IC693PCM311RR 过程控制

过程控制是指对温度、压力、流量等模拟量的闭环控制，在冶金、化工、热处理、锅炉控制等场合有非常广泛的应用。作为工业控制计算机，PLC能编制各种各样的控制算法程序，完成闭环控制。PID调节是一般闭环控制系统中用得较多的调节方法，大中型PLC都有PID模块，目前许多小型PLC也具有此功能模块。PID处理一般是运行PID子程序。

数据处理

现代PLC具有数学运算（含矩阵运算、函数运算、逻辑运算）、数据传送、数据转换、排序、查表及位操作等功能，可以完成数据的采集、分析及处理。这些数据可以与存储在存储器中的参考值比较，进而完成控制操作；也可以利用通信功能传送到别的智能装置，或将它们打印制表。数据处理一般用于大型控制系统，如无人控制的柔性制造系统；也可用于过程控制系统，如造纸、冶金、食品工业中的一些大型控制系统。

通信及联网

PLC通信含PLC间的通信及PLC与其他智能设备间的通信。随着计算机控制的发展，工厂自动化网络发展得很快，各PLC生产厂商都十分重视PLC的通信功能，纷纷推出各自的网络系统。新近生产的PLC都具有通信接口，通信非常方便。纷纷推出各自的网络系统。新近生产的PLC都具有通信接口，通信非常方便。
