## AIO-422-R1 — ESPHome Modbus package (v0.2.0)
##
## Single package file — include from your ESPHome YAML:
##   packages:
##     aio: github://isystemsautomation/homemaster-dev/AIO-422-R1/Firmware/v0.2.0/default_aio_422_r1_plc/default_aio_422_r1_plc.yaml
##
## Requires global `modbus:` with id `modbus_bus`. If UART/Modbus are not defined yet, uncomment:
# uart:
#   id: rs485_uart
#   tx_pin: GPIO4
#   rx_pin: GPIO5
#   baud_rate: 19200
#   parity: NONE
#   stop_bits: 1
# modbus:
#   id: modbus_bus
#   uart_id: rs485_uart
##
## Input Registers (FC=04, read) — contiguous 0..11 (one merged poll per cycle):
##   0 BTN_MASK (bit0..3 = buttons 1..4)
##   1 LED_MASK (bit0..3 = LEDs 1..4, physical)
##   2 STATUS_FLAGS (bit1=linkOk, bit3=cfgDirty)
##   3 FAULT_MASK (bit0=RTD1 sensor fault, bit1=RTD2 sensor fault,
##                 bit2=!ads_ok, bit3=!dac_ok[0], bit4=!dac_ok[1],
##                 bit5=!rtd_ok[0], bit6=!rtd_ok[1])
##   4..5  RTD1/RTD2 temperature  S_WORD °C×10
##   6..9  AI1..AI4               U_WORD mV
##   10..11 AO1/AO2 raw state     U_WORD 0..4095 (state, not command)
##
## Holding (FC=03/06) — AO command at 200/201 write-only via output platform.
##   Legacy HREG 120..121 / 140..143 remain on the module for non-package clients;
##   this package does not poll them (STD-009).
##
## Identity (IREG 200..204) is not polled — configuration, not loop state.
