Hello, I have a similar problem with WinCC TIA professional (V15.1). in fact: - I have an internal variable (IHM) not a process variable. - I have a periodic action (500ms), that calls a VBScript that read/wrote (using SmartTags function) and trace the new value of my Internal variable - I observed that the value of my internal variable is not changed in the same cycle of the action! It is changed only the next (n+1) cycle (or n+2)! Is that a normal behaviour! Read/write of internal variable with SmartTags is not immediate? (Note: problem met with WString and int internal varaible) Thank you so much for you help. ------------------------------------------------------------------------------------------ |
