SP000 简介：
物理层
物理层由国际电工委员会(IEC)与国际测量与控制协会(ISA)的标准来定义。
物理层从通讯栈接收消息，并将其转换成物理信号，然后发到现场总线的传送介质之上；物理层也负责这一过程的逆过程。
转换工作包括添加和去除前导码、开始定界符与结束定界符。
现场总线信号的编码使用曼切斯特双相-L技术。该信号称为“同步序列”，因为始终信息已加于串行数据流之上。数据和时钟信号结合在一起即产生现场总线信号。
现场总线信号接收端将时钟周期一半时的上跳沿解释为逻辑“O”，而将下跳沿解释为逻辑“1”。
我们也愿意参照其价格向您提供进一步的折扣。
只要您诚心购买，如果还有其他任何问题，请随时与我们联系。
我们的使命是帮助你!
