BL234 EdgePLC IEC 61131-1 Automation Industrial Edge Controller
Short Description
The BL234 EdgePLC series is an industrial edge controller designed for the convergence of real-time control and edge computing. As industrial automation evolves toward “Control + Edge Intelligence,” traditional PLCs often lack computing capability, while industrial PCs struggle with deterministic real-time control.
