Math Operators (>, = =, !=)
The math operators are in a choice fi eld and therefore the list of
available choices will be displayed at the bottom of the screen:
CHOICE (>, ==, !=)
Make your selection by pressing the <space bar> once for each
choice until the desired mode has been selected, and then press
<ENTER> .
Math Operator Description
> The statement is true when the
value to the left of the symbol is
greater than the value to the right.
(Or, the statement is true when
the value to the right is less than
the value to the left.)
= = The statement is true when the
value to the left is equal to the
value to the right.
!= The statement is true when the
value to the left of the symbol
does not equal the value to the
right of the symbol.
Hysteresis
This entry allows you to add hysteresis to the equation:
Value ON if 1A4 > 2A5 Hysteresis GA2
Default value: 25 20 5
NOTE: The Value is On if and Hysteresis line must be
addressable points. If left blank, the program will use the
default values.
In the above example, the value of 1A4 must be greater than 2A5
by the value of Hysteresis before the global will go ON. Also, the
value of 2A5 must be less than 1A4 by the value of Hysteresis
before the global binary will go OFF. If the analog value that is
entered here (GA2 in the above example) is invalid or unavailable,
the default value under the analog value will be used as the amount
of hysteresis. You may also use [analog] point addresses such as
analog inputs or global analogs.
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.
