Momentarily it is situated in the project module which I try to trigger in the actions. Furthermore I really can't find winCC in the online help, leaving me a bit sad. Thank you kindlyfor your time.

In WinCC you are advised to place your functions / procedures in a Project or Standard Module. A projectmodule is stored in the project and will be copied when a project is copied. A standard module is stored in the WinCC directory and is available to all projects on that computer only. Functions in these modules can be calledfrom either: a) Global Actions - actions let you assign a trigger for when the script will run; or b) Graphics Designer scripts. For a script that needs to run every 10 mins I would recommend using a Global Action as this is independent of which graphic is open in runtime. fyi, the WinCC manual can be found under START -> SIMATIC -> WinCC -> WinCC Information System Hope this helps some. Regards, Salma
