Getting Value of the Properties

[mtalhagaoglu]

Hi,

I am able to get the list of properties for the objects, but I am not able to retrieve their values. Is there a way to do this? I can even update or create the objects, but reading their values is also important and should be possible.

Hi @mtalhagaoglu  
Is this regarding SEAL script ? 
If so, yes you should be able to retrieve the value also. 
Is it values on AS or MP/RP devices you got problem with ?

Hi Stefan,

Yes, this is related to the script part of SEAL.
The method I am using is sdkClient.IAdvanced.GetPropertyValueVariableReference, and the response I get is as follows:

{"failed":false,"message":"","nativeValue":0,"returnValue":{"value":null,"transferRateSeconds":0,"retransmitMinutes":0,"deltaFilter":0,"isNull":true,"isLocked":false,"isRelative":false,"isServerAbsolute":false,"isSystemAbsolute":false,"_dotNetType":"VariablesPropertyReference"},"status":"Ok","trace":""}

I can get string values of the point, such as name and description, but the actual value is always null. It allows me to update it, but reading seems to be the issue.

Additionally, I wasn’t able to get the "Display on alarm" status of an alarm attachment.

Try the attached Demo Script , it might help you.
If you have the below objects on your server you should be able to read the values of different properties with the script, ensure you select the correct data type for the specific property you want to read. 

If you want to read the 'Display on alarm' property for the 'Change of State Alarm' object in the above example you configure the demo script as below ( The attachment is a hidden child object to the alarm named 'Attachment' , and the property to read is 'Popup' , data type = Boolean) 

I hope this helps you

Hi Stefan,

Thank you for the script and your guidance.

The script helped me retrieve the value of the "Analog Value" point, but I couldn’t access the Popup property of the alarm attachment.

"Display on alarm" is bound to this property path:  /Server 1/Change of State Alarm/Test Attachment 1/Popup

"Test Attachment 1" is the name of the attachment, but unfortunately, we can’t see this value in the attachment list of the alarm.

All of their names look like "Analog Value," but the real name can be found the xml file or the alarm's properties popup.

Hi again, 
I tested your setup and have no issue reading binary state of the popup property using the demo script :
