The function that is called only once at the start of the project. What i want to do in this function? For example, open a txt file, read the data to internal tags and closed the file. And i want to do this only onece at start of project. Regards Rafał.

You can create a Global Action, with a cyclic trigger of 1 hour. This is triggerd with the start of the runtime. Here can you execute your actions (open a txt file, a.s.o.). At the end, you set an internal tag, to mark, that the action was already done once. The action is triggerd after an hour again, now can you check at the begin your internal "done"-tag and return from the action, without doing any other thing. But if you would only load some "former"-values from last runtime, to internal tags, it may be possible to use the option "Runtime-Persistenz". Regards Georg Berghof
