  "_comment": "Standard.json — generic Modbus TCP server for the integration suite. Loaded by `pymodbus.simulator`. See ../README.md for the launch command. Holding registers 0..31 are seeded with their address as value (HR[5]=5) for easy mental-map diagnostics. HR[100] auto-increments via pymodbus's built-in `increment` action so subscribe-and-receive integration tests have a register that ticks without a write. HR[200..209] is a scratch range left at 0 for write-roundtrip tests. Coils 0..31 alternate on/off (even=on); coils 100..109 scratch.",
