Hollysys LXS - Data-Transmit/Logic-Run - Compact Reliable Industrial PLC
LXS Series Functional Safety PLC
The Hollysys LXS series is a compact, modular mechanical/functional safety PLC developed on the proven LX architecture, purpose-built for machinery safety loops rather than general-purpose logic alone. Its safety subsystem combines a safety logic control unit with an EtherCAT network unit that communicates safety data via FSoE (Fail-Safe over EtherCAT), enabling scalable distributed safety I/O while keeping the safety architecture clean and auditable.
Key rated attributes include SIL 3 (IEC 61508) / PL e, Cat.4 (ISO 13849) certification by TÜV Rheinland, a system safety-loop response time <20 ms, and mixed installation of safety + standard modules to balance safety and productivity in one cabinet.
Applications & Advantages
LXS is engineered for emergency stop chains, guard/access monitoring, STO/SBC interfacing, press/robot perimeter safety, and other high-integrity machine protection commonly found in semiconductor tools, automotive lines, new energy, logistics automation, and smart equipment manufacturing.
Advantages include the compact footprint, orange-colored safety modules for instant visual segregation, and ready-to-use safety function blocks/safety instruction libraries that shorten validation and help meet compliance evidence requirements.
Core safety functions include safety input/output monitoring, safety communication (FSoE), configurable safety addresses/ranges, diagnostics/status reporting, and cold-reset management, providing deterministic, diagnosable protection.
