问：是不是要用sm0.0调用这个ETH0_CTRL，然后这个块有CP Ready、CP Ready、Error,这三个是什么意思？怎么填？
答：首先你需要用STEP 7-Micro/WIN 软件，在Tools > Ethernet Wizard（以太网向导）中对CP243-1进行配置，为其设定IP地址、子网掩码等。
注意：要保证CP243-1和PC机的IP地址在一个网段上 。CP243-1模块不会自动适应电缆的接线方式，因此直接连接PC机网卡和CP243-1模块时，需要注意网线的类型。
在完成以太网向导后，会生成一个子程序
在程序中用SM0.0调用这个子程序 ,状态字CP Ready、CP Ready、Error的地址由用户指定，要注意不能与Ethernet Wizard（CP243-1）、Internet Wizard（CP243-1 IT）做配置时指定的V存储区重复。
将此程序下装到CPU中，然后将CPU重新上电，并运行，此时对以太网的配置开始生效。
后在MICRO/WIN软件中，进入Set PG/PC Interface，设定为TCP/IP通信接口，即可进入Communications（通信）中与CPU编程通信。
问;我现在有一个隔离模块，输入端是二线制传感器，输出端接入PLC中，无法显示；厂家技术说由模拟量模块的端子供回24V电，由输出端反馈电至隔离模块的输入端，带动变送器产生信号，我试了S7-200和300模块，就是不行，麻烦高手指点一下！！
答：1、选用支持2线制电流输入信号的模拟量输入模块，300中有该类模块，可在硬件配置中选择2线制电流信号。200的不支持2线制电流信号。
2、在只支持4线制电流输入信号的模块的通道中串入外部24V电源。
问：现场条件:CPU:315 2PN/DP CP:345-2 16块I/O卡 4块ET200M 其他如背板,电源,底座
等等之类的都全,完全可以组成一套PLC.
在测试中,没有加入冗余软件包前PLC运行正常(既单CPU运行正常).
后加入软件冗余包,并且按照官网的示例调用相关程序.
先下载A机PLC重起后运行正常 无SF报警
但是B机下载后PLC运行不起来,监视CPU也没提示错误是什么. 请大虾们指点.
答：这个问题范围太广，由于软件冗余中会使用一些特殊功能的DB块，在FC100“SWR—START”（冗余初始化）中定义，如DB1、DB2、DB3、DB5、DB31，检查这些数据长度等设定是否有问题；同时在FC100 的参数设定中，MPI_ADI 表示对方MPI地址，对于MPI同步有效；LADDR和 VERB_ID分别对应PROFIBUS和ETHERNET（以太网）同步有效，分别代表同步CP的硬件地址和连接；
非冗余DB不要手动创建，程序自动产生，A-B和B-A的DB同时使用，不能只有一个方向；
过程映像区不要大于CPU允许范围，如果不使用，可以设定为0
FC100“SWR—START” 在CPU启动会生成相关的数据块DB，在修改参数后删除旧的DB，否则CPU会停机。
S7-300/400的过程映像分区与中断功能配合，可以显著地减少PLC的输入、输出响应时间。过程映像区分为OB1（主程序）过程映像（OB1-PI）和过程映像分区（PIP）。
1．OB1过程映像
OB1过程映像就是普通的PLC的输入、输出区。PLC采用循环执行用户程序的方式，每次循环CPU将OB1过程映像输出区的数据写到输出模块；读取输入模块的输入状态，保存到OB1过程映像输入区；然后执行用户程序。这种工作方式不能马上将逻辑运算得到的输出点的值送输出模块，使用的输入点的状态也不是新的，因此造成了输入、输出的响应延迟。
2．过程映像分区
可以为S7-400的输入/输出地址分配多15个过程映像分区 (PIP)。
在硬件组态时，将一块输入模块和一块输出模块组态为属于某个过程映像分区，例如PIP1（见下图）。
打开CPU的属性对话框，在“时刻中断”选项卡，将过程映像分区PIP1分配给OB10（见下图）。
在调用OB10时，CPU首先自动读入被组态为属于过程映像分区PIP1的输入模块的输入值，然后执行OB10中的程序。执行完后，输出值被立即写至被组态为属于PIP1的输出模块。上述过程能保证得到小的输入、输出响应时间。
除了上述的在调用OB时的过程映像分区更新方式之外，还可以在用户程序中调用SFC 26 (UPDAT_PI) 和SFC 27 (UPDAT_PO)来更新过程映像分区。
