Deploying several Information Models based on this specification on the same device may lead to the situation, that the same Variable(e.g., the Property SerialNumber) for the same device is used in several places.
When the Propertyis the same, and the value of the Propertyis the same, it is recommended to avoid, that the value is managed in the Serverin two different places (see Figure C.5, left). One solution is, that the two Variablesreference the same internal memory managing the value (see Figure C.5, middle). Another solution is, that the Variableis only managed once in the Server, just referenced from different places (see Figure C.5, right). The solution using the same Nodeis the most optimized one in terms of memory consumption.
