* =======================================
|
|
*
|
|
* Register Map:
|
|
* -------------
|
|
* 1. Coils (Read/Write)
|
|
* - Address 0: Relay 1 output (true/false)
|
|
* - Address 1: Relay 2 output (true/false)
|
|
* - Address 2: Relay 3 output (true/false)
|
|
* - Address 3: Relay 4 output (true/false)
|
|
*
|
|
* 2. Input Registers (Read-only)
|
|
* - Address 0-7: Inputs (true/false) - 8 registers
|
|
* - Address 8-9: Temperature (FLOAT32) - 2 registers
|
|
* - Address 10-11: Bus Voltage (FLOAT32) - 2 registers
|
|
* - Address 12-13: Shunt Current (FLOAT32) - 2 registers
|
|
*
|
|
* Note: FLOAT32 values use 2 consecutive registers (32 bits total)
