PROFIBUS提供了三种数据传输型式:RS-485传输、IEC1157-2传输和光纤传输。
(1) RS-485传输技术
RS-485传输是PROFIBUS常用的一种传输技术,通常称之为H2。RS-485传输技术用于PROFIBUS-DP与PROFIBUS-FMS。
RS-485传输技术基本特征是:网络拓扑为线性总线,两端有有源的总线终端电阻;传输速率为9.6kbps~12Mbps;介质为屏蔽双绞电缆,也可取消屏蔽,取决于环境条件;不带中继时每分段可连接32个站,带中继时可多到127个站。RS-485传输设备安装要点:全部设备均与总线连接;每个分段上多可接32个站(主站或从站);每段的头和尾各有一个总线终端电阻,确保操作运行不发生误差;两个总线终端电阻必须一直有电源;当分段站超过32个时,必须使用中继器用以连接各总线段,串联的中继器一般不超过4个;传输速率可选用9.6kbps~12Mbps,一旦设备投入运行,全部设备均需选用同一传输速率。电缆大长度取决于传输速率采用RS-485传输技术的PROFIBUS网络好使用9针D型插头。当连接各站时,应确保数据线不要拧绞,系统在高电磁发射环境下运行应使用带屏蔽的电缆,屏蔽可提高电磁兼容性(EMC)。如用屏蔽编织线和屏蔽箔,应在两端与保护接地连接,并通过尽可能的大面积屏蔽接线来复盖,以保持良好的传导性。
(2)IEC1157-2传输技术
IEC1l57-2的传输技术用于PROFIBUS-PA,能满足化工和石油化工业的要求。它可保持其本质安全性,并通过总线对现场设备供电。IEC1157-2是一种位同步协议,可进行无电流的连续传输,通常称为H1。
