Alarm Threshold General Properties
The alarms and messages inserted into the 'Alarms List' are equipped
to have one or more intervention thresholds according to the functions
to be carried out. The threshold interventions determine the alarm's or
message's behaviour when the defined threshold values are reached or exceeded.
The Threshold properties can be activated in the editor through the tree
structure of each single Alarm.
To modify the general settings of the alarm's thresholds, select the
threshold with the mouse and use the Movicon 'Properties
Window'.
Threshold Name
The name of the threshold to be configured is defined in this edit box.
The name of the threshold will be displayed in the alarm window instead
of the "Alarm Text" if not previously defined. The displayed
text in Alarm Window will be composed according to alarm type as follows:
Alarm with
associated variable or Alarm generated by variables with the same name
For further information see the
chapter on "Alarm
General Properties"
Alarm as Template
For further information see the
chapter on "Alarm General
Properties"
Alarm Area
This editbox allows you to associate
the Alarm or Message in question its own area if necessary.
The alarm will then be displayed
for viewing by activating the chosen area in the "Alarm Window".
|
When an alarm
is used as a template: if the Alarm's "Alarm Area"
property is left empty and the variable associated belongs
to a variable group, the alarm will be created belonging to the
area with the same variable group name. For instance, associating
an digital alarm as template to the "VAR00001"
variable inserted in "Group1", the alarm will be created
belonging to the "Group1" area.
Further
more if the variable is inserted in a sub-grop, the alarm area
will obtain the name composed by those in the group separated
by the "." . For example if the "VAR00001"
variable belonging to "Group1" is inserted in "Group2"
, the alarm will then belong to the "Group1.Group2"
area.

Alarm Text
This box is used for entering
the text string that will build the effective text of the alarm
referred to the selected threshold. This cobe permits you to select
a text from those inserted in the project's String resource. In this case
the text may be subject to the Change Language functionality. The
text will be composed and displayed in the Alarm Window according to alarm
type:
Alarms with
associated variables or Alarms generated by homonym variables
Alarms as
Templates
|
It
is possible to display the value of a Variable within the text
inserted in the "Alarm Text" property using the following
syntax:
%(VariableName)
for
example, when needing to display the value of VAR00001 in the
Alarm text, the string will be composed as:
Alarm
Title %(VAR00001)
Having
done this, the moment an alarm is triggered (ALLARM ON event)
the variable value is dynamically displayed in the Alarm Window,
if opened at that instant, and recorded in the Alarms Historical
Log at the same time.
If
the variable value is subjected to another change after the Alarm
ON event, the text will continue displaying the same value the
moment the Alarm ON was triggered.
The
moment in which the cause of the Alarm is resolved generating
the "ALARM OFF" event, the value of the variable which
is recorded and displayed in the Alarm Text is the one it has
in the same event instance, therefore if it changes again the
new value will be displayed.
As
regards to the ACKNOWLEDGE (ACK) and RESET events, the variable
value displayed in the alarm text refers to the ON or OFF event
deriving from the ACK or RESET.
In
case in which a an ID String from the String Table has been associated
to the "Alarm Text" property, the %(VariableName) syntax
will have to be inserted in the text of the string in the Project's
String table. |
|
In cases where the alarm text has to support
the multilangage Alarm Log and Runtime it must contain special
ID-String $(ID-String) directly. For example, if you need to insert
the "VAR00001" variable value in the text that contains
the "String01" ID-String, the text to be set in the
Alarm Threshold's 'Threshold Name' or 'Alarm Text' property
will be: $(String01)%(VAR00001). Therefore "String01"
ID-String should already be in the String Table with the
text translated in the different languages, for example: "Allarme
Motore 01 - Ampere=" in Italian and "Motor 01 in Alarm
- Ampere=" in English. When the variable obtains the
50 value in runtime, the alarm text will result as "Allarme
Motore 01 - Ampere=50" in Italian and when the language is
changed to English it will result as "Motor 01 in Alarm -
Ampere=50".
In particular cases can be considered where
various ID-Stings and Variable values are concatenated for the
"Alarm Text" property for example:
|
|
The concatenation of more than one variable
value (eg. "VAR00008 = %(VAR00008) and VAR00003 = %(VAR00003)"
and ID-String (eg.
"@(ID-Str01) - @(ID-Str02)") is
not supported when the Multilanguage Log Management is active.
In this case you will need to use a mixed syntax such as::
If you use the Alarm as a Template, the
Variable Name can also be inserted in the String Table as an ID-String
as well. |
Alarm Help
This box, whose use is not obligatory, allows you to type the text string
which will constitute the eventual alarms help guide. The Help guide will
be available to the operator during runtime by double-clicking on the
alarm or activating the appropriated information button. The box allows
you to select the text from those inserted in the project's string resource.
In this case the text may be subject to the Language Change functionalities.
Duration
Message Format
The message to be filed in the 'CommCol' column of the Historical Log's
'Alarms' table is entered in this property. The message is recorded only
on an event of 'Alarms Off'.
The message may only include the following special codes:
%D
= Duration of alarm in days
%H
= Duration of alarm in hours
%M
= Duration of alarm in minutes
%S
= Duration of alarm in seconds
If this property is left empty, Movicon will automatically insert the
total alarm duration with the following string:
Total Duration 0,00:00:00
where 00:00:00 indicates the alarm's duration in days, hours, minutes
and seconds.
Read
Access Area Level
By using this property you can setup the Access Level mask needed for
displaying the alarm in the "Alarm Window". When the Access Level
mask of the user currently logged on does not correspond to the control's
settings, the user will not be able to see the alarms. The "0000"
and "FFFF" settings make the object accessible in read to any
user.
The historical logging operations of the alarms are carried out independently
of the access rights of the user logged on at that moment.
For further details on 'Access Masks' please refer to the "User Levels and
Access Levels" paragraph.
Write
Access Area Level
By using this property you can set the Access Level mask needed for
executing, for instance, an alarm acknowledgement and reset. When
the Access Level mask of the user currently logged on does not correspond
to the control's settings, the user will not be able to execute any command
operations associated to the alarms. The "FFFF" level makes
the object accessible in write to any user.
For further details on 'Access Masks' please refer to the "User Levels and
Access Levels" paragraph.
