DHCP
- 常见的小型网络中（例如家庭网络和学生宿舍网），网络管理员都是采用手工分配IP地址的方法，而到了中、大型网络，这种方法就不太适用了。在中、大型网络，特别是大型网络中，往往有超过100台的客户机，手动分配IP地址的方法就不太合适了。DHCP（DynamicHostConfigurationProtocol）为我们解决了这一难题. -Common small networks (such as home networking and student dormitory network), networ

Siemens-PPI
- Siemens PPI协议分析 西门子S7-200 PLC之间或者PLC与PC之间通信有很多种方式:自由口，PPI方式，MPI方式，Profibus方式。使用自由口方式进行编程时，在上位机和PLC中都要编写数据通信程序。使用PPI协议进行通信时，PLC可以不用编程，而且可读写所有数据区，快捷方便。但是西门子公司没有公布PPI协议的格式。用户如果想使用PPI协议监控，必须购买其监控产品或第三方厂家的组态软件。这样给用户自主开发带来一定困难，特别是自行开发的现场设备就不能通过PPI协议接入PLC
