Edge computing is closely tied to cloud computing, with the latter gaining importance in Industry 4.0 projects. Though relatively new, edge computing’s potential is exemplified by the EPC 1502 edge device.
A user needs an Internet connection to link systems to a cloud for data evaluation and storage. However, for applications requiring quick data processing, public cloud solutions are unsuitable due to Internet latency. Users are increasingly using Edge computing for these smart applications. Phoenix Contact’s edge devices, based on the PLCnext Technology ecosystem, combine robust industrial PCs with an open automation platform. This approach enables intelligent IoT edge concepts and optimizes the entire value chain by processing and analyzing large data volumes locally.
Easy to integrate box for collecting local data
Edge devices have broad applications, where data needs to be analyzed or is already being analyzed in the cloud. When developing edge applications, users often ask how to centrally accumulate data. Creating autonomous vehicles, traffic light systems, or intelligent thermostats that benefit from edge computing can be complex. The edge device must be flexible and able to collect large amounts of data from various sensors and manufacturers. Additionally, field devices use different industry protocols, and much of the data is analog, making accumulation challenging.
The tailor-made Edge Collection Box from Phoenix Contact is ideal for collecting local data. It gathers digital, analog, and temperature signals via connected sensors and integrates easily into existing production environments. Furthermore, Data collection takes place in parallel, preserving the CE marking of machines. The main component, the EPC 1502 PLCnext Control with an IIoT framework, facilitates easy collection of energy and process data using industry-standard communication protocols.
Secure Data Box as a secure interface to higher-level IT systems
Once data is collected and analyzed locally via the edge device, it often serves as an intermediate layer to the cloud. Transferring summarized data, evaluated alarms, and analyses securely to the cloud can be challenging. Moreover, Phoenix Contact’s Secure Data Box, used with the Data Collection Box, provides a secure interface between the production network and higher-level IT networks, external service providers, and cloud systems. The integrated FL mGuard security router’s firewall blocks unauthorized access, allowing only necessary data traffic. Via the mGuard Secure Cloud app, one can access the EPC 1502 edge device for remote maintenance information.
Reliable operation of automated guided vehicle systems
Additionally, using an edge device in an automated guided vehicle system (AGVS) bridges the gap between classic control functions and AGVS navigation. It offers a plug-and-play interface for the Robot Operating System (ROS) and supports high-level language programming, the ROS interface, and Docker software, allowing users to implement their own approaches. The PLCnext Technology online store provides apps for sending firmware and application updates to all controllers.
Furthermore, the edge device provides a secure entry point for remote maintenance and displays collected data via dashboards. AI algorithms analyze data to detect anomalies, enabling predictive maintenance and minimizing downtime. With atypical interfaces, data can be forwarded via WLAN, saving on cables. The large internal storage allows for long-term local data storage. Edge devices are essential for the reliable operation, efficiency, and flexibility of automated guided vehicle systems.
Wide range of possible uses in large and small applications
There are various applications for Edge computing. Ready-to-install edge boxes simplify implementing large systems that collect data using different protocols. Moreover, existing systems can be easily converted to edge computing with integration-capable solutions installed outside machines, retaining their CE marking. In smaller systems, edge devices must support many protocols and apps to provide added value with simple installation.
Before making an electrical connection, conductors need to be stripped a process that varies depending on the type and characteristics of the conductor. Stripping conductors is challenging due to the variety of types and their unique characteristics, with high demands on reliability and efficiency. Stripping involves removing the insulation to a certain length, as determined by the geometry of the terminal or connector. In addition, it can include removing the outer sheath of multi-core cables. Ensuring a safe electrical connection means avoiding damage to the litz wires, single-core wires, or braided shields. The process must conform to DIN IEC 60352-2 standards, which specify the requirements for a perfect stripping result. Depending on which tool is used, clamping the conductor can lead to pressure points and thus to discoloration of the insulation.
To avoid damage to litz wires, the stripping process involves two steps: “cutting into” and “pulling off” the insulation. First, the insulation is cut to a clearance of about 0.1 mm to 0.3 mm from the wires. Then, the uncut area of the insulation is pulled off to complete the removal.
Non-adjustable hand tools
Stripping can be performed using hand or automatic tools. Hand tools are categorized into non-adjustable, adjustable, and automatically adjustable types. Non-adjustable tools, like the Wirefox-MP VDE multifunctional tool, are the simplest and can handle a wide range of conductor sizes (0.2 to 10 mm²), allowing quick processing of different conductors. However, these tools require practice for perfect results and are not suitable when high level of process reliability is needed due to their lack of adjustability.
Adjustable hand tools
Adjustable tools enhance process reliability and require minimal practice. Tools with a rotating blade, like the Wirefox-D 40, are suitable for sheath removal and stripping in cross-sections over 10 mm², ensuring a uniform incision depth. For smaller cross-sections, non-rotating cutting edges are used, increasing the pull-off proportion.
While tools like the Wirefox-D 40 have broad applications, specific tools like the Wirefox D-CX series are designed for multi-stage stripping of coaxial cables. These tools are selected based on the connector type to achieve the required stripping lengths. However, they are not ideal for frequent material changes due to the time needed to set them up.
Automatically adjustable hand tools
Automatically adjustable hand tools offer the combined benefits of non-adjustable and adjustable tools, providing fast material changes and high process reliability. They use different blade geometries for various applications: flat blades for PVC cables up to 10 mm², half-round blades for cross-sections up to 16 mm² to minimize force required, and V-blades for hard insulation materials like PTFE and soft rubber. Stripping lengths can be set with an adjustable stop, and blades can be easily replaced without tools, ensuring long service life.
Automatically adjustable hand tools are also available for special applications, such as stripping SAC cables, AS-Interface flat cables, and flat-ribbon cables. These tools are recommended wherever applicable due to their versatility and efficiency.
Manually adjustable automatic tools
In series production, where quantities and quality demands are high, hand tools are reaching their limits. No matter how ergonomic the hand tools are, fatigue is inevitable. This is where automatic tools, like the entry-level electric WF 1000 stripping device, become essential. Once parameters such as cross-section, stripping length, and pull-off length are set, this device can quickly process many conductors without causing fatigue. However, each material change still requires some time to adjust the stripping parameters. This machine is especially suitable for processing identical materials efficiently.
Automatically adjustable automatic tools
The new E.Fox S 10 automatic stripping device is optimal for production processes that require frequent material or parameter changes. Its electrical adjustment of stripping parameters allows for swift material changes. The device is user-friendly, featuring an intuitive touch display interface. Users can save and recall favorite stripping parameters using a barcode scanner, significantly boosting efficiency.
The E.Fox S 10 automatic stripping device reduces the potential for human error compared to manual settings. It can function as a stand-alone device or be integrated with the Clipx Wire assist worker assistance software via an Ethernet interface. This allows for consistent use of production data and reliable processing of large, multi-version orders. When combined with other automatic tools and printing systems controlled by the same software, an efficient and customized worker assistance system for wire preparation can be created.

To optimize jumping performance, ccc software gmbh and the Institute for Applied Training Sciences have developed a sophisticated solution for training optimization and competition management. The camera must be mounted parallel to the jumper and at flight-path height. However, the jumper is only parallel with the camera for a fraction of a second. The IAT, founded in 1992, supports around 1,000 athletes and their coaches from 19 summer and six winter sports. Aiming to identify and tap into Germany’s top athletes’ performance potential.
Floating connectors with considerable tolerance compensation and high-speed data transmission
When it comes to board-to-board connectors, there are numerous versions: small and large pitches, low and tall designs, robust and simple connectors. The Finepitch FS 0,635 series connectors with floating properties are a new addition to the Phoenix Contact portfolio. What makes floating board-to-board connectors so special? Where are they used? And are high-speed data transmission and floating a contradiction in terms?
Features of a floating connector
Board-to-board connectors consist of the contacts that establish an electrical connection and a housing that protects and fixes the contacts. While floating connectors have two housing parts connected by contact metals. The inner housing contains the pin connector pattern, while the outer housing protects soldering surfaces and contacts. The floating contacts are long and curved, allowing the inner housing part to move within the limits set by the outer housing. This allows the pin connector pattern to be moved within a large tolerance range while the soldering area remains fixed. The FS 0,635 series allows a tolerance of 0.6 mm in the plug-in direction, known as wiping. The FS 0,635 floating female connector strip can be combined with three male connector strips to create different stack heights.
Climate change and population growth are posing a global challenge. How to stop global warming and increase energy consumption while protecting the climate? The All Electric Society vision aims for a sustainable, affordable energy system where renewable sources, such as sun, wind, and water, are used. Researchers at Oregon State University predict that photovoltaics could cover all energy requirements globally, using less than 1% of the earth’s surface. However, achieving this energy revolution requires extensive renewable energy expansion of renewable energy and the technological approach of sector coupling.
Sector coupling
Sector coupling involves the comprehensive electrification, networking, and automation of all relevant areas of our lives and economies. Including industry, energy, mobility, infrastructure, and buildings. In the All Electric Society, these sectors are networked to create a self-controlling system that optimizes energy efficiency and energy savings by balancing loads, producers, and storage systems. This ensures stability and availability of power supply without excess capacity. Making energy storage systems a core element of sector coupling.
The role of energy storage systems in an All Electric Society
To ensure a stable power supply based on renewable sources like sun, wind, and water, reliable storage systems are necessary. There are various technologies for temporarily storing electrical energy, with the main difference being their physical principles. Mechanical storage converts electrical energy into mechanical energy. While purely electrical storage uses capacitors or inductors. Electrochemical storage uses electrochemical potentials and electrolytes to store electrical energy in batteries. Thermal storage generates heat and drives electrical generators.
Simple implementation with the PSRmodular and AXL F series
Phoenix Contact offers two series of analog signals for monitoring physical variables in process engineering systems. These signals are standardized as either a (0)/4 … 20 mA or a 0 … 10 V signal, with current signals being more robust against electromagnetic interference and having high measuring accuracy over longer cable lengths. Furthermore, the concept considers whether the sensor is powered by the evaluation module or supplied by an external source.
Consideration of load and measurement information
The analog evaluation module distinguishes between active and passive inputs, requiring external supply for passive inputs. Load consideration is crucial when engineering analog signals, and signal conditioners are recommended if it exceeds active inputs. Moreover, NAMUR recommendation NE43 defines signal levels for failure information of digital measuring transducers with analog output signals, with current values outside these limits considered invalid or failure information. The evaluation unit must provide corresponding information or respond to deviations.
Design of functional safety
Single-channel analog signal generators can be used for safety-related circuits up to SIL 2/PL d. While two-channel signal generators can be used up to SIL 3/PL e. MTTFD values can be determined based on sensor manufacturer failure rates. Furthermore, Diagnostic coverage (DC) is required for safety-related analog signals, but plausibility comparison is difficult due to measurement inaccuracies and ambient conditions. Two-channel architectures should allow short-term deviations outside the tolerance range, without impacting functional safety.
DC technology: Test facility shows potential savings
DC grids in the automotive industry are a key step towards climate neutrality. A production plant in Dingolfing, Bavaria, uses Phoenix Contact components to supply a unique DC grid system for robotic arms and automotive parts.
It was AC power supply in the beginning
In the late 19th century, Thomas Edison (DC) and George Westinghouse (AC) fought over large-scale power grid supply. Ultimately, choosing alternating voltage is due to AC voltage’s ability to be transformed up and down.
The advantages of direct current
DC technology offers efficient direct current usable at a low cost. Making it suitable for electronic devices, electric cars, and renewable energy. Furthermore, DC grids can eliminate lossy AC/DC conversion and integrate renewable energy systems efficiently. Moreover, Phoenix Contact provides solutions for intelligent control of power flow and networking, ensuring high availability and supply security.
