Use this menu to stop and start recording or change the sample rate for the channels in the
current Process Group.
The Primary sample rate is set typically to a relatively slow rate (depending upon process
recording requirements) and is active during normal process operating conditions in order
to maximize internal memory and external archive media.
The Secondary sample rate is set typically to a faster rate than the Primary sample rate and
may be selected manually in order to record the maximum amount of detail during, for
example, an alarm condition.
The rates are set during configuration – see Section 4.5.1.
Notes.
• Switching between the primary and secondary sample rates does not affect the screen
interval in the Vertical and Horizontal Chart views or the screen duration in the Circular
Chart view.
• When the channels are set to 'Stop' the instantaneous values in the associated
indicator are displayed in red and, after the end of the next sample period, no further
samples are plotted on the associated traces.
• Digital recording channels can only be set to 'Stop' or 'Go'.
• Recording control can also be implemented using digital sources – see Section 4.5.1.
If selected, the date of the oldest unarchived data is set to that of the oldest data in the
internal flash memory. This allows all data in the internal memory to be re-archived to
external media.
Note. Ideally, a blank media storage card should be inserted prior to selecting this
function.
To re-archive data:
1) Insert archive media, with sufficient free space, into the instrument.
2) Select 'Stay Offline' from the 'Select data to be archived' box that appears.
3) Select 'Reset archiving' in the Setup Menu.
4) Select 'On-line' in the Setup Menu.
5) Select data to be archived (if >1 day of data in internal memory) and press
Places the archive media on-line, starting the archiving process.
Notes.
• The On-line function is disabled (greyed-out in the Setup Menu) if no archive media
card is inserted or the instrument has been placed in Historical Review mode.
• When an archive media card is inserted and there is <1 day of data in internal memory,
the 'Select Line Status' dialog box (left) is displayed, giving the user the choice of
placing archiving on-line or remaining off-line. Archiving is placed automatically on-line
in 10 seconds unless 'Stay Offline' is selected.
• When an archive media card is inserted and there is >1 day of data in internal memory,
the 'Select data to be archived' dialog box (above left) is displayed. Select data to be
archived and press
Once selected, all data within the selected time frame is archived. Older unarchived data
remains in the internal memory buffer until overwritten by newer data but is not available for
archiving unless 'Reset archiving' is selected.
