If a bit is set in the <tare/reset> byte, the corresponding sensor variable is tared or reset respectively. The values
following the <tare/reset> byte are allocated to the writeable variables of the data logger, according to the order of
their appearance. Writeable variables are Setpoint Variables and Digital Output Variables.
