Main Functions

1. Auxiliary high‑speed real‑time algorithm off‑loading: Undertakes partial advanced computing tasks off‑loaded from PPC907BE main processor, reduces main‑CPU computing load for large‑capacity excitation and converter projects.
2. Custom function logic expansion: Supports project‑specific custom algorithm, auxiliary signal pre‑processing and logic processing for UNITROL6000 X‑power excitation system.
3. High‑speed data interaction with host board: Realizes high‑bandwidth real‑time data exchange with PPC907BE main‑processor via mezzanine connector.
4. Local intermediate‑data buffering: Buffers intermediate calculation data, auxiliary disturbance‑recording data.
5. Board‑level self‑monitoring: Detects on‑board power, firmware running status, reports fault status to main processor.
6. On‑board multi‑LED status indication
   • Green LED：On‑board power supply normal, SoC running healthy
   • Yellow LED：Data transmission active between daughter‑board and main‑processor
   • Red LED：On‑board hardware / firmware fault alarm

Installation & Wiring Requirements

1. It is strictly forbidden to hot‑swap. Cut off cabinet total power before disassembly and assembly. Install the daughter‑board onto the corresponding mezzanine connector of PPC907BE main‑processor board, ensure connector fully locked.
2. Ensure cabinet ventilation and heat dissipation; avoid conductive dust and corrosive gas accumulating on PCB surface.
3. Cabinet protective grounding must strictly follow ABB AC800‑PEC / UNITROL6000 system grounding specification.
4. After replacement, verify full‑system firmware matching between daughter‑board and main‑processor board; download matched firmware and project parameters; complete commissioning test.
5. Replacement note：Cannot operate independently, must be paired with PPC907BE series main‑processor hardware and matched firmware version.
