WCC III Technical Guide 3-144
Data Pattern: _____
Specifi es the number of signifi cant digits for analog global values
displayed by the system. Because this is a “choice” fi eld, the list of
available choices will be displayed at the bottom of the screen:
<x,xxx, xxx.x, xx.xx, x.xxx>
Make your selection by pressing the <space bar> once for each
choice until the desired default choice has been selected, and then
press
<Enter> .
Units of Measure:
Specifi es a message number to be used throughout the system to
reference a textual message which is displayed with the values
associated with this global. For example, if units of measure
message #4 is Deg F, and the units of measure message for the
specifi c analog global is degrees Fahrenheit, then the units of
measure would be 4.
In Local Set this global defaults to
Because this is a “choice” fi eld, the list of available choices will be
displayed at the bottom of the screen:
< LAST, FIXED >
Make your selection by pressing the <space bar> once for each
choice until the desired default choice has been selected, and then
press
<Enter> .
The term local set means that communication is lost between
the MCD and the satellite controllers. If the MCD stops
communicating, the global analog values will be gone. This
input allows you to specify a default value for the global
analog if the MCD quits communicating. You may input a fi xed
number, or you may choose to select LAST VALUE. If LAST
VALUE is chosen, the global analog will default to the value it
had when communications with the MCD were lost.
Map From:
Specifi es an analog point address that acts as the input signal
source for the output valve.
Extend Data to next Table
Each look up table can hold up to 60 sets of data. If you have an
application which requires a larger look up table, the data may be
extended to the next look up table.
Mode
Because this is a “choice” fi eld, the list of available choices will
be displayed at the bottom of the screen:
<Averaged, Sorted, Integral, Math, Look Up,
External, Dual Valve, Proportion, Dual Ramp,
Multi-Proportion, Pulse Start>
Make your selection by pressing the <space bar> once for each
choice until the desired mode type has been selected, and then press
<Enter> . One of the following screens will appear, depending on
which choice you select:
Averaged List Math Function
Sorted List Look-Up Table
Integral External
Sliding Window Dual Valve
Average Proportion
Accumulation Dual Ramp
Multi-Proportion
Pulse Start
CAUTION: Select the mode before entering any other data on
an Analog Global Screen. If other information is entered before
the mode is selected, there is a chance that the global analog
will not perform properly. If data has already been entered and
you want to change the mode, you must fi rst clear the screen by
using the <Ctrl><Home> feature, and then exit to the Global
Analog Summary Screen before re-entering data.
If the analog input is unavailable, then use 70.0 as a
default value.
If the input value is not available or invalid, then the value of this
global analog will default to this number.
