Single Pair Ethernet (SPE)

From |

A key technology in the digitalization of our world

Digitalization and the Industrial Internet of Things (IIoT) are driving the demand for faster, seamless networking in various industries. Ethernet has proven effective in intelligent device networking, but Single Pair Ethernet (SPE) will replace serial fieldbus communication protocols in the future. SPE’s innovative characteristics make it valuable for advanced communication infrastructures. Phoenix Contact offers cross-industry expertise and an ideal product portfolio for SPE implementation in various fields. Ethernet solutions typically require two wire pairs, but Gigabit Ethernet may require four for increased data transmission rates. Single Pair Ethernet, which works with a single wire pair, can transmit data and power simultaneously. Its transmission rates range from 10 Mbps at 1,000 meters to 1 Gbps at 40 meters, making it suitable for demanding tasks like networked sensor technology. This technology is suitable for fields previously affected by limitations in data rates, ranges, and seamless communication.

Connections of up to 1,000 meters

Standard Ethernet solutions have limitations, such as a maximum of a 100-meter point-to-point connection distance. Furthermore, To cover longer distances in industrial systems, additional repeaters or switches are needed. SPE technology allows devices to be connected over 1,000 meters with 10 Mbps transmission speed and Power over Data Line (PoDL) technology with only one cable, potentially replacing specific fieldbus technologies in the future.

Speeds of up to 1 Gbps and more

Single Pair Ethernet (SPE) is a reliable solution for complex network topologies with gateways, offering transmission speeds ranging from 10 Mbps to 1 Gbps. Hence, IEEE 802.3 consortia is discussing further SPE standards for higher data rates and distances which will open up the spectrum for SPE for even more fields of applications.

Moreover, signal conditioners and measuring transducers are essential for safely isolating, filtering, amplifying, and converting electrical signals.

Signal amplification

Moreover, signal amplification is necessary when a weak signal and can therefore only be acquired in distorted or attenuated form. For example, adding an amplifier reduces the load connected to the measuring sensor to 70 ohms, preventing distortion and ensuring the measurement signal remains accurate.

Conversion to a standard signal

Conversion to a standard signal

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.

Filtering

signal conditioners

Furthermore, interference voltages in cables for measured value transmission can occur due to electromagnetic induction or high-frequency signals. Signal conditioners with filter functions detect and suppress these voltages, while twisted or shielded cables reduce induced voltage. To avoid interference, convert voltage signals into current signals.

Digitalization potential in control cabinet building

From |
 control cabinet building

Control cabinet building can benefit from optimization through digitalization, lean management, and agility approaches. However, manual activities still dominate production, making automation difficult. Electrically skilled personnel are essential for wiring and adaptability, as they understand equipment requirements and can react to unforeseen challenges that cannot be mapped in a highly automated process.

The skills shortage exacerbates the problem

 control cabinet building

Traditional control cabinet building relies on well-trained electrically skilled persons for long-term success, and automation is limited. in addition, time is pressing to integrate the remaining electrically skilled persons into relevant production processes. Moreover, untapped potential in information flows and digital support exists, especially for small and medium-sized companies.

Weaken your weaknesses and strengthen your strengths

 control cabinet building

The saying “Focusing on strengthening your positive qualities and skills while trying to overcome your weaknesses” fits well the digitalizing of company processes. To implement this strategy, identify and categorize areas of the company based on their influence on the company’s success. These areas are typically technical and represent the company’s competitive advantage. The support categories include non-technical areas necessary for core competencies tasks, while organization categories include non-specific areas like HR departments. Introducing market-standard software can help digitalize these areas, addressing weaknesses. However, standard commercial software may leads to loss of unique selling points, impacting the company’s competitive advantage. The digitalization plan should consider practical requirements, employee needs, and company goals.

The role of detailed analysis

 control cabinet building

A thorough analysis of information flow is the first step towards optimizing. Understanding all work steps is essential to identify optimization potential. Digitalized worker assistance systems can help by directly supporting work steps with necessary data. However, ad-hoc integration and digitalization without prior analysis can lead to unnecessary data addition, making the problem worse. However, as humans, we are not good at processing large amounts of data quickly. More data is generally required for automation, but in manual production, it can lead to waste and inefficiency. The challenge lies in sorting and filtering existing data to make it more accessible to employees in a targeted manner.

Data is not always information

 control cabinet building

In digitalization projects involving people, it’s crucial to differentiate between data and information. The term data is used here as a generic term, regardless of its use, and information is the part of the data that is necessary or beneficial for the process. The implementation only considers data classified in the Information field, with redundant data included if necessary. Uniform implementation in the form of just a document, as is the case in production supported by paper documentation, is therefore not the optimal solution, as it can lead to the optimization of specialist processes. Paperless production is a welcome side effect of digitally supported optimization.
