The slope of the measured value (MV) is monitored in
this mode.
An event is generated if, in the given timeframe (Delta
time), the measured value increases or decreases by
more than the specified value (Delta value). No further
event is generated if the value continues to experience
such a steep increase or decrease.
If the slope is back below the limit value, the alarm
status is reset after a preset time (Auto Confirm).
Events are triggered by the following conditions in the
