* 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)

This meter uses two types of registers, individually addressed<br>
01 05 00 03 01 00 3c 5a<br>
The first is the data register, read-only, using the command code 0x04 to read.<br>
3 Relay Off<br>
The second category is the parameter register, readable and writable, using the command code 0x03<br>
01 05 00 03 00 00 3d ca<br>
read, write parameters using 0x10<br>
