* das sind wohl noch nicht alle Modbus Funktion Codes
es gibt wohl auch Sonderfunktionen die nur bei bstimmten Geräten vorhanden sind hier z.B. 0x10h setzten der UID


  *  RS485 communication interface
  *  TTL communication interface
  *  2 optocoupler isolation input
  *  2 way optocoupler isolation output
  *  A user button
  *  A user LED
  *  A power indicator
  *  A STM32F030F4 microcontroller
  *  2 relay status indicators LED lights
  *  Power supply terminal interface (12V power supply)

===  DDS578R Energy Meter ===
MODBUS-RTU communication protocol Description:
1.the data format: <br>
Address + function code + data + CRC check code<br>
<br>
2.the register type<br>
This meter uses two types of registers, individually addressed<br>
The first is the data register, read-only, using the command code 0x04 to read.<br>
The second category is the parameter register, readable and writable, using the command code 0x03<br>
read, write parameters using 0x10<br>
<br>
3.the data format<br>
Float type data: Read the internal data within the meter in line with IEEE-754 standardv
floating-point number, data format is 32-bit 4-byte single-precision floating-point data format.<br>
<br>
<br>
4、Data register list<br>
