If there is already an application on the CPU, depending on the differences between the projects, the following options will
be presented:
Login with online change: execute the login and send the new project without stopping the current CPU application
(see Run Mode item), updating the changes when a new cycle is executed.
Login with download: execute the login and send the new project with the CPU stopped (see Stop Mode). When the
application is initiated, the update will have been done already.
Login without any change: executes the login without sending the new project.

In the online changes is not permitted to associate symbolic variables mapping from a global
