In the fast-paced world of industrial automation, split-second decisions can make all the difference. That's where network latency comes in. Network latency measures the time it takes for data to travel across a network from one point to another. While a slight delay might be imperceptible in everyday internet browsing, for industrial applications, even milliseconds of latency can have significant consequences.
Here at Omnitron Systems, we understand the critical role of low-latency networks in industrial settings. In this blog, we'll explore what network latency is, its impact on industrial applications, and strategies for minimizing it.
Imagine sending a control signal from a computer to a robotic arm. Network latency refers to the total time it takes for that signal to travel:
Industrial robots, automated assembly lines, and process control systems rely on real-time communication. High latency can cause delays in receiving sensor data or executing commands, leading to inaccurate movements, malfunctions, and potential safety hazards.
With the rise of Industrial IoT (IIoT), machines and devices communicate vast amounts of data in real-time. Excessive latency can disrupt these data exchanges, hindering efficient collaboration between machines and impacting overall production.
Predictive maintenance and remote monitoring often rely on real-time data collection from industrial equipment. High latency can delay the transmission of critical data, hindering early detection of potential issues and leading to unplanned downtime.
Create separate segments to isolate critical industrial traffic from non-critical network activities. This reduces congestion and prioritizes real-time industrial data.
Invest in a network infrastructure designed for low latency. Fiber optic cabling offers superior speed and reduced signal interference compared to copper cabling. Omnitron provides a range of high-performance industrial Ethernet switches optimized for low latency.
Make use of network optimization strategies such as Quality of Service (QoS) configurations and bandwidth allocation. QoS prioritizes real-time industrial traffic within the network, ensuring it gets transmitted first.
Choose network switches specifically designed for industrial applications. Look for features like low-latency switching hardware which guarantees deterministic data delivery. Omnitron's industrial switches offer these features to minimize latency.
Network latency affects application performance by causing delays in data transmission, leading to slower response times. This can be particularly detrimental to real-time applications where timely data delivery is crucial. In industrial settings, high latency can disrupt automated processes and control systems, reducing operational efficiency. Overall, increased latency can lead to a degraded user experience and potential operational issues.
Network latency can limit throughput by increasing the time it takes for data packets to travel across the network. If latency is excessive, the effective data transfer rate can be decreased even with a high bandwidth. This is because each data packet must wait longer for acknowledgment before the next packet can be sent, creating a bottleneck. Consequently, high latency can prevent the network from reaching its maximum throughput potential.
The industry standard for acceptable network latency varies depending on the application. For general internet use, latency below 100 milliseconds (ms) is typically acceptable, while real-time applications like online gaming and VoIP require latency below 50 ms. In industrial applications, particularly those involving real-time control and automation, latency may need to be as low as 1-10 ms. These standards help ensure smooth and efficient operation across different use cases.
Several factors can affect network latency, including network congestion, where high traffic volumes slow down data transmission. The physical distance between communicating devices also impacts latency, with greater distances causing longer delays. Additionally, the quality and type of transmission media, such as fiber optics versus copper cables, can influence latency. Lastly, the performance of network hardware, including routers and switches, and their processing capabilities can contribute to overall latency.
