（1）内部专用继电器（SR） 内部专用继电器用于监视PLC的工作状态，
自动产生时钟脉冲对状态进行判断等。其特点是用户不能对其进行编程，
而只能在程序中读取其触点状态。
CPM1A系列PLC中常用的15个专用继电器及它们的具体编号和功能如下：
25200继电器：高速计数复位标志（软件复位）。
25208继电器：外设通讯口复位时仅一个扫描周期为ON，然后回到OFF状态。
25211继电器： 强制置位/复位的保持标志。在编程模式与监视模式互相
切换时，ON为保持强制置位/复位的接点；OFF为解除强制置位/复位的接
点。
25309继电器：扫描时间出错报警。当PLC的扫描周期超过100s时，1809变
ON并报警，但CPU仍继续工作；当PLC的扫描周期超过130s时，CPU将停止
作。
25313继电器：常ON继电器
25314继电器：常OFF继电器
25315继电器：第一次扫描标志。PLC开始运行时，25315为ON一个扫描周期，
然后变OFF。
25500~25502继电器：时钟脉冲标志。这3个继电器用于产生时钟脉冲，
可用在定时或构成闪烁电路。其中，25500产生0.1s脉冲（0.05sON／0.05sOFF）
，在电源中断时能保持当前值；25501产生0.2s脉冲(0.1sON／0.1sOFF)，
具有断电保持功能；25502产生1s脉冲(0.5sON／0.5sOFF)，具有断电保持
功能。
25503~25507继电器：这五个继电器为算术运算标志。其中，25503为出错
标志，若算术运算不是BCD码输出时，则25503为ON；25504为进位标志CY，
若算术运算结果有进位/错位时，则25504为ON；25505为大于标志GR，在执
行CMP指令时，若比较结果“＞”，则25505为ON；25506为相等标志EQ，在执
行CMP指令时，若比较结果“＝”，则25506为ON；25507为小于标志LE，在执
行CMP指令时，若比较结果“＜”，则有25507为ON。
（2）数据存储继电器（DM） 数据存储继电器实际是RAM中的一个区域，又
称数据存储区（简称DM区）它只能以通道的形式访问。CPM1A系列PLC提供的
读/写数据存储器寻址范围为DM0000~DM1023（共1023字），只读数据存储器
寻址范围为DM6144~DM6655（共512字）。编程时需要在通道号前标注“DM”，
DM区具有掉电保持功能。
