5.2 Logging Menu
Use this menu to stop and start recording or switch between the Primary and
Secondary sample rates for 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 page 85.
Note.
Switching between the primary and secondary sample rates does not affect
the screen interval in the Vertical and Horizontal Chart views.
When the channels are set to 'Stop' the instantaneous values in the
associated indicators are displayed in red (color recorders) or white on a
black background (monochrome recorders) 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
Sections 7.7.1 page 84 and 7.8.1 page 93.
Note.
Available only if 'Operator Calibrate' on the I/O Modules configuration tab is
set to 'On' – see Section 7.10.1, page 117.
Manually fine-tune inputs to remove process offset errors or system scale errors.
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.
Insert a blank media storage card prior to selecting this function.
To re-archive data:
1.
Insert archive media, with sufficient free space, into the recorder.
2.
Select 'Off-line' in the Logging menu.
3.
Select 'Reset archiving' in the logging menu.
4.
Select 'On-line' in the Logging menu.
5.
Select data to be archived if >1 hour (Text format) or >1 day (Binary format)
of data in internal memory and press
