Team, I always meet the question. I want get the timestamp of the Pipoint value or status changed. for example, the valve status is close, once it change to open, I want get the timestamp which indicate the change moment. so I could calculate the time for the status. thanks.
and I am using the C# for the program project. it is better if you can provide the solution. in my proposal, I will add event to monitor the status change, but I need exactly time that the change occured.
