Description
Decimal Bit
(Octal Bit)
Word
Word 13
Bits 00-07
(00-07)
Low Alarm bits for channels 1 through 8 respectively. Each bit
represents an alarm indicator for that channel. When the bit is set, the
value of that channel is below the low alarm value.

Word 14
Bits 00-07
(00-07)
High Alarm bits for channels 1 through 8 respectively. Each bit
represents an alarm indicator for that channel. When the bit is set, the
value of that channel is above the high alarm value.

Bit 00
Offset Calibration Complete (O). When this bit is set, the offset
calibration request was successfully completed.
Bit 01
Gain Calibration Complete (G). When this bit is set, the gain
calibration request was successfully completed.
Bit 02
Save Complete (S). When this bit is set, the “save calibration values
to EEPROM” was successfully completed.
15
Bits 03-05 Not used
Word 15
Bit 06
EEPROM Fault (EF). When this bit is set, the calibration values could
not be saved to EEPROM.
Bit 07
Calibration Fault (CF). When this bit is set, the module could not
perform offset or gain calibration. This bit is set when a save is
requested.
Bits 08-15
(10-17)
Calibration Inhibited. Each bit represents a channel that was not
calibrated, either due to an error or a user request. If the channel was
requested not to be calibrated, these bits confirm that request.
In this chapter you learned the meaning of the status information that the
input module sends to the processor. Chapter Summary
