WCC3.EXE SCREEN DESCRIPTIONS
WCC III Technical Guide 3-136
The sampling rate programmed amount of time can be in minutes
or hours. Because this is a “choice” fi eld, the list of available
choices will be displayed at the bottom of the screen:
<Minutes, Hours>
Make your selection by pressing the <space bar> once for each
choice until the desired time frame has been selected, and then
press
<Enter> .
The sampling rate window can be programmed for number of
minutes, hours, days, or samples. Because this is a “choice” fi eld,
the list of available choices will be displayed at the bottom of the
screen:
<Minutes, Hours, Days, Samples>
Make your selection by pressing the <space bar> once for each
choice until the desired time frame has been selected, and then
press
<Enter> .
Integral Mode: Average
There are three integral modes which can be selected by pressing
the
<space bar> until the desired choice appears and then pressing
<Enter> . The following choices are available:
< Accumulation, Average, Sliding Window >
Divisor: 1
Due to memory limitations within the WCC III system, the
maximum value of any global analog is 65,535, and the largest
number which can be displayed on the screen is 9999. The value
of the global analog is divided by this number to lower the number
shown on the screen. The maximum divisor allowed is 9999.
i = n
Global value = (

Di / n ) / divisor
i = 1
This is simply the form of the math equation used to generate the
value of this global analog.
If sampling data is unavailable, use 50 as the default value.
If the input value is not available or is invalid, the value of this
global analog will default to this number.
Range
The system has the capability of generating an alarm if the value
of this global analog is either inside or outside of the desired range.
If inside is selected, an alarm will be generated when the value of
the global analog is within the two limits specifi ed. If outside is
selected, an alarm will be generated if the value of the global is
outside the limits specifi ed. Because this is a “choice” fi eld, a list of
available choices will be displayed at the bottom of the screen:
< None, Inside, Outside>
You may make your selection by pressing the <space bar> until
the desired data pattern has been selected, and then pressing
<Enter> .
Low Limit High limit
The Low and High Limits can be either an Address or a Value.
When you move the cursor to this fi eld, the word Address or Value
will appear. Since this is a choice fi eld, press the
<Space Bar>
until the desired choice appears and then press <Enter> .
If you select “Value” as the choice for this fi eld, you can enter a
number which will serve as the alarm limit. If you select “Address,”
you can specify an address such as an analog input or global analog
to be used as the alarm limit.
Type
Specifi es the priority (or “importance”) level for any alarms
generated by this input. Alarm types range from one (highest
priority) to eight (lowest priority). The system displays and e-mails
higher priority alarms fi rst. (The fi rst fi ve alarm priorities (1-5)
have e-mail-out-on-alarm capabilities.)
Message #
Specifi es a message number which is used by the system to reference
a message which is entered on the Alarm Message Screen.
Reset random data by pressing Ctrl-R
After you enter data on this screen, or after you make any changes
to the screen, you should reset the data. You can do this in one of
two ways when the cursor is at the Home position of the screen.
You can press
<Ctrl><R> or you can select <Action> from the Top
Menu Bar and then select <Reset> . You may also use the reset
feature whenever you want to cause the calculation process to start
over.
