WCC3.EXE SCREEN DESCRIPTIONS
BINARY GLOBAL SCREEN
ALARM MODE
BINARY Global #: 2 Name is GB5
Description: Linux Global On Message #: 1 On
Mode: 4 Alarm Off Message #: 2 Off
Value is OFF if GA1 is active alarm and Current in Alarm and Alarm acknowledged
In Local Set this global defaults to Last Value.
ALARM
Set Condition: None Type: 1 Message 5 Global Alarm
HOME for menu
Mode: 4 Alarm
Specifi es the mode used to generate the ON or OFF value of the
binary global. Because this is a choice fi eld, the following list of
available choices will be displayed at the bottom of the screen:
Alarm-by-Class, One Shot, Clock, Delay, PWM,
Lead-Lag>
Make your selection by pressing the once for each
choice until the desired mode has been selected, and then press
. Whenever you change modes, you must fi rst clear the
existing screen by using the feature.
The Alarm mode causes the binary global to generate an ON or
OFF value based on either an active or non active alarm that has
been either acknowledged or not acknowledged.
Value is ON if 1A2 is active alarm
and [Current in Alarm]
and [Alarm not acknowledged]
In the above example, the ON or OFF value of the global binary
is determined by the alarm status of analog input #2 on satellite
controller #1. When an alarm occurs, the alarm message will blink
on the Analog Input Screen. After the alarm has been acknowledged,
one of two things will happen. If the value of the analog input is
presently within the alarm limits, the alarm message will disappear.
If the value of the analog input is still outside the alarm limits, the
message will stay on the screen, but it will quit blinking.
The term “active alarm” means that the alarm has not been
cleared. It is either a “blinking” or “solid” alarm within the
system.
The conditional statements are in a “choice” fi eld and therefore the
choices are shown at the bottom of the screen.
NONE>
Make your selection by pressing the once for each
choice until the desired event type has been selected, and then
press
.
[NONE]
[NONE] When NONE is selected for both of the choice
fi elds, the value of the global binary will change
state (go ON in the above example) whenever the
analog input specifi ed on this screen is in an alarm
condition, either unacknowledged (“blinking”
alarm) or acknowledged (“solid” alarm).
[NONE]
[Alarm
Acknowledged] When these choices are selected, the value of the global
binary will go ON when the alarm for the analog input
is acknowledged while the value of the analog input is
outside the alarm limits. That is to say, the global binary
will go ON whenever this analog input has “solid”
alarm condition.
Binary Global Screen’s WCC III Logical Address is GBXXX, where GB = Global Binary and XXX = Global Binary Address
