Using existing infrastructures for SPE

From |
SPE

Phoenix Contact tested various cable types in building automation to determine if existing cables can be reused for Single Pair Ethernet (SPE). The investigation compared the technically relevant sizes of the cables with the limit values of ISO/IEC 11801-3, IEEE 802.3cg, and IEEE 802.3da. In addition, the quality of signal transmission over different cable lengths was examined using parameters to assess signal integrity.

Determination of the cable types

Determination of the cable types

The KNX protocol is widely used in building automation in Europe, particularly in Germany. J Y(ST)Y 2x2x0.8 type cables are used for bus signals, power installations, and process data processing. The YV 2×0.8/1.4 jumper wire, also known as a bell wire, is used for point-to-point connections. These cables were examined for their reuse in SPE connections.

Selection of suitable measured variables and measurement methods

Selection of suitable measured variables and measurement methods

The Fluke DSX 8000 field tester was used for cabling measurements, qualifying Ethernet cabling, and testing patch cables. In contrast, comparative measurements were conducted using the ZNBT vector network analyzer. Cables with good transmission properties meet limit values for RL, IL, and TCL and require constant independence of the cable. Phoenix Contact SPE connector was used for easy connection.

Investigation of realistic cabling structures

Investigation of realistic cabling structures

Moreover, existing bus line infrastructures can have unknown topologies, making it difficult to dismantle the installed cables. The transmission path has branch lines of varying lengths. A T-shaped line arrangement with master cables and branch lines was examined. The results showed that short cable lengths and non-terminated cable ends were problematic. Long cables were found suitable for SPE transmission.

Signal-based investigations

The KNX bus line and jumper wire’s Signal-to-Noise Ratio (SNR) and Slicer Maximum Absolute Error were measured using two evaluation boards. The KNX bus line achieved a maximum range of 420 m with a minimum SNR of 30.1 dB and a Slicer Maximum Absolute Error of 0.15, while the jumper wire reached a maximum range of 910 m.

Push-X: Tool-free connection increases efficiency

Push-X technology

New connection – yet proven a billion times over

Phoenix Contact has introduced the Push-X technology, a tool-free connection method that enables flexible conductor connections without pretreatment. This innovative technology uses the Push-in connection from Phoenix Contact, which has been used for years and is primarily found in the terminal block sector. Additionally, the new technology uses a trigger inside the terminal block, triggers a pre-tensioned spring, and has been redesigned for vertical connection.

One connection compatible with all conductors

The Push-X system is suitable for all types of conductors, including rigid and flexible ones. It uses a pretensioned spring on delivery, releasing the locking mechanism with light pressure. Eeven the smallest flexible conductors can be connected without tools. The orange actuating push button signals the connection and audible feedback. The system is easy to release and reuse, with any tool being used to return the button to its original position.

Push-X technology

New to the market, but already a whole family

The Push-X family has also introduced new XTV terminal blocks, available in nominal cross-sections of 6 mm², 10 mm², and 16 mm². These terminal blocks are part of the Clipline Complete system, offering advantages such as vertical connection, lateral entry, and easy-to-read terminal point marking. Furthermore, the XTV technology is compatible with other systems and can be combined with other accessories. So, switching to using terminal blocks with Push-X technology will not be a problem. The terminal blocks are similar to spring-cage and Push-in terminal blocks.

Save a lot of time with Push-X technology

The All Electric Society is transforming infrastructure for renewable energy distribution and storage, increasing demand for switchgear and controlgear systems. To improve efficiency, tool-free connection technologies like Push-in and Push-X are being used. Push-X eliminates the need to change tools and requires no further checks, making it quick and easy to switch.

Cost and time savings with increased safety and better quality

The digital twin, often associated with the Asset Administration Shell (AAS) in the German “Plattform Industrie 4.0” initiative, is a crucial tool in the manufacturing sector for securing automation applications. It provides a digital image of a complete automation application, enabling users to simulate individual components’ behavior and provide a comprehensive view of the entire production process.

Virtual commissioning with the RF::Suite and PLCnext Technology

Decisive use case of the industrial digital twin

The digital twin is a digital representation of manufacturing system components, used to simulate and analyze production systems. It helps identify potential fault scenarios and simulates system behavior under different conditions. Virtual commissioning is a crucial use case for industrial digital twins, especially in complex production systems. It allows for cost-effective testing of virtual models before completion, enables safe testing without endangering people, machines, or the environment, and helps detect faults early, improving end-product quality and shortening startup time.
