With the script "Session Dataset": HMIRuntime.UI.DataSet.Add("UI_DS1",123); HMIRuntime.UI.DataSet.Add("UI_DS2",1234); for(let Index in HMIRuntime.UI.DataSet) { HMIRuntime.Trace("Value = "+HMIRuntime.UI.DataSet(Index)); } for(let Data of HMIRuntime.UI.DataSet) { HMIRuntime.Trace("Key = " +Data.Name + "Value =" + Data.Value); } I understand that i can read each value item from the dataset with "Data.Value", but if i want to write some value item, it goes wrong (Error on TracerViewer). I try it with for example Data.Value = 5, on the for function (The idea is all value items go to 5). But it doesnt works. I need some help with how to write on the value items of the DataSet object.

See section 5.6.3 Using client-internal tags via data set. I think the only option to update a tag value is to remove it using Remove method and create it again with the new value using Add method.
