响应速度要求 PLC是为工业自动化设计的通用控制器，不同档次PLC的响应速度一般都能满足其应用范围内的需要。如果要跨范围使用PLC，或者某些功能或信号有的速度要求时，则应该慎重考虑PLC的响应速度，可选用具有高速I／O处理功能的PLC，或选用具有快速响应模块和中断输入模块的PLC等。 (五)系统可靠性的要求 对于一般系统PLC的可靠性均能满足。对可靠性要求很高的系统，应考虑是否采用冗余系统或热备用系统。 (六)机型尽量统一 一个企业，应尽量做到PLC的机型统一。主要考虑到以下三方面问题： １)机型统一，其模块可互为备用，便于备品备件的采购和管理。 ２)机型统一，其功能和使用方法类似，有利于技术力量的培训和技术水平的提高。 ３)机型统一，其外部设备通用，资源可共享，易于联信，配上位计算机后易于形成一个多级分布式控制系统。
