This area contains the following fields:
- All Hi/Lo Alarms -
This read-only field displays the enabled status of all high and low alarms in
the module. For example, external logic may be used to disable all alarms
during start-up or shutdown. This field shows the result of that logic.
-
PV/Mean Alarms - This read-only field displays the enabled
status of all PV and Mean alarms configured. This field will always be the same
as "All Hi/Lo Alarms."
-
StDev/CV Alarms - This read-only field displays the status of
all StDev and CV alarms configured. If the PV or MEAN exceeds its limit, and
the check-box below is checked, then the StDev and CV alarms will be disabled.
-
Disable Std Dev and CV Alarms when PV exceeds limits - This
check box is used to enable or disable whether the PV or MEAN (as selected in
Left Operator Variable) exceeding its limits, will cause the Std Dev and CV
alarms to be disabled.
