Your CCS License includes supervisor and wallboard license slots that limit the number of Supervisor and Wallboard Apps you can run across the LAN at any one time. The basic online CCS License includes 1 supervisor license and 1 wallboard license, but you can add additional supervisor and wallboard licenses if you require them. They are not interchangeable, you can't open the Supervisor App using a free wallboard license slot or vice versa.

 

The Supervisor, Monitor and Administrator Apps all require a supervisor license, but you can open all three Apps in the same browser at one time using just a single supervisor license slot. You will have to log on once, in the first App you load, but afterwards the other Apps will use the active application key details stored in LocalStorage from the first logon to auto-logon.

 

The Wallboard App uses wallboard license slots, of course, but even if you open the Wallboard App in a browser that already has an active Supervisor App with it's own application key, you will still need a free wallboard license slot to log on.

 

When you first log on to a CCS App in your browser the CCS Web Server will issue an application 'key' for the CCS License slot associated with the App, whether Supervisor or Wallboard. The key is then included in all http calls from the App to the CCS Web Server for license authentication. This key will be valid for all tabs and windows opened in the same browser, so although the CCS Apps are all designed as single page applications and do not open different tabs or windows during normal use, you can open multiple tabs manually that all reference the same CCS App URL if you want. This means, for instance, that it's possible to have two CCS Monitor App windows open in the same browser at one time, or two CCS Wallboard Apps if you choose.

 

These multiple windows, or sessions, are all 'sandboxed' inside the browser which means they all reference the same data space, and they all use the same application key issued during the initial log on. What's valid for one is valid for all. You only use a single CCS License slot but you have several versions of the App open in the browser.

 

However, this is not true if you open two different browser, say Internet Explorer and Google Chrome, on the same PC and then open the same CCS App in both. In this case, the CCS Web Server issues two separate application keys, using up two CCS licenses. There is no crossover between different browsers.

 

Closing the browser or navigating away from the CCS App URL is not the same as logging off, active licenses remain active when this happens, but they are treated slightly differently depending on whether they are Supervisor licenses or Wallboard licenses. Wallboard licenses always remain 'active' until they are either revoked manually or deliberately logged off. When you enter the Wallboard App URL into your browser, the App will first check to see whether the application key details in browser LocalStorage are associated with an active license slot and if so will continue without requiring you to logon again. This is so that you can include the browser in the PC's start-up process and get the Wallboard App to open up automatically when the PC is rebooted. Supervisor licenses remain active as long as you have a browser window open on the App's URL, but if you close the browser or navigate away without specifically logging off, a Supervisor license remains active for only 30 minutes before it is automatically revoked by the CCS Web Server.
