use serves as the starting point.

Polymer-clad fiber (PCF) cables are used in industrial environments due to their robust design and high-quality workmanship. These cables have a 200 µm core and 230 µm cladding, enclosed in a plastic sheath with strain relief elements. 2-core breakout types are commonly used in harsh conditions. Moreover, different connector types are available for field assembly, with tool sets for each type. The cleaver, matched to the respective connector type, ensures a precise and optimally prepared fiber face. Additionally, Phoenix Contact offers PCF cables for various applications.

The Krah Group, a leading global supplier of power resistors for the automotive industry, has introduced a contactless NearFi power and Ethernet transmission solution. The company, based in Germany, has been manufacturing electronic components since 1970. It specializes in developing products with customers and employs around 2,000 people globally at sixteen production sites. The Krah Group is a founding member of the Automotive Center Südwestfalen e.V. association.

NearFi couplers are a new solution for data and power exchange. Offering a flexible and customizable interface. These couplers can be positioned to face each other from any direction and rotate. Reducing the precision needed for mechanical movement. They also display operational readiness with bright LEDs, reducing service calls and maintenance costs. In addition, the contactless solution supports the Profinet Fast Startup function, preventing communication delays. The proximity couplers also offer a simple startup without configuration effort, making them a significant improvement over traditional inductive coupler solutions.
