为基于 plc 的电机分配优先级的问题

Question

我想为数组中的每个元素分配一个唯一的优先级，但在下面的代码片段中，我为具有相同工作时间值的元素重复了相同的优先级 m。如何为每个元素设置唯一的优先级？

// assign priority number according to working times
#m := 0;
FOR #m := 0 TO 10 DO
    FOR #l := 0 TO 10 DO
        IF #OrderedList[#m] = #WorkingTimes[#l]."Time" THEN
            #WorkingTimes[#l].Priority := #m;
        END_IF;
    END_FOR;
END_FOR;

Answer 1

设置一些默认优先级，然后在更新元素时退出内部 FOR 循环

// assign priority number according to working times

FOR l := 0 to 10 DO
    WorkingTimes[l].Priority := -1;
END_FOR;

FOR m := 0 TO 10 DO
    FOR l := 0 TO 10 DO
        IF OrderedList[m] = WorkingTimes[l].Time AND WorkingTimes[l].Priority = -1 THEN
            WorkingTimes[l].Priority := m;
            EXIT;
        END_IF;
    END_FOR;
END_FOR;

我还没有测试过这个，但这个概念应该可行。
