configure login/logout

Hi everyone,

Is possible to monitor when an user is logged?

For example:

When an user is logged any variable that I have to change to 1 and it to do logout the same variable go to 0.

If it's possible, I can bind this variable to my PLC and to realize the time control for there.

I would like to monitor how many time my user is active on my mashup and I do not know how to do it into thingworx
