17-24 Not used (0)

Where: PU = Power up bit

OR = Out of range bit

IS = Invalid scaling bit

RTS = Real time sampling bit

HF = Hardware Fault

EE = EEPROM status bits

CS = Calibration status bits

These bits are set (1) at approximately the input range limits selected (Table NO TAG).

In this chapter you learned the meaning of the status information that

the input module sends to the processor.
