DDE projects

An RSLinx Classic DDE project is a storage container for one or more DDE topics. By grouping topics together in a project, you can make multiple topics available at the same time. It is best to add all topics for a given scenario to a specific project. Grouping your topics into projects allows you to use fewer computer resources, as loading a project with only the topics you use for a specific acquisition or report uses less resources than it would take to load all of your topics.
