3D04153G05优势来袭

控制处理能力的另一个指标，运算速度，在人们印象当中PLC也比DCS要快很多。从某一个角度来看，情况也的确如此，PLC执行逻辑运算的效率很高，执行1K逻辑程序不到1毫秒，其控制周期(以DI输入直接送DO输出为例)可以控制在50ms以内;而DCS在处理逻辑运算和模拟运算时采用相同的方式，其控制周期往往在100ms以上。我们用PID算法来比较时，可以发现PLC执行一个PID运算在几个毫秒，而NETWORK6000+DCS的T2550控制器解算一个PID也需要1个毫秒，这说明PLC和DCS和实际运算能力是相当的,某此型号的DCS控制器甚至更强。而控制周期上的差异主要与控制器的调度设计有关。大型PLC往往使用副CPU来完成模拟量的运算，主CPU高速地完成开关量运算，所以即使模拟运算速度一般，在开关量控制方面的速度表现还是非常优秀的。而DCS以同样的速度来处理开关量和模拟量运算，控制周期的指标确实不理想。新型的DCS控制器学习了大型PLC的设计，在控制周期方面的表现获得了大幅度的提高。以NETWORK6000+DCS的T2550控制器为例。控制器可以设置四个不同优先级的任务，zui小运算周期可以设为10ms，配合高速I/O卡件，控制周期能够达到15~20ms。而模拟量运算设置在其它周期较长的任务中。
