what is the difference between Perspective session and Perspective module ? my understanding is that the perspective module has a limited and unlimited edition that limits the number of concurrent users.
What does the perspective single session limit? Is it the number of tabs in a browser for a user session? or does it limit multiple instances of a project in multiple browsers?
Perspective module is the visualisation module, you need this to have the perspecitve HMI.
Sessions are often based on device, not tabs or windows really. So if you had one session on your license allowed, this would basically mean only one PC or mobile phone can connect at any time.
Because perspective can be accessed from browsers and not specific software, this means if you close your browser someone else can then use it, its not locked to a single PC.
