特殊继电器区 ( Special Relay ) SR区
特殊继电器区简称SR区，用于监视PLC系统工作状态、产生时钟脉冲、产生错误信息等。SR区的通道寻址范围是251-255，SR区各继电器的状态一般是由系统程序自动写入，用户只能读取，有些位用户可自行设置。SR区既可以CH，也可以bit访问。下面列出了部分SR区常用标志位及其功能。
25l00：多个远程I／0单元故障标志。当多个远程I／0单元故障时，该位被置1。
25103：单个远程I／0单元故障标志。当一个远程I／0单元或光传输单元故障时，该位被置l。
25104：远程I／0从单元故障标志。该位被置1表示高通道位单元故障，该位被置0表示低通道位单元故障。与25100或25103等位标志合用。
25105，25106：光传输单元故障标志。通过这两个位，能表示0～3共4个光传输单元的故障位置。
25l07：远程I／0主单元故障标志。
25108～25115：故障通道标志。对远程I／0单元、光传输单元和I／0链接单元的故障通道进行标志。
25211，25206：分别是第0号和第1号主机链接单元链接错误标志。
25213，25207：分别是第0号和第1号主机链接单元重新启动标志。
25208，25209：分别是CPU安装型主机链接单元链接错误和重新启动标志。
25212：数据保持标志。可编程序控制器在监控或运行状态时，如该位被置1，则I／0继电器区、IR区和LR区内的数据(25212被置位时的数据)被保持。
25215：输出禁止标志。该位被置1，所有输出单元的输出信号被禁止输出。通过0UT指令可使该位置l。掉电时，该位保持掉电前的状态。该位置0时，对输出单元的输出进行正常更新。
25300～25307：故障代码输出标志。
25308：电池电压不足标志。
25309：扫描时间错误标志。当扫描时间大于系统***大限值时，该位被置l。
25310：I／0校验出错标志。I／0单元地址与已存放的I／0单元地址不符时，该位被置1。
25313：常ON标志。PLC通电后始终为1。
25315：***次扫描标志。在用户程序***次执行时置1，扫描结束以后置0。
25407：步进启动标志。步进指令STEP***次执行时置1，扫描结束以后置0。
25415：特殊I／0单元故障标志。系统中任何一个特殊I／0单元故障时，该位被置l。
25400： 1分钟时钟脉冲标志。用于产生脉冲周期为1分钟的时钟脉冲。脉冲的占空比为1：1。
25401：0.02秒时钟脉冲标志。用于产生脉冲周期为0.02秒的时钟脉冲。脉冲的占空比为1：1。
25500：0.1秒时钟脉冲标志。 用于产生脉冲周期为 0.1秒的时钟脉冲。脉冲的占空比为1：1。
25501：0.2秒时钟脉冲标志。 用于产生脉冲周期为0.2秒的时钟脉冲。 脉冲的占空比为1：1。
25502： 1 秒时钟脉冲标志。 用于产生脉冲周期为 1.0秒的时钟脉冲。脉冲的占空比为1：1。
