This is the control and counter of the 'sw load rollback timer'. When set to -1, the timer is stopped and disabled. When set to 0, the timer assumes an 'instant timeout'. Otherwise, this object will indicate the time left on the timer. The timer is automatically started whenever the software starts up following a software load activation. When this timer reaches zero, the 'sw load manager' of the system will roll back the software to its previous version.
