If the bit Kn in the variable status is set it indicates that an error has occurred in variable n. A variable error is given
when the measuring value is outside of the linearization, e.g. in consequence of a sensor break down or of a short
circuit in the line.
If a bit Mn in the module status is set it indicates that an error has occurred in the data logger. Valid is:
M1 = 1: EEPROM - error
M5 = 1: RTD - error
M2 = 1: FLASH - error
M6 = 0: (currently not occupied)
M3 = 1: ADC - error
:
M4 = 1: configuration - error
M16 = 0:(currently not occupied)
