For the Duerr EcoTalk controller, create a Tool value named "1", then create a Base value named "1". Now, check the list of Tool values - the "1" has now disappeared.
Solution
In Ecotalk, like in ABB, tool, object, base are by name. And you cannot have 2 objects with the same name (in this case "1").
If you create a new tool data with the same name as an existing object data, then the existing object data will be overwritten.
This is why the tool "1" disappears from the tool list.
