F&F LE-03MQ Modbus energy counter

[buuuudzik]

Thanks for your very helpful and fast answer Erwin. If it is about this function code and possibility to read and write parameters(function codes 03 and 16) for this counter there is a little problem because the measured values registers starts from register 0 and parameters starts also from register 0 so I don't know how can I use parameters when I will use measured values(they are more important).
