res 1) I've started this morning a long-run-test to make sure it's the OPC task. Hopefully it is, than I can blame on their developer ;-)
2) I open my references in the beginning, store them in a global var and use them afterwards in different sub's. When the prog is stopped, I will clean up the references. BTW, I've also been told, that I should close any "local" reference, so to say, when I use the global ref, set via attribut their value, I should have to close the outcoming ref-wire of these attribute as well. Is thsi correct? At least, if I do so, some of the references became invalid for further use... nevertheless, tia for your suggestions! Peter
