Schneider Conext AGS generator start module

Round-trips through a real Modbus stack with no overlapping addresses and a word-order-sensitive codec — the map is internally coherent and wire-decodable. Does NOT prove byte-order or scaling match a real device: the emulator is seeded from the map's own types, so a uniformly wrong byte-order still round-trips. Only hardware-verified confirms byte-order/scale on the wire.

link settings as documented (unverified): Modbus does not provide an error response when data written to a Modbus Register is out of range or invalid. To confirm that a Modbus Register is correctly written, you should read it back and compare it with the expected value.

⚠ UNINTENDED OPERATION: The use of this product with Modbus communications requires expertise in the design, operation, and programming of the device. LOSS OF CONTROL: Do not assign the same address to two Modbus devices. — Starkest reads only; we never write a control register.

⚠ disputed: configuration_status @ 53 — disputed by Home Assistant Modbus YAML mapping (derived from Schneider spec 990-6274A) which places configuration_status at 0x0035 (53 decimal), but configuration_refresh_counter is at 0x0036 (54 decimal), device_state is at 0x0040 (64 decimal), device_present is at 0x0041 (65 decimal), auto_generator_state is at 0x0042 (66 decimal), auto_generator_action is at 0x0043 (67 decimal), generator_on_reason is at 0x0044 (68 decimal), generator_off_reason is at 0x0045 (69 decimal), active_faults_flag is at 0x0046 (70 decimal), active_warnings_flag is at 0x0047 (71 decimal), fault_bitmap_0 is at 0x0048 (72 decimal), warning_bitmap_0 is at 0x0049 (73 decimal), configuration_errors is at 0x004A (74 decimal), operating_mode is at 0x004C (76 decimal), generator_mode is at 0x004D (77 decimal), generator_quiet_time_start is at 0x0050 (80 decimal), generator_quiet_time_stop is at 0x0051 (81 decimal), generator_quiet_time_enable_disable is at 0x0052 (82 decimal), generator_auto_start_on_dc_v is at 0x0053 (83 decimal), generator_auto_stop_on_dc_v is at 0x0054 (84 decimal), generator_auto_start_on_battery_soc is at 0x0055 (85 decimal), generator_auto_stop_on_battery_soc is at 0x0056 (86 decimal), inverter_load_start_stop_triggers is at 0x0057 (87 decimal), generator_auto_stop_on_ac_i is at 0x0058 (88 decimal), generator_stop_at_absorption_stage is at 0x0059 (89 decimal), generator_stop_at_float_stage is at 0x005A (90 decimal), maximum_automatic_cycles_with_no_user_intervention is at 0x005B (91 decimal), thermostat_1 is at 0x005F (95 decimal), thermostat_2 is at 0x0060 (96 decimal), generator_type is at 0x0061 (97 decimal), generator_preheat_time is at 0x0063 (99 decimal), generator_crank_start_delay is at 0x0064 (100 decimal), generator_crank_time is at 0x0065 (101 decimal), shutdown_bypass_time is at 0x0066 (102 decimal), starter_cool_down_time is at 0x0067 (103 decimal), generator_crank_retry_time is at 0x0068 (104 decimal), generator_warmup_time is at 0x0069 (105 decimal), maximum_generator_run_time is at 0x006A (106 decimal), generator_cool_down_time is at 0x006B (107 decimal), generator_spin_down_time is at 0x006C (108 decimal). Note that the provided register map summary lists decimal addresses that match these hex values exactly (e.g., 0x0035 = 53, 0x0040 = 64, 0x0050 = 80, 0x0061 = 97), confirming the 0-based decimal addresses are correct.
