MP277报警显示：区域指针类型时间日常期PLC地址错误！S7-300 314C-2DP PLC停止运行！请问高手是哪里出错了？
答：可以在PLC里面的模块信息里面查看故障提示
S7-200PLC收集一脉冲，脉冲频率200ms发送28个脉冲，程序最小扫锚周期175ms，用普通计数器CTU和INC计数结果偏小，用高速计数器结果偏高，脉冲输入点i0.0，请高手指点
答：首先对于这种频率较高的脉冲（约140Hz），脉冲宽度约7ms，对于你的扫描周期大于175ms的PLC程序，用普通计数器肯定不行，必须用高速计数器，而且脉冲不能接到PLC的普通输入模块的输入点I*.*，这种模块的输入信号是必须经过过程映像的，每个程序循环周期才刷新一次，达不到要求的，该脉冲信号必须直接接到高速计数器（硬件中断输入模块的输入端），才能准确计数。
欧姆龙PLC与其它仪表或设备通讯（无论是OMRON仪表或第三方仪表），要用带协议宏的串口通讯模块或模板，根据仪表或设备的通讯协议作相应的程序，建立相应的连通通道，就可对仪表进行读和写。
笔者曾为客户作过PLC与第三方温度仪表的通讯，现呈给各位，请指正。
所用PLC为OMRON C200HE-CPU42，配通讯模块C200HW-COM06，使用其A口（RS485）与温度表TTM-120通讯。
1、所用温度仪表“神王”TTM-120通讯协议：
EIA标准：RS485
通讯：站 1～31
传输：半双工
通讯码：ASCll 7位（BCC除外） 8位（MSD位=0）
接口方式：2线制
通讯速度：1200，2400，4800，9600
通讯距离：500Mmax
字符：启动位：1位
停止位：1/2位
数据：7/8位
校验：无/奇/偶
BCC校验：预先/不选择
通讯地址：1～99
通讯格式：
读数据：STX（02H 起始码）+地址（2位）+R+标识码（3位）+ETX（03H 结束码）
仪表返回：STX（02H 起始码）+地址（2位）+ACK（06H 响应）+标识码（3位）+数据（5位）+ETX（03H 结束码）
写数据：STX（02H 起始码）+地址（2位）+W+标识码（3位）+ 数据（5位）+ETX（03H 结束码）
仪表返回：STX（02H 起始码）+地址（2位）+ACK（06H 响应）+ETX（03H 结束码）
错误信息响应：STX（02H 起始码）+地址（2位）+NAK（15H 错误响应）+错误格式（1位）+ETX（03H 结束码）
2、用协议宏软件CX-PROTOCOL作协议宏程序
可用用CX-PROTOCOL中现有的系统标准协议COPY到新建的程序中，再作修改，当然也可重新编制。
在新建的程序的DEVICES中选择所用的PLC型号，
通讯口A参数设置方式为：PROTOCOL MACRO；并以仪表的通讯格式设置波特率等参数。
协议宏程序中有若干内容：主要是发送信息列表；接受信息列表；这两个表是协议宏的基本程序。再有就是具体的发送形式和接受形式，其它功能的读写形式,仪表的其它功能的读写形式。
我作了四种，根据仪表协议中的各个格式，编制宏程序，如下：
发送信息列表：
①写数据：SD（01）_1
<h>：STX
<t>：ETX
数据形式：变量格式（$（R（2）,5））
地址格式：ASCll变量格式（$（R（1）,2）
＂W＂：写请求
标识符（仪表功能参数:写入设定值）“空格SV”
数据格式：<h>+<a>+＂W＂+＂ SV＂+（$（R（2）,5））+<t>
② 读请求：SD（02）_1
地址格式：ASCll变量格式（$（R（1）,2）
＂R＂：读请求
标识符（仪表功能参数:读入过程值）“PV1”
数据格式：<h>+<a>+＂R＂+＂PV1＂+<t>
接受信息列表:
①接受响应：RV（01）_1
＂ACK＂：响应接受
数据格式：<h>+<a>+＂ACK＂+<t>
②接受数据：RV（02）_1
数据形式：变量格式（&（W（1）,＊）） 存入PLC指定的接收数据
数据格式：<h>+（&（W（1）,＊））+<t>
写入命令设置：
编号：050
命令：发送&接受
发送命令：SD（01）_1
接收命令：RV（01）_1
读入命令设置：
编号：051
命令：发送&接受
发送命令：SD（02）_1
接收命令：RV（02）_1
编制设置完成,下装到PLC中。
3、用CX-PROGRAMMER作通讯程序
程序用协议宏指令PMCR完成与仪表的通讯：
三个操作数：一：控制字：端口+协议宏序列号
二：发送数据首址 占2/3个字，首字是指令字数；下一字为仪表地址；
对于写命令要多一个字为设定值
三：接收数据首址 占4个字，首字是命令字数；下两字是接收的5位数据。
对于写命令该操作数为虚设字，没有实际意义
读指令：PMCR #1051 端口=1 序列号051（读出）
DM0000 DM0000=#0002 DM0001=#0001
DM0030 DM0030=#0004 DM0031～DM0033=数据
写指令：PMCR #1050 端口=1 序列号050（写入）
DM0020 DM0020=#0003 DM0021=#0001 DM0022=设置值
DM0040（虚设）
协议宏执行标志：端口一（A）：α机为IR289.08 CQM1H为IR207.08
端口二（B）：α机为IR289.12 CQM1H为IR207.12
当这变量=0时,方可执行PMCR命令
每个端口只能执行一个通信序列,可以不同的时间段产生PMCR指令的执行脉冲。
4、对于若干个仪表，每表设置不同的站号，就可由程序分别对其作读写操作，只有地址相符的仪表才能响应。
