III. Key Upgrade Points (F7102 vs F7101)

Memory ×4: 4MB Flash/4MB SRAM, supports larger program and data volume, complex security logic (such as BMS/F&G).

Dual Ethernet ports: supports network redundancy (such as DCS dual network communication), improves communication reliability.

Enhanced diagnostics: extended communication links / clock synchronization / power redundancy diagnosis, more accurate fault location.

Higher stability: optimized firmware and anti-interference design, suitable for high-load / long-cycle operation scenarios.

IV. Model Interchange and Application

Interchangeability: F7102 and F7101 have fully compatible pins / software, can be directly replaced (ELOP II configuration has no difference).

Typical applications: petrochemical ESD, BMS burner management, F&G fire and gas system, turbine control (TMC) and other medium-large SIS projects.
