Appendix G - Status Flags

Congrego® uses an 8-bit unsigned integer for its status flags. The upper 3 bits represent the general status, while the remaining bits provide further detail of the status.

Bit	7	6	5	4	3	2	1	0
Status Flag	Good	In Calibration	Fault	Unused		See Below

Good Status Codes (Bit 7 set)

All OK	128	Data has been captured with 100% capture rate.
Sufficient	129	Data has been captured with less than 100% capture rate, but still above the capture threshold.
High Alarm	130	Captured value is above or equal to the high alarm threshold.
Low Alarm	131	Captured value is below or equal to the low alarm threshold.

Calibration Status Codes (Bit 6 set)

In Calibration	64	Data has been flagged as in calibration with 100% capture rate.
In Calibration (Sufficient)	65	Data has been flagged as in calibration with less than 100% capture rate, but still above the capture threshold.

Fault Status Codes (Bit 5 set)

Instrument Fault	32	The instrument has reported a fault code.
Communications Fault	34	There was a problem communicating with the instrument. Either the instrument produced an invalid response, or did not respond within the timeout period.
Out of Service	36	The channel has been flagged for maintenance and is currently out of service.

Low Capture Status Codes (Bits 5-7 unset)

No Data	0	No data has been captured (0% capture rate).
Not Enough Samples	1	Some data has been captured, but the capture rate is below the threshold.
