11、表述网络传输速度的单位是什么？
表述网络传输速度一般以波特率（Bps）为单位，其含义是每秒钟传输的二进制数的位数。不同的网络一般波特率不同，相同的网络采用不同的网络电缆也可以达到不同的特率。例如：PROFIBUS现场总线在以双绞线作为网络电缆时通讯速度为1.5KBps，采用光缆时可以12MBps。采用普通双绞线的以太网传输速度为10MBps，采用光缆时可以达到100MBps。另外，传输距离的长短会影响传输速度，一般来说，距离越长，速度越慢。
12、什么是组态？
通过专用的软件定义系统的过程就是组态（configuration）。定义过程站各模块的排列位置和类型的过程叫过程站硬件组态；定义过程站控制策略和控制程序的过程叫控制策略组态；定义操作员站监控程序的过程叫操作员站组态；定义系统网络连接方式和各站地址的过程叫网络组态。
