Hello everyone,

I am currently working on a new project, and I would like to have the possibility to select the trend points to graph stored data on a CSV file.

I managed to store the values on a Segmented Circular log, allowing me to store and read up to a year of data. Furthermore, I managed to go back in time using a numeric input with Date format.

However, all this is possible for on a graph object with up to seven variables. I would like to have the possibility to select the trend pointers (60 variables approx), and graph just the ones I am interested to.

I am working with TIA PORTAL V15, with Comfort Panels and WinCC Advance for the PC based version.

Any ideas how to do this?

Thanks in advance.

Hello.

Thanks for your repply.

I am using a 1510 CPU with a RT Advanced HMI. I have several trends which log data into CSV files. What I need is to be able to introduce a date into a field and to see the trend values from that date ahead. In the alarm view you can do it by defining a date_and_time variable and it's very easy. In my case, no so easy with trends. 

I was looking to the long term data archiving application example but I think it's not what I need.

Best regards.
