  • Process of operating a numerical control with critical-time and non-critical-time processes in a real time system
    Patent number: 5909371
    Abstract: In a real-time system of a digital control system, in order to prevent a single program sequence (PS2) of a non-time-critical computing process ("task") from using up a load-dependently disproportionate amount of the total computing time still available, the program sequence (PS2) is classified as a subordinate computing process (R14) that has a running-time limit (LZF). Sequences of program steps that are preferably not to be interrupted are in this case protected from interruption by a lock, the original running-time limit (LZG) being able to be run over only within predetermined limits.
