atvise has the option to set alarm limits using "Relative Nodes". This means that instead of setting up the limit of the alarms with a fixed number, you can use a Node to set the alarm limit.
If the user changes the value of the Node then it changes the alarm limit.
When you create the alarm all you have to do is expand to the advanced settings of the condition and the limits will let you choose "Relative Node", there you can select the Node.
If you are working with vertical objects, it is important that the alarm limit nodes exists withtin the Node you are alarming. Otherwise when you create the object instances it won't work.
