thanks to all Also for someone confused like i was, here is my explanation: Function Trend Control can plot x[],y[] arrays of points from an existing csv file stored on the machine
https://support.industry.siemens.com/cs/ru/ru/view/109481693/en uses a VB script, that takes those arrays, clears existing .csv, writes in a FOR loop to the .csv file (archive), does error messaging along the way then a screen with the Function Trend Control is updated to summarise 1) generate x,y arrays in PLC 2) establish connection to x,y arrays in HMI, historic data - .csv archive 3) copy the VB script 4) add an UPDATE plot button, that calls the VB script and updates the screen with trend 5) add trend and use the archive (historic data)
