(3)用户存储器
用以存放用户程序即存放通过编程器输入的用户程序。PLC的用户存储器通常以字(16位/字)为单位来表示存储容量。同时,由于前面所说的系统程序直接关系到PLC的性能,不能由用户直接存取。因而通常PLC产品资料中所指的存储器型式或存储方式及容量,是对用户程序存储器而言。
常用的用户存储方式及容量型式或存储方式有CM0SRAM,EPR0M和EEPR0M。信息储存常用盒式磁带和磁盘。
CM0SRAM存储器是一种中高密度、低功能、价格便宜的半导体存储器,可用锂电池作为备用电源。一旦交流电源停电,用锂电池来维持供电,可保存RAM内停电前的数据。锂电池寿命一般为1―5年左右。

EPR0M存储器是一种常的只读存储器,定入时加高电平,擦除时用紫外线照射。PLC通过写入器可将RAM区的用户程序固化到R0M盒中的EPR0M中去。在PLC机中插入R0M盒,PLC则执行R0M盒中用户程序;反之,不插上R0M盒,PLC则执行RAM区用户程序。
EEPR0M存储器是一种可用电改写的只读存储器。
