。***控制单元和下位机PLC之间采用串行通讯方式进行数据交换，通常距离在1000m以内选用485双绞线通讯方式，较常距离可选用光纤通讯，更长距离也可选用无线通讯方式。下位机选用PLC控制，根据控制对象的多少，控制对象的范围，可选用一台或多台PLC进行控制，PLC之间数据交换是利用内部链接寄存器，实现数据交换和共享。由于PLC对现场进实时监控具有很高的可靠性，且编程简单、灵活，因此越来越受到人们重视。
2、控制系统可靠性降低的主要原因
虽然工业控制机和可编程控制器本身都具有很高的可靠性，但如果输入给PLC的开关量信号出现错误，模拟量信号出现较大偏差，PLC输出口控制的执行机构没有按要求动作，这些都可能使控制过程出错，造成无法挽回的经济损失。
