 "summary": "ComAp's InteliGen4 200 is a gen-set controller for multiple-set (MINT) and single parallel-to-mains (SPtM) applications. Its Modbus RTU and Modbus TCP map is generated per configuration, so values and setpoints must be exported from InteliConfig for each controller. This page covers only the registers ComAp fixes in every controller: the command interface used to start/stop the engine, reset faults and operate breakers, the password and error registers, the alarm list count, and the remote-control data registers.",

  "A successful command returns a fixed value in 4207-4208 (e.g. 0x000001FF after engine start); 0x00000001 means invalid argument and 0x00000002 means refused (wrong mode, breaker cannot be closed now, etc.).",
  "User buttons 1-16: code 0x47 (buttons 1-8) or 0x48 (buttons 9-16) with argument 0x00nn0000, where nn = 10 x button number for PULSE, +1 for TOGGLE, +2 for ON, +3 for OFF (e.g. button 1 PULSE = 0x000A0000, button 16 OFF = 0x00A30000; table on p. 206).

  "Left out: RTC time and date (4200-4203, BCD-coded pairs), the 16 alarm-list records at 4215-4646 (27-register structures holding level, status and a UTF-8 text), and RemoteControlBin_1..16 at 5210-5225 (no data type given).",
  "The reserved-register table prints '4010' for the 'Not implemented' row between 4209 and 4211; from its position this is 4210.",
