Hi Dojo,
I have a question, that derives from this thread.
I would like to use the alarm state of a view (respective the highest severity of alarms in all views below that view) as variable in an automation script. Is there a method to retrieve that value from a view? This should then finally used to set a value of a property for this view.
My scripts looks like this and is working well with a fixed value instead of the alarm severity variable and includes some exception handling already.
public class Script
{
public void Run(Engine engine)
{
ViewInfoEventMessage[] allViews = GetViews();
if(allViews == null)
{
engine.ExitFail("No views were found");
}
foreach(ViewInfoEventMessage view in allViews)
{
// do the filtering of views you want to update
if(view.Name.Equals("ABC"))
{
UpdateViewProperty(view,"ABC","12345",engine);
}
}
}
public void UpdateViewProperty(ViewInfoEventMessage view, string propertyName, string propertyValue, Engine engine)
{
SetDataMinerInfoMessage request = new SetDataMinerInfoMessage();
request.bInfo1 = Int32.MaxValue;
request.bInfo2 = Int32.MaxValue;
request.DataMinerID = -1;
request.ElementID = -1;
request.HostingDataMinerID = -1;
request.IInfo1 = Int32.MaxValue;
request.IInfo2 = Int32.MaxValue;
SA sa = new SA();
sa.Sa = new String[] { propertyName, "read-write", propertyValue };
PSA psa = new PSA();
psa.Psa = new SA[] { sa };
request.Psa2 = psa;
request.StrInfo1 = $"view:{view.ID}";
request.What = 62;
SetDataMinerInfoResponseMessage response = engine.SendSLNetSingleResponseMessage(request) as SetDataMinerInfoResponseMessage;
if (response.iRet != 0)
{
engine.GenerateInformation($"Update of property {propertyName} on View {view.Name} was not OK");
}
}
public ViewInfoEventMessage[] GetViews()
{
var getViewsList = new GetInfoMessage
{
DataMinerID = -1,
Type = InfoType.ViewInfo
};
DMSMessage[] dmsma = Engine.SLNet.SendMessage(getViewsList);
if (dmsma == null)
{
return null;
}
return Array.ConvertAll(dmsma, input => (ViewInfoEventMessage)input);
}
}
Could you enlighten me?
Many thanks in advance and best regards

I studied the script condition documentation on https://docs.dataminer.services/user-guide/Advanced_Modules/Correlation/Correlation_rule_syntax/Script_condition_functions.html
The script created via the help given above sets the a value for the property "BC_RP21 Alarm" on the view "RP21". So to achieve what I asked in my last comment it might be good to use a script condition to compare, if the highest alarm, that enters the correlation rule (through a filter) is not equal to the actual property value. This would allow us to limit the execution of the script only when the highest alarm severity is above or below the actual severity of the view ( = property value).
Is it possible to compare to values to achieve the following condition:
"highest severity in filtered active alarms" not equal to "property value"
A script condition then might look like this:
max(field(severity)) != property(view.BC_RP21 Alarm)
... or must there be a integer/string value on the right side of the logic equation?
Many thanks and best regards
