plccpu负责开关量、模拟量的采集、运算，实施直接的控制功能;通讯模块cmm311通过两个通讯口分别连接上位机及触摸屏，实现人机界面与plc的数据通讯;pcm模块的com2与westinghouse（西屋仪表）mintii网络转换器相连，负责通过mintii网络转换器与现场三个种类的12台westinghouse仪表通讯，采集电流、电压、功率等各种物理量的实时数据，同时，com1在调试完毕后用来与现场一台三菱fx2nplc通讯，实现从geplc系统到fx2n系统的数据通路，方案图如图1所示。
2.1minitii转换器通讯协议简介

在这个方案中，minitii与下位设备的硬件连接为双绞线，minitii及下位各设备都并入双绞线组成的westinghouseincom网络，在该网络中各通讯主体使用二进制通讯方式，数据帧均由33位二进制数构成，minitii充当主站（master）角色，对下位各设备发起通讯，进行轮询。
pcm311模块与minitii转换器进行的是ascii码通讯方式，而minitii转换器与下位dt3000、mp3000、iq200各系列设备的通讯方式为二进制码通讯，实际上minitii所起到的作用是将pcm模块发出的ascii码指令帧转译为二进制码指令帧，当然，在通讯过程中，我们只需关心ascii码通讯帧的格式，minitii会自动将其转为二进制格式后发到incom网络中去。
