Alarm Banner

[jcjelektro]

Hello

Is it possible to make a Alarm banner (With the alarm text included)

One way is to create a script in the alarm server and then write the alarm text to a tag. Then associate that tag with an AnalogNumeric box on your screen. What ever is in the tag is then displayed.

Code: Select all

    public partial class AlarmServer
    {
		
		void Default_AlarmItem0_AlarmActive(System.Object sender, System.EventArgs e)
		{
			Globals.Tags.Tag1.Value = "My Alarm Text";
		}
		
		void Default_AlarmItem0_AlarmAcknowledge(System.Object sender, System.EventArgs e)
		{
			Globals.Tags.Tag1.Value = "";
		}
    }

To continue this topic : I would like to know how can I write on a tag (string) the last active alarm appears to display it on a "text baneer". Could you help me?

You can create a banner (that shows the first active alarm).

Add a alarmviewer that you remove the column headers from and set the number of rows to 1 and handle set the filter option to hide normal alarms.

Below is a example I made from the alarm sample included in iX.

I tried this solution but I can't modify the background color of the "alarm banneer" and it stays white... And I don't want white...

Sorry, the first poster just asked for a alarm baner

No there is no way of changing the background color in this version, but from what I have heard from Beijer there will be more options avalible for the alarmviewer in future releases.

Yes but now, how can i do to have the last alarm appears on a string tag?

The below code will write the text "My Alarm Text" when AlarmItem0 becomes active. If you do that for each alarm, then the last active alarm will have its text displayed in Tag1.

Code: Select all

    public partial class AlarmServer
    {
      
      void Default_AlarmItem0_AlarmActive(System.Object sender, System.EventArgs e)
      {
         Globals.Tags.Tag1.Value = "My Alarm Text";
      }
      
      void Default_AlarmItem0_AlarmAcknowledge(System.Object sender, System.EventArgs e)
      {
         Globals.Tags.Tag1.Value = "";
      }
    }

But with this script code, if the first alarm is acknowledge, the string tag will be ' ' whereas the second alarm is active. I just want to read the first active alarm on the alarm viewer objet.

You are correct, there can be multiple alarms active, and that is why there is no active alarm tag. You are going to need to create an array and keep track of the alarms and when they are acknowledged or not acknowledged.

You can create a script module with a C# array and populate the array with any/all active alarms. Then when an alarm is acknowledged you will have to remove that item from the array.

You can use the AlarmItem0_AlarmActive and the AlarmItem0_AlarmAcknowledge events to populate/remove the array values.
