I'm thinking about how to help a customer tonight and I've got an idea, but I don't know if it's possible.
I've used the Data Logger on a Red Lion HMI project to make trend graphs for temperature on a plastic extruder... and it's very cool. But I've never worked with the logged data beyond just the graph. I don't know if I can:
1. Turn the logger on when an analog value passes a threshold, and off when it falls below the threshold. (seems likely)
2. Calculate the Mean Average for all the numbers logged since 8:00 am and display that number on the screen. (This is the basis of the whole project.)
I know I could import the data into Excel and work with it any way I want. I just don't have that option where the HMI will be located, and this needs to be a running number that gets updated and displayed at least once a minute.
So do Red Lion HMIs have the capabilities to work with the data in a fixed way like this?
