摘要：
A field control device is provided. The field control device includes: a task executing unit configured to selectively and sequentially execute a control task relating to a field control and other tasks in a same control period; and a priority switching unit configured to switch a relative priority of the control task relative to the other tasks in the control period, wherein the priority is a priority of an execution sequence of tasks in the task executing unit. The priority switching unit is configured to: i) set the priority higher than a certain priority, before the control task is started; and ii) set the priority lower than the certain priority, after the control task is ended.
摘要（中）：
提供现场控制装置。 现场控制装置包括：任务执行单元，被配置为在相同的控制周期中选择性地并且顺序地执行与场控制和其他任务相关的控制任务; 以及优先级切换单元，被配置为在所述控制周期中切换所述控制任务相对于所述其他任务的相对优先级，其中所述优先级是所述任务执行单元中的任务的执行序列的优先级。 优先切换单元被配置为：在控制任务开始之前，将优先级设置为高于特定优先级; 并且ii）在控制任务结束之后将优先级设置为低于该优先级。
