这里的A/D中的A,多为电流,或电压,也有为温度。D/A中的A,多为电压,或电流。电压、电流变化范围多为0~5V,0~10V,4~20mA。有的还可处理正负值的。
这里的D,小型机多为8位二进制数,中、大型多为12位二进制数。
A/D、D/A有单路,也有多路。多路占的输入输出继电器多。
有了A/D、D/A单元,余下的处理都是数字量,这对有信息处理能力的PLC并不难。中、大型PLC处理能力更强,不仅可进行数字的加、减、乘、除,还可开方,插值,还可进行浮点运算。有的还有PID指令,可对偏差制量进行比例、微分、积分运算,进而产生相应的输出。计算机能算的它几乎都能算。
这样,用PLC实现模拟量控制是完全可能的。控制的单位值可小到212分之一的测量程值,多数也是足够的。
PLC进行模拟量控制,还有A/D、D/A组合在一起的单元,并可用PID或模糊控制算法实现控制,可得到很高的控制质量。
用PLC进行模拟量控制的好处是,在进行模拟量控制的同时,开关量也可控制。这个优点是别的控制器所不具备的,或控制的实现不如PLC方便。
