It works fine, the only problem is if the new inputed value is equal the old value... In this case, nothing happens, because the object was not changed... Additionally, the "Tab order" can be corrected, so if the same value was inputed, the TAB key can be used to jump to the next field ! Best regards, Hello Celio, I have tested your script in WinCC V 7.5 but it won not work. Can you guide how select next IO filed when enter key is pressed or after barcode scan HMIRuntime.Screens("Temp Oven 01").ScreenItems("I/O Field31").Activate Error Got in Diagnostic Function. Error : get_Item:The parameter is incorrect. ============HMIScreens============ ============HMIScreens============ Application : Picture : Temp Oven 01.pdl_Events Function : Sub IX002FOX0020Field33_OnObjectChanged(ByVal Item) Line : 2 Error : get_Item:The parameter is incorrect. With Regards, Yogesh Patil ------------------------------------------------------------------------------------------ Split from Jump to the next field when "Enter" key pressed....

If you use an absolute path for the Screenitem with Screen Object then you have to consider also all used hierarchie of screen windows. If you use this script in the same screen as the next IO field is then you can only use ScreenItem("NameOfthe IO field").Activate (because you are already in the correct screen-context) Bye Murof
