Figure 14-3. Data Log Mode Triggers
Level Triggers
Level triggering initiates a data log based on the value of an internal variable. The variable can be a
minimum or maximum value and can be specified to trigger a record when the monitored variable crosses
a minimum threshold from above, or a maximum threshold from below. A minimum and maximum
threshold may also be selected for the monitored variable, causing the monitored value to trigger a record
when it rises above its maximum threshold or decreases below its minimum threshold.
Level triggers are configured in BESTCOMSPlus on the Level Triggers tab (Figure 14-4) in the Data Log
area of the Report Configuration. The Level Triggers tab consists of a list of parameters that can be
selected to trigger a data log. Each parameter has a level trigger enable setting which configures
triggering of a data log when the parameter increases above the upper threshold setting or decreases
below the lower threshold setting. The parameters available to trigger a data log are listed below.
