The DeltaV controller balances memory and CPU capacity with Device Signal Tag (DST) licensing limits. It is possible to exceed a controller's memory and CPU capacity even if the controller license supports the number of DSTs in the control strategy. However, for a typical application in a wet process industry, the configuration engineer should be able to implement the required control strategies up to and including the DST license limit of the given controller.
Following are some guidelines to help deliver the maximum controller CPU performance.
