Property Description
select a compare data point by filling in the
the table.
Scenarios that may assist you in understanding how to use
this property are included in the Comparison Functions
section.
The output function for the Analog Function Block. This
determines the operation the Analog Function Block will
perform each time its data points are updated, and how the
value of the Analog Function Block’s output data point will
be determined.
For descriptions of the output functions you can use with
your Analog Function Block, see Output Functions.
The minimum value that the output data point can be
assigned.
The maximum value that the output data point can be
assigned.
The delay, in seconds (0.0 to 6553.0), that must elapse
between updates to the Analog Function Block’s output data
point. This may be useful if you have multiple input data
points, as setting a long interval here could cause the Analog
Function Block to only update the output data point when
all inputs have been received. If you use the default value
of 0.0, the Analog Function Block will update the output
data point each time any of the input data points are
updated.
The number of previous averages from which a straight
average is calculated. For example, if you set this property
to 2, the average equals the sum of the last two calculated
averages divided by two. This means that if the last
calculated average was 20, and the previous calculated
average was 30, the average value sent to the output point is
25.
Note: This property is only applicable if you set
FN_AVERAGE.
A value to define the behavior of the output data point when
an override request is received for the Analog Function
Block. The valid range for this property is any value within
the defined limits of SNVT_override. Enter
OV_SPECIFIED to assign the output data point an override
value when this occurs. You can specify the value to be
used by filling in the
If you do not fill in this property, the output data point will
maintain its last setting when an override occurs.
