Next-Gen WebAssembly HMI: Native Performance for SCADA

Key Takeaways: WebAssembly bypasses standard JavaScript interpreters, delivering highly deterministic execution for compute-intensive industrial interfaces. Hybrid approaches are dominating: standard web technologies handle the DOM layout while WebAssembly processes real-time math and heavy signal rendering. Portability allows automation engineers to write core logic in memory-safe languages and deploy identical binaries to edge gateways and control […]

Heat Exchanger Sizing with the LMTD Method

Every process engineer who has ever specified a shell-and-tube or plate exchanger knows this moment: the process simulator spits out a heat duty, and the next step is converting that number into square meters of transfer surface. The bridge between thermal duty and physical hardware is the Log Mean Temperature Difference (LMTD) method. This article […]

Integrating WebRTC for Real-Time Video Streaming in SCADA HMI

Key Takeaways: Standard streaming protocols (HLS, DASH) induce multi-second delays, unacceptable for critical remote operations. WebRTC integration in SCADA HMI provides ultra-low latency (< 500ms), enabling real-time tele-operation and monitoring directly in modern browsers. Implementing WebRTC on the plant floor requires bridging legacy RTSP feeds and managing NAT traversal via STUN/TURN servers. Using a Selective […]

Inside Three-Phase Transformer Sizing Calculation

Key Takeaways: Industry standard practice recommends sizing a transformer at roughly 120% of the calculated maximum load to prevent thermal degradation. Short-circuit current calculation is heavily dependent on the percent impedance (%Z) found on the transformer nameplate. Ignoring downstream impedance when sizing secondary circuit breakers provides a conservative, “infinite bus” safety margin. Properly sizing an […]

Inside Single Pair Ethernet (SPE): Architecting 10BASE-T1L for PLC Networks

Replacing legacy 4-20mA systems with IP-based networks has always been a challenge in the process industries due to distance limits. Single Pair Ethernet (SPE), specifically the IEEE 802.3cg 10BASE-T1L standard, fundamentally changes this by delivering power and 10 Mbps Ethernet over a single twisted pair up to 1,000 meters. This shifts the automation paradigm from […]
