在PLC系统规划时，首先应断定控制计划，下一步作业即是PLC工程规划选型。工艺流程的特色和运用请求是规划选型的依据。PLC及有关设备应是集成的、规范的，按照易于与工业控制系统构成一个全体，易于扩大其功能的原则选型所选用PLC应是在有关工业范畴有投运成绩、老练可靠的系统，PLC的系统硬件、软件装备及功能应与设备规划和控制请求相惯。熟悉可编程序控制器、功能表图及有关的编程言语有利于缩短编程时刻，因而，工程规划选型和预算时，应详细分析工艺进程的特色、控制请求，清晰控制使命和规模断定所需的操作和动作，然后依据控制请求，预算输入输出点数、所需存储器容量、断定PLC的功能、外部设备特性等，*终挑选有较高性能报价比的PLC和规划相应的控制系统。
一、输入输出(I/O)点数的预算
I/O点数预算时应思考适当的余量，通常依据计算的输入输出点数，再添加10%～20%的可拓展，余量后，作为输入输出点数预算数据。实践订购时，还需依据制造厂商PLC的商品特色，对输入输出点数进行圆整。
二、存储器容量的预算
存储器容量是可编程序控制器自身能供给的硬件存储单元巨细，程序容量是存储器中用户运用项目运用的存储单元的巨细，因而程序容量小于存储器容量。规划阶段，因为用户运用程序还未编制，因而，程序容量在规划阶段是不知道的，需在程序调试之后才知道。为了规划选型时能对程序容量有必定预算，通常选用存储器容量的预算来替代。
存储器内存容量的预算没有固定的公式，很多文献资料中给出了不一样公式，大体上都是按数字量I/O点数的10～15倍，加上模仿I/O点数的100倍，以此数为内存的字数(16位为一个字)，另外再按此数的25%思考余量。
