The code must be properly commented and contain the identifiers to be entered.
The modbus 1 (0x01) function is to read the values from several flag registers (Read Coil Status). 2 (0x02) - Reading values from multiple discrete entries (Read Discrete Inputs). 3 (0x03) - Reading values from multiple storage registers (Read Holding Registers). 4 (0x04) - Reading values from multiple input registers (Read Input Registers). 5 (0x05) - a record of the value of one flag (Force Single Coil). 6 (0x06) - a record of the value in one storage register (Preset Single Register). 15 (0x0F) - recording values in multiple flag registers (Force Multiple Coils) 16 (0x10) - recording values in multiple storage registers (Preset Multiple Registers)
