But I am unable to get required result. Program shows no error or warning. I activated script using clock pulse. Please see below picture and advice where could be error. ------------------------------------------------------------------------------------------ Split from Add value of tags in winCC using Vb scritp .

Cyclic continuous is a term which is used in logging tags. Do I need to add these tags in logging tags to get result of their addition..?

Im not sure if the tags also be actualized if they are used in a script. But with continous acquisition it should work anyway Bye Murof
