The change flag register states will remain true until the flags are cleared by the Modbus
master by writing a logical ‘1’ to the specific flag.
 Change flags can have the following binary values:
1 – true
0 – false
 If a set point, device setting or offset value is changed by the user the corresponding
flag will be set and it has to be cleared by the Modbus master again by writing the flag
to 0.
