PID指令的操作
常规自动操作将在每次扫描时调用PID模块,有电流时为Enable,无电流时为Manual输人触点。该模块即把当前PLC逝去时钟与上次贮存在内部RetAray的PID解答时间进行比较。如果此时间差大于RefAray的定义在第3个字( %Ref + 2)采样周期的话, PID运算就用时间差进行解答,且把上次解答时间和控制变量进行刷新。
在Automatic方式下,输出CV置于手动命令参数%Ref+ 13中。如果同时为Enable和Manual输人触点送电,则PID模块置于Manual方式,输出CV从Man-ual Command参数%Ref+ 13中位。如果UP或DN中的一个通电;则Manual Command字在每次PID解答时进行逐一CV值的递增或递减。对于输出CV的更快的手动修改,直接或从Manual Command字进行加/臧CV值也是可能的。
