To meet the hard real-time requirements of modern motion control systems, MLE Robo/TSN uses hardware acceleration to implement secure “tunnels” which transport existing OT fieldbus protocols over standard IEEE TSN Ethernet.
Hence, you can add new connections without adding new wires!
MLE Robo/TSN is fully transparent to the PLC software and backwards compatible which demonstrated in SPS Magazin 9 2025 (P.31) as an enabler for virtualizing PLCs in a Factory Cloud.
Such virtualization gives better scalability and flexibility while allowing central maintenance and configuration. This improves Overall Equipment Effectiveness (OEE) and Development Time.
Unlike many legacy fieldbus protocols MLE Robo/TSN can use Post Quantum Cryptography (PQC) to secure data transfers and to protect against man-in-the middle attacks, for example.
