Add one of 24 predefined Operator Messages (see Section 4.4.5) or one User-Defined
Message to the alarm event log. If '<user defined>' is selected, a data entry keyboard
appears to enable the message to be entered – see Fig. 4.6, page 42. The selected or
user-defined message is displayed briefly on screen. If Operator Message annotation is
selected (see Chart Annotation below) the message is also added to the chart.
Note. When the instrument is in Historical Review mode, Operator Messages generated
are added at the current time, not the time indicated by the cursor.
If an alarm or operator message is obscuring part of a chart trace, use the Chart
Annotation option to hide or display alarms and messages on the screen.
Select the annotation required.
The possible combinations are:
– No annotation (Alarms and Operator Messages both disabled)
– Alarm annotation only
– Alarms and Operator Message annotation
Operator Message Annotation cannot be enabled unless Alarm Annotation is also
enabled.
Notes.
• If more than 15 icons are present on the screen, chart annotation is disabled
automatically.
• When chart annotation is disabled, new operator messages and alarms are still added
to the Alarm Event log – see Section 2.7.
Use 'Screen Interval' to change the amount of data displayed on the screen. A longer
screen interval displays more data, a shorter screen interval displays data over a shorter
time period, but in more detail. In both cases, the full trace is preserved by plotting the
maxiumum and minimum samples for each display point.
Longer interval =
better overview
The screen intervals available in the menu are determined by the faster of the primary and
secondary sample rates set for the process group during configuration – see Section
4.5.1. Unavailable screen intervals are greyed-out.
Table 2.1 shows the relationship between sample rate and screen interval for the two chart
types.
Notes.
• A 'Please Wait' message appears while the instrument retrieves data from storage.
• Selecting a different screen interval does not affect the rate at which data is sampled.
• When in historical review mode, changing the screen interval causes the time at the
cursor position to change.
