Thanks for the help so far guys. I have my screens made, login setup, and now I'm looking at trends. I want to trend a tank temperature, and I do have the trend set up, but I do have a couple questions. I have it set up to log data to an external USB drive.
I'm trending this data. Will this data always trend, or is there a way to set it up so that I can have it trend only when a boolean value is true. This way, when a station is not in use, the data is not being logged.
Does the screen with the trend need to always be on in order for the data to log? I currently am closing the screen on exit to prevent there from being a ton of different screens open and slowing down the HMI. The trend is set up to use history.
Ideally, I would like the boolean value to determine whether or not the data is being logged, and have the trend load that data when you go to the screen containing the trend.
Thanks again.
