Task Execution
任务执行
This sub-section describes priority,
interval time and offset for task execution. The next sub-section,
Overrun and Latency on page 178, describes handling of too long
task executions, delays, and load balancing etc.
此节描述优先级、间隔时间和偏移量。下一小节，第178页溢出和延时，描述任务执行时间过长、延迟和负载均衡等的处理。
There are four important task
parameters that can be set to optimize
program execution:
这里有四个重要任务参数可以设置用于优化程序执行：
- Priority, which sets the
execution order for tasks, see sub section Priority
below.
优先级，用于设置任务执行顺序，见下面小节选择优先级。 - Interval time, sets the task intervals during the program is executed, see sub section Interval Time on page 172. 间隔时间，设置程序执行的时间间隔，见第172页间隔时间小节。
- Offset, a parameter that helps you to avoid unexpected delays in execution when tasks are scheduled to execute at the same time. See sub section Offset on page 173. 偏移量，该参数帮助你避免因任务按照计划同时执行的意外延时。见第173页延时小节。
- Execution time, for best real
time behavior and communication performance, avoid extensive
continuous execution. See Execution Time on page 178 and also
Communication Considerations on page 176.
执行时间，为了获得最佳的实时行为和通讯性能，避免大量连续执行。见第178页的执行时间，以及第176页的通讯注意事项。
All POUs connected to a task execute
with the same priority, interval time,
offset, and
execution time.
所有链接到任务的POU（程序组织单元）都有相同的优先级、间隔时间、偏移量和执行时间
