1756-CNB/D 伺服轴卡

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zui核心工作，也是比较困难的一步，要设计好梯形图，首先要十分熟悉控制要求，同时还要有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，它的国际总部位于德国慕尼黑。西门子股份公司是在法兰克福证券交易所和纽约证券交易所上市的公司。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
