西门子 200plc 通过 modbus 协议与组态王通讯，需要注意哪些事项？
需要注意如下几点：
1）需要向 PLC 中下载对应的初始化程序（KVmoddbus.mwp），由亚控提供。此程序默认的 plc 通讯端口为 port0，地址为 2，波特率 9600，无校验（地址和波特率可由程SBR0 中的 VB8，SMB30 进行修改）；
2）由于 PLCModbus 协议程序占用 V1000 及以前的地址，所以用户在编写逻辑控制程序中用到的寄存器不能和亚控提供的协议中所占用的 V 区地址冲突；
3）西门子 S7200PLC 和通过 modbus 协议和组态王通讯时，CPU 上的开关必须拨在RUN 状态，否则 PLC 中的 modbus 通讯程序没有处于运行状态，组态王和设备通过自由口协议肯定通讯失败。
