The Comat BoxX includes a real-time clock, whose calendar is already programmed until the year 2099. Special function blocks also allow the Comat BoxX to act as a perfect clock timer.

The program memory in the BoxX has space for up to 127 function blocks. This is more than adequate to implement even the most complex, time-dependent controllers.

The system clock, of course, can operate without external power for 100 hours.
