These versions have the feature to link the development workshop and the runtime of the application. They do not therefore allow to run multiple applications simultaneously. Their main advantage is their low cost, and the fact that you can leave on the installation, if you are a service provider, for example, the complete tool allowing to maintain and modify the application.
With these versions, you can acquire separately from the development licenses and the licenses of runtime. The development license allows you to design and build a complete application, and to run it (a runtime license is included in the license development). The license of runtime only allows you to operate the application, with all of the visualization tools and maintenance).
Versions limited in number of inputs/outputs
These versions have some limitations, mainly relating to the numbers of inputs/outputs. They allow you to create applications small and medium-sized without any problem.
