Pasto69 Posts: 12 Rating: (0)	I need another hint... I wrote a script that put 6 analog value on a .csv file for production quality archive... Now i need to make a page on wincc flex RT where i can take this value (with a script) and put it on a trend for check the production... How i can translate the value on a chart in RT? I can't use the PLC memory becouse i have a S7-226 (trought ethernet) and it is very low on memory... Someone have a solution for me?

I suppose you made some tags to get the values out of the plc. actually you don't even need the script i think (or no need to make a csv -file) you can read them @ once ... Would that be a hulpful to explain that ...

Possibility You can use thedatalogs of WinCC flexible and the system function "Log Tag". If you need the actual value of a tag, then you can storethecurrent value in a archive which you can project in WInCC flexible. 2. Possibility You can create your own script in which you store all relevant tags. If you want to show the data in an trend view, then you have to save the data in the right order of an WinCC flexible archive. Maybe this FAQsis very helpful: http://support.automation.siemens.com/WW/view/de/26190516 If you have an PC, then you can use this method: http://support.automation.siemens.com/WW/view/en/35929465 Bye

Pasto69 Posts: 12 Rating: (0)	Ok but... i don't wish to use @archives and even if i use it i have to build a new file instead the one created from @archives right? It's possible to have a trend of an tag array? And finally, if nothing like me, is possible to draw graphics primitive onscreen like line? how? Thanks
