Comparison with Competing Products
• Gongbei Smart-200 Standard PLC – Similar specs, lacks encryption, slightly cheaper but same expandability .
• Siemens S7‑200 SMART SR/ST Series – Genuine OEM with full Siemens support, higher cost ($300–$700), no custom encryption .
• Other third‑party S7‑200 clones (e.g. from AMSA Motion) – Comparable pricing, may lack analog support; encryption appears unique to Gongbei .
