Hello,

We would like to make a alarm filter in VSTA. Is it possible?

Hi,

what are you trying to do?
Did you take a look on the Alarm Message List Filter picture type?

If this does not fulfill your requirements, there is the possibility to use the filter of a picture switch function to the Alarm Message List Picture in VBA/VSTA.

You have to create a picture switch function to your alarm picture in the Editor (in my example "dummyfilter", see code below), where you can set some predefined settings. This settings can be manipulated via VBA/VSTA in the Runtime via the DynProperties of the function (also see code below).

        //Function to get the filtered alarms
        public void Macro_GetFilteredAlarmItems()
        {
            zenOn.IAlarm zAML;
            zenOn.IAlarmItems zAML_Items;
            zenOn.IAlarmItem zAML_Item;

            Int32 i; 

            string[] DynProps; 

            zAML = this.Alarm();

            //Show PictFilter DynProperties - Debug (DynProperties can also be shown via XML - Exporting the Function)
            DynProps = (string[])this.RtFunctions().Item("dummyfilter").get_DynPropertiesEnum("PictFilter");
            foreach (string s in DynProps)
            {
                System.Diagnostics.Debug.WriteLine(s);
            }
            
            //Manipulate the function (here the VarFilter is set to "ivar2")
            this.RtFunctions().Item("dummyfilter").set_DynProperties("PictFilter[0].VarFilter", "ivar2");

            //Apply the alarm filter
            zAML_Items = zAML.AlarmItems("dummyfilter");

            //iterate through the filtered alarms
            for (i = 0; i < zAML_Items.Count; i++)
            {
                zAML_Item = zAML_Items.Item(i);
                PrintAlarm(zAML_Item);
            }

        }

        //Function for printing the alarm information 
        public void PrintAlarm(zenOn.IAlarmItem myAlarmItem)
        {
            System.Diagnostics.Debug.WriteLine("Comes " + myAlarmItem.Timecomes + "\r\n");
            System.Diagnostics.Debug.WriteLine("Goes " + myAlarmItem.Timegoes + "\r\n");
            System.Diagnostics.Debug.WriteLine("Ack " + myAlarmItem.Timequitted + "\r\n");
            System.Diagnostics.Debug.WriteLine("Text " + myAlarmItem.Text + "\r\n");
            System.Diagnostics.Debug.WriteLine("Variable " + myAlarmItem.Name + "\r\n");
            System.Diagnostics.Debug.WriteLine("Value " + myAlarmItem.Value + "\r\n");
        }

Take also a look here how to get the DynProperties:

Hello Bernhard,

We have a batch process where every batch have a specific number.
In a database table insert I the batch number with Start and End Time.

Now will we look wich alarm have occurred by a specifiek batch number.

My tought was: make a function in vsta who, adjust a filter where the results place in the alarm message list.

Hi,

yes, this should work by adapting the appropriate DynProperties of the picture switch function.

If you take a look on the XML Export of a picture switch function you see these properties:



Which you also get via DynPropertiesEnum (property and datatype)
