Warning Message Examples
Message Meaning
Warning: Voice word TEH is not
in Voice.TXT file
The misspelled word TEH in the VoiceSpeak() instruction is not found in
Voice.TXT file and will not be spoken by the voice modem.
Voltage calibration failure!
Loose wire probably of a bridge sensor such as a wind vane or pressure
transducer
10.5.4.2 SkippedScan
Skipped scans are caused by long programs with short scan intervals, multiple
Scan() / NextScan instructions outside a SubScan() or SlowSequence , frame
errors, or by other operations that occupy the processor at scan start time.
Occasional skipped scans may be acceptable but should be avoided. Skipped
scans may compromise frequency measurements made on terminals configured
for pulse input. The error occurs because counts from a scan and subsequent
skipped scans are regarded by the CR6 as having occurred during a single scan.
The measured frequency can be much higher than actual. Be careful that scans
that store data are not skipped. If any scan skips repeatedly, optimization of the
datalogger program or reduction of on-line processing may be necessary.
Skipped scans in Pipeline Mode indicate an increase in the maximum buffer depth
is needed. Try increasing the number of scan buffers (third parameter of the
Scan() instruction) to a value greater than that shown in the MaxBuffDepth
register in the Status table.
10.5.4.3 SkippedSystemScan
The CR6 automatically runs a slow sequence to update the calibration table.
When the calibration slow sequence skips, the CR6 will try to repeat that step of
the calibration process next time around. This simply extends calibration time.
10.5.4.4 SkippedRecord
SkippedRecord
is normally incremented when a write-to-data-table event is
skipped, which usually occurs because a scan is skipped. SkippedRecord is not
incremented by all events that leave gaps in data, including cycling power to the
CR6.
10.5.4.5 ProgErrors
Should be 0 . If not, investigate.
10.5.4.6 MemoryFree
A number less than 4 kB is too small and may lead to memory-buffer related
errors.
