PPI协议是西门子为S7-200专门开发的通信协议，是不开放的协议。
CPU自带的两个通信口（Port0、Port1）均支持该协议，S7-200的一些通信模块也支持PPI协议。
编程软件Micro/WIN与CPU进行编程通信也使用PPI协议，编程下载必须使用配套的PPI线缆。
PPI是一种主从协议，CPU既可以做主站，又可以做从站。
主站靠PPI协议管理与从站通讯。
所有的通信程序运行在主CPU上，从站设备不需要专门的通信代码，根据主站的请求做出对应响应，实现CPU之间的数据交换。

Armored communication cable structure: 1. Basic cable: any filled and unfilled cable with single sheath or double sheath structure. 2. Armored communication cable mechanical protection layer: type 53 adopts 0.15mm thick corrugated steel belt, which is longitudinal wrapped on the basic cable and overlapped on both sides. The surface of the steel belt is coated with plastic to prevent corrosion and water intrusion. The type 23,22 has similar performance with double steel band wrapping. 3. Armored communication cable sheath: black high-molecular weight low-density polyethylene or polyvinyl chloride thin sheath. Sheath thickness may depend on the basic cable outer diameter. 4, identification and marking: cable appearance with permanent identification mark, tag, at no more than alternate 1 m intervals between 5, sheathed communication cable tag contents are: the diameter of wire, wire on the , type of cable, length, factory name and year of manufacture. 6. Armored communication cable electrical characteristics: the cable meets all the electrical re of the basic cable. 7. Cable length: mechanically protected cable is manufactured according to the standard length of the corresponding basic cable
四、动力电缆安装注意事项、使用特性及运行敷设条件1、动力电缆安装注意事项电缆与热力管道平行安装时保持2m的距离，交叉时应保持0.5m。
电缆与其它管道平行或交叉安装时均要保持0.5m的距离。
电缆直埋安装时，1-35KV电缆直埋深度不小于0.7m。
控制电缆的截面一般都不会超过10平方，电力电缆主要是输送电力的，一般都是大截面。
由于以上大家讲到的原因,电力电缆的规格一般可以较大，大到500平方(常规厂家能生产的范围)，再大的截面一般能做的厂家就相对少了，而控制电缆的截面一般较小，最大一般不超过10平方。

万用表电流档分为交流档与直流档两个，当测量电流时，必须将万用表指针打到相应的档位上才能进行测量。
交流档直流档在测量电流时，若使用mA档进行测量，须把万用表黑表笔插在COM孔上，把红表笔插在mA档上，如下图方框所示；若使用10A档进行测量，则黑表笔不变，仍插在COM孔上，而把红表笔拔出插到10A孔上，如下图方框所示。
电流测量注意事项如果使用前不知道被测电流范围，将功能开关置于最大量程并逐渐降低量程(不能在测量中改变量程)。
