Combination Algorithm
If using more than 1 sensor, select how the enabled sensors' values are to
be combined to determine the microblock's output value. When the
calculation is performed, only sensors with a valid value are included.
COV Increment
To reduce Rnet traffic, you can force the microblock to update its output only
when the sensed value changes by more than the
COV Increment
.
Show on Sensors
Select
Local Value
to have each enabled sensor display its individual sensed
value, or
Calculated Value
to have each sensor display the value determined
by the
Combination Algorithm
.
Display Resolution
Defines the resolution of the value to be displayed on the sensor. For
example, 1 displays only integers (example: 74) and 0.5 displays values to
the nearest 0.5 (example: 74.5).
Input Smoothing
If the raw value from the sensor changes frequently, you can select one of
the following options to send out an average of several readings on the
output wire.

Check the zone sensor screen(s) that you want this microblock's value
displayed on.
Input Resolution
The increment by which the microblock updates the value on its output wire
in a running system.
The
Resolution
format is used to truncate the microblock’s actual value. For
example, if you enter a value from:
•
0.1 to 0.9, the wire displays 1 digit to the right of the decimal
•
0.01 to 0.99, the wire displays 2 digits to the right of the decimal
•
1 or greater, the wire displays a whole number
The
Resolution
value determines the increment by which the present value is
updated. For example, if you enter:
•
.2, the wire displays 8.4, 8.6, 8.8, ...
•
.03, the wire displays 5.09, 5.12, 5.15, ...
•
10, the wire displays 30, 40, 50, ...
