WCC3.EXE SCREEN DESCRIPTIONS

WCC III Technical Guide

3-164

This second part of the sentence reads as “...when (ANY or ALL) of
the following conditions are met.” If the word “ANY” is selected,
the binary global will take on the specifi c value if at least one of
the statements following the sentence is true. If the word “ALL”
is selected, then the binary global will take on the specifi ed value
if and only if all of the statements following the sentences are true.
The logical equivalent for “ANY” is the boolean function “OR,”
and the logical equivalent for “ALL” is the boolean function
“AND.”

_____ is ON default

true

_____ is OFF default

false

Next on the Binary Global Screen is a list of “statements” which
are used to determine the “trueness” or falseness” of the binary
global. These statements are constructed by entering the logical
address of a particular point. This is best shown by the following
examples:

Value is ON when ANY of the following conditions are met:

W2 is ON

default FALSE

GB5 is OFF

default TRUE

The segment of the screen shown above would read, “Value is ON
when either week schedule #2 is ON or binary global #5 is OFF.”
Note that the word “or” was used to describe the global.

Value is ON when ALL of the following conditions are met:

1K1H is ON

default TRUE

W6 is OFF

default FALSE

This screen would read, “Value is ON when the 1H contact of
satellite #1 is ON and week schedule 6 is OFF.” Again, note that
the word “and” was used to describe the global.

If a value or any of the point addresses specifi ed by the user cannot
be found, then the system will look at the command given in the
“default” column. In other words, in the example given, if week
schedule #6 (W6) cannot be found (i.e., it has not been set up), then
the system will consider the statement “W6 is OFF” to be a false
statement, and therefore it will assume W6 is ON.

In Local Set this global defaults to _____.

Specifi es the state (or value) of the binary global when the satellite
is in the Local Set mode. The satellite is in local set when it has lost
communications with the front end computer.

Since the fi rst fi eld is a “choice” fi eld, the list of available choices
will be displayed at the bottom of the screen:

<Off, On, Last Value>

Make your selection by pressing the

<space bar>

once for each

choice until the desired contact state has been selected, and then
press

<Enter>

.

------------ALARM-------------

Set Condition: None Type: 0

Message 0

The system has the capability of generating an alarm if the value of
this binary global is either ON or OFF.

Set the condition to “None” to not generate an alarm whenever the
Binary Global is Off or On. Set the condition to “On” to generate
an alarm whenever this Binary Global is On. Set condition to “Off”
to generate an alarm whenever this Binary Global is Off.

Because this is a choice fi eld, the list of available choices will be
displayed at the bottom of the page.

<None, Off, On>

Make your selection by pressing the

<space bar>

once for each

choice until the desired event type has been selected, and then
press

<Enter>

.

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.)

The message number corresponds to a message on the ON/OFF
Message Screen
.
