I use this to log data and display it in various ways.
If you need an HMI then this is not really what you want to use. I have well over a 1,000 lines of code in my functions and only 3 write to tags and this is because I have Python scripts processing mass amounts of data and then the results are written. Way to much for the PLC to do.
This is truly for displaying info not controlling machines.
