由于电磁干扰的复杂性，要根本消除迎接干扰影响是不可能的，因此在plc控制系统的软件设计和组态时，还应在软件方面进行抗干扰处理，进一步提高系统的可靠性。常用的一些措施：数字滤波和工频整形采样，可有效消除周期性干扰；定时校正参考点电位，并采用动态零点，可有效防止电位漂移；采用信息冗余技术，设计相应的软件标志位；采用间接跳转，设置软件陷阱等提高软件结构可靠性。
下面用一个简单的例子来进一步说明plc的扫描工作过程。图1-6给出了plc的外部接线图和梯形图，起动按钮sb1停止按钮sb2和热继电器fr的常开触点分别接在编号为x0~x2的plc的输入端，交流接触器km的线圈接在编号为y0的plc的输出端。图1-6b是这4个输入／输出变量对应的i／o映像寄存器，图l-6c是plc的梯形图，它与图1-3所示的继电器电路的功能相同。但是应注意，梯形图是一种软件，是plc图形化的程序。图中的x0等是梯形图中的编程元件，x0~-x2是输入继电器，y0是输出继电器。梯形图中的编程元件x0与接在输入端子x0的sbl的常开触点和输入映像寄存器x0相对应，编程元件y0与输出映像寄存器y0和接在输出端子y0的plc内部的输出电路相对应。
（2）确定所需的用户输入设备（按钮、操作开关、限位开关、传感器等）、输出设备（继电器、接触器、信号灯等执行元件）以及由输出设备驱动的控制对象（电动机、电磁阀等），估算plc的i/o点数；分析控制对象与plc之间的信号关系，信号性质，根据控制要求的复杂程度，控制精度估算plc的用户存储器容量。
商品经济的高速发展带动了商标印刷行业，而市场的激烈竞争迫使商标印刷行业在保证质量的前提下，最大限度地降低成本，在这样的背景下北京凯迪恩自动化技术有限公司采用凯迪恩国产plc协助某印刷机厂成功开发出可调长度轮转印标机，可使商标印刷厂商大幅节省材料从而降低印刷成本
（1）急停电路。对于能使用户造成伤害的危险负载，除了在控制程序中加以考虑之外，还应设计外部紧急停车电路，使得plc发生故障时，能将引起伤害的负载电源可靠切断。（2）保护电路。正反向运转等可逆操作的控制系统，要设置外部电器互锁保护；往复运行及升降移动的控制系统，要设置外部限位保护电路。
非通用性会导致系统的功能前景和开放性受到很大的限制。另外，plc的操作系统通常都是各plc厂家的专用操作系统，与目前流行的实时操作系统不兼容。由于是专用的操作系统，其实时可靠性与功能都无法与通用的实时操作系统相比，这就导致了plc的整体性能的专用性和封闭性
（2）输入/输出线不能用同一根电缆，输入/输出线要分开。
