With a C# program, How I can know the date about which a tag was written ?
Thanks for your help.
Can you give us more information about what PI development tool you will be using? If you are asking which development tool, I would suggest researching the PI AFSDK.
Do you want to know the event was written correctly?
If the write action fails, you can get an exception and check the error message by PI AFSDK.
For make sure the new event was written, you can read it again by read function and check the returned value.
But there is a possibility that new event has not written yet. So wait a few time and read it again if it has not come yet.
