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 82) 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.
