Operating system for real=time task management, e.g. for robot and numerical control

摘要

The real-time operating system has a number of priority levels assigned (E0-E31) that has a related number of tasks (T1-T20) each with a two stage priority (PR10 XY). The first digit (X) denotes the sequence priority and the second, the priority at this level. Highest level priority is assigned to the level 0 and an active indicator is provided. A start-wait loop (SWO-SW31) is assigned to each level to control the execution of tasks within each level.
