根据已确定的用户 I/O 设备，统计所需的输入信号和输出信号的点数，选择合适的 PLC 类型，包括机型的选择、容量的选择、 I/O 模块的选择、电源模块的选择等。
( 4 )分配 I/O 点
分配 PLC 的输入输出点，编制出输入 / 输出分配表或者画出输入 / 输出端子的接线图。接着九可以进行 PLC 程序设计，同时可进行控制柜或操作台的设计和现场施工。
( 5 )设计应用系统梯形图程序
根据工作功能图表或状态流程图等设计出梯形图即编程。这一步是整个应用系统设计的核心工作，也是比较困难的一步，要设计好梯形图，要十分熟悉控制要求，同时还要有一定的电气设计的实践经验
西门子
西门子股份公司(SIEMENS AG FWB：SIE, NYSE：SI)是世界大西门子公司总部的机电类公司之一，1847年由维尔纳·冯·西门子建立。如今，它的总部位于德国慕尼黑。西门子股份公司是在法兰克福证券和纽约证券上市的公司。2005年，西门子全集团在190个国家和地区雇用员工460,800人，收入为754.45亿欧元(2004年为702.37亿欧元)，税后利润较2004年的36.6亿欧元降至24.2亿欧元。
 各个PLC的编程语言的指令设计、界面设计都不一样，不存在孰优孰劣的问题，主要是风格不同
