          Hi Shifana,

           

          If I am understanding your question correctly, you want to use C# to change an attribute value. If so, you should look at the AF SDK. I put together a short introduction to getting started with the SDK, which is a good place to start:

           

          My New Getting Started with PI SDKs Blog Series

           

          From there you basically will want to use the SDK to retrieve the element, then update the attribute. How you update the attribute will depend on it's type, but it is not too complex.

           

          If your question is something different please let us know. If you get stuck, feel free to post more questions or do searches here on PI Square, there is a ton of information. 99% of the issues people have are most likely already answered here!

           

          Good Luck!

            Back to your question:

             

            To change an attribute value,

            • First you need to find the element you need, you can do this by using either FindElement or FindElements methods, there are many and you should be able to find the one you need here: AFElement Methods.
            • Then you need get the attribute(s) you want to change (you can use the Attributes Property (or in you have a lot of elements, you should look at AFElement.LoadAttributes Method to make partial loading).
            • Once you have the attributes, you need to use the SetValue method to change the attribute value. AFAttribute.SetValue Method (AFValue) .  You should read the remarks carefully on this one.
            • Finally, once your change is done, you need to do a CheckIn on the Element that contains the attribute. AFElement.CheckIn Method .  Remarks on the Checking Method are also worth to read.

             

            Hope this helps and please let us know in case you have more questions and let us know how you are progressing.
