If you script too many simultaneous events, the FSP5000RPS’s 64-entry FIFO will overflow, triggering a system reset.
Workaround: Use EVENT_PRIORITY(LEVEL=3) and aggregate status checks into 100ms intervals.
These are not in the public datasheet – derived from reverse engineering the FSP firmware.
| MFR Code (0x9A subcommand) | Function | Allowed Values |
|-----------------------------|----------|----------------|
| 0x01 | Active current sharing mode | 0 = Master, 1 = Slave, 2 = Auto-negotiate |
| 0x02 | PSU health check interval (ms) | 10–1000 |
| 0x05 | EEPROM write protection | 0 = Disable, 1 = Lock all |
| 0x08 | Power-on delay after AC restore | 0–5000 ms |
To write MFR code:
# Example: set unit to Slave mode
dev.write_byte_data(0x9A, 0x01, 0x01)
The software interface described in the manual is utilitarian. It is not designed for aesthetics but for precision. Users can expect:
Secure deployment of FSP5000RPS systems requires attention to:
The manual details a custom scripting language (often Lua-based or proprietary C-variants specific to the OEM) used to define load-shedding priorities.
