Appendix 12 Instrument/Unit Communications Interruptions and Reestablishment
A
40
Apart from the alarm when communications with a unit are interrupted, no alarm judg-
ment is made when there is no data due to an interruption of communications with a unit.
Judgment will be performed all at once when data from the unit is restored after commu-
nications are established, and alarms will occur as alarm criteria are satisfied. Alarm out-
put will be generated at the same timing.
When automatically saving waveform (binary) data, data being saved is also restored
when data is restored on the instrument. However, when using the split save setting,
data in files that have already been split and saved will not be restored. Only data asso-
ciated with files that are currently being saved (i.e., that have not yet been split) can be
restored. When automatically saving data in the CSV (text) format, saved data is not
restored. Additionally, data cannot be restored if the data in question cannot be found on
the media, for example if the media has been changed.
If “NO DATA” is displayed for the data of the object channels for calculation due to a com-
munication interruption or other causes, the data will be not treated as the object for the
numerical calculation.
If the calculation range consists of the data that are displayed as “NO DATA,” the instru-
ment will display “---” on the screen and the numerical calculation result to be saved will
be zero.
Once data has been transferred from the instrument to the Logger Utility, it cannot be
changed during measurement, even if data is restored on the instrument. If you wish to
access that data, load the restored data that was saved on the instrument after stopping
measurement.
